위 (胃) 에 발생한 평골근아세포종 (平滑筋亞細胞腫) = A Case with Leiomyoblastoma of Stomach

다국어 초록 (Multilingual Abstract)

In 1960 Matein first described an unusual type of smooth muscle tumor of the stomach and 1962 Stout found the each tumor microscopically consisted of round or polygonal cells frequently containing of perinuclear vacuole or clear zone instead of the usual spindle cells as seen in the common leiomyoma and addressed this intramural tumor as a leiomyoblastoma. Since Stout reported a series of 69 cases, many clinical studies on this tumor have been published. In Korea Oh et al first reported a case of leiomyoblastoma of stomach in 1973 and thereafter two cases have been reported to date. 43-year-old housewife was admitted to this hospital because of dull pain on epigastrium and left upper abdomen with duration of two days last october 1985. Her condition was suspected as mesenteric cyst probably arising between stomach and pancreas. Whereas, surgery of the mass proved as epitheloid leiomyoma of stomach. As leiomyoblastoma has different clinical behavior and prognosis from leiomyosarcoma, special attention should be paid to this relatively rare tumor.
