Heerfordt syndrome
Heerfordt syndrome  is a rare manifestation of sarcoidosis. The symptoms include inflammation of the eye (uveitis), swelling of the parotid gland, chronic fever, and in some cases, palsy of the facial nerves.

Causes
The exact cause of Heerfordt syndrome has not yet been definitively determined. Of those patients who have been diagnosed with Heerfordt syndrome, 15% have a close relative who also has the syndrome. One possible explanation is that the syndrome results from a combination of an environmental agent and a hereditary predisposition. Mycobacterium and Propionibacteria species have both been suggested as the environmental agent, though the evidence for this is inconclusive.

Diagnosis
In patients that have already been diagnosed with sarcoidosis, Heerfordt syndrome can be inferred from the major symptoms of the syndrome, which include parotitis, fever, facial nerve palsy and anterior uveitis. In cases of parotitis, ultrasound-guided biopsy is used to exclude the possibility of lymphoma. There are many possible causes of facial nerve palsy, including Lyme disease, HIV, Melkersson–Rosenthal syndrome, schwannoma, and Bells palsy. Heerfordt syndrome exhibits spontaneous remission.

Treatment
Treatments for sarcoidosis include corticosteroids and immunosuppressive drugs.

Prevalence
In the United States, sarcoidosis has a prevalence of approximately 10 cases per 100,000 whites and 36 cases per 100,000 blacks. Heerfordt syndrome is present in 4.1 to 5.6% of those with sarcoidosis.

History
The condition was first described in 1909 by Danish ophthalmologist Christian Frederick Heerfordt, for whom the syndrome is now named. It was originally attributed to mumps, but after further studies by Swedish doctor Jan G. Waldenström in 1937, it was classified as a distinct manifestation of sarcoidosis.
