Ectopic mammary tissue in vulva.


The mass was removed by wide local excision. Histopathological assessment revealed features of ectopic mammary tissue


The vulvar region is one of the reported sites for ectopic breast tissue in the body. The presence of a rapidly enlarging, well-encapsulated mass in the vulvar region associated with recent delivery or lactation is suggestive of ectopic breast tissue.
