There are multiple small hypoechoic/mixed cystic and solid nodules in the thyroid gland, Zhejiang Province Basic Public Welfare Research Program Project (grant number GF22H165705). From: Surgery of the Thyroid and Parathyroid Glands (Third Edition), 2021, In Diagnostic Pathology: Intraoperative Consultation (Second Edition), 2018, Parathyroid parenchyma can resemble thyroid parenchyma, Pseudofollicular and trabecular structures can be present, Pseudofollicles can contain eosinophilic material that simulates colloid, Oxyphilic cells can resemble Hrthle cell nodule of thyroid, Features helpful to identify true parathyroid parenchyma, Cells smaller and more vacuolated than thyroid cells, Nuclei have rounder and denser chromatin than thyroid nuclei, Lack birefringent and polarizable calcium oxalate crystals seen in thyroid, Pseudofollicles can contain material that closely mimics colloid, Thyroid parenchyma can resemble parathyroid parenchyma, Stromal edema or ice crystal artifact can simulate adipose tissue, Rarely, true adipose metaplasia can be present within thyroid tissue, Hrthle cells of thyroid can be mistaken for oxyphil cells, True thyroid follicles often contain calcium oxalate crystals that are easily seen with polarization, Calcium oxalate crystals are not seen in parathyroid tissue, Ice crystal artifact can mimic adipose tissue within lymph node and mimic parathyroid gland, Parathyroid tissue has more cytoplasm than lymphocytes, Assessing cellularity in small biopsies can be difficult, Variable within parathyroid glands and among glands in single individual, Polar regions of parathyroid more cellular than central, Cellularity increases with age and varies with gender, ethnicity, and body habitus, In Imaging Anatomy: Ultrasound (Second Edition), 2018, Normal thyroid parenchyma has fine, uniform echoes and is hyperechoic compared to adjacent muscles, Echogenic thyroid capsule is clearly visualized and helps to differentiate thyroid lesions from extrathyroidal masses, Both longitudinal and transverse scans are required for comprehensive ultrasound assessment of thyroid gland, Transverse scan helps to locate thyroid nodules, their relationship to trachea, major vessels in carotid sheath, and to evaluate internal architecture and extrathyroid extension, Longitudinal scan helps to evaluate internal architecture, vascularity on Doppler, and extrathyroidal extension, Assessment of adjacent structures (including trachea, esophagus, strap muscles, carotid artery, and internal jugular vein) and cervical lymph nodes, In Diagnostic Pathology: Head and Neck (Second Edition), 2016, Destruction and replacement of thyroid parenchyma by dense collagen (keloid-like bands of fibrosis), Fibrosing process is not confined to thyroid but also involves extrathyroidal connective tissue structures, such as, Muscle, adipose tissue, nerves, and vascular spaces, In addition to fibrosis, chronic inflammatory cell infiltrate is present, Predominantly composed of mature plasma cells and lymphocytes; eosinophils may be present, Vasculitis is present primarily involving veins (phlebitis) characterized by adventitial inflammation that may invade through full thickness of vessel wall with thrombotic effect, May be readily apparent or may be difficult to identify; not present in all cases, Remnant of thyroid follicles may be present (but may be difficult to identify), Not associated with oxyphilic metaplasia (as seen in chronic lymphocytic thyroiditis) or granulomatous inflammation, In some cases, preexisting or coexisting lesions may be present, e.g., adenomatoid nodule(s), follicular adenoma, follicular carcinoma, thyroid papillary carcinoma, Vania Nos MD, PhD, in Diagnostic Pathology: Endocrine (Second Edition), 2018, Reactive histologic features present in thyroid parenchyma, Absence of follicular cells within needle tract in addition to other reactive features indicates PFNAC, Cells with reactive atypia may become dislodged into vessels mimicking appearance of vascular invasion, Andreas Machens MD, PhD, Henning Dralle MD, PhD, in Advances in Treatment and Management in Surgical Endocrinology, 2020, Invasive growth emerges from within the thyroid parenchyma (extrathyroidal extension) or from within the lymphatic mesenchyma (extranodal growth).26 Two types of locoregional soft tissue infiltrates are to be distinguished: (1) by direct extension of, and/or venous microembolization from, a primary tumor penetrating the thyroid capsule, more commonly seen in the central neck; and (2) by growth of lymph node metastases through the nodal capsule, more often found in the lateral neck.27, Primary tumor size >20mm is independently associated with histology-proven lymph node recurrence. Connect with a U.S. board-certified doctor by text or video anytime, anywhere. Further inquiries can be directed to the corresponding author. Moreover, swollen and hard lymph nodes could be palpated on both sides of the neck, with a maximum size of approximately 2.0*1.0 cm. This is why tumor cells are thought to spread via lymphatic channels regardless of whether the primary thyroid tumor, breaching the thyroid capsule, extends into neighboring soft tissues or not.27 Because each thyroid primary can contribute lymph node metastases on its own, multifocal MTC is more frequently node-positive than unifocal MTC.28, Thyroid primaries in the upper thyroid pole may skip the central neck compartment, invading the superior lateral lymph nodes directly. Thyroid (2015) 25(3):31424. whats your opinion? In conclusion, the diagnosis of TM should be based on ultrasound, FNAC and the patients past medical history. Ann Surg Oncol (2017) 24(6):15339.
