Causes

The exact cause of Heerfordt's syndrome has not yet been definitively determined. Of those patients who have been diagnosed with Heerfordt's 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 and treatment

In patients that have already been diagnosed with sarcoidosis, Heerfordt's syndrome can be inferred from the major symptoms of the syndrome, which include parotitis
