Differences in the form of presentation between papillary microcarcinomas and papillary carcinomas of larger size

Abstract

Papillary thyroid carcinomas (PTCs) with a diameter ≤1 cm are referred to as papillary microcarcinomas (PTMCs). The prognostic factors for PTMCs have not been defined. Different clinical and histopathologic variables were studied in 152 PTCs, including 74 PTMCs and 78 PTCs of larger size. We found that PTMCs are associated with less multifocality (P =.046) and bilaterality (P =.003), fewer lymphadenectomies (P
