Ear and nose involvement in systemic diseases.

: A whole range of otolaryngeal manifestations may occur as complications or represent the first symptom and sign of a variety of systemic diseases. Otolaryngologists are often the first physicians to recognize that otolaryngeal abnormalities are symptomatic of a broader disease and mandate a systemic approach to the problem. In the present study, the authors focus primarily on ear, nose and throat manifestations that may occur in the context of systemic diseases, discussing clinical manifestations and reviewing the salient histologic, laboratory, and serologic features.
