Core-Needle Biopsy of Thyroid Mass with Uncertain Malignant Potential.. Online Journal of Health and Allied Sciences. 2024 Dec; 23(92): 1-30972-5997https://imsear.searo.who.int/handle/123456789/247874Thyroid cancer is an emerging problem worldwide. Patients undergo surgery based on the results of cytology classified according to the Bethesda System for Reporting Thyroid Cytopathology. However, patients with Bethesda III and IV often undergo surgery due to “suspicion” of malignancy. In reality up to 68% of cases do not require surgery as the mass is not malignant. Core-needle biopsy (CNB) is an emerging new diagnostic method that can be useful to diagnose thyroid malignancies. It is potentially useful in cases of Bethesda III and IV as the obtained tissue can undergo immunohistochemistry and genetic testing. We present a case of 58-year old female initially diagnosed with a thyroid mass suspicious for thyroid cancer who undergone CNB that demonstrated benign nature of the tumor and eventually undergone organ-sparing surgery.Thyroid surgeryFollicular tumorCore-needle biopsyThyroid cancer.Journal ArticleIndiaDepartment of Clinical Research and Development, Botkin Hospital, Moscow, Russia; Department of Surgery, Russian Medical Academy of Continuous Professional Education, Moscow, RussiaDepartment of Clinical Research and Development, Botkin Hospital, Moscow, RussiaDepartment of Clinical Research and Development, Botkin Hospital, Moscow, RussiaDepartment of Clinical Research and Development, Botkin Hospital, Moscow, RussiaDepartment of Clinical Research and Development, Botkin Hospital, Moscow, RussiaDepartment of Clinical Research and Development, Botkin Hospital, Moscow, RussiaDepartment of Medicine, Moscow State Medical University I.M.
