Para-pharyngeal space (PPS) tumors include an heterogeneous group of neoplasms, accounting for approximatively 0.5–1.5% of all head and neck tumors. Management of these neoplasms requires a careful diagnostic workout and an appropriate surgical approach to obtain good outcomes associated with minimal aesthetic drawbacks. In this study we investigat...

... space tumors are rare, accounting for approximatively 0,5/1,5% of all head and neck neoplasms [1][2][3][4][15][16][17]. The diagnosis and management of these tumors are often a big challenge [18][19][20][21][22][23][24] due to their deep location in a complex PPS anatomy (Figure 2), proximity with nervous and vascular structures, histological subtypes [6][7][8][9]. In our Serie of the 50 men and 48 female who underwent surgery, 71% had benign neoplasms and 29% malignant tumors. ...

(3,4) The most common tumors of the PPS are benign tumors such as pleomorphic adenomas of the salivary gland, followed by paragangliomas and neurogenic tumors.

Parapharyngeal space (PPS) tumors are among the most challenging tumors of the head and neck region to diagnose and treat. Acinic cell carcinoma (ACC) is an extremely rare extra-parotid malignant neoplasm of the PPS. Herewith, we report a case of extra-parotid, low-grade solid pattern ACC diagnosed in a 55-year-old male who presented with a left parapharyngeal bulge. Despite its rare occurrence, ACC of the PPS should be included in the differential diagnosis of PPS tumors.
