Lipoma of the hand is a common lesion, but lipoma arising from the flexor tenosynovium is a very rare tumor that induces peripheral nerve disorders. Only four cases of synovial lesions that comprised mature fat at the wrist and imitated carpal tunnel syndrome have been described in the literature. We herein report an unusual case of a lipoma arising from the flexor tenosynovium at the level of the ring finger just proximal to the A1 pulley that was responsible for a sensory disturbance of the ring and middle fingers secondary to compression of the common digital nerve at the palm. The patient was completely relieved of the symptoms after lipoma excision.
手部脂肪瘤是一种常见病变，但起源于屈肌腱滑膜的脂肪瘤是一种非常罕见的肿瘤，可导致周围神经疾病。文献中仅描述了4例腕部包含成熟脂肪并模仿腕管综合征的滑膜病变病例。我们在此报告一例不寻常的病例，一名患者的屈肌腱滑膜脂肪瘤发生于环指近A1滑车处，导致手掌部指总神经受压，继发环指和中指感觉障碍。脂肪瘤切除术后，患者症状完全缓解。
