From question on page 1422
An abdominal operation revealed a hard whitish tumour. The tumour involved that part of the small intestine (fig 2
). On pathological examination it was diagnosed as a metastasis from a pleomorphic carcinoma of the lung (fig 3). Metastasis of lung carcinoma to the small intestine has been reported to be in the range 2.6–10.7% in autopsy studies.1,2 Some cases of small intestine metastasis showed various symptoms, such as obstruction, malabsorption, haemorrhage, and perforation. Berger et al reported that 0.5% of patients operated on for lung carcinoma developed symptomatic small intestine metastases.3 In this case, the shape of the small intestine metastasis was unusual. Cancer cells were substituted for normal cells all round the intestinal wall. Intestinal fluid passed through inside the tumour so that, although he had slight abdominal pain after meals, he did not have obstruction. Fortunately, it did not perforate.
