Abstract
Nipple adenoma, an uncommon benign tumor, typically appears between the fourth and fifth decades of life, occasionally manifesting in accessory breasts. The embryonic mammary ridges give rise to accessory breasts along the milk line, and the lack of involution results in supernumerary breasts, including accessory nipples. This study aims to report a case of adenoma originating from an accessory breast nipple. The present study describes the case of a 23‑year‑old female patient who presented with right axillary discomfort and swelling. A physical examination revealed a tender, non‑inflamed lump. A breast ultrasonography revealed features compatible with an accessory nipple, confirmed by excisional biopsy revealing adenoma. Throughout the 4‑month follow‑up period, no signs of recurrence were observed. Although rare, accessory breast tissue can harbor neoplasms, with nipple adenoma posing a diagnostic challenge often confounded with Paget's disease. Histologically, nipple adenomas exhibit diverse patterns, emphasizing the importance of a precise diagnosis. Adenoma of the accessory nipples is a rare condition that necessitates proper clinical assessment. Surgical excision remains the standard, yielding favorable outcomes.
