title: [Extremely rapid progression of oral cavity carcinosarcoma].
abstract: BACKGROUND
  Carcinosarcoma is a very rare malignant tumor of the salivary glands including accessory salivary gland, associating malignant mesenchymal and epithelial tissue. It usually occurs after 50 years of age. Its prognosis is very poor. We present a case of carcinosarcoma having evolved extremely rapidly.
  
  
  METHODS
  A 38-year-old female patient presented with an inflammatory budding lesion of the mandibular gingival mucosa. The diagnosis of carcinosarcoma having developed from an accessory salivary gland was made after testing biopsies. The carcinosarcoma could not be removed because of an extremely rapid tumor growth, its volume having increased three fold in 2 weeks. The patient died in a few weeks.
  
  
  CONCLUSIONS
  The occurrence of carcinosarcoma at 38 years of age is exceptionally rare. The rapidly evolution of carcinosarcoma is well documented. It may prevent complete excision. This case led us to suggest an emergency management for carcinosarcomas.
