Hereditary multiple exostosis (HME) is a benign condition with multiple bony tumors with cartilage caps (osteochondromas), mainly presenting in the long and flat bones. Usually the presentation for HME is between 2 and 10years of age and most are seen by 4years of age (Khan et al. 2009). In this paper, we report a family with three members (father, son, and a daughter) who had very early presentations of HME in the fingers within the first 2years of age. The son presented with bony nodules at 7months of age, and he required surgery at 13months of age for a severe functional deformity of his left ring finger. He also had an unusual histological presentation on his osteochondroma that consists of only subperiosteal cartilage without ossification.
