Unilateral Enlarged Right Accessory Axillary Breast Tissue in a Male: A Case Report

Accessory breast tissue, associated with polymastia and polythelia, presents challenges and concerns, particularly when patients fear malignancy. While occurring in 1-6% of cases, accessory breasts, often located bilaterally in the axillae, necessitate careful examination. We report a 35-year-old male with painful axillary swelling who underwent high-resolution ultrasonography (HR-USG) and fine-needle aspiration cytology (FNAC), revealing proper axillary breast tissue. Subsequent excision biopsy confirmed accessory axillary breast without malignancy. In conclusion, surgical removal of accessory axillary breasts is advisable, addressing cosmetic concerns and minimizing cancer risks.
