Fibroadenoma in the axillary accessory breast
A 30-year-old female noted a mass in her right axilla for 6 years. The mass was painless, slowly growing, causing discomfort, had cyclical changes in consistency and was of cosmetic concern to the patient. Examination revealed normal breasts and a soft, non-tender, broad based mass in the right axilla. Sonography was non-diagnostic. Diagnostic doubt, cosmetic concern and discomfort to the patient prompted excisional biopsy which revealed a 1 cm fibroadenoma with surrounding breast tissue and a diagnosis of fibroadenoma arising in accessory breast tissue was made. Surgical excision is recommended for symptomatic accessory breast tissue where diagnostic doubt exists and for cosmetic reasons.
