Metastatic Squamous Cell Carcinoma of the Stomach from the Uterine Cervix: A case report

ABSTRACT

Secondary tumor of the stomach is rare when metastatic involvement is defined as an extragastric tumor invading the muscularis, submucosa or mucosa and the only serosal implant is excluded. Recently, authors experienced a case of metastatic squamous cell carcinoma of the stomach in the pyloric antrum from the uterine cervix. The patient was a 57-year-old female who received a simplified Wertheim's operation followed by irradiation for squamous cell carcinoma of uterine cervix in stage IIb, and 2-1/2 years later she presented gastric symptoms, for which subtotal gastrectomy was carried out. The gastric lesion simulated primary adenocarcinoma of Borrmann type III, but differed in the following macroscopic characteristics. Firstly, Bormann classification is not applicable; secondly, mucosal ulcerations appear irregular and multicentric; thirdly, flaskshaped ulceration and broad based penetration are evidet; fourthly, submucosal tumor-growth pattern is conspicuous in bulk of areas; and fifthly, circumferential/semicircumferential growth is manifested. The above features should also be differentiated from those of malignant lymphoma and leiomyosarcoma.
