Prolonged generalized pruritus associated with selective elevation of IgA as the presenting symptoms of sarcoidosis

The purpose of this case report is to describe the possible initial presentation of sarcoidosis as generalized prolonged pruritus.

In a patient presenting with prolonged generalized pruritus who also had selective elevation of IgA, the diagnosis of sarcoidosis was confirmed by bilateral interstitial infiltrates on chest radiograph, elevated angiotensin-converting enzyme, and dermal granuloma on skin biopsy from a recent rash.

Sarcoidosis should be added to the list of diseases associated with prolonged pruritus and routine chest radiographs should be obtained in these patients.
