Intestinal type of adenocarcinoma of nose and pare nasal sinuses is the second most common type of sino-nasal adenocarcinoma. It is mostly composed of growth patterns which resemble adenomas or carcinomas of intestinal origin. Intestinal type of adenocarcinoma (ITAC) occur mostly in males with age group of 50 to 64 years. It is most often localised in Ethmoid Sinuses, followed by nasal cavity and maxillary sinus. Overall incidence is less than 1% of all neoplasm and 1.4% nasal region. ITAC is frequently seen in wood workers. ITAC associated with wood dust exposure occur predominantly in ethmoid sinus but sporadic cases arise in maxillary Antrum. ITACs are aggressive malignancies, it may spread to orbit, pterygo-palatine fossa, infra temporal fossa and cranial cavity. We report a case of sino-nasal adenocarcinoma in 40 year old male, non wood worker.

Method: A 40 year old, male, clerk by occupation,with complaints of bleeding from left nose, left side nose obstruction and heaviness of head for 2 years. Anterior rhinos copy was done which shows a mass in left nasal cavity which was reddish-blue in colour, bleeds on touch, soft in consistency, non tender.

Results: Xray PNS and CECT PNS was suggestive of mass in left maxillary antrum and left nasal cavity. Biopsy came out to be inflammatory polyp. so micro deb-rider assisted FESS was done and tissue sent for histological examination. Biopsy shows intestinal type of sino-nasal adenocarcinoma. CECT Abdomen was normal. 25 cycles of Radiotherapy was given to thee patient.

Conclusion: Intestinal type adenocarcinoma are a rare malignancy of the nasal cavity and paranasal sinuses. Its association with occupational exposure to wood dust has been well documented, but sporadic cases have been reported. Treatment consists of surgery, radiation or both.
