Cytodiagnosis of Warthin’s Tumour in Submandibular Salivary Gland- A Rare Case Report

Abstract

The cytodiagnosis of Warthin’s tumour by Fine Needle Aspiration Cytology (FNAC) in the submandibular salivary gland in literature is sparsely reported. Constituting an outnumbered portion of salivary gland neoplasms, it is a monomorphic adenoma that mainly arises in parotid gland. The occurrence of it in minor salivary gland and submandibular salivary gland is minuscule. Therefore, the confrontation of cytomorphological features of Warthin’s tumour poises the problem of interpretation. In spite of the fact that, Warthin’s tumour dispense as a clinically benign, slow growing and asymptomatic lesion with minimal rate of recurrence, nevertheless this entity is contemplated peculiar because of its unknown origin and cytomorphological appearance. The cytopathological smears prepared depict papillaroid sheets of oncocytoid cells which entails careful distinction for its diagnosis. The present article outlined such rare case of Warthin’s tumour for its cytomorphological character and its clinical finding for its medical rarity. Here by, authors describe a case of Warthin’s tumour of two years duration in a 44-year-old male patient in the right submandibular gland. The clinical examination had revealed it to be a mass of 4x4 cm lying just below the angle of mandible, with solid as well as cystic components. As a part of presurgical diagnosis the patient was referred for FNAC. The smears were prepared from both components of swelling and the peculiar case was pondered over for various concepts regarding its clinicopathological features with main emphasis on cytomorphology.
