An exponential increase in the detection of papillary thyroid microcarcinomas (PTMCs) has been observed in recent times, possibly because of recent improvements in the management of thyroid lesions and extensive histological examination. However, no definitive treatment guideline has been developed for PTMC, resulting in patients undergoing overtreatment. In 2003, the term papillary microtumor of the thyroid (PMiT) was proposed for small (≤1 cm) intrathyroidal tumors with excellent prognostic prospects along with strict definition criteria. Since then, the term PMiT has been adopted by clinicians and surgeons. In this article, the authors report a series of 50 consecutive cases of PMiT collected and treated at the University Hospital of Turin, Italy. From the authors’ experience, this terminology, which demarks a subset of PTMC, should be widely adopted as it is biologically sound, well accepted by both clinicians and patients, decreases the danger of overtreatment, minimizes the psychological anxiety engendered by a diagnosis of carcinoma, and maintains the patient’s eligibility for health insurance.

Abstract
An exponential increase in the detection of papillary thyroid microcarcinomas (PTMCs) has been observed in recent times, possibly because of recent improvements in the management of thyroid lesions and extensive histological examination. However, no definitive treatment guideline has been developed for PTMC, resulting in patients undergoing overtreatment. In 2003, the term papillary microtumor of the thyroid (PMiT) was proposed for small (≤1 cm) intrathyroidal tumors with excellent prognostic prospects along with strict definition criteria. Since then, the term PMiT has been adopted by clinicians and surgeons. In this article, the authors report a series of 50 consecutive cases of PMiT collected and treated at the University Hospital of Turin, Italy. From the authors’ experience, this terminology, which demarks a subset of PTMC, should be widely adopted as it is biologically sound, well accepted by both clinicians and patients, decreases the danger of overtreatment, minimizes the psychological anxiety engendered by a diagnosis of carcinoma, and maintains the patient’s eligibility for health insurance.
