Breast abscess in males is a rare condition, which accounts for 1%-3% of all documented breast diseases. Males with certain risk factors may develop a breast abscess. The ultrasonographic, mammographic, and pathological characteristics of this case will be highlighted in the report. A 51-year-old morbidly obese Saudi male who is a 160-pack-years smoker presented to our surgical clinic complaining of a right breast mass that presented a long time ago and was changing in size. The mass was painless until 5 days prior to presentation. On physical examination, a firm nonmobile 3 × 4 cm mass was felt at 10-12-o\'clock, 1 cm away from the nipple. A bilateral X-ray mammogram and ultrasound were performed with fine needle aspiration and culture. The mammogram of the right breast showed a well-circumscribed subareolar mass with equal density, and it was also associated with overlying skin thickening and relative breast parenchymal edema. The fine needle aspiration grossly showed yellowish-green turbid content followed by turbid blood. The anaerobic culture results showed the gram-positive cocci, Finegoldia Magna. The patient was then instructed to take an antibiotic accordingly and return after 1 week. Fine needle aspiration and culture were performed again after antibiotics and grossly showed 2-3 cc of pus without any growth in culture. Male breast disorders are typically benign, with gynecomastia being the most prevalent, and malignancy being the most serious despite its rarity. Breast abscesses are a challenging clinical condition, and radiologists have a pivotal role in evaluation and follow-up of these lesions.

A 17-year-old male with chest malformation and left breast enlargement underwent surgery for gynecomastia. Histological examination revealed mammary fibrous stroma with ductal hyperplasia and features of pseudoangiomatous stromal hyperplasia. Postoperative follow-up showed no complications, but 8 months later, the patient experienced a mild recurrence with enlargement of the nipple-areolar complex. Although recommended for secondary glandular resection, the patient declined further surgery.

Burkitt lymphoma (BL) is a poorly differentiated, aggressive form of B-cell non-Hodgkin\'s lymphoma. The clinical presentation of this disease is varied and may be nodal, extranodal, or both. BL of the breast, either primary or secondary, with bilateral breast involvement, is extremely rare. Herein, we present a case of BL in a 27-year-old male with unusual bilateral breast involvement.

UNASSIGNED: Primary breast lymphoma (PBL) is a very rare form of non-Hodgkin\'s lymphoma (NHL). A primary T-cell lymphoma in the breast with no previously identified lymphomatous lesions is an even rarer form of this malignancy.
UNASSIGNED: A biopsy of a breast mass in a 60-year-old Caucasian man showed a morphologic-immunophenotypic profile with features characteristic of an ALK-positive (AKT+), anaplastic large cell lymphoma. Fluorescence in situ hybridization (FISH) analysis of fixed, paraffin-embedded tissue of this lesion was performed at our institution for IRF4/DUSP22 gene rearrangement. No rearrangement was detected. The patient presented with mutations in the following genes; BCOR_p.Q600X, DNMT3A_p.F609fs, NOTCH1_p.P2320fs, and IDH2_p.R140Q. However, the patient\'s consultation was complicated by the fact that he had been diagnosed with breast cancer at a local hospital and had come to our institution for further consultation. The histology findings were confirmed by immunohistochemistry and FISH. Computed tomography and positron emission tomography did not reveal nodules elsewhere in the body, which allowed the staging of the patient to be completed. However, although the patient had previously received the chemotherapy CCOP regimen (ie, cyclophosphamide, vincristine, prednisolone acetate) he did not go into remission in a timely manner and relapsed after six months, followed by a drastic deterioration in his condition after four months, resulting in his death in less than one month.
UNASSIGNED: This report of a male patient describes a case of a rare T-cell lymphoma of the breast that occurs considerably more frequently in female patients. The differential diagnosis of the histology of this tumor showed mutations that occur more often in lymphoblastic lymphoma or leukemia. This rare malignancy and associated mutations led to the death of this patient during treatment.

