Abstract
A 42-year-old woman visited our hospital with complaints of fever, muscle pain, and dyspnea one week after receiving the coronavirus disease 2019 (COVID-19) vaccine. Chest high-resolution computed tomography showed a patchy consolidation and ground-glass attenuation in the both lungs, consistent with acute interstitial pneumonia. Transbronchial lung cryobiopsy revealed organizing pneumonia with marked intra-alveolar fibrin, and pathologically diagnosed as acute fibrinous organizing pneumonia (AFOP). Other causative diseases such as dermatomyositis was clinically ruled out, and COVID-19 vaccine-induced AFOP was diagnosed. Physician should check the history of COVID-19 vaccination when encountering a case of AFOP with an unknown cause.

Abstract
BACKGROUND Urticaria mostly occurs acutely with a very high probability of spontaneous remission. When it persists for more than 6 weeks a chronic urticaria is manifest, which occurs either spontaneously or inducible by specific triggers. The underlying mechanisms are not fully understood but recent research points to defined pathogenetic factors. QUESTION AND AIM Whether spontaneous remission is possible in urticaria is summarized descriptively in this review, and suggestions are given for the "step down" of urticaria treatment after remission. The mechanisms including autoallergic, immunoglobulin E (IgE)-dependent type I reactions and autoimmune, activating IgG-dependent type IIb reactions are presented. These are discussed in the context of spontaneous remission and the possibilities of induced remission.

Abstract
OBJECTIVE Spontaneous regression of tumors is an attractive phenomenon that most commonly occurs in stage 4S neuroblastoma (NB). However, the mechanism underlying this phenomenon remains unclear. METHODS Datasets correlated with NB were downloaded from online public databases, the differentially expressed genes (DEGs) between stage 4 and 4S associated with immunity were identified, and functional enrichment analysis was utilized to explore the potential functions and signaling pathways of these DEGs. In addition, based on these DEGs, a prognostic signature was constructed and validated, and differences in immune cell infiltration were analyzed. RESULTS A total of 13 DEGs were finally identified, and functional enrichment analysis revealed that these DEGs were primarily enriched in the positive regulation of neuron differentiation and TGF-β signaling pathway. The signature successfully stratifies patients into two risk score groups and performs well in judging prognosis and predicting overall survival time. In addition, the prognostic value of the risk score calculated by the signature was independent of clinical factors. The results of immune cell infiltration showed that patients with a high infiltration of resting CD4 + memory T cells had a better prognosis, while plasma cells had a worse prognosis. CONCLUSION The results of the functional enrichment analysis of these identified DEGs suggested that these DEGs may be related to spontaneous regression of NB. In addition, the prognostic signature has the potential to create new risk stratification in patients with NB.

Abstract
Spontaneous remission is often observed in extracardiac cases of sarcoidosis, such as skin sarcoidosis. However, for cardiac sarcoidosis (CS), the prognosis is unfavorable. Although corticosteroids are the first-line treatment for CS, data regarding the natural history of isolated CS are limited. We describe a rare case of isolated CS with severe left ventricular systolic dysfunction that improved without steroid therapy.

Abstract
BACKGROUND This study examined the appropriateness of the current paradigm for differential diagnosis of painless thyroiditis and Graves' disease (GD) in patients with thyrotoxicosis. METHODS We retrospectively evaluated the clinical course of 343 consecutive patients with hyperthyroidism diagnosed by Tc-99m pertechnetate thyroid uptake (TcTU) testing at our hospital from January 2011 to December 2017. RESULTS Of the 263 patients with normal or high TcTU levels (≥1.0%), 255 (97%) had unequivocal GD and 5 had spontaneous remission GD or atypical GD. Of the 10 patients with low TcTU levels (<1.0% and ≥0.5%), 7 had GD, while others had subclinical GD, spontaneous remission GD with later relapse, and painless thyroiditis. Of those with very low TcTU levels (<0.5%), most had thyroiditis (painless thyroiditis, 33/67 [49%]; subacute thyroiditis, 29/67 [43%]), and some were positive for anti-TSH receptor antibodies. CONCLUSION Given that atypical GD may confound the diagnosis of thyrotoxicosis, it is essential to follow the patient as a tentative diagnosis, whatever the diagnosis. This is the first report clearly demonstrating that so far there is no gold standard for the diagnosis of GD. It is therefore urgent to establish a consensus on the definition of GD so that the specificity and sensitivity of future diagnostic tests can be determined.

Abstract
ABSTRACT In situ follicular B-cell neoplasm (ISFN) is a variant of follicular lymphoma, presenting as an incidental histologic finding in lymph node biopsy or excisional specimens. ISFN presents with a B-cell population that strongly expresses BCL2 and CD10 within the germinal centers of a lymph node or extranodal site. Genetic analysis shows t(14;18) translocation. Herein, we report a case of ISFN presenting as military and agminated facial papules in a young woman, which resolved spontaneously in the postpartum period. To our knowledge, this is the only report of a cutaneous site of involvement of this rare entity.

