The disappearing exostosis? A report of an unusual case

Spontaneous resolution of a solitary osteochondroma of humerus following trauma: A case report with a review of literature

Osteochondroma is the most common benign bone tumor; however, the natural history of the lesion is still poorly understood. Symptomatic osteochondromas are treated with excision, but more often the indications are mainly cosmetic or fear of malignant transformation. There are few reports of spontaneous regression of solitary osteochondroma suggesting several theories causing their regression. We present one such case of a solitary osteochondroma of the humerus in an adolescent male, where a traumatic event resulted in the spontaneous resolution of the lesion.
