Abstract

In 1901, Askanazy made a report on a case of heterotopic bone formation in the laparotomy scar. Since that time, many cases of this phenomenon have been reported in Europe and in the United States. According to Piculachs et al, such cases amout to even 230 cases. In Japan, Hayashi was the first to make a report on heterotopic bone formation in 1938. Since that time, the cases accumulated over a period of 50 years only amount to 76 cases. This total includes one case experienced in our Department. The case is a 59-year-old male. A diagnosis of cholelithiasis was made; the gallbladder was extracted through an upper mid-line incision; and a T-tube drainage operation was performed. Eight years and six months after the operation, a 15 cm hardness along the surgical scar was revealed and was accompanied with pain. After various examinations, this case was diagnosed as heterotopic bone formation and underwent surgery to have the bone resected. The above case will be discussed.