Abstract
OBJECTIVE To describe the hyperproliferation of Elschnig pearl-type posterior capsule opacification and concurrent uveitis in two canine eyes after phacoemulsification, followed by spontaneous resolution of the Elschnig pearls. ANIMAL STUDIED A 10-year-old castrated male Spitz (Case 1) and a 4-year-old spayed female Bichon Frise (Case 2). PROCEDURE Elschnig pearls proliferating beyond the anterior capsulotomy site were observed in the right eye 10 months after bilateral diabetic cataract surgery (Case 1) and 7 months after unilateral cataract surgery (Case 2). In both cases, hyperproliferation occurred where the anterior capsule did not overlap with the intraocular lens (IOL), and was accompanied by aqueous flare. In Case 1, the pearls extended from the anterior capsule and adhered to the iris, causing focal posterior synechia. No other possible causes of uveitis were apparent. RESULTS Initially, uveitis severity improved after the administration of topical and systemic anti-inflammatory drugs. However, uveitis recurred when the dosage of anti-inflammatory treatment was reduced. The Elschnig pearls underwent morphological changes throughout the follow-up period. In both cases, the pearls beyond the anterior capsulotomy resolved spontaneously after 5 months. Only a few pearls remained between the IOL and posterior capsule, and no recurrence of pearl proliferation was observed at the last follow-up. CONCLUSIONS To the best of our knowledge, this is the first report of spontaneous Elschnig pearl regression in dogs. Lens-induced uveitis (LIU) may have been caused by anterior chamber hyperproliferative pearls. LIU associated with hyperproliferative pearls may be managed with appropriate anti-inflammatory treatment and monitoring.

Abstract
An 8-year-old male neutered Miniature Schnauzer was diagnosed with diabetes mellitus based on fasting hyperglycemia and glucosuria after a 2-week history of polydipsia and periuria, in line with the Agreeing Language in Veterinary Endocrinology consensus definition. Treatment of insulin and dietary management was initiated. The insulin dose was gradually reduced and eventually discontinued over the next year based on spot blood glucose concentrations that revealed euglycemia or hypoglycemia. After discontinuation, the dog remained free of clinical signs for 1 year until it was again presented for polyuria/polydipsia with fasting hyperglycemia and glucosuria. Insulin therapy was resumed and continued for the remainder of the dog's life. Although diabetic remission often occurs in cats and humans, the presumed etiopathogenesis of pancreatic beta cell loss makes remission rare in dogs, except for cases occurring with diestrus or pregnancy. This case demonstrates that diabetic remission is possible in dogs, even in cases without an identifiable reversible trigger.

Abstract
RATIONALE Epstein-Barr virus mucocutaneous ulcers (EBVMCUs) were officially recognized as a clinicopathologic entity in the 2017 revision of the World Health Organization classification, which often occurs in the elderly or in immunosuppressive condition presented as an isolated ulcerative lesion. EBVMCUs are defined as "shallow, sharply circumscribed, mucosal or cutaneous ulcers with underlying polymorphous infiltration." It mostly involves oral mucosa, but some appear in skin or gastrointestinal tract. Typically, patients with EBVMCUs display a slow disease progression and may even undergo spontaneous regression. PATIENT CONCERNS This report describes the case of a 76-year-old woman who visited our outpatient clinic with the chief complaint of inflammation and ulceration on lower labial, lower right lingual gingiva seemed like acute necrotizing ulcerative gingivitis, and malignancy. DIAGNOSES She was diagnosed with EBVMCU after tissue biopsy. INTERVENTIONS Since most oral ulcerations usually appear in nonspecific form, it is important to check thoroughly for any underlying immunosuppressive systemic conditions and laboratory test results in case of viral infection. But she has no remarkable underlying immunosuppressive disorder. OUTCOMES For this patient, she was initially diagnosed with EBVMCU and showed spontaneous healing, but then relapsed after 4 to 6 months. The patient was re-diagnosed as EBV-positive diffuse large B-cell lymphoma (EBV-positive DLBCLs) after re-biopsy. LESSONS EBVMCU shows similar symptoms to malignant lesions or acute necrotizing ulcerative gingivitis but shows spontaneous healing. However, in case of EBV-positive DLBCLs, failing to detect and treat the disease in its early stages can lead to a fatal outcome. Thus, this case report highlights the differential diagnosis and appropriate treatment of EBVMCU and EBV-positive DLBCLs.

Abstract
BACKGROUND Uterine leiomyomas are hormone-dependent benign tumors and often begin to shrink after menopause due to the reduction in ovarian steroids. The influence of pregnancy on uterine leiomyomas size remains unclear. Here, we present a case of spontaneous regression of a giant uterine leiomyoma after delivery. CASE PRESENTATION A 40-year-old woman presented with multiple uterine leiomyomas, one of which is a giant uterine leiomyomas (approximately 8 cm in diameter) that gradually shrinked after delivery. At over two months postpartum, the large myometrial leiomyoma had transformed into a submucosal leiomyoma, and over 3 years postpartum, both the submucosal leiomyoma and multiple intramural leiomyomas completely regressed. CONCLUSION Spontaneous regression of a giant uterine leiomyom is rare after delivery. Considering uterine leiomyoma regression until over 3 year postpartum,we need to observe the regression of uterine fibroid for a longer time postpartum in the absence of fibroid related complications. In addition, it will provide new insights for treatment options of uterine leiomyomas in the future.

Abstract
ABSTRACT Despite extensive research into COVID-19 since its emergence in late 2019, there is still much not fully understood about its long-term effects. When infected with SARS-CoV-2, cancer patients have been reported to be at higher risk for unfavorable outcomes. Nevertheless, evidence suggests that viruses may exhibit an antitumor effect in some cases, which has recently been anecdotally reported with SARS-CoV-2. We present the case of a patient with a recent high-grade non-Hodgkin lymphoma diagnosis and without any cancer-specific therapy, in whom a complete metabolic response on 2-[ 18 F]FDG PET/CT was observed after COVID-19.

