Abstract
Antiphospholipid syndrome (APS) is an acquired thrombophilic disorder related to the presence of antiphospholipid antibodies (LAC, anticardiolipin, anti Beta2-glycoprotein) known to cause venous and arterial thrombosis and recurrent pregnancy loss. Skin disorder is a frequent finding usually due to vascular thrombosis involving the dermal layer and can be either localized or widespread causing necrosis and ulceration of the skin, without histological evidence of vasculitis. We present a case of a woman with APS with both arterial and venous thrombotic involvement associated with an atypical dermatological manifestation histologically consistent with a pauci-inflammatory intermediate-deep dermal arteriolar platelet-mediated thrombosis that appeared despite anticoagulation with warfarin and responding to the addition of antiplatelet therapy.

Abstract
Background Enteric-type adenocarcinoma of the lung (lung-ETAC) is a rare form of lung cancer with histologic similarities to colorectal cancer, with aggressive behavior and unfavorable prognosis. Case Presentation An 81-year-old man presented with discolored skin lesions on the chest and abdomen. After comprehensive evaluation, including skin biopsy and molecular profiling, the patient was diagnosed with having lung-ETAC with a BRAF p.V600E mutation. Treatment with dabrafenib and trametinib initially resulted in positive results, with improvement in skin lesions and overall clinical condition. Nevertheless, approximately 6 months after, the disease had progression with new skin lesions reappearing. Conclusions We reported a unique case of a patient with BRAF p.V600E-mutant lung-ETAC with metastatic skin lesions achieving complete cutaneous response after targeted treatment with dabrafenib and trametinib, highlighting the potential for targeted therapy in patients with lung-ETAC harboring a BRAF p.V600E mutation.

Abstract
A 71-year-old woman presented with a persistent, intensely pruritic cutaneous eruption localized on the palmoplantar regions, lips and palate. The histological findings allowed to make the diagnosis of recurrent cutaneous eosinophilic vasculitis, a very rare cutaneous vasculitis characterized clinically by multiple erythematous or purpuric erythematous papules or plaques or angioedema with a relapsing course in the absence of systemic involvement and histologically by a necrotizing vasculitis of the dermal small vessels with a dominant eosinophilic infiltration. The patient was treated with oral methylprednisolone and pentoxifylline which led to a rapid resolution of the cutaneous lesions.

Abstract
Pseudo-Pelger-Huët anomaly is a condition in which almost all the granulocytes are hyposegmented and/or hypogranulated. It is typically recognized in peripheral blood smears and represents a marker of several disorders, such as myeloproliferative diseases and myelodysplasia. The occurrence of the pseudo-Pelger-Huët anomaly in the cutaneous infiltrate of pyoderma gangrenosum is very rare. We describe the case of a 70-year-old man with idiopathic myelofibrosis who developed pyoderma gangrenosum. Histological examination showed an infiltrate consisting of granulocytic elements with features of dysmaturity and segmentation anomalies (hypo- and hypersegmented forms), suggestive of pseudo-Pelger-Huët anomaly. Methylprednisolone treatment resulted in progressive improvement of pyoderma gangrenosum.

Abstract
Several cutaneous diseases can present with annular lesions, making a distinction by physical appearance alone challenging. They can be distinguished into infectious and non-infectious, and common and uncommon annular dermatoses. Common non-infectious diseases include granuloma annulare, urticaria, and subacute lupus erythematosus. In addition, there are rare non-infectious non-neoplastic annular dermatoses whose nosographic attribution is established, including annually recurring erythema annulare centrifugum (EAC) and annular erythema in Sjögren syndrome and others whose nosographic positioning is still debated. They are neutrophilic figurate erythema, palpable migratory arciform erythema, eosinophilic annular erythema, and annular lichenoid dermatitis of youth. Their etiopathogenesis is largely unknown, although immune-mediated mechanisms are likely involved. It is difficult to establish if they are variants of reaction patterns or separate clinic-pathological entities. In fact, EAC and annually recurring EAC may represent different aspects of the same disease. Palpable migratory arciform erythema is hardly distinguishable from EAC deep type, Jessner-Kanof disease, and lupus tumidus. Neutrophilic figurate erythema and eosinophilic figurate erythema are clinically very similar and differing only in the relative proportion of eosinophils and neutrophils.

