Respirology Case Reports
|August 25, 2020
Summary
A young man with shortness of breath had a lung collapse due to an endobronchial tumor. Diagnosis was metastatic embryonal carcinoma, treated with surgery and chemotherapy.
Area of Science:
- Oncology
- Pulmonology
- Urology
Background:
- Embryonal carcinoma is a rare germ cell tumor.
- Metastatic spread to the lungs can cause significant respiratory compromise.
- Endobronchial obstruction is an uncommon presentation of metastatic disease.
Observation:
- A 24-year-old man presented with dyspnea and hemoptysis.
- Chest X-ray showed complete left lung collapse.
- Bronchoscopy identified an endobronchial tumor obstructing the left main bronchus.
Findings:
- Cryosurgical excision of the tumor was performed.
- Pathology confirmed metastatic embryonal carcinoma.
- The patient had a history of testicular germ cell tumor, necessitating right orchiectomy.
Implications:
- This case highlights the importance of considering metastatic embryonal carcinoma in young adults with unexplained respiratory symptoms.
- Multidisciplinary management involving pulmonology, oncology, and urology is crucial.
- Successful treatment involved a combination of surgical debulking and platinum-based chemotherapy (bleomycin, etoposide, cisplatin).

6.2K
Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

01:30Endoscopic Studies I: Bronchoscopy and Thoracoscopy
387
Endoscopy is a non-surgical medical technique used to examine a person's internal organs and vessels. This lesson will focus on two types of endoscopic studies: bronchoscopy and thoracoscopy.
Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...

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...
