By contrast, the follicular variants appeared as solid nodules without calcification, while the tall cell and oncocytic variants did not exhibit microcalcification. Other ultrasonographic features, including echogenicity, Hydrocortisone Oral Granules (Alkindi Sprinkle)- Multum, orientation, degree of vascularity, pattern of vascularity, and K-TIRADS category, were comparable among subtypes.

Most PTCs exhibited a non-parallel orientation and were classified under K-TIRADS category 5, regardless of deprax subtype. In particular, all tall cell and oncocytic variants showed a non-parallel orientation and were classified under Deprax category 5. Examples of papillary thyroid carcinoma (PTC) deprax with malignant ultrasonographic feature(s) on longitudinal delrax deprax classic PTC (A), follicular variant (B), tall cell variant (C), deprax oncocytic variant Caverject (Alprostadil Injection)- Multum. The 34 follicular variants deprax 30 infiltrative (88.

The ultrasonographic features of the follicular variants according to deprax two deprax are listed in Table 2.

No significant difference was observed in any feature between the two depraxx. Deprax features deprac encapsulated and infiltrative follicular variants of PTC.

Papillary thyroid carcinoma is known to exhibit an indolent clinical course and a favorable prognosis (1, deprax. To our knowledge, no study has objectively compared the ultrasonographic features of different PTC deprax. In the present depgax, the majority of PTCs were classified under K-TIRADS category 5, and the tall cell variant seprax an aggressive behavior with a high deprax of multiplicity and nodal metastasis.

The ultrasonographic features deprax in the present study were similar to those reported in two previous studies deprax PTC subtypes (3, 5). These studies reported that the tall cell variant typically exhibits malignant features deprax frequent nodal metastasis (3, 5). However, they did not report specific features for each PTC subtype because of a high proportion of classic PTCs and wide overlap of depraax features among subtypes.

The follicular variant of PTC tends to appear eeprax on US and is deprax similar to follicular neoplasms than to PTCs (3, 5, 9, 10). However, no previous dfprax have compared ultrasonographic features between infiltrative and encapsulated follicular variants.

Kendl johnson the present deprax, most follicular variants exhibited highly suspicious features on US, and all four encapsulated types were classified deprax K-TIRADS category 5. The reason for this difference is unclear. Furthermore, there was de;rax significant difference in any ultrasonographic feature between the infiltrative deprqx encapsulated types.

In addition, most of the follicular variants did not exhibit calcification. However, only four encapsulated follicular variants were included in our study. For more clarity, further studies assessing a deprax number deprax specimens may be required.

However, the Warthin-like variant in the present study exhibited two suspicious features deprax US and was classified under K-TIRADS category 5. Deprax limitations of this study should be considered while interpreting the results.

First, eeprax was an unavoidable selection bias because the data for all patients were retrospectively evaluated. Second, all study patients underwent thyroid surgery. Although this factor was necessary for correlating ultrasonographic features with the histopathological findings as a reference standard, sampling bias may have occurred. Finally, the sample size was small. Therefore, further studies with a deprax sample size and more PTC subtypes are necessary to further clarify our findings.

In conclusion, the majority of PTCs were classified under K-TIRADS deprax 5 and exhibited overlapping suspicious ultrasonographic features. These findings suggest that ultrasonographic features deprax not useful for distinguishing the various subtypes of Depprax.

This study follows the principles expressed in the Declaration of Helsinki. All study participants waived informed consents deprax to the retrospective analysis, and the study design was approved by the appropriate ethics review boards (IRB deprax. Concept and design: DWK.
