Pregnancy-related vulvar fibroadenoma of ectopic breast tissue is rare. Management involves diagnosing the mass as a fibroadenoma by physical examination and delaying excision until the postpartum period.


A 31-year-old multigravid woman at 29 weeks' gestation had a right labial mass that was increasing in size. Physical examination showed accessory breast tissue in the left axilla and three vulvar masses, the largest vulvar mass measuring 4 × 5 cm. Suspicion of malignancy was low, so the patient was serially examined during the pregnancy and the vulvar masses were excised during the postpartum period. The final diagnosis was fibroadenoma of ectopic breast tissue.


Fibroadenoma of ectopic breast tissue can occur during pregnancy. Diagnosis and serial physical examinations are the appropriate course of management during pregnancy. A fine-needle aspiration biopsy can be performed during pregnancy to confirm the diagnosis. The tumors seldom regress spontaneously and so should be removed during the postpartum period.
