Hamartoma of the Nasal Vestibule: Case Report and Review of Literature.

Respiratory epithelial adenomatoid hamartoma (REAH) represents a category of tumor-like lesion arising from congenital developmental anomalies, characterized by aberrant differentiation or maturational arrest of multiple tissue lineages during embryogenesis. The predominant anatomical site involves the nasal cavity, specifically the nasal septum, with additional potential locations including the middle meatus and ethmoidal sinuses. Definitive diagnosis generally requires histopathological examination. These uncommon nasal neoplasms are amenable to complete excision through endoscopic surgical approaches performed under general anesthesia. A 55-year-old patient with nasal vestibular REAH presented with nasal obstruction, intermittent nasal pruritus, and diminished olfactory function. Clinical examination detected an ovoid mass in the right nasal vestibule, while radiological imaging demonstrated soft tissue density in the corresponding area. The diagnosis of REAH was confirmed through histopathological assessment after complete surgical excision. The patient fortunately experienced no procedure-related complications throughout the perioperative course and follow-up period. Postoperative surveillance through scheduled follow-up examinations is essential to prevent local recurrence.
