Introduction: Sarcoidosis is a granulomatous disease of unknown etiology, which in the majority of cases affects the lower respiratory tract. Although neck mass, parotid swelling and facial nerve palsy are considered the primary complaints in cases of head and neck sarcoidosis, sinonasal localization of the disease is also uncommonly reported.
Case: A 46 year old woman presented in our clinic with complaints of nasal congestion over a six month period. The patient reported increasing symptom severity in the last month with occasional purulent discharge. No other symptoms were reported. The patient's medical record was significant only for sarcoidosis localized to the lower respiratory tract. On anterior rhinoscopy, the nasal mucosa presented marked hypertrophy, purplish discoloration and granulomatous appearance of the inferior turbinates on the left side. The diagnosis of sinonasal sarcoidosis was made based on histopathologic examination of biopsy specimens.
Conclusion: Sinonasal sarcoidosis presents a challenging issue for the clinicial as its mimicking features may be misleading and delay diagnosis. In the present paper we present a case of sinonasal sarcoidosis presenting as chronic rhinosinusitis.
