Nasal dermoid is a rare developmental anomaly arising from a cluster of epithelium trapped during the embryological development or failure of obliteration of the ectodermal extension. Progressive enlargement can lead to soft tissue or skeletal deformity or intracranial complications such as meningitis or abscess. Timely diagnosis and complete surgical excision are essential to avoid complications. We describe a 23 year old male presenting with nasal dermoid.

A 23-year-old male presented with a gradually increasing swelling on the root of the nose for 8 months. On examination, a firm 2 cm × 2 cm cystic swelling was seen at the root of the nose [Figure 1], and the rest of physical examination was normal. A provisional diagnosis of dermoid cyst was made. Magnetic resonance imaging (MRI) scan [Figure 2] was done to look for intracranial extension, but none was found. The patient underwent excision of the cyst, and postoperative biopsy was confirmatory [Figure 3]. He is asymptomatic at 1 year of follow-up. | Figure 2: Axial T1 magnetic resonance image showing a hyperintense lesion

Discussion | |  |
Nasal dermoid is a rare developmental anomaly and was first described in 1817 by Cruveleir.[1] It arises from a cluster of epithelium trapped during the embryological development or failure of obliteration of the ectodermal extension.[1] The incidence of nasal dermoids is 1 per 20.000-40,000 births and they account for 1-3% of all dermoids.[1],[2] The lesion can present as cyst, sinus, or fistula and may have an intracranial extension. Concomitant congenital anomalies such as absent third ventricle, spinal anomalies, preauricular sinuses, and midline facial defect such as cleft lip have been reported.[2] The presence of associated anomalies increases the likelihood of intracranial extension.
Progressive enlargement of the nasal dermoid can lead to soft tissue or skeletal deformity, local infection, or intracranial complications such as meningitis or abscess.[1] MRI is valuable for defining the intracranial as well as extracranial extent; however, the tract is better visualized by a computed tomographic scan.[3] Timely diagnosis and complete surgical excision are essential to avoid complications. The cyst can be locally excised; however, those with intracranial extension require a combined craniofacial approach.[1]
