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 t
he tip of the left thumb for 11 months. Plain radiographs showed calci
fied 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 ossific
ans in the tip of the finger in literature. (C) 1998 Tohoku University
