RÉSUMÉ
Cutaneous metastases from gastric carcinoma are uncommon. The frequency of metastses to the skin from gastric carcinoma have ranged from 0.3% to 0.4%. Carcinoma en cuirasse, first described by Velpeau in 1838, is marked sclerodermatous change and characterized by a difffuse morphea-like induration of the skin and represents a rare manifestations of breast carcinoma metastatic to the chest wall. It is vary rarely seen in lung, stomach, kidney and other metastasizing malignancies. We report a case of carcinoma en cuirase and nodular carcinoma from gastric carcinoma in a 36-year-old male who complained chiefly of multiple cutaneous nodules. He had mixed lesions of an erythematous morphea-like induration on the neck and multiple erythematous nodules on the chest and abdomen. Gastroscopy finding showed a Borrmann type IV advanced gastric carcinoma. Histopathologic examination of skin and stomach showed atypical cells with pleomorpic, hyperchromatic nuclei and scanty, eosinophilic cytoplasm, which are consistent with poorly differentiated adenocarcinoma. Immunohistochemical stainings showed positive reaction for cytokeratin. He died three months after the appearance of cutaneous lesions.
