Respirology Case Reports
|September 30, 2021
Summary
This report details the smallest bronchial carcinoid tumor found with peripheral squamous cell carcinoma. Early detection of bronchial carcinoids may be possible during bronchoscopy for lung tumors.
Area of Science:
- Pulmonology
- Oncology
- Pathology
Background:
- Combined bronchial carcinoid and lung cancer cases are rare.
- This study reports the smallest bronchial carcinoid associated with squamous cell carcinoma.
Observation:
- A 79-year-old male presented with an abnormal chest X-ray finding.
- Imaging revealed an ill-defined nodule in the left S9a area without lymph node involvement.
- Bronchoscopy identified a 1mm nodule at the left B8 orifice.
Findings:
- Surgical resection included left lower lobectomy.
- Pathology confirmed keratinizing squamous cell carcinoma (Stage IA3) in S9a and a typical bronchial carcinoid in B8.
- The patient remained recurrence-free two years post-surgery.
Implications:
- This case highlights the smallest bronchial carcinoid co-occurring with squamous cell carcinoma.
- Suggests careful bronchoscopic observation can aid early detection of bronchial carcinoids in patients with peripheral lesions.
- Contributes to understanding rare combined pulmonary neoplasms.

01:23The Bronchial Tree
4.2K
The human bronchi and bronchial tree play a crucial role in the respiratory system, facilitating the exchange of oxygen and carbon dioxide. Let's delve into the intricate structure and functions of these respiratory components.
The trachea, commonly known as the windpipe, is a tube that connects the larynx (voice box) to the bronchi. At a point called the carina, it bifurcates into two primary bronchi. The right primary bronchus is wider, shorter, and more vertical than the left primary...

Respiratory disorders encompass a range of conditions with varying levels of severity. Asthma, marked by chronic airway inflammation and hypersensitivity, is one such condition. It can lead to airway obstruction due to factors like bronchial spasms, mucosal edema, increased mucus secretion, or epithelial damage. Asthma triggers are diverse, ranging from allergens to emotional upset, and treatment focuses on both immediate relief through bronchodilators and long-term inflammation suppression.

Understanding the variety of primary symptoms and systemic complications that characterize chronic obstructive pulmonary disease (COPD) is crucial for healthcare professionals.
Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.

Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
