To report the case of a patient with a large and symptomatic vulvar lesion, necessitating surgical excision.
We report the case of a 57-year-old postmenopausal woman with a 6-month history of an enlarging vulvar lesion associated with vulvar pruritus. On examination, a pedunculated 7 × 5 × 4-cm soft tissue mass attached to the left labium majus was noted. Surgical excision was performed and histopathologic evaluation revealed variably dilated, submucosal vessels with thick muscular walls and intimal thickening, but without endothelial atypia or multilayering. These findings were consistent with a final diagnosis of arteriovenous malformation of the vulva.
Given the complex anatomy of the vulva, the differential diagnosis for vulvar vascular lesions can be challenging. Hence, surgical excision and histopathologic evaluation become imperative to distinguish them from other dermatologic and neoplastic conditions of the vulva.
报告一例因外阴大而有症状的病变，需行手术切除的患者病例。
我们报告一例 57 岁绝经后妇女，外阴瘙痒 6 个月，外阴病变逐渐增大。检查发现左侧大阴唇有一 7×5×4cm 大小的带蒂软组织肿块。行手术切除，组织病理学检查显示，黏膜下血管不同程度扩张，厚壁肌性血管，内皮层增厚，但无内皮异型性或多层化。最终诊断为外阴动静脉畸形。
鉴于外阴的复杂解剖结构，外阴血管性病变的鉴别诊断具有挑战性。因此，手术切除和组织病理学评估对于将其与外阴其他皮肤病和肿瘤性疾病区分开来至关重要。
