Abstract
An 86- year- old man, had undergone gastric surgery for peptic ulcer disease 40 years ago and he was diagnosed with gastric adenocarcinoma. Then he underwent a subtotal gastrectomy with regional lymphadenectomy, followed by Roux en Y gastrojejunostomy, and adjuvant chemotherapy. One and a half years later, the patient presented with a solid mass on his abdominal wall. Complete excision of the mass revealed a moderately differentiated adenocarcinoma consistent with the primary tumor of the stomach followed by fluorodeoxyglucose positron emission tomography (FDG PET) scan that showed hypermetabolic activity in the liver and the para-aortic lymph nodes, suggestive of distant metastasis.

Summary
Gastric cancer is the fifth most common cancer worldwide but the third leading cause of cancer related deaths according to the World Health Organization (WHO). Gastric cancer usually gives metastasis to the liver, peritoneal cavity and lymph nodes and rarely to the skin [1]. We are reporting a rare case of skin metastasis of gastric cancer in an 86-year-old male, first case reported in Lebanon This is a case of an 86-year-old man, nonsmoker, nonalcoholic, with no known food and drug allergy, had undergone gastric surgery for peptic ulcer disease 40 years ago. The patient was started on adjuvant chemotherapy: Capecitabine per os twice daily He was followed up at 1, 3, 6 and 12 months with serial CT scan and serum tumor markers that revealed no local or distant recurrence. The mass was excised, and the histology revealed a metastatic deposit of a moderately differentiated adenocarcinoma consistent with the known primary gastric tumor (Figure 3).
