Adenoid Cystic Carcinoma of Para-nasal Sinuses

Adenoid cystic carcinoma (ACC) is an uncommon tumour usually arise in the head and neck region mainly in the salivary gland and rare in the nose and para-nasal sinuses (PNS). We report a rare case of 35-year-old male with ACC of PNS who presented with nasal obstruction and nasal discharge. The CT PNS and orbits show illdefined minimally enhancing soft tissue density lesion extending into buccinators fossa, PNS, nasal cavity with adjacent bony destruction. Surgical incision was done and biopsy revealed ACC. Radiotherapy was given and regular follow-up done. The ACC of sinonasal cavities has poor prognosis, high recurrence due to peri-neural invasion. Multimodality treatment is the mainstay of ACC
