Case ReportsTracheobronchial pulmonary disease associated with pyoderma gangrenosum.
We report a tracheobronchial pulmonary manifestation caused by pyoderma gangrenosum, a neutrophilic dermatosis of unknown etiology. A 54-year-old man presented with pulmonary infiltrates followed by multiple painful cutaneous pustules on the scrotum. ⋯ Endobronchial biopsy demonstrated inflamed granulation and necrosis with infiltration by numerous neutrophils without vasculitis or granulomas, interpreted as pyoderma gangrenosum of the bronchi. Although the etiology of pyoderma gangrenosum is poorly understood, this case suggests that a common pathogenesis may account for the simultaneous cutaneous and airway inflammation.
