Cutaneous metastases from gastric adenocarcinoma. Report of two cases and review of the literature

The skin is rarely involved by metastatic tumors. Breast and pulmonary carcinoma are the most frequent primary lesions that may spread to the skin. Head and neck, chest and abdominal wall are the commonest sites of cutaneous metastases. The authors report two cases of cutaneous metastases from gastric adenocarcinoma, one of which is particularly interesting as it developed on the extremities, a very rare site for skin metastasis. The authors also stress the differential diagnosis with primary cutaneous adenocarcinomas.
