Blue rubber bleb nevus syndrome: endobronchial involvement presenting as chronic cough

This case report describes a rare presentation of chronic cough secondary to endobronchial involvement with blue rubber bleb nevus syndrome (BRBNS) lesions. BRNBS is a rare syndrome characterized with cavernous hemangiomas involving the skin and GI tract. We report the case of a 37-year-old woman, with known BRBNS, who acquired an intractable cough with a radiograph revealing multiple pulmonary nodules. A bronchoscopy demonstrated various bluish, raised, and hypervascular lesions characteristic for BRBNS involving the right mainstem bronchus and segmental bronchi. To our knowledge, this is the first report of endobronchial involvement with BRBNS.
