Summary
Epithelial-myoepithelial carcinoma (EMEC) is a very rare low-grade malignancy with an incidence of less than 1% of all salivary gland tumors. In the parapharyngeal space, it can arise either from the deep lobe of the parotid gland or from minor salivary glands of the oropharynx. We present a case of a 70-year-old female patient with progressive dysphagia and a bulging of paratonsillar space. A CT scan revealed a cystic formation in the parapharyngeal space and bilateral inhomogeneous tumors in parotid glands. Preoperative FNAB (fine needle aspiration biopsy) was undiagnostic. Definitive histologic examination after surgical removal confirmed epithelial-myoepithelial carcinoma in the parapharyngeal space and Warthin’s tumors in both parotid glands. Immunohistochemical tests of the EMEC revealed BRAF, COSM476 a COSM775 and PIK3CA mutations, however, no HRAS mutation was detected. This case report shows a rare clinical and radiological presentation that could resemble benign diagnosis. Multiple salivary gland tumors are relatively rare conditions. Warthin’s tumor is the most common tumor with this type of behaviour. The coincidence of bilateral Warthin’s tumor of parotid glands with a parapharyngeal epithelial-myoepithelial carcinoma has not been documented in literature so far.
