Abstract
Idiopathic granulomatous mastitis (IGM) is a rare, benign inflammatory disorder of the breast that is often underrecognized. The exact etiology and pathophysiology are unknown, but milk stasis is felt to play a role. Classically, this condition is noninfectious, but many cases are noted to be associated with Corynebacterium species. Most patients affected are parous women with a mean age of 35, and many have breastfed within five years of diagnosis. Patients typically present with a painful mass and symptoms of inflammation, and these features can sometimes mimic breast cancer. Biopsy is needed to make a definitive diagnosis, and noncaseating granulomas are found on core biopsy. Many patients have a waxing and waning course over a period of six months to two years. Goal of treatment is to avoid surgery given poor wound healing, high risk of recurrence, and poor cosmetic outcomes. Medical treatment is preferred and includes observation, antibiotics, steroids, and immune modulators such as methotrexate. In more recent years, topical and intralesional steroids have become the treatment of choice, with similar outcomes to oral steroids.

Abstract
Idiopathic Granulomatous Mastitis (IGM) is an infrequent, benign breast disease that primarily affects women during their childbearing years and can be mistaken for breast cancer. This study aimed to review the clinical, radiological, and histopathological findings of patients with IGM in addition to management and outcome. Retrospective cross-sectional study of biopsy-confirmed IGM at an academic medical center and a private hospital in Amman, Jordan. Fifty-four patients were included, with a mean age of 37.0 ± 9.04 years, mostly presenting with a breast lump (n = 52, 96.3%) and breast pain (n = 45 patients, 84.9%). Approximately half of the patients (51.9%) were parous, and 50% had breastfed for an average duration of 30.37 ± 22.38 months. Most of the patients had either solitary or multiple abscesses on breast ultrasound. Histopathological analysis (n = 35) showed mostly either moderate inflammation (n = 16, 45.7%) or severe inflammation (n = 14, 40%). Two-thirds of the patients underwent surgical interventions at the time of diagnosis, mostly incision and drainage (n = 16, 29%) or surgical excision (n = 7, 13%), and no mastectomies were performed. The most common medical treatment included a combination of antibiotics, corticosteroids, and methotrexate (n = 21, 38.8%). After follow-up, 31 patients remained in remission, 3 experienced relapses, and 3 had a chronic course. The use of corticosteroids was significantly associated with remission (p = 0.035). The presentation and demographics of IGM patients in Jordan were consistent with the existing literature. Prospective research is needed to explore different treatment options and disease outcomes.

Abstract
Background: Idiopathic Granulomatous Mastitis (IGM) is a benign disease; it can clinically and radiologically mimic the symptoms of breast cancer. Objectives: Due to the rare and limited number of studies in Iran, this study was designed and conducted to evaluate patients' clinical characteristics and treatment management with IGM. Methods: In this cross-sectional and retrospective descriptive-analytic study, we studied the medical records of 293 patients with IGM, such as demographic information, characteristics of breast lesions, type of treatment, complications, and their outcome, which were recorded in the Cancer Research Centers of Shahid Beheshti University of Medical Sciences (SBMU) from 2010 to 2019. The patients were contacted by telephone to visit clinically or collect additional information. Data were analyzed by SPSS software version 24. Results: The mean age of patients was 39.21 (ST = 8.29) years. Breast involvement in 236 cases (80.5%) was unilateral, and in 50 cases (17.1%), the involvement was Pere pri-Areola. The most common type of treatment was conservative therapy (analgesia + drainage) (178 cases, 60.8%), which was the primary treatment in our study; 66 patients (22.5%) received antibiotic therapy + analgesia + drainage, and 41(14%) cases received corticosteroid in addition to this treatment. Totally, 132 cases (79.5%) were completely cured with the performed treatments, 17 cases (5.8%) had a recurrence of symptoms, and 14.7% of the patients were still receiving treatment. Recurrence after 1 year in patients who had a longer duration of disease (more than 12 months) was higher than in those who had a shorter period (less than 12 months) (15.3% vs. 5.1%, P = 0.004). Also, the highest recurrence rate was in the group receiving corticosteroids compared to the group receiving the usual treatment and usual treatment plus antibiotics. This relationship was statistically significant (22.0% vs. 9 % and 6.1%, respectively, P = 0.032). Complications (scar or breast skin color change) were significantly higher in patients without a pregnancy history than in patients who had pregnancy (50.0% vs. 22.8%, P = 0.030). Also, these complications were significantly higher in patients who had a longer duration of disease (more than 12 months) than in shorter periods of disease (less than 12 months) (31.4% vs. 17.3%, P = 0.005). Conclusions: The results of our study and its comparison with the results of other studies still emphasize the uncertainty of the etiology of IGM disease and its treatment, but to some extent, our study has shown that conservative treatment (drainage with analgesic drugs) is one of the best treatment options. Also, corticosteroid therapy is associated with a higher recurrence rate, but in some cases is necessary and recommended in many studies.

