Malignant fibrous histiocytoma is a pleomorphic sarcoma in adults, which occurs principally as a mass on an extremity or in the abdominal cavity or retroperitoneum. It typically involved deep fascia or skeletal muscle and only rarely was confined to the subcutis without fascial involvement. Malignant fibrous histiocytomas developed in the intraabdominal organs are very rare and only few cases have been reported until now. Here, we report a case of malignant fibrous histiocytomar developed in the stomach of a 46-year old male who showed clinical and histologic features of malignant fibrous histiocytoma without any identified etiologic factors. The patient was treated successfully with surgery, and has had no recurrence since, during the ensuring one and a half yars.

Spontaneous hemorrhage in the patients undergoing hemodialysis is the ralatively common problem, but spontaneous mediastinal hemorrhage in such patients reported only few cases. We experienced a case of spontaneous mediastinal hemorrhage in chronic hemodialysis patient who complained of continuous pleuritic chest pain and mild dyspnea. The diagnosis was made dy chest computed tomography,magnetic resonance imaging and percutaneous fine needle aspiration of liquified dark reddish old blood material guided by ultrasonography. Treatment is usually conservative, with blood volume replacement and intensive hemodialysis using regional heparinization. We report on a patient undergoing hemodialysis due to endstage renal disease who developed spontaneous mediastinal hemorrhage.

Although a pathogenic mechanism of hemolytic anemia complicated with viral hepatitis is unknown, it is suggested that there are four mechanisms; 1) In the individual who has predisposition to hemolytic anemia, viral infection accelerates the red cell destruction & hemolysis become obvious. 2) Directly, virus itself injures to the red cell membrane. 3) The serious liver failure & hypersplenism induce the hemolysis. 4) Autoimmune hemolytic anemia because of immunological abnormality caused by viral infection. We experienced a case of autoimmune hemolytic anemia in 33-year-old male patient who was diagnosed as chronic lobular hepatitis B with biopsy. Diagnosis was estabilished by clinical features, blood cell count, routine urinalysis, direct & indirect Coombs test, liver function test, immunoglobulin quantitations, hepatitis B marker, bone marrow aspiration, and liver biopsy. This case was treated with corticosteroid and transfusion. During follow-up, he has been well tolerated.
