平滑筋腫と潰瘍が胃の同一部位に共存した1例

A Case Report of Leiomyoma associated with a Peptic Ulcer in the Same Region of the Stomach

　胃平滑筋腫は臨床的には比較的稀な疾患であるが，それに胃潰瘍の合併した症例は更に少ない．最近，著者らは筋腫と胃潰瘍が同一部位に共存したきわめて稀な1例を経験したので報告する．

　One case of leiomyoma of the stomach associated with a peptic ulcer in the same region is reported.

　The patient, a 65 years old male, was admitted to our hospital with complaints of epigastralgia and tarry stool. Upper gastrointestinal X-ray series and gastroscopic study demonstrated a gastric ulcer at the lesser curvature of the corpus. Gastric biopsy was negative for malignancy. Subtotal gastrectomy was performed, because the ulcer was very large and deep.

　Gross findings of the resected stomach revealed a chronic ulcer, 3.5×3.0 cm in size (Ul-Ⅳ), and a tumor located beneath the ulcer. Histology proved that the tumor was leiomyoma.

　Gastric leiomyoma is relatively a rare occurrence. The incidence of complication of gastric ulcer with leiomyoma in the same individual was quite infrequent with only a few cases reported in Japan. Another case similar to ours, in which leiomyoma and ulcer were located in the same gastric region, was reported only by Rabinovitch et al.