Abstract
Objectives This study aimed to retrospectively describe the clinicopathological pattern and management experience of idiopathic granulomatous mastitis in women receiving care at the Royal Hospital, a tertiary care centre in Oman. The study then compared the researchers' experience with the current literature trends. Methods The data of patients from January 2012 to December 2017 were reviewed retrospectively, after receiving ethical approval from the Centre of Studies and Research. Results This retrospective study included 64 patients were confirmed to have idiopathic granulomatous mastitis. All patients were in the premenopausal phase, with only one being nulliparous. Mastitis was the most common clinical diagnosis; furthermore, half of the patients had a palpable mass. Most patients had received antibiotics during the span of their treatment. Drainage procedure was done in 73% of the patients, whereas excisional procedure was done for 38.7%. Only 52.4% of patients were able to achieve complete clinical resolution within six months of follow-up. Conclusion There is no standardised management algorithm due to the paucity of high-level evidence comparing different modalities. However, steroids, methotrexate and surgery are all considered to be effective and acceptable treatments. Moreover, current literature tends towards multimodality treatments planned tailored case-to-case based on the clinical context and patients' preference.

Abstract
Background Idiopathic granulomatous mastitis (IGM) is a rare, recurrent and progressive breast disease with an unknown etiology. Patients with IGM will probably face stressful, time-consuming treatment procedures with side effects due to medications. There are different treatment modalities in clinical use including medical and surgical interventions. Objective The aim of this study was to present the results of using the combination therapy of low-dose methotrexate (MTX) and steroid in IGM. Methods Seventeen patients diagnosed with IGM and treated with MTX were included into the study. Low-dose MTX at 5 mg/week and 8 mg/day prednisone were given for 2-3 months. Results After 2-3 months of treatment, 10 patients exhibited (58.5%) complete, 3 patients (17.6%) partial recovery, and no response to the treatment process was observed in 4 patients (23.5%). No side effects of MTX and recurrent events were noted in any of the patients. Conclusion Low-dose MTX and prednisone treatment for IGM patients, who did not respond to steroids alone, should be considered as an alternative treatment method instead of surgical intervention.

Abstract
Distinct breast diseases are readily diagnosed by clinical and ultrasound appearance that radiologists and sonographers may encounter in emergency room and urgent care patient presentations. While it may be impractical or impossible for the on-call emergency radiologist to examine a patient with breast complaints, radiologists can and should adopt the practice pattern to routinely seek out the clinical photographs in the patient's medical record while interpreting breast examinations. Imaging should be interpreted in the context of both the history and the physical findings. Sonographers play important roles in the documentation of visual inspection findings, in addition to performing high quality targeted ultrasound where applicable. This pictorial offers resources to emergency radiologists and sonographers that facilitate rapid accurate diagnosis of ten distinct breast diseases.

