| Popis: | Chondromesenchymal hamartoma (CMH) is a rare, benign lesion of the nasal cavity, paranasal sinuses, and skull base, composed of islands of hyaline cartilage in a myxoid background. The vast majority of CMH cases are infants and young children. According to the world literature, nasopharyngeal involvement of CMH is extremely rare. In all cases, the lesions were masses protruding from the nasal cavity or paranasal sinuses to the nasopharynx. We hereby report 2 adult male patients with masses completely situated in the nasopharyngeal space. In the first patient, the tumor originated from the posterior edge of the nasal septum and in the second one, from the posterolateral wall of the nasopharynx, adjacent to the pharyngeal orifice of the Eustachian tube. In both patients, the lesion was excised endoscopically, and histopathological analyses were consistent with a diagnosis of CMH. To our knowledge, those are the only cases of CMH completely situated in the nasopharynx. |
