title: [Clinicopathologic features and treatment of primary splenic tumors].
abstract: OBJECTIVE
  To investigate the clinical pathological characteristics and treatment of primary splenic tumor.
  
  
  METHODS
  The clinical data of 43 patients with primary splenic rumors, 23 males and 20 females, aged 44.7 (19 - 66), treated in the Cancer Hospital, Chinese Academy of Medical Science from Feb 1972 through Mar 2006 were analyzed.
  
  
  RESULTS
  Of the 43 cases, 21 cases (48.8%) were found in physical examination. 42 cases underwent splenectomy and 1 case underwent rumor biopsy. Sixteen cases were with benign splenic tumors, including 15 cases of hemangioma and 1 case of lymphangioma. Of the 24 malignant cases, 16 suffered from splenic lymphoma and 8 from angiosarcoma. Most lymphoma cases survived and the mean three year surviving rate was 88.7%. The mean surviving time of angiosarcoma was only 10.4 months.
  
  
  CONCLUSIONS
  Primary splenic tumors lack specificity; B-ultrasonography and CT are primary examination methods. Surgery is an effective method in treatment of primary splenic tumors.
