As children with cancer survive longer, the incidence of second malignant neoplasms has increased considerably. We describe here three cases of second solid tumors after 12, 8 and 2 years of initial diagnosis of cancer: one osteosarcoma of left maxilla in a previously treated child with bilateral retinoblastoma, a temporal astrocytoma associated with acute lymphoblastic leukemia and a glioblastoma multiforme in a girl with neurofibromatosis de Von Recklinghausen, after Non Hodgkin lymphoma, respectively. We review the literature about the influence of genetic, immunologic and therapeutic factors involved in the appearance of these second tumors.

A case of familial hemophagocytic limphohistiocytosis (FHLH) is presented in a 16 months old infant, with clinical picture of prolonged fever, cutaneous purpura, generalized lymphadenopathy and progressive hepatosplenomegaly and laboratory of severe pancytopenia, hypofibrinogenemia and hypertriglyceridemia, with elevation of the pre-beta fraction in the lipidogram, all this compatible with this disease. She also showed bone marrow and ganglionar biopsy infiltrated by histiocytic cells with hemophagocytosis. The patient received chemotherapy with cycles VP-16, vincristine (VCR) and intrathecal methotrexate (MTX), alternating every two-three weeks with VACP, during one year, with resolution of clinical and laboratory parameters after two months of this treatment without relapses. The survival from diagnosis is 39 months.
The authors review 133 cases of idiopathic thrombocytopenic purpura (ITP), through 17 years of follow-up in children from 2 months to 13 years of age. The clinical presentation of hemorrhagic signs, laboratory findings and different treatments employed are analyzed with special reference to recent treatment of these children.
