Osteochondroma of the scaphoid in a 5-year-old child: A rare case report

Abstract

Osteochondroma is a benign bone tumor commonly arising from the distal femur, proximal tibia, and the proximal humerus. The common age of presentation is in the first two decades of life, particularly during periods of rapid skeletal growth. Tumors in the scaphoid bone are a rarity. Very few case reports have been published on benign tumors arising from the scaphoid including unicameral bone cyst, osteochondroma, osteoblastoma, and osteoid osteoma. We present a case of osteochondroma arising from the scaphoid presenting with pain and deformity of the wrist in an unusual age group of the first decade. Radiographs and magnetic resonance imaging suggested osteochondroma of the scaphoid. Tumor was resected, wrist deformity was corrected, and functional range was restored. Osteochondroma emanating from the scaphoid is considered to be extremely rare, but when the lesion is large and associated with progressive painful joint deformity as in our case, it warrants surgical resection.