Abstract
AIM The present systematic review aimed to identify and summarize the clinical, radiographic, and histological outcomes of alveolar ridge preservation using bone xenografts and absorbable sealing materials compared with spontaneous healing in the esthetic zone. MATERIALS AND METHODS Randomized clinical trials (RCTs) fulfilling specific eligibility criteria were included. Two review authors independently searched for eligible studies, extracted data from the published reports and performed the risk of bias assessment (RoB 2 tool). Study results were summarized using random effects meta-analyses. RESULTS Thirteen articles concerning 10 RCTs were included, involving a total of 357 participants. Most of studies were considered as "low" risk of bias. Meta-analyses indicated less horizontal (difference in means-MD = 1.88 mm; p < 0.001), vertical mid-buccal (MD = 1.84 mm; p < 0.001) and vertical mid-lingual (MD = 2.27 mm; p < 0.001) bone resorption in alveolar ridge preservation compared to spontaneous healing as assessed clinically. Bone changes assessed radiographically showed consistent results in terms of horizontal (at 1 mm: MD = 1.84 mm, p < 0.001), vertical mid-buccal (MD = 0.95 mm; p < 0.001) and mid-lingual (MD = 0.62 mm; p = 0.05) resorption. Part of the bone resorption in the spontaneous healing group was compensated by soft-tissues, since the observed differences between groups in linear ridge reduction evaluated through cast models superimposition were smaller (MD = 0.52 mm; p < 0.001). CONCLUSIONS Alveolar ridge preservation with xenogeneic bone substitutes and non-autogenous resorbable socket sealing materials is efficacious in reducing post-extraction bone and ridge changes in the esthetic region.

Abstract
PURPOSE To evaluate the effects of prematurity and retinopathy of prematurity (ROP) treatment on choroidal structure using the image binarization method and compare with term children. METHODS Children aged 6-11 years were included in this prospective case-control study. There were 36 (72 eyes) term children and 52 (103 eyes) preterm children included in the study. Subfoveal choroidal thickness (SFCT) and choroidal thickness (CT) at 500, 1500, and 2500 μm temporal and nasal from the fovea were measured. Images were binarized using the Image J program. The choroidal vascularity index (CVI) was calculated by dividing the luminal area by the total subfoveal choroidal area. RESULTS There was no significant difference in SCFT between children born at term (290.44±57.617 μm) and preterm (288±69.270 μm) (p = 0.800). CVI was found to be significantly higher in term children (71.90±2.60 %) than in preterm children (69.58±2.72 %) (p<0.001), and the difference was also significant when compared to preterm children without ROP (p = 0.033). In the preterm subgroups, although CVI was higher in preterm children without ROP (70.42±2.24 %) than in those with spontaneous regression (69.34±3.30 %) and those treated with laser photocoagulation (68.91±2.35 %), there was no significant difference (p = 0.330, p = 0.089 respectively). CVI was similar between children with spontaneous regression and those treated with laser photocoagulation (p = 0.909). CVI and logMAR best corrected visual acuity (BCVA) were inversely correlated (r=-0.295 p<0.001). CONCLUSION Reduced CVI in preterm children indicates that prematurity is related to the choroid. Choroidal vascularity index appears to be a more reliable marker than CT for evaluating the relationship between choroid and ROP.

Abstract
Spontaneous regression of non-small cell lung cancer is relatively rare. Here, we present a very rare case of spontaneous regression of lung cancer which occurred in a patient with basaloid squamous cell lung cancer. To the best of our knowledge, this is the first report of such a case. A 76-year old man was referred to our hospital with nodules in the right upper lobe determined by chest computed tomography. The nodules spontaneously regressed during follow-up. Two years later, the tumor had regrown and the patient subsequently underwent surgery. The pathological findings showed basaloid squamous cell carcinoma. Stimulation of the immune system was considered to be the cause of the spontaneous regression and CD-8 positive and CD-4 positive lymphocytes might play an important role.

Abstract
Monosomy 7 is the most common cytogenetic abnormality in pediatric myelodysplastic syndrome (MDS) and associated with a high risk of disease progression. However, in young children, spontaneous loss of monosomy 7 with concomitant hematologic recovery has been described, especially in the presence of germline mutations in SAMD9 and SAMD9L genes. Here, we report on our experience of close surveillance instead of upfront hematopoietic stem cell transplantation (HSCT) in seven patients diagnosed with SAMD9L syndrome and monosomy 7 at a median age of 0.6 years (range, 0.4-2.9). Within 14 months from diagnosis, three children experienced spontaneous hematological remission accompanied by a decrease in monosomy 7 clone size. Subclones with somatic SAMD9L mutations in cis were identified in five patients, three of whom attained hematological remission. Two patients acquired RUNX1 and EZH2 mutations during the observation period, of whom one progressed to myelodysplastic syndrome with excess of blasts (MDS-EB). Four patients underwent allogeneic HSCT at a median time of 26 months (range, 14-40) from diagnosis for MDSEB, necrotizing granulomatous lymphadenitis, persistent monosomy 7, and severe neutropenia. At last follow-up, six patients were alive, while one passed away due to transplant-related causes. These data confirm previous observations that monosomy 7 can be transient in young children with SAMD9L syndrome. However, they also indicate that delaying HSCT poses a substantial risk of severe infection and disease progression. Finally, surveillance of patients with SAMD9L syndrome and monosomy 7 is critical to define the evolving genetic landscape and to determine the appropriate timing of HSCT (clinicaltrials gov. Identifier: NCT00662090).

