Cutaneous metastasis of gastric adenocarcinoma: an exuberant and unusual clinical presentation.

There are different types of skin changes associated with internal malignancy. One type is the skin involvement as a result of cutaneous metastasis from an internal tumor. The skin is an uncommon site for distant metastasis; when it is present the most common sources are breast, lung, and colon. Metastasis generally occurs after an internal malignancy had been discovered and signifies disseminated disease with a poor prognosis. We report an exuberant and rare case of cutaneous metastasis from gastric adenocarcinoma as the first sign of this serious visceral cancer.
