title: Detection of TLS/FUS-CHOP fusion transcripts in a case of oral liposarcoma.
abstract: OBJECTIVE
  The aim of this study was to detect the chromosomal translocation t(12;16)(q13;p11) that leads to a gene fusion encoding a FUS-CHOP chimeric protein and has been shown to be highly characteristic of myxoid and round cell subtypes of liposarcoma, in a case of oral myxoid liposarcoma.
  
  
  METHODS
  Nested reverse transcriptase-polymerase chain reaction to detect the TLS/FUS-CHOP fusion gene transcript was performed. A case of inflammatory fibrous hyperplasia and a case of oral lipoma were included as negative controls.
  
  
  RESULTS
  Only the myxoid oral liposarcoma showed a 103-base pair product, specific of TLS/FUS-CHOP fusion type II transcript.
  
  
  CONCLUSIONS
  The identification of FUS-CHOP transcript is potentially useful in the diagnosis and research of oral liposarcomas.