Abstract
A child who comes to our attention for the appearance of erythematous, scaly lesions localized to the upper and lower limbs for 2 months. Histological features suggested ichthyosiform disease and concomitant mutations in the SPINK5 and FLG2 genes confirmed Netherton syndrome with severe atopic manifestations.

Abstract
Pilomatricoma is a relatively common benign cutaneous adnexal tumor and a well-recognized entity, while its pigmented variant is far less common and less reported. Its estimated frequency ranges from 11 to 24%, according to a limited number of published case series. This article describes the case of a 42-year-old man presenting a firm subcutaneous nodule of the periareolar region. Histopathologic examination revealed a cystic lesion composed of matrical and supramatrical cells accompanied by a foreign body granulomatous cell reaction. Interestingly, a hyperpigmented area with numerous hyperplastic melanocytes and few mitoses was detectable. In order to assess the cell lineage of the mitotically active component in the hyperpigmented area, double immunohistochemistry with Ki67/Mart1 and p63/SOX10 was performed. Pigmented pilomatricoma is an underrecognized, underreported variant, and double immunohistochemistry stain is an effective tool in providing the correct interpretation of the proliferative activity in the different cellular populations.

Abstract
We report an 11-year-old girl who presented with white papules on the dorsal and palmar region of the hands bilaterally. The parents reported that the lesions had appeared four months before and some had resolved spontaneously. The girl was suffering from celiac disease, Down syndrome, and alopecia areata treated with topical corticosteroids. At the first visit, the girl presented with alopecia areata, corticosteroid acne, and a dozen white papules located on the hands. On dermoscopy, a whitish structureless area was seen. Histological examination showed the presence of calcium deposits without tissue damage, thus confirming the diagnosis of milia-like idiopathic calcinosis cutis. At 6-month follow up, the lesions had completely disappeared. Milia-like idiopathic calcinosis cutis is a benign cutaneous disorder consisting of calcium deposits in an apparently undamaged dermis and is typically associated with Down syndrome. Up to a quarter of patients have coexisting syringomas. The milia-like papules tend to self-resolve as patients reach adulthood, so a wait-and-see approach is recommended.

Abstract
Annually recurring erythema annulare centrifugum (AR-EAC) is a rare variant, characterized by typical annular plaques recurring in the same period of the year. We describe 5 new cases and present a review of the literature. Patients were 3 females and 2 males with an age range of 25–55 years. Multiple annular plaques were located at the thighs in 4 patients and the neck in one patient. In 1 patient, a single lesion was present. Plaques were recurring in summer in 3 cases; in 1 case, in spring; and another patient, in winter since 3–4 years. Lesions were self-healing in few days or weeks. Histologically, the epidermis presented mild acanthosis with patchy spongiosis, slight parakeratosis, and mild exocytosis. There was a perivascular lympho-histiocytic infiltrate of variable intensity in the superficial dermis, with occasional eosinophils. In 1 case, the inflammatory infiltrate reached the deep dermis. Mucin deposition was absent. Phenotyping studies in 1 case revealed a predominance of T cells, with a small B-cell component. Moreover, a moderate number of CD123<sup>+</sup> plasmacytoid dendritic cells and CD1a<sup>+</sup> dendritic cells were noted. Fourteen cases of AR-EAC have been published previously. Collectively, patients' age ranged from 16 to 83 years, with a mean age of 47 years and a disease duration of 1–30 years. Lesions affected more frequently extremities and recurred most commonly in summer. Patients were all in good general health. Topical corticosteroids were the mainstay of treatment. AR-EAC is a benign disorder, the nature of which remains enigmatic.

