Ectopic breast tissue (EBT) occurs in 0.3-6% of females and is typically located in the axilla, but it can also be found in the vulva. Diagnosis often occurs when there are hormonal changes that influence growth and development of the tissue. Due to symptomatology and malignant potential of this ectopic tissue, excision is typically recommended. We present the case of a 31-year-old woman, gravida 1 para 1001, attended four weeks after a normal vaginal delivery for a painless vulvar mass. Incision, drainage and biopsy were performed, revealing ectopic breast tissue with lactational changes. Simple partial vulvectomy revealed fibrocystic and lactational changes in mammary tissue of the vulva without atypia or malignancy. Our case displays a rare finding of aberrant, lactating breast tissue presenting in a postpartum patient.

Gestational trophoblastic disease (GTD) is a term used for a group of pregnancyrelated tumors arising from defective proliferation of trophoblastic tissue. Its incidence after term pregnancy is infrequent, being diagnosed in most cases incidentally, due to symptoms of metastasis. We present a case of GTD that occurred 9 weeks after a vaginal delivery at term. The serum beta-human chorionic gonadotropin (β-hCG) level was 38 084 mIU/mL and a chest CT scan showed multiple pulmonary nodules. The patient received actinomycin D for 3 cycles. The β-hCG normalized after the third cycle and the patient remained disease-free for 12 months after diagnosis. The clinical presentation and challenges in diagnosing GTD in the late postpartum period are described.
