Two cases of heterotopic ossification occurring in a carcinoma of the stomach are reported. In one of these cases, bone formation is seen only in the regional metastasis, while in the other case, it is found in the primary tumor alone. In addition, there is seen in the former case a deposit of laminated psammoma bodies in the primary tumor and its regional metastasis. These two conditions are both so unusual for gastric carcinoma that only nine pertinent cases with heterotopic ossiflcation and two authentic cases with psammomatous calcification have been reported in the literature. The feature of these conditions la described and the pathogenesis discussed on the basis of personal Findings and a review of literature.