Abstract
The expression of programmed death-ligand 1 (PD-L1) is an established prerequisite for the administration of checkpoint inhibitor therapy and is of prognostic value in several cancer types. Data concerning the potential effect of PD-L1 on the prognosis of thyroid carcinoma are limited. Therefore, this study aimed to provide a systematic review of the published data on this topic. The literature was reviewed to gather and quantify evidence on the prognostic role of PD-L1 in follicular epithelial derived thyroid carcinomas and determine its association with clinicopathological parameters. A meta-analysis was performed using the DerSimonian-Laird random-effects model. The quality of studies was evaluated with the Newcastle-Ottawa Scale and a modified GRADE approach used to rate the quality of evidence. Out of 445 papers, 18 were included and 15 provided adequate data for meta-analysis. The quality of evidence ranged from low to high. PD-L1 expression was significantly associated with a reduced disease-free survival (DFS) (RR 1.63, CI 1.04-2.56, p = 0.03, I2 68%, τ2 0.19 and HR 1.90, CI 1.33-2.70, p< 0.001, I2 0%, τ2 0.00); however, no association was found with the overall survival (OS). Furthermore, a significant association was found with respect to underlying chronic lymphocytic thyroiditis and BRAFV600E mutation status in papillary thyroid carcinomas. In the subgroup analysis, the association of PD-L1 and DFS remained strong in papillary thyroid carcinoma when compared with dedifferentiated thyroid carcinomas (anaplastic and poorly differentiated thyroid carcinomas) that failed to demonstrate a significant association with respect to PD-L1. These findings underscore the role of PD-L1 immunohistochemistry as a potential prognostic biomarker of disease recurrence in patients with papillary thyroid carcinoma.

Abstract
Hyaluronic acid injection to rejuvenate or to correct defects is a very common practice in aesthetic medicine. Although it is considered highly safe because of biocompatibility and biodegradability, adverse reactions can occur. Herein, we report a patient with foreign body granuloma formation that presented as multiple subcutaneous nodules on both arms, following injections of hyaluronic acid performed about six years earlier. Our case is unique with respect to timing and area of granuloma appearance.

Abstract
Sickle cell disease is an autosomal recessive genetic red cell disorder with a worldwide distribution. Growing evidence suggests a possible involvement of complement activation in the severity of clinical complications of sickle cell disease. In this study we found activation of the alternative complement pathway with microvascular deposition of C5b-9 on skin biopsies from patients with sickle cell disease. There was also deposition of C3b on sickle red cell membranes, which is promoted locally by the exposure of phosphatidylserine. In addition, we showed for the first time a peculiar “stop-and-go” motion of sickle cell red blood cells on tumor factor-α–activated vascular endothelial surfaces. Using the C3b/iC3b binding plasma protein factor Has an inhibitor of C3b cell-cell interactions, we found that factor H and its domains 19-20 prevent the adhesion of sickle red cells to the endothelium, normalizing speed transition times of red cells. We documented that factor H acts by preventing the adhesion of sickle red cells to P-selectin and/or the Mac-1 receptor (CD11b/CD18), supporting the activation of the alternative pathway of complement as an additional mechanism in the pathogenesis of acute sickle cell related vaso-occlusive crises. Our data provide a rationale for further investigation of the potential contribution of factor H and other modulators of the alternative complement pathway with potential implications for the treatment of sickle cell disease.

Abstract
Introduction: Follicular-derived differentiated thyroid carcinoma (DTC) is the most common endocrine and epithelial malignancy in children. The differences in the clinical and pathological features of pediatric vs. adult DTC could relate to a different genetic profile. Few studies are currently available in this issue, however, and most of them involved a limited number of patients and focused mainly on radiation-exposed populations. Materials and Methods: We considered 59 pediatric patients who underwent surgery for DTC between 2000 and 2017. RET/PTC rearrangement was investigated with fluorescent in situ hybridization and real-time polymerase chain reaction. Sequencing was used to analyze mutations in the BRAF, NRAS, PTEN, PIK3CA genes, and the TERT promoter. The pediatric patients' clinical and molecular features were compared with those of 178 adult patients. Results: In our pediatric sample, male gender and age <15 years coincided with more extensive disease and more frequent lymph node and distant metastases. Compared with adults, the pediatric patients were more likely to have lymph node and distant metastasis, and to need second treatments (p < 0.01). In all, 44% of the pediatric patients were found to carry molecular alterations. RET/PTC rearrangement was confirmed as the most frequent genetic alteration in childhood DTC (24.6%) and correlated with aggressive features. BRAFV600E was only identified in 16% of the pediatric DTCs, while NRASQ61R, NRASQ61K, and TERTC250T mutations were very rare. Conclusions: Pediatric DTC is more aggressive at diagnosis and more likely to recur than its adult counterpart. Unlike the adult disease, point mutations have no key genetic role.

