| Abstract|| |
Male breast can show almost all pathological entities described in female breast. Inflammatory conditions of the breast in male are not common; however, occasionally, it can be encountered in the form of an abscess. Clinically, gynecomastia always presents as a symmetric unilateral or bilateral lump in the retroareolar region, and any irregular asymmetric lump raises a possibility of malignancy. Radiology should be used as a part of the triple assessment protocol for breast lump along with fine-needle aspiration cytology for definite diagnosis and proper management.

| Introduction|| |
In a large study by Singh et al., inflammatory lesion of male breast comprised of around 2% of cases in comparison to 86% of benign and 12% malignant tumors. Although gynecomastia is the most common lesion, many nonneoplastic entities are encountered in male breast such as sebaceous cyst, hematoma, fat necrosis, intramammary lymph node, and nodular fasciitis. Subareolar breast abscess is a distinct clinicopathological entity in male breast and can be encountered as a unilateral/bilateral breast lump with tenderness and pain. In majority of cases, predisposing factors such as altered immunity, iatrogenic procedure, trauma, nipple piercing, and diabetes mellitus may be documented. The causative organisms encountered in male breast abscess are staphylococcus, pseudomonas, salmonella, actinomycosis, and tuberculosis.,, The definite plan of treatment for such cases can be rendered by a fine-needle aspiration cytology (FNAC) report followed by a culture and sensitivity of the aspirated material.
| Case Report|| |
A 45-year-old male presented to cytology outpatient department with an irregular asymmetric nontender lump adjacent to the medial aspect of the left areola with slight retraction of the nipple for the past 6 months [Figure 1]a. He had a clinical diagnosis of gynecomastia/malignancy as the lump was not associated with pain or tenderness. He had a palpable left axillary node too. On FNA, 2 ml of pus-like material was aspirated from the lump. Multiple smears were made for Giemsa, Papanicolaou, and some special stains while the remaining material in the syringe was sent for culture. The smears showed numerous polymorphs, lymphocytes, macrophages, multinucleated foreign body type of giant cells, nuclear debris, and some capillary fragments. In addition, many Anucleated Squames were seen; however, no ductal epithelial cells were present in the smear [Figure 1]c and [Figure 1]d. The Ziehl–Neelsen stain was negative for any acid-fast bacilli while the periodic acid–Schiff stain did not highlight any fungal profile. With these cytological features, a diagnosis of breast abscess was rendered. The FNA attempted from the left axillary node showed features of reactive lymphoid hyperplasia. The microbiology report after 4 days did not reveal any organism on aerobic and anaerobic culture. The patient's blood sugar was within normal limit and HIV serology was negative. Ultrasonography of the left breast highlighted a 3 cm diameter heterogeneous lesion with multiple hypoechoic areas and internal moving echoes. There was mild increase in vascularity (color Doppler flow) in the periphery of the lesion [Figure 1]b. All the above imaging features were suggestive of an organizing abscess. The right breast was unremarkable on sonography.

| Discussion|| |
Breast abscesses are frequent in females, but only a few cases of male breast abscess are reported in literature. Breast abscess needs to be differentiated from mastitis clinically, however, on cytology; mastitis shows mixed inflammatory cells and ductal epithelial cells whereas abscess shows inflammation with anucleated squames. Breast abscess may be the sequelae of mastitis on many occasions; however, subareolar abscesses can happen even without mastitis. The epithelial cells when present with inflammation may show reactive changes so the interpretation of any atypia or malignancy should be made with caution. Any patient with breast lump should undergo triple assessment before any definite management with clinical evaluation followed by radiology and FNAC. Clinically, gynecomastia is a regular and symmetric lesion below the nipple-areolar complex; however, our patient showed an irregular and asymmetric lesion which raised clinical suspicion of malignancy. FNAC is much cheaper and easily accessible so it is the first investigation in Indian scenario and may not be followed by radiology on many occasions. On cytology, gynecomastia yields fat mixed aspirate and smears show scattered clusters of monomorphic epithelial cells with occasional myoepithelial cell in background. Imaging findings of breast abscess can mimic gynecomastia on mammography and may mimic malignancy on sonography. Usually, gynecomastia appears as a circumscribed discoid or triangular hypoechoic area located in the retroareolar region of the breast. Rarely, microcalcifications in abscess can appear suspicious and mimic malignancy. Most cases of subareolar breast abscess are unilateral, but rare cases can be bilateral also. The history of nipple discharge may or may not be elicited. These abscesses are treated with antibiotic therapy as per the culture and sensitivity report and surgical intervention may be required in persistent cases. Ziehl–Neelsen stain for acid-fast bacilli should be performed in all inflammatory breast aspirates as mycobacterium can be a causative organism of breast abscess in Indian setup.
| Conclusion|| |
Breast abscess in male is a rare condition which can be confused with gynecomastia and malignancy on radiological imaging. This lesion can be suspected with careful clinical evaluation and can be diagnosed accurately with FNAC along with culture and special stains to pinpoint the causative organism.
