まとめ
甲状腺舌管嚢胞(TGDC)内の甲状腺乳頭癌(PTC)は稀です。Sistrunk手術を含む早期認識と個別化された治療は、長期的な経過観察で良好な転帰をもたらします。
科学分野:
- 内分泌学
- 腫瘍学
- 頭頸部外科
背景:
- 甲状腺乳頭癌(PTC)は最も一般的な分化型甲状腺癌です。
- 甲状腺舌管嚢胞(TGDC)は一般的な先天性頸部異常です。
- TGDC内に発生するPTCは例外的に稀で、症例の1.5%未満で発生します。
研究 の 目的:
- TGDCにおけるPTCのペルーの3例を提示すること。
- この稀な病態の診断および管理戦略を議論すること。
- 早期認識と個別化された治療の重要性を強調すること。
主な方法:
- TGDCにおけるPTCの3例の症例シリーズ提示。
- 診断ワークアップには、頸部超音波検査、造影CT検査、および穿刺吸引細胞診が含まれました。
- 手術管理は、Sistrunk手術、甲状腺全摘術、および放射性ヨウ素療法を含めて様々でした。
主要な成果:
- 3人の患者(34〜47歳)はいずれも頸部正中腫瘤を呈しました。
- 組織病理検査でPTC(古典的および濾胞型バリアント)が確認されました。
- 全患者は、6〜12年の追跡期間中、病気のない状態を維持しました。
結論:
- TGDCにおけるPTCは、一般的に良好な予後を持つ稀な病態です。
- 術前の画像検査および細胞診は、悪性腫瘍の疑いを高める可能性があります。
- 最適な管理には、腫瘍学的リスクおよび集学的意思決定に基づいた個別化された治療が必要です。

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.

The Thyroid Gland
7.7K
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...

Resistors In Series
6.6K
A resistor is an ohmic device that limits the flow of charge in a circuit. Most circuits have more than one resistor. If several resistors are connected together and connected to a battery, the current supplied by the battery depends on the equivalent resistance of the circuit. The equivalent resistance of a combination of resistors depends on both their individual values and how they are connected. The simplest combination of resistors is the series combination.

Series Resonance
837
The RLC circuit impedance is defined as the ratio of the supply voltage to the circuit current. Resonance in such a circuit occurs when the imaginary part of this impedance equals zero. This specific condition means that the inductive reactance is exactly equal to the capacitive reactance. The frequency at which this happens is known as the resonant frequency. Mathematically, the resonant frequency is inversely proportional to the square root of the product of the inductance (L) and capacitance...

Functions of Thyroid Hormones
5.6K
The thyroid hormone (TH) plays a pivotal role in the intricate orchestration of physiological processes, exerting profound effects on development, metabolism, and homeostasis throughout different life stages.
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...

Alveoli and Alveolar Ducts
5.9K
The respiratory zone of the human body, which stands in contrast to the conducting zone, comprises the structures that actively participate in the exchange of gases. The initiation of this zone is marked by the terminal bronchioles converging into respiratory bronchioles, the tiniest bronchiole classification. The respiratory bronchioles give way to the alveolar ducts that opens into a congregation of alveoli. Actively involved in gas exchange, alveoli resemble tiny sacs similar to clusters of...
