Abstract:
The nasolabial cyst was first reported in 1882. The most common clinical finding of the nasolabial cyst is that of an asymptomatic soft tissue swelling involving the canine fossa/nasal alar base region. The pathogenesis is controversial, but this cystic lesion most likely develops from the nasolacrimal duct. Microscopically, this cystic structure is composed of a fibrous capsule with an unremarkable layer of pseudostratified columnar epithelium. The treatment of choice is surgical excision, after which recurrence is rare.
