Heterotopic bone formation in laparotomy scars has not often been described. A case is presented and the literature is discussed.<BR>Case. A 62-year-old man presented in June 1974 with a stabbing sensation in the abdominal wall, usually initiated by flexion of the the abdominal wall musculature. A hard mass, palpable in the middle upper abdominal scar, was thought to be heterotopic bone formation. He had a history of a laparotomy through a middle upper abdominal incision for gastric ulcer, in November 1971<BR>On admission, a laparotomy was performed through the site of the previous incision, and bony material, 14.5 × 2.0 × 1.0 cm, was identified in the old scar. Histopathology confirmed the presence of bone and bone marrow.<BR>In this case, "cell metaplasia" theory was surmised as to the etiology of the heterotopic osteogenesis.
