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-l/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,
flask-shaped ulceration and broad based penetration are evident; 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.
