This case report details a rare instance of pulmonary pyoderma gangrenosum presenting before skin symptoms and without systemic disease. Early diagnosis and corticosteroid treatment led to patient recovery.
Area of Science:
- Pulmonary Medicine
- Dermatology
- Pathology
Background:
- Pyoderma gangrenosum (PG) is a chronic sterile neutrophilic dermatosis.
- It often associates with systemic conditions like inflammatory bowel disease.
- Extracutaneous PG is rare, typically affecting the lungs.
Observation:
- A 19-year-old male presented with respiratory symptoms (shortness of breath, cough).
- Initial skin examination revealed no lesions.
- Chest CT showed consolidations, cavitation, nodules, and pleural effusions.
Findings:
- Bronchoalveolar lavage and autoimmune panel were unremarkable.
- Lung biopsies confirmed pulmonary pyoderma gangrenosum.
- This is the first reported case of pulmonary PG without cutaneous or systemic manifestations.
Implications:
- Highlights the possibility of primary pulmonary pyoderma gangrenosum.
- Emphasizes the need for vigilant follow-up for potential systemic or cutaneous disease development.
- Corticosteroid therapy proved effective in this unique presentation.
