Ectopic Breast Tissue in the Vulvar Region: A Case Report and Review of Literature

Ectopic breast tissue (EBT) is a rare congenital anomaly. It typically develops along the embryonic mammary ridge, with common sites including the axillae, while its presence in the vulvar region is exceptionally rare. This condition results from abnormal migration of breast tissue during embryonic development when the primordial mammary lines fail to regress completely. Diagnosis is challenging and requires clinical examination, imaging, and histopathological analysis to exclude malignancy. Treatment generally involves surgical excision to alleviate symptoms and reduce the risk of malignant transformation. We report a case of vulvar supernumerary breast tissue in a 46-year-old woman, confirmed through imaging and histopathological analysis following excision. This case highlights the importance of early diagnosis and surgical management to prevent complications.
