Description

In a 52-year-old man, a cutaneous malignant melanoma developed concurrently with an adenocarcinoma of the right lung. The latter disseminated widely, and autopsy disclosed that it had also metastasized to the dermal tissue involved with the melanoma. Because it was not a metastasis into the substance of the melanoma, it was classified as an unusual type of 'collision tumor' rather than a 'cancer-to-cancer' metastasis.
