Accessory breast tissue, the most prevalent variant of the breast, is more common among females than males. In children, it is most often noticed in the adolescence period due to hormonal stimulation. Accessory breast tissue is most frequently seen along the milk line between the inguinal region and the axilla. It may be asymptomatic or symptoms, such as pain, tenderness, and mass enlargement, may occur during menstruation. Ultrasonography, magnetic resonance imaging (MRI) and mammography may assist in diagnosis. Surgical excision and histopathological examination are needed to eliminate a potential malignancy. In this study, a case of bilateral axillary breast tissue with fibrocystic changes in a 16-year-old female patient was presented. The mass in both axillary regions was completely excised. As a result of histopathological examination, it was revealed that both masses were breast tissue with fibrocystic changes. In conclusion, accessory breast tissue should be considered among the differential diagnoses in patients with unilateral or bilateral axillary mass complaints. It is important to emphasize that accessory breast tissue has the potential for benign and malignant breast diseases.
