NEVES, Frederico Sampaio et al. Adenoid cystic carcinoma in an uncommon site. Rev. cir. traumatol. buco-maxilo-fac. [online]. 2010, vol.10, n.4, pp. 17-20. ISSN 1808-5210.

The adenoid cystic carcinoma is a slow growing and painless mass, with a tendency to invade peripheral nerves and produce metastasis, and also presenting a high rate of recurrence. Adenoid cystic carcinoma is relatively rare condition, accounting for 10% to 15% of all major salivary gland neoplasms and approximately 12.3% of minor salivary glands neoplasms. The tongue is involved in 19.8% of the cases, and in 85% of these cases the affected region is the base of the tongue. We report a case of adenoid cystic carcinoma in a 66-year-olf female patient, located in the dorsum of the tongue, and describe its ultrasound characteristics.
