Rare presenting features of carcinoma of stomach – Leptomeningeal carcinomatosis, breast metastasis, malignant pleural effusion, and dermatoses: A report of two cases and review of literature

Abstract

Gastric cancer can have protean manifestations, usual symptoms mimicking those of peptic ulcer disease. Gastric adenocarcinomas have rarely been reported with leptomeningeal carcinomatosis (LMC) and dermatoses as initial presenting features. It is also difficult to diagnose breast metastasis of gastric carcinoma due to its rarity. We report two such cases with rare initial presentation. Our first case was a 46-year-old male who presented with LMC. Our second case was a 24-year-old male whose initial complaints were shortness of breath, bilateral breast lumps, and skin discoloration. Both cases on further investigations were found to have primary tumors in the stomach.