Abstract
Idiopathic granulomatous mastitis (IGM) is a rare, benign inflammatory disorder of the breast. Clinical features may include painful breasts, erythema, subcutaneous nodules, and ulcerative lesions. It can mimic various other breast pathologies, and it is a diagnosis of exclusion after infection, malignancy, and other inflammatory conditions have been ruled out. In this article, we present a case of IGM developing in a 40-year-old female 3 months after hospitalization for myxedema coma. A contrast-enhanced magnetic resonance imaging of the breasts showed bilateral edema, and a biopsy was negative for malignancy or infection. She was started on prednisone and had noticeable improvement of ulcerations within several weeks. IGM is a rare condition that requires a multimodal treatment approach. Often recalcitrant disease is encountered and requires surgical intervention, immunosuppression, and antimicrobial therapy. The diagnosis should be entertained in patients with bilateral breast inflammation to avoid unnecessary surgical resection early on.

Abstract
Granulomatous mastitis (GM) is an under-recognized and under-diagnosed disease. Patients with GM often present to the emergency room with a painful breast mass, nipple retraction, and skin changes. This pictorial essay will review the clinical presentation and imaging appearance of GM, BI-RADS reporting parameters, differential diagnoses, and diagnostic challenges posed by this disease. Early and accurate diagnosis is essential, as misdiagnosis can result in repeated core biopsies, leading to fistulae and sinus tract formation. A classic history and typical sonographic appearance allow the emergency radiologist to confidently make this diagnosis.

Abstract
PURPOSE To evaluate the effectiveness of treatment with topical and intralesional steroids for idiopathic granulomatous mastitis (IGM) and to compare with surgical methods. METHODS Data were retrospectively collected from records. Intralesional steroid injection and topical steroid administration, hereafter referred to as local steroid treatment (LST) were applied in Group 1. Surgery (local excision, wide excision, and mastectomy) was performed in Group 2. In Group 1, changes in lesion sizes were recorded and factors complicating treatment were identified. The Numeric Pain Rating Scale was used to determine subjective pain. LST and surgery were compared with regard to: pain before and after the treatment; complication rate; recurrence rate; and treatment cost. RESULTS There were 38 and 48 patients in Group 1 and Group 2, respectively. In the LST group, 72 lesions were present and 70 of 72 (97%) responded completely to treatment. Pretreatment median maximum diameter was 23.50 (15.25-35.25) mm, which regressed to 16 (12-25) mm after the first session. While the pretreatment pain scores of Group 1 and Group 2 were similar (p = 0.756), there was a significant difference in the post-treatment pain scores (p < 0.001). No recurrence occurred in any patients in Group 1, while recurrence developed in 15 (31.2%) patients in Group 2 (p < 0.001). CONCLUSION LST is a treatment for IGM that is cheap, with high efficiency, negligible recurrence, and has good esthetic outcome. Our results suggest that LST should be the first-line treatment option for all IGM patients, including complicated cases.

Abstract
BACKGROUND The etiology of granulomatous lobular mastitis (GLM) remains unknown. This study aimed to detect bacteria in GLM using Nanopore sequencing and identify the relationship between GLM and Corynebacterium kroppenstedtii. METHODS AND MATERIALS The bacterial detection on fresh samples (including breast pus and tissue) of 50 GLM patients using nanopore sequencing and culture methods. The bacterial detection rate of participants with different stages were compared and analyzed. Formalin-fixed and paraffin-embedded (FFPE) tissues from 39 patients were performed on Gram staining to identify Gram-positive bacilli (GPB) within lipid vacuoles. Moreover, the clinicopathological characteristics of GLM patients in different bacterial subgroups were also conducted. RESULTS In 50 GLM patients, the detection rate of bacteria was 78% using nanopore sequencing method, especially in the early stage of GLM (over 80%), which was significantly higher than that using culture methods (24%, p < 0.001). The dominant bacteria were Corynebacterium species (64%), especially for the Corynebacterium kroppenstedtii. The detection rate of C. kroppenstedtii in nanopore sequencing method (56%) was higher than that in culture methods (16%, p < 0.001). Gram staining positive of bacteria in 7 patients, and 5 of them were C. kroppenstedtii. Thirty-one patients (31/39, 79.5%) exhibited typical histological structure of cystic neutrophilic granulomatous mastitis (CNGM), and eighteen patients detected with C. kroppenstedtii. CONCLUSION Nanopore sequencing showed rapid and accurate bacteria detection over culture method in GLM patients. GLM is not sterile inflammation and closely related to C. kroppenstedtii. CNGM was associated with Corynebacterium infection, especially for C. kroppenstedtii.

