A case of squamous cell carcinoma arising in the body of the stomach is reported to describe its characteristics and the tissue generation, together with some discussion of the literature.
The patient was a 59-year-old male, with the cheif complaint of epigastric pain. Gastroscopy revealed a tumor (Borrmann type II) on the posterior wall of the body of the stomach. Biopsy of the lesion was performed, and squamous cell carcinoma diagnosed. The pyloric side of the stomach was resected and R2 curettage was performed. squamous cell carcinoma diagnosed. The pyloric side of the stomach was resected and R2 curettage was performed. Adenocarcinomatous tissue was not found in any other region. Metastasis to lymph nodes was positive to group II. Squamous cell carcinoma was noted in all the metastatic lesions.
Cases of squamous cell carcinoma in which adenomatous tissue is not observed, as in this case, are very rarely found; there have only been six such cases documented thus far in Japan.