Abstract
Background Extramedullary plasma cell dyscrasias are rare. Case report We report a case of a 56-year-old male Caucasian hemodialysis patient with cutaneous plasmacytoma. The diagnosis was made a few months after surgical removal of his renal graft due to chronic rejection. Investigations for the presence of an associated myeloma were negative. He underwent local radiotherapy with complete resolution of the skin lesion. Conclusions Nephrologists should be aware that the frequency of post-transplant lymphoproliferative disorders is increasing in the dialysis population, especially in those previously or currently treated with immunosuppressive drugs.

Abstract
Background: Primary cutaneous CD4+ small/medium T-cell lymphoproliferative disorder (CD4+ PCSM-LPD) is defined by a predominance of small- to medium-sized CD4+ pleomorphic T cells and a favorable clinical course. Objective: We performed a retrospective analysis of 6 patients with CD4+ PCSM-LPD and reviewed the literature to address questions about its diagnosis, treatment, and prognosis. Methods: Patients were 3 men and 3 women with a median age of 50 years. All patients presented with a single erythematous nodule, localised on the head in 4 patients and the upper trunk in 2 cases. No patients showed extracutaneous disease at any evaluation. Histopathologic features were characterised by nodular, diffuse, or, in 1 case, a superficial dense infiltrate of small/medium-sized pleomorphic CD4+/PD1+ T lymphocytes. T-cell receptor clonality was demonstrated in 5 cases. Treatment was surgical excision in 5 cases and radiotherapy in 1 case. Results: All patients achieved complete resolution without relapses, during a median follow-up of 3 years. A review of the literature confirmed that CD4+ PCSM-LPD presents predominantly with a solitary nodular lesion on the face, neck, or upper trunk in adult patients. Surgical excision is the preferred treatment. Spontaneous resolution after biopsy may occur. Conclusions: CD4+ PCSM-LPD is a rare disorder with a favorable course.

Abstract
In immunocompromised patients, Aspergillus infections are important causes of morbidity and mortality. We describe a patient with cryoglobulinemic vasculitis who developed disseminated invasive aspergillosis with thyrotoxicosis caused by Aspergillus fumigatus. The diagnosis was based upon radiological, microbiological and pathological findings. The patient was treated successfully with voriconazole and caspofungin treatment followed by total thyroidectomy. We provide an overview of published reports on Aspergillus thyroiditis with an emphasis on therapeutic approaches.

Abstract
Advanced medullary thyroid cancers (MTCs) are now being treated with drugs that inhibit receptor tyrosine kinases, many of which involved in angiogenesis. Response rates vary widely, and toxic effects are common, so treatment should be reserved for MTCs likely to be responsive to these drugs. RET mutations are common in MTCs, but it is unclear how they influence the microvascularization of these tumors. We examined 45 MTCs with germ-line or somatic RET mutations (RETmut group) and 34 with wild-type RET (RETwt). Taqman Low-Density Arrays were used to assess proangiogenic gene expression. Immunohistochemistry was used to assess intratumoral, peritumoral and nontumoral expression levels of VEGFR1, R2, R3, PDGFRa, PDGFB and NOTCH3. We also assessed microvessel density (MVD) and lymphatic vessel density (LVD) based on CD31-positive and podoplanin-positive vessel counts, respectively, and vascular pericyte density based on staining for a-smooth muscle actin (a-SMA), a pericyte marker. Compared with RETwt tumors, RETmut tumors exhibited upregulated expression of proangiogenic genes (mRNA and protein), especially VEGFR1, PDGFB and NOTCH3. MVDs and LVDs were similar in the two groups. However, microvessels in RETmut tumors were more likely to be a-SMA positive, indicating enhanced coverage by pericytes, which play key roles in vessel sprouting, maturation and stabilization. These data suggest that angiogenesis in RETmut MTCs may be more intense and complete than that found in RETwt tumors, a feature that might increase their susceptibility to antiangiogenic therapy. Given their increased vascular pericyte density, RETmut MTCs might also benefit from combined or preliminary treatment with PDGF inhibitors.

