ABSTRACT
A case of a 74-year-old male with unilateral nasal obstruction, recurrent epistaxis and a right intranasal mass is presented. It was initially diagnosed as hemangioma but final histopathology report revealed oncocytic carcinoma. Oncocytic carcinoma is a rare tumor of the salivary glands with very few reported cases, most of which involve the parotid gland. It has a tendency to recur with inadequate excision. Diagnosis is histopathologic. It is to be emphasized that adequate tissue samples should be taken in order to provide a definite diagnosis from biopsy, and subsequently institute proper definitive management.

@#<p style="text-align: justify;">Primary sinonasal ameloblastoma is an extremely rare odontogenic epithelial tumor histomorphologically identical to its gnathic counterparts but with distinct epidemiologic and clinicopathologic characteristics. We present a case of a 46-year-old female with a one year history of recurrent epistaxis, nasal obstruction and frontonasal headache. Clinical examination, CT scan and subsequent surgical excsion revealed an intranasal mass attached to the lateral nasal cavity with histomorphologic features of ameloblastoma and was signed out as extragnathic soft tissue ameloblastoma of the sinonasal area. Extraosseous extragnathic primary sinonasal ameloblastoma are rare but do occur and should be distinguished from infrasellar craniopharyngiomas.</p>
