Summary
This case report details the first instance of endobronchial pheochromocytoma, a rare pulmonary manifestation. Management involved laser photoresection and stenting for symptom relief in a recurrent extra-adrenal tumor.
Area of Science:
- Pulmonology
- Oncology
- Endocrinology
Background:
- Pulmonary manifestations of pheochromocytoma are rare and poorly documented.
- Endobronchial involvement by pheochromocytoma has not been previously reported in medical literature.
Observation:
- A 37-year-old woman with recurrent extra-adrenal pheochromocytoma presented with persistent wheezing and cough, initially misdiagnosed as asthma.
- Flexible bronchoscopy revealed endobronchial metastases, confirmed by biopsy.
Findings:
- This is the first reported case of endobronchial pheochromocytoma.
- The patient underwent Nd-YAG laser photoresection (LPR) and Wallstent placement for tumor ablation and airway management.
- Palliative LPRs were required multiple times, with the patient remaining well for 18 months post-treatment.
Implications:
- Highlights the importance of considering rare diagnoses in persistent respiratory symptoms.
- Demonstrates the feasibility of endobronchial tumor management using LPR and stenting.
- Contributes to understanding the diverse clinical presentations and management strategies for pheochromocytoma.
