Abstract
Primary squamous cell carcinoma (SCC) of the stomach is rare. In this paper, the patient in Case 1 is a 57-year-
old man who underwent partial gastrectomy and adjuvant chemotherapy for primary SCC of the stomach. He
survives more than 4 years as of the writing of this report. The patient in Case 2 is a 49-year-old man who was also
diagnosed as primary SCC of the stomach. He died of massive gastric cancer bleeding 2 months after the diagnosis.
This report is followed by a literature review and further discussion of diagnostic criteria and palliative gastrectomy
in these patients.
Introduction
Gastric cancer is one of the most common cancers worldwide.
Te vast majority of gastric cancer is adenocarcinoma, accounting for
more than 90% of gastric malignancy. By contrast, primary squamous
cell carcinoma (SCC) of the stomach is rare, with an incidence of
0.04–0.07% [1]. In this paper, we report 2 cases of primary SCC of the
stomach.
Case Report 1
A 57-year-old man was admitted for a 2-week history of dysphagia
to solids. He complained of a sensation of throat obstruction seconds
afer swallowing food. He had no difculty swallowing liquids, and he
experienced no coughing or choking during food consumption. He
had smoked one pack of cigarettes daily for the past 30 years. Physical
examination provided unremarkable fndings. Furthermore, complete
blood count and diferential count as well as liver and renal function test
results were all within normal limits. Esophagogastroduodenoscopy
(EGD) showed a normal esophagus and esophagogastric (EG) junction;
however, a large tumor with central ulceration was noted in the gastric
cardia (Figure 1). Endoscopic ultrasound indicated a tumor measuring
3.0 × 4.2 cm and exhibiting heterogeneous echogenicity and a distinct
margin. Biopsy of the central ulcerative area revealed moderately
diferentiated SCC. Abdominal computerized tomography (CT)
indicated central necrosis within this gastric cancer but no evidence
of distant metastasis. Te patient was subjected to a positron emission
tomography (PET) scan for surveying possible extra-GI tract primary
malignancy, and the results demonstrated increased FDG radioactivity
only in the gastric cardiac area (Figure 2). On the basis of a diagnosis
Figure 1: Upper GI endoscopy of the gastric cardia. The tumor was located
in the gastric cardia.
Figure 2: The PET-CT scan showed that radioactivity uptake occurred only in
the stomach and excluded other primary malignancy origins.
