A Solitary Enchondroma of the Great Toe in an Adolescent Male: A Case Report

Abstract

Solitary enchondromas are benign and usually asymptomatic. Enchondromas are a form of cartilage tumor and have a higher chance of converting into chondrosarcoma. It is difficult to obtain a valid risk estimate, as this requires histopathology and MRI reports. A 17-year-old male presented with swelling over the left great toe since six months, which was insidious in onset, gradually progressive, and associated with intermittent dull aching type of pain. Physical examination revealed bony hard swelling of size 3 x 2.5cm over the left great toe. X-ray was suggestive of lytic lesions, scalloping of the cortex, and whorl of calcification. After confirming the diagnosis through MRI and histopathological examination, the decision was taken to remove whole of the proximal phalanx along with the tumor. Gap was filled up with fibular strut graft. Solitary enchondromas that are aggressively increasing in size should be treated surgically. Bone gap (between the first metatarsal and distal phalanx) caused after removing the tumor can be filled with bone graft or cement depending on the condition of the cortex.
