摘要
Schwannomas are solitary benign tumours derived from peripheral nerve sheath that are difficult to diagnose using imaging only. Diagnoses are commonly confirmed with conventional surgical resection. Small proportion of cases are formed by cellular schwannoma usually seen at paravertebral, pelvic, retroperitoneal, or mediastinal location. This patient had a 3 x 2 cm hard mass at the dorsal side of proximal phalanx of the right third toe. Bone destruction was seen on radiography and MR imaging. Curettage after excision and grafting were performed. No complication was seen after surgery. The histopathology result was reported as cellular schwannoma. It was an atypical location for cellular schwannoma not previously described in literature.
