Anaplastic carcinoma of the esophagus. Report of three cases and their histogenetic consideration.

The autopsies of three cases of esophageal anaplastic carcinoma with an oat cell pattern are presented. Grossly, each case revealed a fungating growth and showed extensive metastases all over the body. The histology bears a striking resemblance to that of oat cell carcinoma of the lung, occasionally showing rosette formation, mucin secretion, and intracytoplasmic argyrophil granules in each case. These peculiar carcinomas most probably were derived from the esophageal submucosal glands. They were composed of both a cell group of argyrophil variety and a group of mucus-secreting variety which may have originated from the more primitive cells capable of differentiation into either variety.

Pseudosarcoma and carcinosarcoma of the esophagus.

Two cases of polypoid carcinoma with pseudosarcoma and one of so-called carcinosarcoma of the esophagus are presented. The clinical and morphologic characteristics of these tumors are described and the literature is reviewed. It is postulated that pseudosarcomas and so-called carcinosarcomas belong essentially to the same pathologic entity because of their similar morphologic and biologic aspects. The histogenesis of the sarcoma-like elements of these tumors support the theory of epithelial origin on the basis of the sarcoma-like transformation of squamous cell carcinoma and of the presence of epithelial elements in the "sarcomatous" areas.

Gastric carcinoma with lymphoid stroma. Its morphologic characteristics and prognostic correlations.

A type of gastric carcinoma was specified under the designation carcinoma with lymphoid stroma. Grossly, this carcinoma was characterized by clear circumscription, usually with a central ulceration. A histologic feature distinguishing this carcinoma was the presence of a nondesmoplastic stroma infiltrated uniformly with an abundance of lymphocytes and plasma cells throughout the entire area of the tumor. Sparse population of less pleomorphic cancer cell nests of thin trabecular, microalveolar, or primitive tubular pattern widely separated by the intervening stroma was another feature peculiar to this tumor. Carcinoma of this type was found in 4% of a total of 1041 cases of gastric carcinoma removed surgically. A high survival rate was noted among the patients undergoing surgery for this carcinoma. A proposal was made on the separate classification of this tumor from common gastric carcinomas.
