title: [Gastric epithelioid leiomyoma (leiomyoblastoma). Analysis of a case and review of the literature].
abstract: The authors report a case of gastric epithelial leiomyoma (leiomyoblastoma). Macroscopically, such tumors resemble leiomyoma, with a biological behavior between leiomyoma and leiomyosarcoma. A review of the medical literature indicates that gastrointestinal bleeding is the most usual manifestation. Gastrointestinal seriography and endoscopy are the most utilized diagnostic exams. The endoscopic biopsy, many times, is unable to confirm the malignant or benign nature of the tumor. It is emphasized the importance of identifying the potentially malignant tendency of the tumor, indicated, mainly, by histology and mitotic counting. The treatment is surgical and consists of local or gastric resection, according to the neoplastic localization, its extension, infiltration, biological nature and the presence of multiple tumors. In the case reported, the patient was operated in urgency because of hemoperitoneum and the source of bleeding was a neoplastic vessel in the anterior wall of the antrum, which was not resected at that time. Later on, a biopsy of the gastric tumor performed during a routine surgery disclosed the real nature of the disease. Once the histopathological diagnostic was made and its potential malignant evolution detected the patient was re-operated. A partial gastrectomy with removal of the antrum was performed. Now, the patient has been asymptomatic with no evidences of metastasis after 30 months of the diagnostic.