Abstract
A 71-year-old man was diagnosed as having right primary lung squamous cell carcinoma, clinical stage IIIA, but he refused treatment. However, the right upper lobe nodule and lymph node (LN) #4R showed gradual shrinking without treatment. Four years after the diagnosis, a new nodule was detected in the left lung field. We considered that this new nodule might be metachronous primary lung cancer, and hence resected it for diagnosis and treatment. The tumor in the left lung was diagnosed as basaloid squamous cell carcinoma, and that in LN #4R was diagnosed as squamous cell carcinoma with keratinization. Therefore, the patient was diagnosed as having metachronous primary lung cancer that developed during the spontaneous regression of locally advanced lung cancer.

Abstract
Pulmonary large cell neuroendocrine carcinoma (LCNEC) is a rare and aggressive subtype of non-small cell lung cancer with a poor prognosis. Spontaneous regression, that is, partial or complete disappearance of a malignancy without medical intervention, is extremely rare in LCNEC. Herein, we present a case of spontaneous complete regression in a 71-year-old male patient with recurrent LCNEC after surgical resection. The patient was diagnosed with stage IB LCNEC and underwent surgical resection. At 1-year follow-up, chest computed tomography revealed a recurrent lesion next to the stump site and enlargement of lymph nodes 4R and 7; recurrent LCNEC was confirmed. The patient declined chemoradiation therapy. One year after recurrence, the patient experienced severe multifocal necrotizing pneumonia and was treated with antibiotics, resulting in a gradual decrease in the size of the recurrent lesion. Five years after the initial diagnosis, positron emission tomography/computed tomography revealed no hypermetabolic lesions, indicating the spontaneous complete regression of LCNEC.

Abstract
OBJECTIVE Peripheral precocious puberty (PPP) is the precocious development of secondary sexual characteristics without pulsatile gonadotropin-releasing hormone (GnRH) secretion. In girls, PPP suggests a hyper-oestrogenic state, such as autonomous ovarian cysts and McCune-Albright syndrome (MAS). We aimed to investigate PPP in girls with ovarian cysts, with or without MAS. DESIGN A retrospective study design was used. PATIENTS AND MEASUREMENTS The study included 12 girls diagnosed with ovarian cysts with PPP between January 2003 and May 2022. Pelvic sonography was performed in cases of vaginal bleeding or areolar pigmentation in PPP. The clinical characteristics, clinical course and pelvic sonographic findings of girls with ovarian cysts were investigated. RESULTS We found 18 episodes of ovarian cysts in the 12 girls. The median size of the ovarian cysts was 27.5 mm. Five of the girls were diagnosed with MAS. The median time to spontaneous regression was 6 months. Later, 4 out of 12 girls progressed to central precocious puberty (CPP), and three of them had a recurrence of ovarian cysts. Compared to the non-recurrent and recurrent groups, there was a difference in peak luteinizing hormone (LH) in the GnRH stimulation test and period to cyst regression. CONCLUSIONS Most ovarian cysts in PPP spontaneously disappear. However, this could be one of the findings of MAS. Some girls progress from PPP to CPP. Therefore, follow-up is necessary for ovarian cysts in patients with PPP. The recurrence of ovarian cysts may occur when spontaneous regression is prolonged.

Abstract
OBJECTIVE The incidence of scrotal migration of a ventriculoperitoneal shunt (VPS) catheter is rare and may lead to life-threatening visceral complications. Management requires prompt removal of the migrated portion of the shunt and closure of the scrotal sac. We report an interesting case of a young child who presented with asymptomatic unilateral swelling of his scrotum secondary to a migrated VPS catheter. A repeat X-ray prior to his surgery to remove the migrated catheter showed that the entire length of the distal VPS catheter was back in the peritoneal cavity. In view of this unusual phenomenon, the case is discussed in corroboration with published literature. METHODS AND RESULTS A systematic search of publications in the English language is performed in PubMed and Google Scholar. Our findings show that there are 49 reported cases (including our patient) of scrotal migration of shunt catheters in patients less than 18 years old. There is only 1 other case of spontaneous resolution of shunt catheter from the scrotum. Favoured management of choice is repositioning the distal shunt catheter back into the peritoneal cavity and herniotomy in the same setting, if possible. Overall, the literature suggests this is a shunt-related complication that has a good prognosis if intervention is timely. CONCLUSION Scrotal migration of a VPS catheter is a rare but potentially life-threatening complication in children. Our case report highlights the role of updated preoperative imaging and the need for consistent long-term shunt surveillance in children.

Abstract
A 24-year-old man was found to have an ileocecal ulcer by colonoscopy. A pathological diagnosis of diffuse large B-cell lymphoma (DLBCL) with diffuse positive reaction of Epstein-Barr encoding region (EBER) by in situ hybridization was made based on analysis of the specimen. Acquired immunodeficiency syndrome (AIDS) complicated by pneumocystis jirovecii pneumonia was also diagnosed. As no other significant lymphomatous lesions were identified by further examination, a clinical diagnosis of EBV-positive mucocutaneous ulcer (EBVMCU) was made. Rather than performing systemic chemotherapy, the lesion was closely monitored and antiretroviral therapy (ART) for AIDS was started with the hope of treating the lesion through immune reconstitution. The lesion had completely disappeared by day 79 after starting ART, and has not recurred for over 3 years. EBVMCU is known to develop secondary to various immunosuppressive states including AIDS. Here we report a rare case of EBVMCU detected at diagnosis of AIDS that entered complete remission after immune reconstitution by ART.

