    Abstract:
    Solitary fibrous tumor (SFT) is a rare neoplasm, arising in the adult and more commonly in the pleura. For many years it has been referred to the serous surfaces of the body, namely pleura, peritoneum and pericardium; recently cases arising in mesenchymal organs such as lung, mediastinum, liver and paranasal sinuses were reported. We present a SFT of the nasopharynx, observed in a 41 year-old patient complaining a 6 months history of aural fullness at the right ear. Clinical examination revealed the presence of secretory otitis media and swelling of the lateral wall of the nasopharynx. CT scan and MR showed the presence of a solid mass, with scarce vascularization, extending from the right side of the nasopharynx to the infratemporal and pterigoid fossae. The surgical approach consisted in a facial translocation by the rotation of a maxillary-check flap through different osteotomies; a firm whitish mass not invading the surrounding tissues was identified and enucleated. A definitive diagnosis cannot be made at frozen sections, requiring more accurate processing and immunohistochemical staining. Literature reports fourteen cases of SFT of the upper aero-digestive tracts (nasopharynx, paranasal sinuses, larynx) and some 8 more cases in the head and neck area (thyroid, salivary glands and parapharyngeal spaces). This case report adds a further contribution to support the mesenchymal origin of the SFT.
