Desmoid Tumor of The Parotid Gland

Desmoid tumor is a proliferation of a mesenchymal, fibroblastic or myofibroblastic tissue. It is a non-capsulated tumor. Despite of its benign nature, desmoids tumor have an aggressive behavior.Its localization in the parotid gland has been rarely reported in the literature.The particularity of this location in the head and neck is the proximity of Vascular-nervous structures, the facial nerve in the parotid location and the consequence, if affected, on the facial motility especially that this tumor often occur in young people. The clinical presentation is often about a slow-growing mass characterized by being: painless, ill defined, firm, non inflammatory, deeply located, and fixed to the underlying structures. Treatments strategies, made always within a multidisciplinary committee, are based on the biological natural behavior of this deep fibromatosis which is unpredictable and variable. Surgery could be undergone every time it is radical. Radiotherapy could also be played. But the most relevant point is that actually, most authors highlighted the conservative approach by the “wait and see” policy for primary as well as for recurrence of the disease after surgical resection or radiotherapy.
