In the general population, the incidence of accessory breast tissue, a congenital malformation, is 1–5%. The most common site is the lower axilla. Detecting such tissue may be problematic, and accessory breasts below the umbilicus are extremely rare.
This report describes the case of a 5-day postpartum 29-year-old woman, G2P2, with painful vulvar swelling 6 cm in diameter. The patient was diagnosed with polymastia in the vulva, without polythelia, with galactostasis due to suturing of a birth laceration covering an excretory duct. The sutures were removed, and the pain decreased. Breastfeeding was continued.
Ectopic breast tissue is rare but should be taken into consideration in the differential diagnosis of a vulvar mass, especially postpartum in lactating women.
