Myositis ossificans in the tip of the thumb: a case report

A case of a myositis ossificans occurring in the distal portion of the finger is reported. An 18-year-old female noticed a small nodule in the tip of the left thumb for 11 months. Plain radiographs showed calcified shadow and there was a radiolucent zone between the mass and the distal phalanx. The excised mass was diagnosed as myositis ossificans. To our best knowledge, there has been no report of a myositis ossificans in the tip of the finger in literature.
