title: [Desmoid tumor of the parotid gland].
abstract: BACKGROUND
  Desmoid tumor is a benign microscopic tumor that belongs to the group of the deep fibromatosis. It usually arises from facial or musculoaponeurotic structures in the abdomen but rarely is located in the head or neck. Locally, it is characterized by a massive invasion with strong potential for recurrence.
  
  
  METHODS
  A 37-year-old woman was hospitalized for a swelling of the left parotid gland region which had progressed for eight years. Physical examination revealed a tumor in the parotid gland, which was hard and adherent deeply, measuring 4 cm/3 cm and sensitive to palpation; without satellite nodes nor facial paralysis. The treatment consisted in a superficial parotidectomy. Pathology was in favor of a desmoid tumor. After an 18-month follow-up, the patient is healthy without any sign of recurrence.
  
  
  CONCLUSIONS
  Desmoid tumors are deep fibromatosis characterized by their slow growth and especially by considerable infiltration of the adjacent structures but without potential for metastasis. Although very rare, the cervical localizations are especially aggressive. This clinical case illustrates the clinical features of this rare affection and offers matter for discussion of therapeutic difficulties.
