Abstract:
We report a case of pseudotumoral, nodular, parenchymatous, primary pulmonary amyloidosis in a male patient under 50 years of age. The amyloidosis spread step by step, very progressively, over 12 years before Marie's disease developed. The pre-operative diagnosis was made by electron microscopy of an intrabronchial growth biopsy. Right pleuro-pneumonectomy was performed, resulting in regression of Marie's disease within 3 months. There was partial factor X deficiency. Four years after surgery, nodules have appeared in the left upper lobe, suggesting a recurrence.
Insights
This case study details a rare form of primary pulmonary amyloidosis in a man under 50. Surgical intervention led to regression of associated Marie's disease, though recurrence is possible.
Area of Science:
- Pulmonary Medicine
- Pathology
- Oncology
Background:
- Primary pulmonary amyloidosis is a rare condition characterized by abnormal protein deposition in the lungs.
- This report focuses on a specific pseudotumoral, nodular, parenchymatous presentation.
Observation:
- A male patient under 50 developed progressive pulmonary amyloidosis over 12 years.
- Intrabronchial growth biopsy with electron microscopy aided pre-operative diagnosis.
- Associated Marie's disease and partial factor X deficiency were noted.
Findings:
- Right pleuro-pneumonectomy resulted in rapid regression of Marie's disease.
- Recurrence of nodules in the left upper lobe appeared four years post-surgery.
Implications:
- Early diagnosis and surgical management can be effective for this rare pulmonary condition.
- Long-term monitoring is crucial due to the potential for recurrence.
- This case highlights the complex interplay between pulmonary amyloidosis, endocrine disorders, and coagulation factors.
