Summary
Histoplasmosis, a fungal infection, can cause rare complications like vocal cord paralysis. This case highlights an unusual instance of right vocal cord paralysis due to mediastinal lymphadenopathy from histoplasmosis.
Area of Science:
- Infectious Diseases
- Otolaryngology
- Pulmonology
Background:
- Histoplasma capsulatum is a common dimorphic fungus in endemic areas.
- Mediastinal lymphadenopathy can arise from histoplasmosis.
- Vocal cord paralysis is a potential, though rare, complication.

Larynx
2.3K
The human larynx, often referred to as the voice box, is an intricate organ located in the neck. It serves as a pathway for air to enter the lungs during respiration and is an essential component of voice production.
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids,...

Respiratory System Abnormal Finding II: Palpation and Auscultation
799
In assessing respiratory abnormalities, palpation and auscultation are critical tools for detecting and interpreting various pathophysiological changes. These techniques provide insight into underlying disorders by evaluating tactile sensations and sounds produced by the respiratory system.
Palpation Findings
During a respiratory assessment, palpation can reveal several vital abnormalities:

Chronic Pharyngitis
5.7K
Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

Pleural Effusion Overview
A pleural effusion is the abnormal collection of fluid between the parietal and visceral pleura layers of tissue that form the lining of the lungs and chest cavity. It can occur independently or due to surrounding parenchymal diseases, such as infection, malignancy, or inflammatory conditions.
