Abstract

Adenoid cystic carcinoma is a relatively rare tumor of epithelial cell origin, most commonly arising from major or minor salivary glands, and comprises 3 to 5% of all head and neck malignant tumors. The peak incidence is from the fourth decade to the sixth decade, occurring slightly more in females. It usually presents as a slowly growing, firm mass, and patients most commonly report a constant, low-grade dull ache that gradually worsens in severity. Here we reported a 55 years old female presented with complaints of left nasal block, left sided headache aggravated on cold food for 6 months. Local examination of the nasal cavity revealed normal external framework and septum showed mild DNS to the left with spur. Anterior rhinoscopy- DNS to left with spur. Posterior rhinoscopy showed left nasal mass. CT paranasal sinuses showed a polypoidal lesion mildly enhancing irregular soft tissue density involving the left nasal cavity with erosion/resorption of adjacent bones – likely to be malignant neoplastic etiology. On histopathological examination features suggested Adenoid cystic carcinoma. Hence we presented this case report due to it’s site rarity.
