まとめ
この研究では,CREB3L2::PPARγ融合に関連したパピラリ型核特征 (NIFTP) を有する非侵襲性小胞性甲状腺新生体の希少な症例が詳細に示されています. この発見は,甲状腺結節の診断とリスクの階層化における分子検査の重要性を強調しています.
科学分野:
- 内分泌学
- 外科病理学
- 分子診断
背景:
- 甲状腺の結節は一般的であり,正確な診断は患者の管理に不可欠です.
- 発症した悪性腫瘍と良性腫瘍を区別することは,特に卵泡状の病変は,診断上の課題です.
- 分子マーカーは 甲状腺がんリスクの階層化を精密にするためにますます利用されています.
研究 の 目的:
- CREB3L2::PPARγ融合を宿すパピラルのような核特征 (NIFTP) を有する非侵襲的な卵泡性甲状腺新生体の希少な症例を報告する.
- 臨床的,放射線学的,細胞学的,組織学的,そして分子学的発見を このユニークなケースに相関させる.
- NIFTPの診断と予後におけるこの希少な融合の影響を議論する.
主な方法:
- 甲状腺の結節を患った 58歳の女性の事例です
- 初期評価のため,超音波検査と細針吸血 (FNA) バイオプシーを行う.
- 細胞病理学的分析と ThyroSeq 分子検査
- 外科的切除 (左甲状腺の切除) と詳細な組織病理学的検査.
- BRAF V600Eとユビキチンに対する免疫ヒストキミカル染色
主要な成果:
- 細胞検査ではパピラー甲状腺がんが疑われ,分子検査ではCREB3L2::PPARγ融合が示された.
- ヒストポトロジーは 完全に封じ込められた 微小小胞状のノドルを確認しました NIFTPと一致し 侵入がないのです
- BRAF V600E変異は陰性であり,内核の偽含有はユビキチン陰性であった.
- NIFTPは稀なCREB3L2::PPARγ融合を隠し,悪性腫瘍の高リスクを示唆しています.
結論:
- このケースは,CREB3L2::PPARγ融合に関連したNIFTPの希少な例です.
- NIFTPにおけるこの融合の存在は,甲状腺腫瘍の分類の複雑さを強調する.
- 甲状腺結節の正確な診断とリスク評価には,包括的な臨床病理学的および分子評価が不可欠です.

The Thyroid Gland
4.3K
The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...

Synthesis and Regulation of Thyroid Hormones
5.1K
Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...

The Nucleolus
9.1K
The nucleolus is the most prominent substructure of the nucleus. When it was first discovered, it was considered to be an isolated organelle that forms fibrils and granules. In 1931, the relationship between the nucleolus and chromosomes was first described by Heitz. He observed that the appearance and size of nucleolus varies depending on the stage of the cell cycle. He also noticed constricted regions on different chromosomes clustered together at definite cell cycle stages. These regions,...

Papillary Dermis

Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen...
