Abstract

Primary intraosseous adenoid cystic carcinoma (PIACC) of mandible is a rare malignant tumour of the salivary tissue with only 47 cases being reported in the literature. This article reports a case of PIACC in a 34 year old male patient in left mandibular region presenting as an irregular lytic expansile lesion on Computer tomography. Microscopic examination of the lesion showed basaloid cells arranged mostly in solid islands with few cribriform areas suggesting solid subtype of intraosseous adenoid cystic carcinoma. Solid growth pattern of the tumour indicates poor prognosis, thus warranting regular follow up of the patient. This case implies the importance of considering malignant salivary gland tumors in the differential diagnosis of poorly defined radiolucencies of the mandible. Early detection of such lesions will benefit the patient and reduces the associated mortality and co-morbidity.
