Leiomyoosteochondroma of the stomach. A case report.
The case of a 65-year-old man with a large 6-year gastric tumour revealed echographically is reported. A well delimited consistent white-grey tumour occurring in the anterior wall of the stomach and projecting from the gastric serosa in the subhepatic region was surgically found. Histologically, it showed leiomyomatous zones with fascicular spindle cells and sometimes with perinuclear vacuolizations that are actin-reaction positive but protein S-100-negative. These zones alternated with large compact benign osteochondromatous ones. The uncertain origin of this uncommon tumour was discussed. We have not found any references to such gastric tumours.
