Primary squamous cell carcinoma of the stomach: a case report
1Department of Radiology, Loyola University, 2160 First Ave, Maywood, IL 60153, USA. kamuluru@gmail.com
Background:
Pure squamous cell carcinoma of the stomach is an extremely rare finding with a worldwide incidence of 0.04 - 0.07% (2).
Methods:
We present the case of a 78-year-old female who presented with a right hip fracture and was found to have worsening post-prandial vomiting and weight loss.
Results:
Esophagogastroscopy showed a 1.5 cm tumor located along the lesser curvature of the stomach. Endoscopic biopsy specimens of the tumor demonstrated primary squamous cell carcinoma. A workup for an extragastric squamous cell primary source was negative.
Conclusions:
The origin of pure squamous cell carcinoma of the stomach has not been well elucidated and thus several plausible theories have been proposed. In the presented case, the patient had a long standing history of gastric erosions and the tumor was adjacent to significant inflammatory mucosa. Therefore, it may be considered that the tumor arises from squamous metaplasia secondary to chronic mucosal damage.

01:17Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...
