Summary: This study assessed the diagnostic value of various immunohistochemical markers for differentiating among benign follicular nodules, noninvasive follicular thyroid neoplasms, noninvasive encapsulated follicular variants of papillary thyroid carcinoma, and infiltrative FVPTC. Results showed specific markers with high sensitivity and specificity in distinguishing different types of lesions, with various combinations enhancing diagnostic accuracy. The similar IHC profiles of NIFTP and NEFVPTC suggest a reliable NIFTP diagnosis and a possible spectrum of progressing neoplasia.

Summary: This study retrospectively reviewed the clinical and histological features of pediatric cases with follicular patterned thyroid nodules with nuclear features of papillary thyroid carcinoma (PTC), focusing on the invasive encapsulated follicular variant of PTC (Ienc-fvPTC) and infiltrative fvPTC (inf-fvPTC) subtypes. The study found that pediatric NIFTP and fvPTC subtypes demonstrate alignment between clinical and histological risk stratification, with indolent behavior in Ienc-fvPTC and invasive features in inf-fvPTC tumors.

Summary: This study investigated the molecular differences among follicular-patterned thyroid tumors through proteomic analysis. The results identified differentially regulated proteins that can differentiate between different types of thyroid tumors.

Summary: This cohort study examined the impact of different treatments on the prognosis of follicular variant papillary thyroid carcinoma (FVPTC) and classical papillary thyroid carcinoma (CPTC) patients. The findings suggest that combination therapy is associated with a decreased risk of 5-year mortality in CPTC and FVPTC patients.

Summary: Columnar cell variant (CCV) is primarily a BRAF-driven tumor, with most cases also harboring secondary oncogenic mutations and multiple chromosomal gains and losses. Molecular analysis could potentially help risk stratify CCV.

Summary: This study found a correlation between the extent of invasion and prognosis in patients with encapsulated angioinvasive follicular thyroid carcinoma. Patients with two or more foci of vascular invasion, especially those aged 55 years and above, should be closely monitored.

Summary: Papillary thyroid carcinoma (PTC) is the most common type of thyroid malignancy, with some tumors being totally or partially encapsulated known as encapsulated (conventional) variant. Clinicopathological features of encapsulated PTC were compared with non-encapsulated conventional type, showing no significant differences except for prominent cystic changes. Evaluation of capsular invasion status is recommended for predicting lymph node metastasis in encapsulated PTC.

Summary: This study evaluated the accumulation of lipid droplets and the expression of adipophilin in follicular thyroid carcinoma (FTC) cells. It was found that FTC cells had abundant lipid droplets and adipophilin expression, while follicular thyroid adenoma (FTA) had less. Therefore, assessing adipophilin expression can help differentiate FTC from FTA in surgical specimens.

Summary: This article describes a case of invasive lobular carcinoma with solid and encapsulated papillary carcinoma growth pattern, which may present a diagnostic challenge, but the diagnosis was ultimately confirmed through immunohistochemistry and next-generation sequencing. Immunohistochemical analysis is crucial for differential diagnosis. The understanding of this newly discovered variant expands the morphological spectrum of invasive lobular carcinoma and helps to prevent misdiagnosis.

Summary: The study aimed to explore the sonographic features of follicular thyroid carcinoma (FTC) and differentiate it from follicular thyroid adenoma (FTA). Results showed that an interrupted halo and satellite nodule(s) with or without halo ring are specific sonographic features for FTC. Sonography could play a role in distinguishing FTC from FTA.

Summary: Diffuse sclerosing variant (DSV) of papillary thyroid carcinoma, a rare and aggressive form of thyroid cancer, has a worse prognosis compared to classical papillary thyroid carcinoma (c-PTC). DSV is often driven by fusion events and carries a higher risk of recurrent disease and distant metastasis.

Summary: This study evaluated the differences between papillary thyroid carcinoma (PTC) with different proportions of hobnail features and hobnail variant (HVPTC), finding that tumors with more than 30% hobnail areas are more likely to have distant metastasis and structural persistence, indicating the need for special attention.

Summary: The study showed that the tall cell variant of papillary thyroid carcinoma has increased expression of cancer stem cell markers compared to classic papillary thyroid carcinoma. A gene signature similar to the tall cell variant identified a subtype of classic papillary thyroid carcinoma with worse recurrence-free survival.

Summary: This study investigated the prognostic factors and appropriate STI cutoff for papillary thyroid carcinoma, solid variant (PTC-SV) through a multi-institutional study. The results suggest that the determining factor for nodal metastasis and disease-free survival (DFS) in PTC-SV is the encapsulation/infiltration status rather than the percentage of solid/trabecular/insular growth (STI).
