Autoimmune hemolytic anemia (AIHA) is a rare condition in children which differs from the adult form. It is defined by immune-mediated destruction of red blood cells caused by autoantibodies. Treatment depends on the type of AIHA, its severity and whether there is an underlying disorder. Rituximab is now the preferred second-line treatment for primary warm autoimmune hemolytic anemia (Waiha). Here, we present a 2-monthboy with wAIHA, resistant to steroids and cyclosporin A, who was successfully treated with rituximab. Our patient is one of the youngest cases in the literature.

Background: Ewing sarcoma (ES) is a rare malignancy, most commonly presenting as a bone tumor, histologically characterized by sheets of poorly differentiated cells with small, blue, round nuclei and scant cytoplasm. Ewing sarcoma that may originate from bone or soft tissue has an increased tendency to involve the axial skeleton, particularly the pelvis. Case Report: We presented a case of Ewing sarcoma originated from pubis bone, who was underwent percutaneous nephrostomy due to external pressure on the bladder and ureter. Conclusion: We recommend placing optimal drainage, to each obstructed renal unit so treatment can be started as soon as possible
