Overview

Osteochondromas may be classified into 2 subtypes: solitary osteochondromas (non-hereditary) and multiple osteochondromas (hereditary).^[1]

Classification

The table below differentiates between the 2 subtypes of osteochondromas:^[1]^[2]^[3]^[4]^[5]^[6]^[7]


Type of Osteochondroma	Features

Solitary osteochondroma	Non-hereditary 85% of osteochondromas No genetic mutations Located in long bones Onset is in early adolescence
Multiple osteochondromas	Hereditary Approximately 20% of osteochondromas Related genetic mutations EXT-1 and EXT-2 Early onset of disease (newborn or children)
