Multifocal incidental papillary microcarcinoma of thyroid: Diagnostic pitfall in cytology

Papillary microcarcinoma (PMC) of a thyroid tumor measuring 10 mm or less in maximum diameter. PMC of thyroid is an incidental finding, and some of them show multifocality. Here, we present a case of 33-old adult male diagnosed on cytology as benign follicular nodule and subsequently diagnosed as multifocal incidental PMC in the colloid nodule of thyroid on histopathology. PMC of thyroid is a diagnostic pitfall on cytology and ultrasonography-guided aspiration should be done. Optimal therapeutic and management strategy needs to be determined for PMC of thyroid.
