Exceptional Variant with Distant Cutaneous Metastasis as the First Clinical Sign in Gastric Signet-Ring Carcinoma.

OBJECTIVE Skin metastases from gastric cancer are rare and usually occur very late in the course of the disease. The most common metastatic sites liver, the peritoneal surfaces, and the non regional or distant lymph nodes. CASE REPORT In this case we report the short-term survival of a 67-year-old man complined of multiple nodular lesions in various part of his skin. Histology showed a metastatic signet ring cell adenocarsinoma. Esophagogastroduodenoscopy was performed and a crater- like ulcer, about 3 cm in diameter, was observed on the anterior part of the stomach corpus distal. A biopsy specimen was obtained, and histopathological findings were consistent with gastric signet-ring cell carcinoma. XELOX chemotherapy regimen was initiated for the patient. CONCLUSION Skin metastasis of gastric adenocarcinoma is a rare condition with a poor prognosis. It may be the first manifestation of a clinically silent visceral cancer or may represent a recurrence of an internal malignancy.