Abstract
OBJECTIVE Chromosomal rearrangements of the RET proto-oncogene is one of the most common molecular events in papillary thyroid carcinoma (PTC). However, their pathogenic role and clinical significance are still debated. This study aimed to investigate the prevalence of RET/PTC rearrangement in a cohort of BRAF WT PTCs by fluorescence in situ hybridization (FISH) and to search a reliable cut-off level in order to distinguish clonal or non-clonal RET changes. DESIGN Forty BRAF WT PTCs were analyzed by FISH for RET rearrangements. As controls, six BRAFV600E mutated PTCs, 13 follicular adenomas (FA), and ten normal thyroid parenchyma were also analyzed. METHODS We performed FISH analysis on formalin-fixed, paraffin-embedded tissue using a commercially available RET break-apart probe. A cut-off level equivalent to 10.2% of aberrant cells was accepted as significant. To validate FISH results, we analyzed the study cohort by qRT-PCR. RESULTS Split RET signals above the cut-off level were observed in 25% (10/40) of PTCs, harboring a percentage of positive cells ranging from 12 to 50%, and in one spontaneous FA (1/13, 7.7%). Overall, the data obtained by FISH matched well with qRT-PCR results. Challenging findings were observed in five cases showing a frequency of rearrangement very close to the cut-off. CONCLUSIONS FISH approach represents a powerful tool to estimate the ratio between broken and non-broken RET tumor cells. Establishing a precise FISH cut-off may be useful in the interpretation of the presence of RET rearrangement, primarily when this strategy is used for cytological evaluation or for targeted therapy.

Abstract
Objective The role of complement system in the pathogenesis of systemic sclerosis (SSc) has been debated during the last decade but an evident implication in this disease has never been found. We carried out an explorative study on SSc patients to evaluate the expression of soluble and local C5b-9 complement complex and its relation with a complement regulator, the Membrane Cofactor Protein (MCP, CD46) on skin vascular bed as target distinctive of SSc disease. We also analyzed two polymorphic variants in the complement activation gene cluster involving the MCP region. Methods C5b-9 plasma levels of SSc patients and healthy subjects were analyzed by ELISA assay. Archival skin biopsies of SSc patients and controls were subjected to immunofluorescence analysis to detect C5b-9 and MCP on vascular endothelial cells. The expression of MCP was validated by immunoblot analysis with specific antibody. Polymorphic variants in the MCP gene promoter were tested by a quantitative PCR technique-based allelic discrimination method. Results Even though circulating levels of C5b-9 did not differ between SSc and controls, C5b-9 deposition was detected in skin biopsies of SSc patients but not in healthy subjects. MCP was significantly lower in skin vessels of SSc patients than in healthy controls and was associated with the over-expression of two polymorphic variants in the MCP gene promoter, which has been related to more aggressive phenotypes in other immune-mediated diseases. Conclusions Our results firsty document the local complement activation with an abnormal expression of MCP in skin vessels of SSc patients, suggesting that a subset of SSc patients might be exposed to more severe organ complications and clinical evolution due to abnormal local complement activation.

