Nasal dermoid cyst

A rare otorhinolaryngological malformation characterized by a dermoid cyst along the nasal dorsum or glabella, lined by keratinized squamous epithelium and containing intraluminal keratin and mature adnexal structures, such as hair follicles, sebaceous and sweat glands. The majority of nasal dermoid cysts are superficial, rarely they extend intracranially. The cysts are typically benign but are susceptible to recurrent infections that may progress to osteomyelitis, meningitis or an intracranial abscess.
