Abstract
Schwannomas are benign peripheral nerve sheath tumors most frequently found in the head and neck region. Their occurrence in the nasolabial area, however, is exceedingly rare. We reported this case, a 27-year-old man presenting with a gradually enlarging right-sided nasal swelling causing progressive obstruction. Clinical examination revealed a firm, non-tender mass at the anterior nasal floor. The lesion was excised via a sub-labial approach, and histopathological analysis confirmed the diagnosis of schwannoma. Given the rarity of nasolabial schwannomas, they should be considered among differential diagnoses of nasal masses. Complete surgical excision through a sub-labial approach remains the preferred management, offering both diagnostic confirmation and curative treatment. Post operatively patient experiencing improvement in nasal blockage and recovered well with complete excision of mass with no sign of recurrence seen on follow up.
