Paraneoplastic Auto-immune Hemolytic Anemia: An Unusual Sequela of Enteric Duplication Cyst.

Enteric duplication (ED) cysts are rare congenital anomalies of the alimentary canal that present in childhood. Although benign in most case, ED cysts have the potential to cause complications including a rare association with secondary carcinomas. Autoimmune hemolytic anemia presenting as a paraneoplastic syndrome secondary to solid tumors is an unusual phenomenon. Here we report a patient case with ED cyst described in association with intestinal adenocarcinoma and warm-auto immune hemolytic anemia, with resolution of the hemolysis upon its surgical resection.
