Para-articular osteochondroma is a benign osteoarticular tumor which develops near joints, extremely rare unlike classical osteochondroma.We report a case of para-articular osteochondroma of the right knee localated in the medial condyl of a 13 years old child with history of chronic knee pain and limited knee movement. On clinical examination, a solid palpable mass in the intern joint region was detected. Radiography and MRI of the knee revealed the diagnosis of solitary osteochondroma. The mass was entirely removed through an open approach medial to the petella. Histologic examination showed that the nodules were composed of cartilaginous tissue surrounded by fibrous connective and adipose tissue with multifocal endochondral ossification.
