[Accessory breast on the vulva].

We describe a 24-year-old woman with a subcutaneous swelling in the left inferior pubic region. Histology revealed ectopic breast tissue. Vulvar tumors are uncommon and the presence of ectopic breast tissue in this region is extremely rare. In these cases, patients usually consult for a mass that varies in size with hormonal changes, typically during pregnancy or breast-feeding, or that has associated neoplastic changes. In our patient, the mass had grown progressively with no identifiable underlying hormonal association or neoplasm. We therefore classified it as ectopic breast tissue presenting as a subcutaneous mass. Copyright Â