Abstract
Pyoderma gangrenosum (PG) is a rare neutrophilic dermatosis of unknown etiology with distinct clinical manifestations, frequently associated with systemic diseases. Four clinical and histological variants have been described: ulcerative, pustular, bullous, and vegetative. We report on a case of superficial granulomatous pyoderma (SGP), a vegetative form of PG, in a 40-year-old woman. Physical examination revealed an erythematous crusted plaque, measuring 2 cm in diameter, located on her left hip, which had appeared 18 months ago. Dermoscopy showed lack of pigment network, large gray-blue ovoid nests, irregular peripheral vessels, and ulceration. Laboratory examinations were normal; smears and cultures for bacteria and fungi were negative. Clinical and dermatoscopical presentation suggested basal cell carcinoma. The lesion was completely removed: histological examination showed pseudoepitheliomatous hyperplasia with intraepidermal micro-abscesses and prominent dermal inflammatory infiltrate with typical three-layered granulomas consisting of palisading suppurative granulomas surrounded by plasma cells and eosinophils (diffuse neutrophilic infiltration with dermal inflammatory infiltrates consisting of epithelioid histiocytes, lymphocytes, and multinucleated giant cells). Based on clinical and histological correlation, the diagnosis of SPG was definitively established.

Abstract
Coma-induced blisters is a rare condition associated with prolonged impairment of conscious level, which is relatively well-known in adults following overdose with barbiturates. However, it has been very rarely described in children. A case of coma-bullae occurring in an 11-year-old child with meningoencephalitis is herein reported. The bullous lesions occurred on the limbs and trunks, and evolved into necrotic ulcers in a few days. No correlation with any drug overdosage was found. A skin biopsy revealed epidermal and eccrine sweat gland necrosis with abundant neutrophils, and thrombosis of the vessels in the lower dermis. A comprehensive review of the literature showed that only 5 cases of coma-bullae in children have been published so far. Coma blistering resolves spontaneously within days or weeks. Diagnosis of coma-bullae may require careful clinical-pathologic correlation to exclude other blistering diseases in children.

Abstract
INTRODUCTION Human leukocyte antigen-G (HLA-G), a nonclassical major histocompatibility complex class I antigen, plays a pivotal role in immune tolerance and a paradoxical role in cancers. AIMS Our aims were to evaluate plasma soluble HLA-G (sHLA-G) concentrations and the 14-bp insertion/deletion polymorphism of the HLA-G gene in patients with papillary thyroid carcinoma (PTC) or Hashimoto's thyroiditis (HT) and to assess the possible association of these parameters with PTC aggressiveness. METHODS Samples for the analysis of sHLA-G and +14/-14-bp HLA-G polymorphism were obtained from 121 patients with HT and 183 with PTC; 245 gender- and age-matched healthy subjects served as controls. PTC histopathological aggressiveness was defined according to the last American Thyroid Association guidelines. RESULTS Positive serum antithyroid antibody titers were observed in 22% of PTC patients and lymphocyte infiltration of thyroid parenchyma at histological examination in 21%, whereas both circulating and histological autoimmunity was detectable in 12% of PTC patients. No differences in the +14/-14-bp polymorphism frequencies were observed between the study groups. The prevalence of detectable sHLA-G was lower in healthy controls (52%) as compared with both HT (57%) and PTC (62%) patients. By stratifying the study groups according to sHLA-G level of positive subjects, significantly higher plasma sHLA-G values in PTC (42.9 ± 3.3 ng/ml; P = 0.002) and HT patients (49.1 ± 2.6 ng/ml; P < 0.002) as compared with healthy controls (8.5 ± 1.8 ng/ml) were obtained. Moreover, PTC patients with detectable plasma sHLA-G levels showed a higher aggressive behavior (P < 0.04) than those without. CONCLUSIONS Although confirming the frequent association between PTC and chronic autoimmune thyroiditis, these data suggest that elevated circulating sHLA-G levels, besides an important signal of alterations of immune homeostasis, may be considered a potential, novel marker of PTC histopathological aggressiveness at diagnosis. Additional studies are needed to confirm the actual role and clinical relevance of the HLA-G complex in PTC development and progression.
