Hepatitis C Virus (HCV) is a cause of secondary chronic immune thrombocytopenic purpura (ITP). We report a 43 year old man with mild Hemophilia A, who received blood transfusions during childhood, that consulted for epistaxis and ecchymoses. The laboratory showed a platelet count of 23.000/mm3, positive HCV serology and elevated transaminases. Steroids administered in pulses followed by oral doses resulted in a partial response requiring a second pulse and association of azathioprine. A steroidal diabetes appeared. Given his refractoriness, splenectomy and liver biopsy were performed. He continued on azathioprine maintaining a platelet count near 50.000/mm3 but continued with bleeding episodes. Liver biopsy showed a chronic active hepatitis.

Thyroid lymphoma represents less than 1% of malignant thyroid tumors and its diagnosis is difficult. We report a 25 years old woman, admitted with the diagnosis of diffuse euthyroid goiter and thyroid cancer. She was subjected to a subtotal thyroidectomy and the pathological study of the surgical piece showed a Hodgkin lymphoma, subtype nodular sclerosis. The patient was treated with three cycles of chemotherapy, using cyclophosphamide, vincristine, procarbazine, prednisone, doxorubicin, bleomycin, vinblastin and radiotherapy. She refused to continue treatment after the third cycle and after 3 years and 5 months of follow up, is well and free of disease (Rev Med Chile 2000; 128: 783-6).

Invasive fungal infections are an increasingly common problem in patients with cancer and other vulnerable groups. We report a case of hepatosplenic hialohifomycosis probably by Aspergillus sp. In a patient with acute leukemia, and prolonged neutropenia, treated with corticosteroids and broad spectrum antibiotics. A review concerning diagnosis, clinical course and treatment of this condition is presented. (Rev Med Chile 2000; 128: 641-6).
