Summary
Epithelioid hemangioendothelioma, a rare lung cancer, was successfully treated with azathioprine in a unique case presenting with hypertrophic pulmonary osteoarthropathy. This patient remains well 16 years post-diagnosis, showing no decline in lung function.
Area of Science:
- Pulmonology
- Oncology
- Pathology
Background:
- Epithelioid hemangioendothelioma (EHE) is an exceptionally rare vascular neoplasm primarily affecting the lungs, with fewer than 40 documented cases globally.
- This report details a unique case of pulmonary EHE that co-occurred with hypertrophic pulmonary osteoarthropathy.
Observation:
- The case involved a patient diagnosed with pulmonary EHE who presented with hypertrophic pulmonary osteoarthropathy.
- Radiographic and spiral CT imaging documented the progression of this rare pulmonary neoplasm.
Findings:
- The patient received treatment with azathioprine.
- Remarkably, the patient has remained alive and well for 16 years post-diagnosis without any deterioration in pulmonary function.
Implications:
- This case highlights a potential long-term treatment option for pulmonary EHE, even in advanced presentations.
- It underscores the importance of considering rare neoplasms in the differential diagnosis of complex pulmonary conditions.
- Further research into the cellular origin, cytological features, and prognostic factors of pulmonary EHE is warranted.
