A rare case of extra-parotid pleomorphic adenoma

Abstract

A 56-year-old male patient presented to the Department of Otolaryngology with a gradually enlarging soft palatal mass on the right side over several months. Clinical examination revealed a non-ulcerated, dome-shaped, palatal swelling on the soft palate. The mass, measuring approximately 2x2 cm, was smooth, uninodular, firm, non-tender, and non-fluctuant, without involvement of adjacent teeth. No overlying ulceration or discoloration was observed. Computed tomography scan indicated a well-circumscribed solid lesion (2.3 x 1.9 x 1.7 cm) with no evidence of infiltration into surrounding soft-tissue structures, the pterygopalatine fossa, or palatine nerve foramina (Figure 1, arrow). The lesion was successfully resected through a transoral approach, easily dissected from surrounding tissue, and sparing the overlying mucosa (Figure 2). Pathological analysis confirmed a diagnosis of pleomorphic adenoma. The patient recovered well, and subsequent follow-up in the outpatient department revealed no signs of recurrent tumor.
