ABSTRACT

Papillary thyroid carcinoma is the most common malignant tumor of the thyroid, accounting for over 85% of thyroid cancers. Among its more than 15 subtypes, diffuse sclerosing subtype papillary thyroid carcinoma (DSPTC) is a rare form, comprising less than 6% of all thyroid cancers. It predominantly affects younger patients and is known for its aggressive behavior, often presenting with lymph node metastasis. DSPTC shows characteristic ultrasound features such as diffuse microcalcifications and heterogeneous hypoechoic areas, which are key in its diagnosis. However, it can sometimes resemble Hashimoto’s thyroiditis, requiring careful differential diagnosis. Early detection through ultrasound and appropriate treatment significantly improve patient outcomes.
