Heterotopic pleomorphic adenoma in the postauricular area.

Heterotopic salivary gland tissue is salivary tissue located outside the sites generally known to accommodate major and minor salivary glands. Although heterotopic salivary tumors were reported in various regions of the head and neck, they are seldom found in the superio-posterior neck region and can be confused with other neck masses. Herein, we present a rare case of a heterotopic pleomorphic adenoma in the postauricular area and remind clinicians that heterotopic salivary tumors should be in the differential diagnosis of neck masses.
