A Rare Case of Mixed Tumor of Right Nasal Sill Diagnosed Histopathologically more Frequently than Expected

Abstract

Mixed tumor (MT) is an unusual, benign skin appendageal tumor, with an eccrine and apocrine origin, resembling mixed tumors of the salivary glands. Although it usually involves the head and neck region, the nasal region is a rare location. It develops as a slow-growing, small cutaneous mass. We report a rare case of mixed tumor in a 35-year-old female, who presented with a firm, asymptomatic mass in the right nasal sill, slowly growing for approximately 5 years. A provisional clinical diagnosis was made by fine needle aspiration cytology evaluation. The final diagnosis is confirmed by histopathological examination. This case highlights the importance of fine needle aspiration cytology in providing the essential clue to uncover the diagnosis and orient the surgical management of the patient. The excision and repair techniques require more skill and time, considering the location of the lesion.
