    Abstract:
    BACKGROUND: Pigmented nodular tenosynovitis (more commonly called giant cell tumor) is a benign tumor of synovial joint or tendon sheaths. CASE REPORT: A 17-year-old girl 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 tumor was performed. Macroscopic and histologic findings confirmed the diagnosis of pigmented nodular tenosynovitis. DISCUSSION: Clinical and radiological aspects of nodular tenosynovitis are characteristic. This diagnosis should be made by dermatologists. Eighty percent of cases occur in fingers and more rarely in toes. Patients are usually females (60 p. 100). A subcutaneous mass is the most common presenting sign whereas pain or joint swelling are rare. Optimal treatment is surgical resection. The only risk is recurrence (20 p. 100).
