Infantile (desmoid-type) fibromatosis of the parotid gland.

Infantile fibromatosis, one of the fibrous tumours of infancy and childhood, is a fibroproliferative lesion characterized by aggressive local invasion without any tendency to metastasize, the absence of cytological evidence of malignancy and a high rate of local recurrence when incompletely excised. We report a case of infantile (desmoid-type) fibomatosis in a seven-year-old girl arising from the deep lobe of the parotid gland that was treated by complete surgical excision with preservation of the facial nerve. The clinical features, pathology and treatment are briefly discussed.
