AZUA-ROMEO, J. et al. Synchronous salivary gland tumors with regard to two cases. Rev Esp Cirug Oral y Maxilofac [online]. 2005, vol.27, n.3, pp.145-149. ISSN 2173-9161.

We present two new cases of synchronous tumors of the salivary gland. The first one refers to two benign tumors in the same parotid gland, while second one shows a benign lesion and a malignant tumor in two ipsilateral salivary glands. The appearance of synchronous multiple unilateral parotid tumors of different histologic types is extremely rare, accounting for less than 0.3%; this is usually a Warthin´s Tumor associated to other tumors. The current literature has been reviewed and 42 cases have been found entailing two different parotid tumors coexisting. Of these 11 referred to adenolymphoma associated with pleomorphic adenoma. Preoperative cytological diagnosis, as well as an exhaustive intraoperative inspection are the clues to discover nonidentified second tumors.