Abstract
BACKGROUND/OBJECTIVES Progression of retinopathy of prematurity (ROP) is associated with increased retinal blood flow velocities. We investigated changes of central retinal arterial and venous blood flow after intravitreal administration of bevacizumab. SUBJECTS/METHODS Prospective observational study using serial ultrasound Doppler imaging in preterm infants with bevacizumab-treated ROP. Eyes were examined 1 [0-2] days before injection (median [interquartile range]), and at three time points after injection (1 [1-2] days, 6 [3-8] days, and 17 [9-28] days). Preterm infants with ROP stage 2 displaying spontaneous regression served as controls. RESULTS In 21 eyes of 12 infants with bevacizumab-treated ROP, peak arterial systolic velocity declined from 13.6 [11.0-16.3] cm/s prior to intravitreal bevacizumab to 11.2 [9.4-13.9] cm/s, 10.6 [9.2-13.3] cm/s and 9.3 [8.2-11.0] cm/s at discharge (p = .002). There was also a decline of the arterial velocity time integral (from 3.1 [2.3-3.9] cm to 2.9 [2.4-3.5], 2.7 [2.3-3.2] cm and 2.2 [2.0-2.7], p = .021) and mean velocity in the central retinal vein (from 4.5 [3.6-5.8] cm/s to 3.7 [2.6-4.1] cm/s, 3.5 [3.0-4.3] cm/s, and 3.2 [2.8-4.6] cm/s, p = .012). Arterial end-diastolic velocity and resistance index remained unchanged. Blood flow velocities in bevacizumab-treated eyes examined before injection were significantly higher than those measured in untreated eyes that ultimately showed spontaneous regression of ROP. Sequential examinations in these controls did not reveal any declines of retinal blood flow velocities. CONCLUSION Increased retinal arterial and venous blood flow velocities in infants with threshold ROP decline following intravitreal bevacizumab injection.

Abstract
A 65-year-old man presented with apparent bronchopneumonia. After treatment with antibiotics, he showed eosinophilia. Computed tomography (CT) imaging revealed bilateral consolidation, ground-glass opacities with nodular consolidations, and pleural effusion. Lung biopsy showed organising pneumonia with lymphoplasmacytic infiltration in the alveolar septa and in the thickened pleura and interlobular septa. All pulmonary abnormalities spontaneously went into remission within 12 months. At 73 years old, a follow-up CT scan revealed small nodules in both lungs and the review of the head CT scan showed thickening of the pituitary stalk in studying prolonged headache. Two years later, he visited the hospital complaining of severe oedema on the lower extremities with high serum immunoglobulin (Ig)G4 186 mg/dl. A whole-body CT scan showed retroperitoneal mass surrounding aortic bifurcation and compressing inferior vena cava, pituitary stalk thickening and gland swelling, and enlarged pulmonary nodules. Anterior pituitary stimulation tests showed central hypothyroidism, central hypogonadism, and adult growth hormone deficiency with partial primary hypoadrenocorticism. Retroperitoneal mass biopsy showed storiform fibrosis and obliterative phlebitis with marked lymphoplasmacytic infiltration with moderate IgG4-positivity. Immunostaining of the former lung specimen revealed dense interstitial infiltration of IgG4-positive cells. These findings indicated metachronous development of IgG4-related disease in lung, hypophysis, and retroperitoneum, according to the recent comprehensive diagnostic criteria of IgG4-related disease. Glucocorticoid therapy ameliorated oedema, on the other hand, unmasked partial diabetes insipidus at the initial dose of the treatment. Hypothyroidism and retroperitoneal mass regressed at 6 months of the treatment. This case warns us that long-term follow-up from prodromal to remission is necessary for the treatment of IgG4-related disease.

Abstract
Spontaneous remission of B-lymphoblastic leukemia (B-ALL) in the setting of viral and bacterial infections has been reported. Here, we present a case of B-ALL that showed a complete remission in the setting of group A streptococcal bacteremia. The patient was an 11-year-old boy who presented with a sore throat, right ear pain, and rhinorrhea. Prior to the diagnosis of B-ALL, he was diagnosed with streptococcal pharyngitis and received a single dose of dexamethasone and azithromycin. One day later, he was found to be pancytopenic and an immunophenotypically abnormal B-lymphoblastic population was detected comprising 0.6% and 16.8% of the peripheral blood and bone marrow cells, respectively. Though a diagnosis of B-ALL was highly suspected, blast percentage was <20% and the bone marrow showed relatively unremarkable trilineage hematopoiesis. On close monitoring, the suspected neoplastic population became undetectable by day 17 and the patient's complete blood count (CBC) completely normalized by day 46. On day 82, a peripheral blood smear demonstrated circulating blasts. Flow cytometry of a bone marrow aspirate revealed B-lymphoblastic leukemia accounting for 94% nucleated cells, consistent with the diagnosis of B-lymphoblastic leukemia. This case is of interest as less than 20 examples of spontaneous remission of B-ALL have been reported in the literature. As the case reported here relapsed and previously reported spontaneously remitting cases have uniformly relapsed, cases of B-ALL with spontaneous remission should be followed very closely for recurrence.

