title: Bilaterally enlarged parotids and sicca symptoms as a presentation of sarcoidosis: Pivotal role of aspiration cytology in diagnosis.
abstract: Sarcoidosis is a chronic multisystem inflammatory disease of unknown etiology characterized by widespread noncaseating granulomas in various organs. The diagnosis of sarcoidosis is based on cytological, clinicolaboratory, and radiological findings, and requires careful exclusion of other granulomatous diseases especially tuberculosis. Involvement of parotid glands is uncommon. Presentation of sarcoidosis with sicca symptoms that include dryness of eyes and mouth is an even rarer phenomenon. We present a case of multisystemic sarcoidosis presenting with dryness of eyes and mouth along with bilateral enlargement of parotid glands. Fine-needle aspiration cytology (FNAC) smears showed epithelioid cell granulomas and multinucleate giant cells. Stain for acid-fast bacilli was negative. Careful cytological examination revealed crystalline structures inside the giant cells, which prompted us to evaluate the patient for sarcoidosis. This case report highlights the cytological features that can be useful in clinching the diagnosis of sarcoidosis in conjunction with clinicoradiological and laboratory findings in a clinically unusual case.