Abstract
Background Idiopathic Granulomatous Mastitis (IGM) is a benign chronic inflammatory breast condition that mimics two common breast disorders: breast carcinoma and breast abscess. It can form breast masses, fistulae, and fluid collections, resulting in breast disfigurement with retraction and nipple areolar complex (NAC) inversion. IGM most often presents in women of childbearing age within a few years of pregnancy, and can significantly impact lactation. Despite the prevalence of this disease, no current literature describes an approach to managing IGM during breastfeeding. Case presentation A 28-year-old G3P2 patient of Native American origin presented to her obstetrician at 7 months pregnant with worsening left breast swelling and redness. She underwent a mammogram, ultrasound and core needle biopsy that confirmed the diagnosis of Idiopathic Granulomatous Mastitis. During the postpartum period, she underwent intralesional triamcinolone injections of her left breast. Due to the contraindication of breastfeeding after local steroid injection, the patient stopped breastfeeding from the affected breast and continued breastfeeding unilaterally. Conclusions Idiopathic Granulomatous Mastitis is a challenging chronic inflammatory breast disease that affects women primarily in the reproductive years, with a higher incidence in patients of Hispanic, Native American, Middle Eastern, and African descent. Treatment of IGM during pregnancy and lactation has thus far not been addressed. We review the literature on the treatment of IGM in the non-lactating population, and propose considerations for treating breastfeeding women affected by this disease. Traditional treatment has included systemic immunosuppression and surgery, but newer literature demonstrates that intralesional injection of steroid can provide significant symptomatic relief to patients. A diagnosis of IGM does not preclude breastfeeding, though patients may experience challenges with milk production and latch on the affected breast. Individualized care should be provided, with considerations given to the following: side effects of systemic steroids, the need to wean a breast being treated with intralesional steroids, and augmentation of milk production on the unaffected breast to promote continued breastfeeding.

Abstract
BACKGROUND Idiopathic granulomatous mastitis (IGM) is a benign and rare chronic inflammatory disease of the breast with unknown etiology. While there is no consensus regarding its post-diagnosis management, there are different treatment alternatives. AIMS In this study, it was aimed to question the effectiveness of follow-up strategy without administering any treatment. METHODS One hundred eighteen female patients diagnosed with IGM were retrospectively evaluated. Patients with histopathologically confirmed IGM were included in the study. Medical treatment was given only to patients who did not accept the follow-up option without treatment. The protocol used in steroid therapy was 16 mg prednisolone twice daily for 2 weeks, and then the dose was gradually reduced, and the treatment was stopped after 2 months. Patients were followed up with a physical examination every 3 months. The effectiveness of the systemic corticosteroid treatment and the follow-up approach without any treatment was compared. The recurrence rates and pre-treatment and post-treatment methods of the patients were examined. RESULTS While 30.5% of the patients recovered with corticosteroid treatment, 42.4% recovered under observation without any treatment. The mean recovery period of the patients in these two groups was calculated as 3.9 months and 5.6 months, respectively. However, no statistically significant difference was found in terms of recovery period (p = 0.064). The recurrence rate was 11.9%. CONCLUSION For IGM, the "watch and wait" approach is an effective option. A chance should be given to the self-limiting nature of the disease with the addition of drainage when necessary.
