Abstract
Soft tissue osteomas are very rare and should be differentiate from other osseous lesions of soft tissue. We present two patients and discuss their clinical, radiologic and histopathological features with literatures. The first patient was 17-year-old boy, amateur football player. The other was a 43-year-old man had a firm, painless mass at his right knee. Their medical history had both trauma to their knees. Radiologically, heterogenous nodular calcification areas were observed near the proximal metaphysis of their tibias. Hardly lobulated lesions without bone attachment at the ligaments were excised. These lesions were gray-white coloured, well-circumscribed, firm masses. Microscopically, welldefined, lobulated lesions were involved mature lamellar bone trabeculae and enchondral ossification areas at peripherial portion. Both of our patients are survived healty for four years.
