Abstract

Cutaneous metastasis from visceral malignancies shows diverse manifestations. Very rarely, cutaneous metastasis mimicks benign mesenchymal tumors. We describe a case in which metastasis from gastric adenocarcinoma mimicked fibrohistiocytic tumors. The diagnosis of cutaneous metastasis was confirmed by the presence of atypical cells and signet-ring cells, positive staining for mucin and positive immunohistochemical stainings for keratins, carcinoembryonic antigen(CEA), and lysozyme within the tumor cells infiltrated in the irregular, intertwining bundles of collagen in the reticular dermis.
