Abstract
Diffuse sclerosing variant is an uncommon subtype of papillary thyroid carcinoma (PTC). The clinical presentation often resembles Hashimoto's thyroiditis. Histopathological features are similar to conventional PTC; however, diffuse involvement of both lobes, extensive cervical lymphadenopathy, numerous psammoma bodies, extensive lymphocytic infiltrates, and fibrosis suggest a high possibility of this rare variant.
