摘要
Giant cell tumor of the tendon sheath (GCTTS), tenosynovial giant cell tumor are a group of rare proliferative disorders which involves synovial joints and tendon sheaths. Considerable confusion exists about the surgical treatment and diagnosis of these disorders. We report an exceptional case of a tenosynovial giant cell tumor of the forearm. It concerns a 23 years old woman presenting multiple tumors of the forearm and wrist. Result of the primary biopsy concluded to an eosinophilic granuloma. Magnetic resonance imaging demonstrated a richly vascularized tissular lesion involving the extensor carpi radialis and extensor pollicis longus. Surgical excision of the tumor was performed. Macroscopic, histologic and immunohistochimic findings confirmed the diagnosis of tenosynovial giant cell tumor. This diffused form is rare compared with the nodular one involving fingers. Optimal treatment is surgical resection. The only risk is recurrence.
