Summary Removal of an adenocarcinoma of the ascending colon was followed within 10 months by the development of a solitary focus of metastasis in the skin and subcutaneous tissue of the right arm. The metastatic tumor, which appeared to be of hematogenous origin, grew at the site of hypodermic injections and possibly involved a granuloma caused by the injections. Despite the ominous evidence of systemic spread, the patient has lived 10 1/2 years, in good health, and is currently free of evidence of recurrent or metastatic carcinoma.
