A Rare Association of Mixed Autoimmune Hemolytic Anemia with Gastric Carcinoma

This case report outlines a 70-year-old female patient who presented with a concurrent mixed autoimmune hemolytic anemia (AIHA) and a gastric adenocarcinoma. Her treatment course of these two diseases is summarized, which included supportive care, neoadjuvant chemotherapy for her gastric adenocarcinoma, steroids, rituximab, and surgical resection of the tumor. This approach ultimately led to the stabilization of her AIHA and primary cure for her solid malignancy. We briefly review both AIHA and gastric adenocarcinoma as clinical entities, propose working causes of hemolytic anemia including gastric adenocarcinoma, and outline a successful treatment pathway for these two concurrent conditions.
