Pylorus showing an adenocarcinona

GC.6867

Pylorus and pyloric antrum. Half of a vertical section of the, showing an adenocarcinoma. From a female aged 47 years, who being seized with sudden vomiting a fortnight before admission to hospital, had felt a tumour in the superior segment of the abdomen, and thereafter a feeling of heaviness in the stomach with nausea after meals. The tumour was palpable, mobile, and moved with respiration. Its successful removal necessitated. the resection of two-fifths of the stomach. The mucosa of the pylorus and pyloric antrum is intact, but rough and nodular, and the pyloric lumen is restricted in calibre by the neoplasmic infiltration of its submucosa. The thickening of the pyloric wall reaches a maximum of 22 mm., and the carcinoma is obviously permeating the muscle. Microscopically the structure is that of an adenocarcinoma undergoing colloid degeneration.
