Tubular adenoma with focal squamous metaplasia of the ascending colon.

A case of tubular adenoma with focal squamous metaplasia of the ascending colon in a 66-year-old male is reported. The tumor was a pedunculated polyp with a size of 1.5 X 1.4 X 0.9 cm. Histologically, the tumor showed tubular adenoma with moderate to severe atypia, was accompanied by focal squamous metaplasia. It is thought that squamous epithelial polyp may be derived from colonic adenoma with squamous metaplasia, and that the malignant change of colonic adenoma with squamous metaplasia may lead to squamous cell carcinoma, adenosquamous carcinoma, and mucoepidermoid carcinoma. Only seven cases of colonic adenoma with squamous metaplasia have been reported previously in the literature, and it is yet necessary to discuss the histogenesis, significance, and natural history of colonic adenoma with squamous metaplasia.

Minute mucosal patterns in gastric carcinoma. Magnification radiography of resected gastric specimens.

Magnification radiographs of 32 resected gastric specimens were used for analysis of minute gastric mucosal patterns according to the size and shape of the gastric areas and the appearances of the sulci between them. The mucosal patterns of 92 portions of stomachs were divided into 5 types and observed for correlation with their macroscopic appearances and histology. Destruction of the gastric areas and the sulci was predominant in the carcinomatous mucosa. However, among the patterns of noncarcinomatous mucosa, 18% of those with marked mucosal atrophy had abnormal mucosal patterns impossible to distinguish from carcinomatous mucosa.

Roentgen features of the superficial depressed type of early gastric carcinoma.

The superficial depressed type of early gastric carcinoma is described. The macroscopic appearance is characterized by an irregular erosion, often associated with a deeper central ulceration. The surrounding mucosal folds exhibit abrupt termination, narrowing, and clubbing. The roentgen diagnosis requires good demonstrations of detail. The double-contrast technique is most important and informative and can be used to study almost any part of the stomach.
