[Complications of benign nonepithelial tumors of the gastrointestinal tract].

The results of observations over 8 patients with complicated forms of benign nonepithelial tumors of abdominal organs are reported, including leiomyoma--in 7 cases and neurinoma--in 1. Isocomplications of this group of tumors in 5 patients were as follows: invagination of the small intestin--in 1, perforation and malignant transformation of the tumor--in 1. The patients were treated surgically. Resection of the organ involved seems to be preferable.