Abstract
Rubella retinopathy is usually a benign disorder with low impact on visual acuity. However, choroidal neovascularization can occur in these patients threatening their vision. We report the case of a 6-year-old girl with rubella retinopathy who developed a neovascular membrane and was successfully managed with observation. Decision to treat or observe in these patients must be carefully weighed, with both options being valid depending mainly on the location of the neovascular complex.

Abstract
Paediatric primary myelofibrosis (PMF) is exceedingly rare and distinct compared with adult PMF. It is characterised by peripheral blood cytopenias, leucoerythroblastosis, reticulin fibrosis, extramedullary haematopoiesis and hepatosplenomegaly. In the absence of laid down diagnostic criteria, the diagnosis is largely of exclusion. Though early haematological stem cell transplant (HSCT) remains the treatment of choice, spontaneous remission or remission with steroids and/or cytoreductive agents is described in around 20% of cases of paediatric PMF. Moreover, HSCT in paediatric PMF is associated with high mortality (30%-45%). Therefore, it may be prudent to consider a trial of steroids and/or cytoreductive agents in all transfusion-dependent paediatric PMF while considering HSCT and ongoing bone marrow donor search. We describe one such infant with PMF who had complete remission of clinical and haematological parameters with a combination therapy of steroids and hydroxyurea.

Abstract
BACKGROUND New-onset diabetes in youth encompasses type 1 diabetes, type 2 diabetes, monogenic diabetes, and rarer subtypes like Type B insulin resistance syndrome and ketosis-prone atypical diabetes in African populations. Some cases defy classification, posing management challenges. Here, we present a case of a unique, reversible diabetes subtype. CASE PRESENTATION We describe an adolescent African girl recently diagnosed with systemic lupus erythematosus. At age 15, she presented with ketoacidosis, HbA1c of 108.7 mmol/mol (12.1%), and positive anti-insulin antibodies. Initially diagnosed with type 1 diabetes, insulin was prescribed. Due to the presence of obesity and signs of insulin resistance, we added metformin. Concurrently, she received treatment for lupus with hydroxychloroquine, mycophenolate mofetil, and prednisone. After discharge, she stopped insulin due to cultural beliefs. Five months later, her glycemia and HbA1c normalized (37 mmol/mol or 5.5%) without insulin, despite corticosteroid therapy and weight gain. Autoantibodies normalized, and lupus activity decreased. Genetic testing for monogenic diabetes was negative, and the type 1 genetic risk score was exceptionally low. CONCLUSIONS We present a complex, reversible diabetes subtype. Features suggest an autoimmune origin, possibly influenced by overlapping HLA risk haplotypes with lupus. Lupus treatment or immunomodulation may have impacted diabetes remission. Ancestry-tailored genetic risk scores are currently designed to improve diagnostic accuracy.

Abstract
We present a 73-year-old man with a history of lung adenocarcinoma and multiple metastases. He was treated with chemotherapy, including pembrolizumab, but treatment was interrupted due to concurrent drug-induced lung injury. Seventeen weeks after the last dose of pembrolizumab, he developed encephalitis, presenting with a disturbance of consciousness and right hemiplegia. However, his symptoms gradually improved spontaneously and disappeared three weeks after their onset. Late-onset encephalitis after the administration of immune checkpoint inhibitors is rare. In addition, this is the first report of a case in which severe encephalitis recovered spontaneously without leaving sequelae.

Abstract
Anterior cruciate ligament (ACL) injuries have a very low healing capacity but have recently been shown to heal spontaneously with conservative treatment. This study examined the mechanism of spontaneous ACL healing by focusing on the intra-articular tissues of the knee joint. Skeletally mature Wistar rats (n = 70) were randomly assigned to two groups: the controlled abnormal movement (CAM) and anterior cruciate ligament transection (ACLT) groups. The ACL was completely transected at the mid-portion in both groups. Only the CAM group underwent extra-articular braking to control for abnormal tibial translation. The animals were allowed full cage activity until sacrifice for histological, and molecular biology analyses. The results showed that the behavior of the stump after ACL injury differed between models 12 h after injury. The femoral stump in the ACLT group retreated posteriorly and upwardly. Macrophage polarity analysis revealed that the stump immune response in the CAM group was more activated than that in the ACLT group 6 h after injury. Microarray analysis of the ACL parenchyma and infrapatellar fat pads suggested the involvement of nuclear factor kappa B (NF-κB) signaling. Real-time polymerase chain reaction (PCR) analysis showed that NF-κB gene expression in the infrapatellar fat pad was significantly increased in the CAM group than in the ACLT group. However, there was no difference in the gene expression levels in the ACL parenchyma between models. In conclusion, the healing response of the ACL was activated within 12 h of injury, resulting in differences in the healing response between the models. It has been suggested that infrapatellar fat pads are involved in the healing process and that angiogenesis and antiapoptotic effects through NF-κB signaling may contribute to this mechanism.

Abstract
Eclipsed mitral regurgitation is a relatively new disease concept reported in recent years, of which is not fully elucidated. A 73-year-old female had repeated episodes of heart failure of unknown cause. During cardiac catheterization and echocardiography performed, mitral regurgitation suddenly worsened and improved in a few minutes. The patient was diagnosed as having eclipsed mitral regurgitation with multiple episodes of acute exacerbation and remission. Although mechanism of exacerbation remains unclear, morphological change of the left ventricle is likely to be a major cause, and mitral valve replacement seems better than plasty for prevention of recurrent heart failure. The patient underwent valve replacement using a bioprothesis and was discharged from the hospital on her own 24 days after surgery. Six months after the operation, she has been doing well without recurrence of heart failure.

