Anatomy of the Ear01:16

Anatomy of the Ear

8.7K
Auditory sensation, commonly called hearing, involves the transformation of sonic waves into neural impulses facilitated by the structures of the auditory organ. The prominent, flesh-like structure on the side of the head, called the auricle, directs sound waves towards the auditory canal. The auricle is often mislabeled as the pinna, a term more aligned with mobile structures like a feline's external ear. The auditory canal penetrates the cranium via the external auditory meatus of the...

Pulmonary Tuberculosis II01:28

Pulmonary Tuberculosis II

299
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...

Chronic Pharyngitis01:23

Chronic Pharyngitis

3.9K
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,...

Auditory Pathway01:15

Auditory Pathway

5.6K
Auditory pathways constitute the complex neural circuits responsible for transmitting and interpreting auditory information from the peripheral auditory system to the brain. Sound waves are initially captured by the outer ear, funneled through the ear canal, and reach the tympanic membrane (eardrum). These vibrations are transmitted via the middle ear's ossicles to the inner ear's cochlea.
When viewed cross-sectionally, the cochlea reveals the scala vestibuli and scala tympani flanking...

Skin Diseases and Disorders01:23

Skin Diseases and Disorders

4.0K
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Area of Science:

  • Otolaryngology
  • Dermatology
  • Pathology

Background:

  • Pyogenic granuloma (PG) is a common benign vascular tumor, typically affecting the skin and mucous membranes.
  • While often solitary, multiple PGs are rare, and their occurrence in the external auditory canal (EAC) is exceptionally uncommon.
  • The head and neck region accounts for one-third of PG cases, yet the EAC remains a rare site.

Purpose of the Study:

  • To report a rare case of multiple pyogenic granulomas in the external auditory canal.
  • To review existing literature on pyogenic granulomas in the external auditory canal.
  • To discuss clinical suspicion, diagnosis, and management of this rare presentation.

Main Methods:

  • Case report of a 36-year-old male with multiple PGs in the EAC.
  • Comprehensive literature review on pyogenic granulomas, focusing on external auditory canal involvement.
  • Discussion of clinical presentation, potential etiologies, and treatment strategies.

Main Results:

  • A unique case of multiple pyogenic granulomas was identified in the external auditory canal of a 36-year-old man.
  • The literature review confirmed the rarity of multiple PGs within the EAC.
  • Clinical suspicion for EAC PGs should consider trauma, hormonal changes, drug administration, rapid growth, and bleeding.

Conclusions:

  • Multiple pyogenic granulomas in the external auditory canal represent a rare clinical variation.
  • Surgical excision down to the perichondrium is recommended for symptomatic PGs to prevent recurrence.
  • Early diagnosis and appropriate management are crucial for favorable outcomes in these rare cases.
