Vulvar lymphangioma circumscriptum: a report of 3 cases, 2 associated with vulvar carcinoma and 1 with hidradenitis suppurativa.

Vulvar lymphangioma circumscriptum is a rare, benign proliferation of the lymphatic system that presents a diagnostic and management challenge. It may be confused with condyloma acuminata, molluscum contagiosum, or other vulvar disorders. Treatment options include observation, surgical excision, laser ablation, or sclerosing therapy. We report 3 cases, 2 associated with vulvar squamous cell carcinoma and 1 with hidradenitis suppurativa.
