[Gastric cancer presenting fine stippled calcification in radiography: a case report and a review of the Japanese literature].

A case of calcified gastric cancer is reported, with a review of the Japanese literature with special reference to the genesis of calcification. A male patient, 51 years of age, given a partial gastrectomy for an advanced gastric cancer 5 years earlier, presented general malaise. Plain X-rays revealed fine, stippled calcifications widely distributed in the upper abdomen. Additionally, computed tomography revealed a wide expanse of high density shadows with CT numbers of calcifications. On laparotomy, a histologic examination of a specimen taken for biopsy from part of the metastatic liver tumor led to a diagnosis of a mucinous adenocarcinoma showing identical histologic features of the previously resected gastric cancer, this diagnose then confirmed by Kossa's staining of fine calcified deposits in the tumor parenchyma.
