title: Sinonasal and nasopharyngeal adenoidcystic carcinoma: report of four cases.
abstract: Four cases of sinonasal and nasopharyngeal adenoidcystic carcinoma that came to the RIMS Hospital, Imphal during the period of July, 2002 to March, 2003 are reported in this article. The age incidence ranged from 30 to 80 years and the mean age was 47.5 years; with male to female ratio of 1:1. The average duration from first sympton in the patient to the date of his medical consultation was 17.8 months. Nasal obstruction was the first symptom two cases; lump sensation in the throat and headache in the third and fourth cases respectively. Despite the evidence of rapid and extensive local spread there were definitely delays from the patients' end to consult a clinician. Whereas the tumour itself is not common, the usual sites, if it occurs, are palate and minor salivary glands and rarely mucous and seromucinous glands elsewhere.
