[Malignant glomus tumors of the stomach].

A total of 16 malignant glomic tumours of the stomach were studied. It is established that these tumours, as well as benign formations, have organoid structure, but differ from the latter by disorders of the tissue architectonics, polymorphism of cells of various degree, occasionally insignificantly manifested. The clinical course of the tumours not always corresponds to their histological structure--in mature microscopic structure they are sometimes characterised by local destructive growth and can give metastases. The authors propose to differentiate among malignant glomic tumours of the stomach the same variants of the morphological structure as in benign ones, i.e., myoid, angioleiomyomatous, angiopericytic, and paraganglioma-like. The authors assume that malignant glomic tumours of the stomach appear as a result of malignization of benign tumours.
