Nine patients with rare epithelioid leiomyosarcoma in gastrointestinal tract studied in this series showed a long course of disease and survived for over 5 years even after evident metastasis occurred. Morphologically, the neoplasm was similar to epithelial tumors, so often misdiagnosed as carcinoma unless special strains such as reticulum, Van Gieson and Masson trichrome or immunohistochemical staining were given. Prognosis cannot be predicted only on the basis of histologic appearance because of its slow development, late metastasis and long survival time.
