Ectopic breast tissue represents any type of breast tissue found outside its normal location in the pectoral region. The second most common location for ectopic breast tissue after axilla is the vulvar region. We present a case of a healthy 20-year-old female, G1P1, who presented to the Emergency Department with a sudden increase in size of a painful mass located in her vulva, which started 4 days after a spontaneous vaginal delivery and 3 days after initiation of breast-feeding of her newborn. She reported a stable, smaller, painless mass in the same location for almost 2 years prior to this episode. After surgical excision, a fibroadenoma with lactation changes within ectopic breast tissue was confirmed.
异位乳腺组织是指在胸壁正常位置以外发现的任何类型的乳腺组织。腋窝之后，异位乳腺组织的第二常见部位是外阴区域。我们报告一例健康的20岁女性，孕1产1，因外阴部疼痛性肿块突然增大就诊于急诊科，该肿块在自然阴道分娩后4天及开始母乳喂养新生儿3天后出现。她报告在此之前近2年该部位有一个稳定、较小且无痛的肿块。手术切除后，证实为异位乳腺组织内伴有泌乳改变的纤维腺瘤。
