title: A case of cornstarch granuloma.
abstract: A 57-year-old female was diagnosed as having asymptomatic cornstarch granuloma. The disseminated small nodules over the peritoneum were incidentally discovered at operation for cholelithiasis, when she was misdiagnosed as carcinomatosis peritonei. Histological observations revealed a characteristic finding of tuberculoid granuloma with caseous necrosis, a rather rare histological type of cornstarch granuloma. Polarized light microscopic examination of biopsy specimens is particularly important for the diagnosis. We emphasize that cornstarch granuloma should once be considered when tuberculoid or unknown abdominal granuloma are observed in patients with history of abdominal surgery.
