RESUMO
Autoimmune hemolytic anemia is a type of hemolytic anemia characterized by autoantibodies directed against red blood cells shortening their survival. When autoimmune hemolytic anemia is secondary to a paraneoplastic process, severe anemia can occur leading to significant morbidity and even mortality. Here we discuss the literature and present the case of a child with autoimmune hemolytic anemia from a paraneoplastic syndrome secondary to a renal tumor.

Gastric duplication cysts are a rare finding in the adult population. Duplication cysts comprise 4% of the alimentary tract duplications, and about 67% are usually discovered within the first year of life. They can be located anywhere in the gastrointestinal tract, with the majority located in the greater curvature of the stomach. Duplication cysts may be identified on imaging studies in asymptomatic patients or may present with nonspecific symptoms that can include emesis and abdominal pain. We describe a case of a communicating cyst in the antrum of the stomach leading to gastric outlet obstruction in a 19-year-old male.
