ХОНДРО-КОСТНАЯ РЕСПИРАТОРНАЯ ЭПИТЕЛИАЛЬНАЯ АДЕНОМАТОИДНАЯ ГАМАРТОМА

Abstract

Hamartomas of sinonasal tract are a very rare and poorly studied phenomenon, even within the framework of world medicine. In the classification of tumors of the head and neck according to the WHO, in the section of nasal papillomas, only respiratory epithelial adenomatoid hamartoma is mentioned, there is no information about the other types of nasal hamartomas. The peculiarity of this clinical case is the difficulty in verifying the type of hamartoma of the sinonasal tract (respiratory epithelial adenomatoid, seromucinous, chondromesenchymal or chondro-osseous respiratory epithelial adenomatoid), respectively, and in determining the tactics of subsequent treatment, due to the rarity of this type in the world and the possibility of malignant transformation. A 15-year-old patient was diagnosed with chondro-osseous respiratory epithelial adenomatoid hamartoma. According to the literature, only 12 such clinical cases were recorded in the world. The absence of specific radiological and laboratory markers, the clinical picture of the disease similar to other diseases of the nose and paranasal sinuses - all this complicates early diagnosis, and emphasizes the need to include this type of neoplasm in the differential diagnostic range in children and adults with masses of the nasal cavity.
