Primary squamous cell carcinoma of the stomach: a case report.

Squamous cell carcinoma (SCC) originating from the stomach is a relatively rare entity. There are theories regarding the development of this rare tumor, but its exact pathogenesis remains obscure. Fewer than 100 cases of primary SCC of the stomach have been presented in the literature. Due to the advanced stage at the time of diagnosis in most of these cases, the prognosis is generally poor. In the case presented here, dissemination of the tumor to the transverse colon, gallbladder and omentum was present at diagnosis. Despite the tumor's advanced stage, complete remission was achieved after six courses of adjuvant chemotherapy with 5-flourouracil and cisplatin. No recurrence has been detected during follow-up. The patient has been healthy with no sign of the disease for three years.