Abstract
Gout is a common inflammatory arthritis that has been increasing in both prevalence and incidence. Consequently, management of refractory and chronic gout has been gaining attention. Onset of gout is related to the deposition of monosodium urate crystals under hyperuricaemia. Interestingly, acute gout attacks often resolve spontaneously within 7-10 days, and many studies have confirmed the notion that gout flares can be self-relieved. However, the underlying mechanism for spontaneous remission of gout requires further elucidation. In this article, we summarise the roles and mechanisms related to spontaneous remission of gout, which are essential for understanding its pathogenesis and developing potential targeted therapies.

Abstract
BACKGROUND A few case reports have described patients with myelin oligodendrocyte glycoprotein antibody (MOG-Ab)-associated demyelinating syndrome who presented with symptoms of aseptic meningitis. All such patients required immunotherapy. We report a patient with MOG-Ab-associated disorder (MOGAD) who presented with symptoms of aseptic meningitis and improved without treatment. CASE A 13-year-old girl presented with fever, headache, decreased appetite, and neck stiffness. Cerebrospinal fluid (CSF) analysis revealed pleocytosis and magnetic resonance imaging (MRI) showed leptomeningeal enhancement. The patient was diagnosed with aseptic meningitis at admission. However, there were no signs of recovery 4 days after admission (i.e., 8 days after disease onset). Therefore, we performed extensive investigations to identify the cause of the underlying infection and inflammation. On day 14 after admission, the serum MOG-Ab test performed at admission came back positive (1:128) and she was diagnosed with MOGAD. She was discharged on day 18 after admission, because her symptoms, CSF pleocytosis, and MRI findings had improved. About 6 weeks after discharge, MRI revealed hyperintensity without gadolinium enhancement. However, her serum MOG-Ab test was negative. We did follow-ups for 11 months but found no new neurological symptoms. DISCUSSION AND CONCLUSION To the best of our knowledge, this is the first ever report of a pediatric patient with MOGAD experiencing spontaneous remission with no demyelinating symptoms during an extended follow-up period.

Abstract
BACKGROUND Angioimmunoblastic T-cell lymphoma is an uncommon subtype of peripheral T-cell lymphoma in children with fewer than 20 cases reported in literature. CASE PRESENTATION A 3-year-old Omani boy was diagnosed with ataxia-talengectasia presenting with fever and generalized lymphadenopathy. His biopsy revealed atypical lymphocytic infiltrate consistent with the diagnosis of angioimmunoblastic T-cell lymphoma. Within 3 weeks from the initial presentation and without any neoadjuvant therapy, he showed complete recovery of symptoms with absence of fever and regression of all previously affected lymph nodes. He has remained in remission ever since. CONCLUSION This is the first report of spontaneous improvement of angioimmunoblastic T-cell lymphoma in a patient with ataxia-telangiectasia who was 3 years old at presentation. Owing to the paucity of similar cases, this report adds valuable diagnostic, therapeutic, and monitoring data.

Abstract
Membranous nephropathy (MN) is an immune-complex glomerulonephritis and is one of the most common causes of nephrotic syndrome in adults and is also one of the autoimmune kidney diseases with the highest rate of spontaneous remission. The most common autoantigen (> 70% of cases) is directed against the phospholipase A2 receptor (PLA2-R) and, with its detection and clinical course, allows for excellent diagnostics as well as optimal therapy monitoring. Other autoantigens are constantly being published and will enable an autoantigen-based diagnostic and therapeutic algorithm for MN in the future. In the absence of spontaneous remission, a specific B‑cell-directed therapy, especially with rituximab, is the initial therapy of choice. Calcineurininhibitors or cyclophosphamide should only be used if they are carefully indicated in the respective clinical context and if there are serious clinical consequences both from the nephrotic syndrome and from loss of kidney function. Since immune complexes within the kidney often require a long time to be degraded, proteinuria response can follow the immunological remission after many months. The therapy of MN represents the favorable case of a precision medicine-based therapy in nephrology, whereby new therapeutic B‑cell antibodies for the rare but difficult forms of MN will find their way into clinical routine in the not-too-distant future.

Abstract
INTRODUCTION Eosinophilic granuloma (EG) is the most common form of Langerhans cell histiocytosis, presenting as a single osteolytic lesion of the calvarium. Its diagnosis is based on typical clinical and radiological features. While surgical resection has been the standard treatment for EG, growing evidence favors watchful waiting, as unifocal calvarial lesions appear to frequently undergo spontaneous remission. However, histopathological confirmations of this hypothesis are still very limited. METHODS Methods. Here, we report a case of EG with typical clinical and radiological features which, due to intervening circumstances, was resected in a delayed fashion. Moreover, we perform a systematic review of the literature on conservative management of EG. RESULTS In our case, histological examination showed ongoing bone regeneration with no traces of the disease. Through our literature review, we found 47 cases of calvarial EG managed with watchful waiting. No active intervention was required in 43 cases (91%). Four patients (9%) received surgery or chemotherapy due to the persistence/progression of symptoms or family request. Three reports other than ours documented spontaneous disease remission in surgically resected EG upon histopathological examination. CONCLUSION Our report provides further evidence that watchful waiting can be a reasonable option in the management of single calvarial EG.

