Aggressive Papillary Thyroid Microcarcinoma

Abstract

Although most PMCs have an indolent course, there is a fraction (19% in our series) of patients with PMC and aggressive behavior strongly correlated with some histopathological features (extrathyroid invasion, solid pattern, tumor multifocality, and absence of a capsule) who need to be individualized and for whom a radical therapeutic approach is recommended based on total thyroidectomy and lymphadenectomy followed by radioiodine administration.
