title: [A case of cystic changes in a giant leiomyoblastoma of the stomach].
abstract: A 44-year-old male was admitted to hospital with a complaint of abdominal distention. A CT scan revealed a giant multicystic mass in the abdominal cavity, a tumor that measured 34 cm in diameter, which had risen from the gastric body and grew in an exophytic fashion with a stalk. Histologic findings exhibited a malignant leiomyoblastoma with cellular pleomorphism and a intracytoplasmic cystic change, which included disseminated nests of immature small round cells. After excisional surgery, the patient has had no sign of a recurrence for the past two years.
