Abstract

There are a number of benign tumors of the nose and pharynx that are seldomly reported in literature but that can sometimes prove difficult to treat and extremely important for differential diagnosis. The present study presents cases of rare benign tumors localized in the pharynx, nasal and sinus cavities, as well as reviews of literature and historical references for each type of tumor. Unilateral nasal hemangioma in a 72‑year‑old male which, although not a rare pathology, raised problems due to auto‑resection of the tumor. The surgeon was able to pull it out with ease without bleeding; it is possible that the mass would have eventually fallen out. Pilomatrixoma is a relatively uncommon ectodermal benign tumor of the skin derived from hair matrix cells. Surgical resection is curative but recurrence is possible (≤5% risk). The presented case is of a 26‑year‑old female with a pilomatrixoma of the left cheek who, for aesthetic reasons, refused a classical external surgical approach. Trans‑oral resection was performed, which proved feasible but laborious and prone to recurrence. Inverted Schneiderian papilloma is a rare benign tumor of the nasal and sinus cavities with increased potential for invasion, recurrence and malignant transformation compared with other types of papilloma and other benign tumors of the area. The tumor represents 0.5‑4.0% of all nasal tumors and has been described under different names, such as villiform cancer and cylindrical/transitional papilloma. The present study reports a rare case of bilateral papilloma in a 68‑year‑old male. He presented with bilateral evolving nasal obstruction and hyposmia. Following surgery, the patient was treated by a multidisciplinary team and followed by a respiratory rehabilitation program.
