It is often pointed out that the incidence of sarcoidosis in Japan is on the increase, while the etiology of the disease still remains unknown.
This disease mainly involves the lungs, eyes, lymphnodes, skin, nervous system and bones, but it also involves various tissues and strucures in the field of otolaryngology, which include the external nose, nasal mucosa, paranasal sinuses, nasopharynx, pharynx and larynx, trachea and bronchi, tonsils and adenoid, salivary gland, external and middle ear, acoustic and facial nerves. Otolaryngologists, accordingly, should be aware of this systemic disease for an early diagnosis.
The authors report on the otolaryngological manifestations of sarcoidosis in 15 cases that have been treated at St. Luke's International Hospital during the past 10 years and discuss contribution of otolaryngologists in the diagnosis of this disease.
