This report describes a 28-year-old male with a fibrovascular tumour of the left midpalm, extending into the carpal tunnel. It compressed the median nerve, producing carpal tunnel syndrome. Upon carpal tunnel decompression and local excision, the symptoms were relieved. Histopathological study of the tumour revealed characteristics suggestive of fibroma of tendon sheath, an uncommon tumour of the hand and rare cause of carpal tunnel syndrome.
