title: [Pseudoangiomatous spindle cell lipoma: about six cases].
abstract: OBJECTIVE
  Pseudoangiomatous spindle cell lipoma (PASCL) is a rare variant of spindle cell lipoma. Nine cases have been previously described in the literature. In this retrospective study, we report six cases reviewed in the department of pathology at the Bergonié Institute between 01/01/1987 and 31/12/2009.
  
  
  METHODS
  Clinical and histological data were reviewed. A standard histological study was realized and immunochemistry was performed with smooth muscle actin (SMA), desmin, epithelial membran antigen (EMA), S 100 protein, CD34, CD31, MDM2, CDK4.
  
  
  RESULTS
  All patients were male and median age was 52. Median size was 3cm. We report four atypical locations: cheek, finger, elbow and jaw.
  
  
  CONCLUSIONS
  In our series, the frequency of PASCL was 1,25% of all spindle cell lipomas. Histological and immunohistochemical aspects are identical to those observed in the literature.
  
  
  CONCLUSIONS
  The pattern of PASCL is typical, particularly with the positivity of CD34, which is stronly suggestive of diagnosis.
