STOMACH - Leiomyosarcoma

The specimen is part of the stomach and shows essentially a raised nodular area with a smooth surface overhanging a large ulcer. The posterior surface of the specimen shows a nodular white lesion with areas of haemorrhage which is well-circumscribed and appears to be within the outer muscular coat.
This man presented at the age of 67 with a history of recent blood loss from the alimentary tract. He had had a gastric ulcer demonstrated some 10 years previously. The present lesion was found at operation; the histology of the lesion is that of a leiomyosarcoma. No metastases were demonstrated at operation.
