Adenoid cystic carcinoma: An unusual presentation

M Pushpanjali et al. J Oral Maxillofac Pathol. 2014 May.

Abstract

The adenoid cystic carcinoma is a relatively rare epithelial tumor of the major and minor salivary glands, accounting for about 1% of all malignant tumor of the oral and maxillofacial regions. Peak incidence occurs between the 5(th) and 6(th) decades of life. The clinical and pathological findings typical of this tumor include slow growth, peri-neural invasion, multiple local recurrences and distant metastasis. Herein, we report a case of adenoid cystic carcinoma of oropharynx with unusual clinical presentation. The diagnosis of this case and importance of cytology in diagnosing such cases is discussed.

Keywords: Adenoid cystic carcinoma; cribriform pattern; salivary gland malignancy.
