In brief
Retrospective study of 11 adolescent girls with axillary ectopic breast tissue treated surgically via minimal incision approach. All patients achieved excellent cosmetic outcomes with no recurrences at one-year follow-up, supporting bilateral ultrasonography for diagnosis and early excision as safe, effective management.

Abstract
Aim
Ectopic breast tissue (EBT) includes a spectrum of disease that entails other entities based on the presence of glandular tissue, nipple, or areola. The diagnosis in adolescents is infrequent.
Methods
A retrospective study was performed including girls with axillary EBT (class IV or V of Kajava’s Classification) operated in 2006–2020. Imagining studies, clinical and surgical reports, and histopathology were reviewed.
Results
Eleven girls from 13 to 16 years old were included. Two patients (18.2%) presented bilateral EBT. The most frequent clinical manifestation was 2–5 cm mass (100%), associating cyclic pain with menstruation (45%) and fluctuating volume (36%). Bilateral axillary ultrasonography allowed preoperative diagnosis. All of them were treated by open excision, through small incisions located in an axillary y fold. Clinical and aesthetic results were self-assessed as “very good”, with normalization of the axillary y hollow and imperceptible scars. No recurrences were observed after one year of follow-up. An immediate postoperative hematoma was reported, which did not require drainage. Histopathology showed mature breast tissue without atypia.
Conclusions
Axillary accessory breasts must be included in differential diagnosis of pediatric axillary masses. Bilateral ultrasonography is recommended for the preoperative diagnosis. Excision through minimal incision at this age seems to be safe and effective.
