Familial sarcoidosis terminating as neurosarcoidosis

Familial sarcoidosis: Report of a mother and her son

Sarcoidosis is a chronic, multisystemic inflammatory disease, characterized with noncaseating granulomas. The pathogenesis of the disease is not yet clear, however, the main hypothesis is impaired and inadequate immune response developing against different environmental triggers in genetically predisposed people. The role of genetic factors in the development of sarcoidosis is well known. Over many years, familial sarcoidosis cases have been reported in various studies. In this report, we present familial sarcoidosis cases in a mother and her son.

Peripheral nerve involvement in sarcoidosis: an electrodiagnostic study

The frequency of peripheral nerve involvement in sarcoidosis is uncertain. To determine how often peripheral nerves are affected in the absence of symptoms, electromyography was performed on 29 sarcoid patients and 29 age-matched controls. Nineteen sarcoid patients, compared to two controls, had abnormally low sensory amplitudes in one or more nerves, and the mean sensory amplitudes for median, ulnar, and sural nerves were lower in the patient than in the controls. Subclinical mononeuropathy multiplex appears to be common in sarcoidosis.
