[Stomach leiomyoblastoma: contribution of cytology. Apropos of a case].

The authors report the case of a 51-year-old man with gastric leiomyoblastoma, presenting with a history of gastrointestinal bleeding and hemoperitoneum. CAT scan showed a mass measuring 10 x 10 cm arising from the stomach. At laparotomy the mass extended into the gastrosplenic omentum. A splenopancreatectomy was performed and the mass was excised for biopsy. The cytologic findings suggested a mesenchymal tumor; histology demonstrated the diagnosis of leiomyoblastoma. The postoperative course was uneventful. In the literature there is no evidence that intraperitoneal bledding from these tumors worsens survival. The cytopathologic features of leiomyoblastoma are discussed.
