[Parietal tumors of the stomach]

The preoperative diagnosis, histopathology, clinical picture and treatment of tumours originating in the muscle and nerves of the stomach wall are described in the light of a series of cases collected over a period of 12 yr at the B Surgery Division, Varese District Hospital. Differential diagnosis and histological assessment of malignancy are not always easy. Transition forms exist in addition to those that are typically malignant or benign. Surgical management must take into account the extent, histological features and progess of the tumour. It can range from simple removal by enucleation to resection of the wall around the point of insertion of the tumour, or to distal, proximal or total gastroresection.
