Ruptured Nasolabial Cyst, A Rare Cause of Epistaxis: A case report

The nasolabial cyst is an uncommon soft tissue lesion occurred anterior to maxilla on floor of the nasal vestibule. It is relatively common in female adults, mostly presents as a cosmetic concern due to bulging of the nasolabial fold as well as nasal blockage and pain in some cases. Epistaxis was not previously reported as a symptom of nasolabial cyst. In this article, we present a case of a long standing nasolabial cyst in a young boy presented with epistaxis. A 13-years old boy presented to ENT OPD of Nangarhar University Teaching Hospital with active nasal bleeding. The patient complained of a bulge below right side of the nose above the upper lip for the last four years increased gradually, associated with nasal blockage for the last one year and accompanied by intermittent nasal bleeding for the last 3 months with no history of trauma. There was marked asymmetry of the face with a blood clot in the right nostril. On anterior rhinoscopy, after cleaning the nose, a soft mass was seen in right nasal vestibule ruptured at its center extending to maxillary region at the level of nasolabial fold through a track associated with corresponding bulge on the same sided gengivobuccal sulcus. A soft tissue density mass lesion seen on right sided alar region on CT scan without ant bony involvement. The patient underwent surgical excision of the mass through a sublabial incision. The diagnosis was confirmed by histopathology. No recurrence was noted after 6 months of treatment. In light of literature review and the current case report we conclude that the patients with nasolabial cyst presents with facial deformity and nasal blockage, but long standing cysts can be presented with nasal bleed.
