Comparison of Histopathological Features of ‘Incidental’ and ‘Non-Incidental’ Papillary Thyroid Microcarcinomas

Abstract

The present study compares the histopathological parameters recently described for thyroid Pm, between the 'incidental' and 'non-incidental' groups, and determines their role, if any, in the manifestation of the disease. Materials and MethodsThe present study is a 5-year retrospective comparative study between 'incidental' and 'non-incidental' Pm. The data has been collected from January 2013 to December 2017. Patients diagnosed with Papillary thyroid microcarcinoma (Pm) and on follow-up with ultrasound of the neck and Iodine radioisotope uptake scan for detection of residual thyroid carcinoma were included in the present study. In case of tumor multifocality, size of the largest foci was considered in deciding to include it in Pm subgroup.
