[Paraneoplastic hemolytic anemia associated with prostate cancer. A case report].

Paraneoplastic syndromes are a group of tumor-related symptoms not directly attributable to tumors or metastasis. Symptoms are caused by secretion of substances by the tumor or the production of antibodies from immune cross-reactivity between tumor and normal tissues. Among hematological paraneoplastic syndromes, cancer-associated hemolytic anemias associated are rare, particularly in solid tumors.
