Endoscopic observation of squamous metaplasia of the stomach: a report of two cases.
Squamous metaplasia of the stomach is a rare clinical entity that occurs during healing of gastric ulcers or chronic inflammation. We have treated two patients with this condition, which has only occasionally been observed endoscopically. The first was a 60-year-old woman who initially presented with multiple gastric ulcers. Two months after treatment, a white patch about 4 cm in diameter was found in the lesser curvature of the cardiac region of stomach. The second patient was a 65-year-old woman, who also developed a white patch in the same region. Two months later, a small ulcer and inflamed mucosa were seen near the lesion. The white areas in both patients were stained with Lugol's iodine solution, and biopsy specimens confirmed squamous epithelium. The squamous metaplasia was observed as a white mucosal area in the stomach, and the metaplastic area stained positively with Lugol's iodine solution.