Abstract
RATIONALE Acute myeloid leukemia (AML)/myeloid sarcoma (MS) is risk-stratified based on cytogenetics. Although most congenital AML/MS have a dismal prognosis, certain genetic variants such as t (8, 16) [KAT6A::cAMP response element-binding protein (CREB) - binding protein fusion] and more recently t (8, 22) [KAT6A::EP300 fusion] have shown spontaneous remissions. KAT6A located on chromosome 8p11 encodes KAT6A protein, a histone/lysine acetyltransferase enzyme. Numerous partner genes associated with KAT6A include cAMP response element-binding protein (CREB) - binding protein (16p13), EP300 (22q13), LEUTX (9q13), NCOA2, NCOA3, and ASXL2. PATIENT CONCERNS In this article, we describe an otherwise healthy infant who presented with skin nodules on the face and scalp without any systemic or CNS involvement. A biopsy of the cutaneous lesion was consistent with congenital MS. DIAGNOSES Through molecular testing, we found that our patient had the KAT6A::EP300 mutation. This is one of the rare recurrent cytogenetic abnormalities that are linked to congenital AML. INTERVENTION Our patient underwent spontaneous remission with watchful waiting. OUTCOME Our patient has remained in spontaneous remission for 24 months. LESSONS Even though the KAT6A::EP300 mutation in adults is a poor prognostic marker, a similar mutation in congenital AML has a higher likelihood of spontaneous remission. Hence, conservative management might be an initial management strategy for clinically stable patients.

Abstract
One of the very uncommon clinical conditions is the spontaneous remission of tumors, with scarce reports around the world in various types of tumors. Spontaneous remission of hepatocellular carcinoma (HCC) is extremely rare, but it is well documented with a still unclear underlying mechanism. In this case report, we present one of those exceptional incidents of HCC regression with a trial to tackle possible explanations. Our case, which has a history of successfully treated hepatitis C virus, presented with a large infiltrative right lobar mass invading the main portal vein, with markedly elevated alpha fetoprotein (AFP). According to the applied diagnostic and treatment guidelines, the patient was scheduled for conservative management. Although he did not receive any specific treatments for his condition, the mass regressed in size with recanalization of the portal vein and normalization of AFP after 6 months of follow-up and keep the same for the following 3 years. The mechanisms by which spontaneous regression of HCC can occur are still unknown and should be furtherly investigated better to understand the behavior of such aggressive neoplastic disease.

Abstract
AIM The earlier the onset of proteinuria, the higher the incidence of genetic forms. Therefore, we aimed to analyse the spectrum of monogenic proteinuria in Egyptian children presenting at age <2 years. METHODS The results of 27-gene panel or whole-exome sequencing were correlated with phenotype and treatment outcomes in 54 patients from 45 families. RESULTS Disease-causing variants were identified in 29/45 (64.4%) families. Mutations often occurred in three podocytopathy genes: NPHS1, NPHS2 and PLCE1 (19 families). Some showed extrarenal manifestations. Additionally, mutations were detected in 10 other genes, including novel variants of OSGEP, SGPL1 and SYNPO2. COL4A variants phenocopied isolated steroid-resistant nephrotic syndrome (2/29 families, 6.9%). NPHS2 M1L was the single most common genetic finding beyond the age of 3 months (4/18 families, 22.2%). Biopsy results did not correlate with genotypes (n = 30). On renin-angiotensin-aldosterone system antagonists alone, partial and complete remission occurred in 3/24 (12.5%) patients with monogenic proteinuria each, whereas 6.3% (1/16) achieved complete remission on immunosuppression. CONCLUSION Genotyping is mandatory to avoid biopsies and immunosuppression when proteinuria presents at age <2 years. Even with such a presentation, COL4A genes should be included. NPHS2 M1L was prevalent in Egyptian children (4 months-2 years) with proteinuria, demonstrating precision diagnostic utility.

Abstract
BACKGROUND The extent to which biomarkers of asthma activity persist in spontaneous asthma remission and whether such markers are associated with future respiratory outcomes remained unclear. We investigated the association between sub-clinical inflammation in adults with spontaneous asthma remission and future asthma relapse and lung function decline. METHODS The Tasmanian Longitudinal Health Study is a population-based cohort (n = 8583). Biomarkers of systemic inflammation were measured on participants at age 45, and latent profile analysis was used to identify cytokine profiles. Bronchial hyperresponsiveness (BHR) and nitric oxide products in exhaled breath condensate (EBC NOx) were measured at age 50. Participants with spontaneous asthma remission at ages 45 (n = 466) and 50 (n = 318) were re-evaluated at age 53, and associations between baseline inflammatory biomarkers and subsequent asthma relapse and lung function decline were assessed. RESULTS We identified three cytokine profiles in adults with spontaneous asthma remission: average (34%), Th2-high (42%) and Th2-low (24%). Compared to the average profile, a Th2-high profile was associated with accelerated decline in post-BD FEV1 /FVC (MD -0.18% predicted per-year; 95% CI -0.33, -0.02), while a Th2-low profile was associated with accelerated decline in both post-BD FEV1 (-0.41%; -0.75, -0.06) and post-BD FVC (-0.31%; -0.62, 0.01). BHR and high TNF-α during spontaneous remission were associated with an increased risk of asthma relapse. In contrast, we found no evidence of association between EBC NOx and either asthma relapse or lung function decline. CONCLUSION BHR and serum inflammatory cytokines have prognostic value in adults with spontaneous asthma remission. At-risk individuals with BHR, Th2-high or Th2-low cytokine profiles may benefit from closer monitoring and on-going follow-up.