UNASSIGNED: Breast imaging for male patients is a controversial topic due to the high prevalence of gynecomastia compared to male breast cancer. Worldwide, men are undergoing more breast imaging despite the low incidence of male breast cancer. Gynecomastia is a benign condition, but the anxiety it causes and unnecessary medical costs are still high.
UNASSIGNED: In accordance with Royal College of Radiology guidelines, a retrospective study was performed in two cycles to determine if mammography or ultrasound should be included in the workup of male patients who were referred to a breast care unit for a lump that was deemed benign by doctors.
UNASSIGNED: There was 100% concordance between clinical diagnosis and imaging findings.
UNASSIGNED: In this population imaging was not necessary in cases of probable gynecomastia and benign conditions found during a clinical assessment. Standardised patient assessment methods can improve care and ensure accurate evaluation.

This study describes a rare case of male granulomatous lobular mastitis (GLM) with recurrence in different sites on the ipsilateral side. A 48-year-old male patient presented with no previous history of breast-related disease, and physical examination suggested a mass in the right breast. Ultrasonography revealed a cyst and infection in the right breast. No obvious abnormality was found in laboratory analysis, and a core needle biopsy revealed GLM. Incision and drainage were applied to the right lesion, and symptoms resolved within a few weeks. At 2 years following this initial presentation, the patient reported that the right breast mass reappeared in different locations after the consumption of alcohol. Relevant examination and a core needle biopsy again suggested GLM of the right breast. The patient declined hormone therapy and was subsequently lost to follow-up. After reviewing this case, the course of the disease in this patient, and the connection between gynecomastia and GLM, along with ipsilateral recurrence, are under investigation.

Granulomatous mastitis (GM) is a rare disease, particularly among men. Herein, we present a case of GM diagnosed in a 63-year-old male patient who showed reduction in the tumor size during 3 months of observation.

Breast metastasis from extra-mammary neoplasm is a rare condition, accounting for approximately 1.2%-2% of all breast malignancies. Melanoma, lung cancer, gynecological, and hematological cancers can metastasis to the breast. Male breast metastasis is extremely rare and, no evidence of metastasis from cutaneous squamous cell carcinoma in a male breast have been reported to our knowledge. We describe a case of an 81-year-old man who came to our attention for a palpable solid mass in the upper-outer aspect of the left breast with the final histological diagnosis of breast metastasis from non-keratoblastic cutaneous squamous cell carcinoma.

UNASSIGNED: Fibroadenoma of the male breast is a rarely diagnosed lesion that often occurs concurrently with gynecomastia and the intake of medications that alter sex hormone levels. Herein, we report the first case of fibroadenoma of the male breast, presenting with medullary thyroid cancer. In addition, we reviewed the current management strategies for fibroadenoma of the male breast in the literature.
UNASSIGNED: A 25-year-old male patient presented to our surgical unit with medullary thyroid cancer (MTC). The physical examination revealed an unnoticed lump in his left breast. We delayed the planned thyroid surgery to determine whether the breast mass was associated with metastasis from MTC. We performed pathological tests from excised breast mass and confirmed the diagnosis of fibroadenoma. After confirming the benign nature of the breast mass, the patient underwent total thyroidectomy with selective neck dissection for MTC.
UNASSIGNED: Fibroadenoma of the male breast was diagnosed based on clinical presentation and histopathological findings. Fibroadenoma of the male breast is a rarely diagnosed lesion: and is often associated with gynecomastia and altered serum sex hormone level. The presentation of this case without those concurrences is even rarer, as revealed in our case. The management for suspected fibroadenoma of the male breast presented with MTC should include delaying the thyroid surgery to rule out the presence of malignancy and metastasis.
UNASSIGNED: The finding indicates that fibroadenoma can be considered a differential diagnosis in the male breast even in the absence of those concurrences. The timely diagnosis and orderly management of fibroadenoma of the male breast and MTC could help to improve the patient outcome.

Male breast lesions are relatively less common. The most encountered malignant lesion in the male breast is ductal adenocarcinoma; and benign lesions are gynecomastia, fibrocystic disease, intramammary lymph node, fibroadenoma, lipoma and epidermal inclusion cyst (EIC), respectively [5,6]. To date, there had been published only a few cases of EIC of the male breast in literature [3,5,6]. In this case, we aimed to present a new case of EIC with its clinical, radiological and pathological characteristics in the male breast. It had benign sonographic and magnetic resonance imaging findings but had also malignant imaging findings with diffusion restriction on diffusion-weighted imaging.
