Abstract
Introduction: In the last decade, there has been an increase in the incidence of differentiated thyroid cancer, especially microcarcinomas, whose behavior is usually indolent, with overdiagnosis and unnecessary aggressive therapies with significant economic implications. This study's objective was to describe a patient with a thyroid neoplasm with low malignant potential whose treatment is purely surgical.
Clinical case: A 36-year-old man underwent surgery for a thyroid nodule classified Bethesda VI, where the post-surgical histopathology showed a non-invasive follicular thyroid neoplasm with nuclear papillary characteristics (NIFTP). The evolution was favorable; he did not need the substitution of levothyroxine or radioactive iodine.
Discussion: Non-invasive follicular variants of PTC have a meager malignant potential, so the ATA classified it as a low-risk neoplasm whose treatment is purely surgical, changing its name to NIFTP.
Conclusion: NIFTP has an excellent prognosis, hemithyroidectomy being sufficient in most cases.
