BACKGROUND: @entity2118 (more commonly called @entity2967 ) is a @entity5 . CASE REPORT: A 17-year-old @entity1 had a tumefaction of the first toe. The mass was firm and painless and had been present for one year. Radiological studies revealed a cystic area of the first phalanx. Magnetic resonance imaging demonstrated a poorly vascularized tissular lesion. Surgical excision of the @entity5 was performed. Macroscopic and histologic findings confirmed the diagnosis of @entity2118 . DISCUSSION: Clinical and radiological aspects of @entity2762 are characteristic. This diagnosis should be made by dermatologists. Eighty percent of cases occur in fingers and more rarely in toes. @entity1 are usually females (60 p. 100). A subcutaneous mass is the most common presenting sign whereas @entity158 are rare. Optimal treatment is surgical resection. The only risk is recurrence (20 p. 100).
