[Inverted papilloma of the nasal cavity - a case report]

Inverted papilloma is a rare, benign sinonasal tumor. Its etiology is the most likely related to HPV infection. Inverted papilloma originates from the ciliated respiratory epithelium, typically from the lateral nasal wall. The tumor is characterized by endophytic growth inwards the stroma with adjacent tissues destruction. The clinical symptoms are non-specific, such as: unilateral obstruction of the nasal duct, rhinorrhoea, epistaxis and anosmia. The treatment consists in a complete surgical excision of the tumor. Inverted papilloma has a tendency to recurrence with incomplete resection and a potential to malignant transformation to squamous cell carcinoma. This manuscript presents a case of a young woman who suffered from recurrent epistaxis from ulceration of the mucous of the anterior part of the nasal septum. The patient in the interview had indicated the symptoms since six months and unsuccessful treatment with cetirizine. The woman was qualified to a surgical removal of the lesion with a transnasal approach. The histopahtological examination of the sample revealed Papilloma inversum. One-year follow up did not disclose the recurrence of the tumor.
