ABSTRACT
Gastric leiomyoblastoma is an uncommon intramural tumor, Its been regarded as a tumor of smooth muscle origin by its histological and electronmicroscopic characteristics. However, recent immunohistochemical staining techniques have shown that tumors diagnosed as leiomyoblastoma may have different tumor origins. We report a case of multiple leiomyoblastoma of the stomach thought to be of unknown derivation by Immunohistochemical study.

Leiomyoblastoma is uncommon and has been known as a neoplasm of smooth muscle origin. However, with recent pragress in immunohistochemical staining techniques, many clinicopathological discrepancies have been pointed out about the origin of leiomyoblastoma. We present here a case of gastric leiomyoblastoma did not expressed desmin and neuron specific enolase, and was thought to be of unknown derivation.
