| Popis: | The antrochoanal polyp, also called Killian polyp, represents around 4% to 6% of all nasal polyps with a higher incidence in children and young adults. It is a benign lesion that grows from the mucosa of the maxillary sinus and reaches the choana. A 34-year-old male patient attended the surgical service to remove a mesiodens. No noteworthy changes were observed at the intraoral examination. Computed tomography evidenced a well-circumscribed and delimited hypodense mass in the left maxillary sinus. An excisional biopsy was performed, and histopathologic analysis revealed the presence of a loose, edematous connective tissue with thin lines consisting of collagen fibers, congested vessels, and a discrete presence of lymphocytes and plasma cells. Another region exhibited a peduncle composed of connective tissue and the presence of ciliated pseudocolumnar epithelium. The diagnosis of a Killian polyp was established. The patient is under follow-up for 4 months without signs of relapse. |
