Recurring anterior facial swelling.

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.
