Giant neck neoplasm. Case report.

Giant latero-cervical neoplasias usually originate in the parotid gland, as slow-growing adenomas, in subjects who take little care of their personal health. Giant adenomas of submandibular gland are very rare. These neoplasias involve prevalently male sex (male/female ratio: 2/1) and usually occur between 20 and 40 years of age. Signs of malignant transformation may be observed in the adenomatous epithelial component in a percentage ranging from 1% to 10% of cases. The case is reported of a giant malignant latero-cervical neoplasia originating from a pleomorph adenoma of the submandibular gland. The diagnostic work-up and treatment protocol are described.
