[A case of leiomyoblastoma of the jejunum]

Reported is a submucosal tumor of the jejunum that had developed in a 46-year-old man who manifested general fatigue and anemia. The tumor measured 3.0 x 3.0 cm and was composed of polygonal and/or round cells with a clear zone surrounding the nucleus. Five mitotic figures per 50-power fields were present. The light microscopic appearance was consistent with those of a Leiomyoblastoma. Follow-up evaluations approximately 2 years after the resection showed no evidence of metastasis or recurrence.
