A case of leiomyoblastoma of the stomach and a review of the Japanese literature were reported.
The patient was a 37-year-old female whose chief complaint was discomfortness in the epigastrium.
In this case, Gastro Intestinal series, gastroscopy, and angiography were performed.
The histological diagnosis was made by endoscopic biopsy from the ulceration of the tumor preoperatively.
Under the diagnosis of leiomyoblastoma of the stomach, distal gastrectomy was performed with removal of lymphnodes.
Reviewing in the literatures it is difficult to make a histological diagnosis preoperatively. Histological diagnosis was made in only 4 out of 19 cases by biopsy from the ulceration and the dimple of the surface of the tumor.
In 16 out of the 19 cases, ulceration and a dimple were found on the surface of the tumors.
It is important to take the biopsy specimen from this area in order to make a histological diagnosis preoperatively.
Reviewing the Japanese cases revealed that one total gastrectomy, two subtotal gastrectomies, and distal gastrectomy in the remainder were performed with or without removal of lymph nodes.
The method of the operation should be established in the near future in regard to the size, the type of growth, and the degree of malignancy of the tumor.
