まとめ
一般的な肺外結核の形態である結核性リンパ節炎(TBL)は、非定型的に現れることがあります。FNACは、Gene XpertおよびAFB検査が陰性であっても、早期診断に役立ちます。
科学分野:
- 医学;感染症;腫瘍学
背景:
- 結核性リンパ節炎(TBL)は、最も頻度の高い肺外結核(EPTB)の症状であり、症例の20%〜40%を占めます。;頭頸部におけるTBLの非定型的な現れ方は、他の重篤な疾患を模倣する可能性があり、診断上の課題をもたらします。
研究 の 目的:
- 頭頸部における非定型的な結核性リンパ節炎(TBL)の症例を報告すること。;従来の検査が陰性である場合のTBLにおける穿刺吸引細胞診(FNAC)の診断的有用性を強調すること。
主な方法:
- 進行性の顎の腫れを呈した45歳男性の症例提示。;診断ワークアップには、初期の悪性腫瘍の誤診、それに続く組織病理学的検査(HPE)、FNAC、抗酸菌(AFB)染色、およびGene Xpert検査が含まれました。;治療には2ヶ月間の抗結核薬レジメンが含まれました。
主要な成果:
- 初診時は癌が疑われましたが、HPEにより結核性肉芽腫性病変が明らかになりました。;FNACはTBLを示唆しましたが、AFB染色およびGene Xpertは結核菌に対して陰性でした。;患者は2ヶ月間の抗結核薬レジメンで著しい改善を示しました。
結論:
- 頭頸部における非定型的なTBLの現れ方には、高い疑いが必要です。;FNACは、AFB染色およびGene Xpertの結果が陰性であっても、TBLの診断に有用で迅速かつ低侵襲なツールです。;TBLの早期診断と治療は、患者の良好な転帰のために不可欠です。

Pulmonary Tuberculosis I
Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Pulmonary Tuberculosis II
Tuberculosis, or TB, is a bacterial infectious disease caused by Mycobacterium tuberculosis. While its primary impact is on the lungs, leading to pulmonary tuberculosis, it can also affect various other organs, a condition referred to as extrapulmonary tuberculosis.
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...

Pulmonary Tuberculosis III
Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:

Pulmonary Tuberculosis IV
Tuberculosis, more commonly referred to as TB, is an infectious disease stemming from Mycobacterium tuberculosis. While it primarily impacts the lungs, TB can also affect other body areas. Given its severity and global impact, timely and accurate diagnosis is crucial for controlling its spread and improving patient outcomes.
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...

Pulmonary Tuberculosis V
Medical management of tuberculosis (TB) patients involves a comprehensive approach that includes diagnosis, treatment, and monitoring. The specific strategies can vary depending on the type of tuberculosis (latent or active), the patient's overall health status, and other considerations.
Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the progression...

Tuberculosis
Tuberculosis (TB) remains a significant global health concern, primarily targeting the lungs and spreading through airborne transmission. Infection begins when aerosolized droplet nuclei, expelled by an individual with active TB, are inhaled by another person. These microscopic particles carry Mycobacterium tuberculosis, the causative agent of TB. Upon reaching the alveoli, the bacilli are engulfed by alveolar macrophages. However, due to their specialized lipid-rich cell wall, these pathogens...
