Sinonasal and laryngeal sarcoidosis.

Sarcoidosis is a chronic granulomatous inflammation of uncertain etiology that can involve any organ system in the body. Sinonasal and laryngeal involvement is rare, poorly understood, and difficult to diagnose. Additionally, the extent of the disease is variable, and the response to systemic corticosteroids is often poor. We report a case of a 55-year-old woman with prior cutaneous sarcoidosis who presented with chronic nasal congestion, difficulty breathing, dysphonia, and stridor, and biopsy of the nasal vestibule revealed noncaseating granulomatous inflammation.
