“…Moreover, once the lesion pedicle was identified, endoscopic-assisted surgery permitted us a minimal invasive excisional biopsy. As also reported by Roh et al [8], even in our experience we confirm that endoscopic surgery is effective to obtain the complete resection of benign nasopharyngeal tumors thus achieving surgical clear margins of resection with a low risk of injuries to the Eustachian tube. …”

Pleomorphic adenoma is the most common benign tumor of the parotid glands. Rarely it may arise from minor salivary glands of the upper aerodigestive tract. A 57-year-old woman was admitted at our institution presenting with nasal obstruction. Endoscopic evaluation revealed a pedicled mass in the rhinopharynx. After radiological examination, we opted for a transnasal endoscopic-assisted excision of the mass under general anaesthesia. Histological evaluation deponed for pleomorphic adenoma with clear surgical margins. No endoscopic evidence of local recurrence has been shown after 48 months of followup. In the literature, few cases of pleomorphic adenoma arising in the rhinopharynx have been reported. The introduction of endoscopy, as shown by our experience, leads to important benefits in the identification, treatment, and followup of such rhinopharyngeal benign tumors.

Pleomorphic adenoma (PA) is the most common benign tumor of the major and minor salivary glands, but rarely found in the nasopharynx. A PA originating from the left lateral wall of the nasopharynx was found in a 52-year-old female who presented with nasal obstruction, left-side otalgia, aural fullness, tinnitus and subjective hearing loss. It was successfully removed by transnasal endoscopic surgery (TES) and navigator system assessed our location, due to the proximity of critical anatomic structures such as the left internal carotid. We believe that the TES for primary and recurrent nasopharyngeal benign tumors is feasible and safe in properly selected patients, due to superior functional and cosmetic results and a low complication rate. Tumor characteristics and location should be taken into account when selecting cases for the right procedure for this lesions; transnasal endoscopic surgery is safe and preferable, carrying less potential morbidity compared to open procedures.

BackgroundThe benign tumors of nasopharynx are least encountered tumors in otolaryngology, as nasopharynx is considered one of notorious anatomical site for the malignant tumors. Pleomorphic adenoma of the minor salivary gland of nasopharynx and parapharyngeal space is rare. We present a pleomorphic adenoma of minor salivary gland which was mismanaged.Case presentationAn adult male presented with left nostril obstruction for five months. The examination found big mass extending from nasopharynx to oropharynx. On CT scan, this tumor was quite big and extending to the parapharyngeal space. The FNAB found it a carcinoma but it did not respond to radiotherapy. The excision biopsy of tumor revealed it as pleomorphic adenoma. We found only five published reports on this tumor arising from nasopharynx.Discussion and conclusionAlthough, in this case report exact origin of the tumor could not be ascertained as it also appeared to be a parapharyngeal tumor but we kept the possibility of a nasopharyngeal tumor on the basis of clinical features. The pleomorphic adenoma of nasopharynx is rare. It can be misdiagnosed as malignant epithelial tumor on histopathology. The differentiation from its malignant variant is also difficult. A possibility of benign tumor should always be kept in nasopharyngeal growth with no evidence of metastasis, and histopathological diagnosis of growth should be available before any definitive treatment.
