During 1905 and 1906, Heerfordt had the opportunity of observing three patients in the Copenhagen City Hospital, each of whom presented so similar and so striking a clinical picture that in 1909 he ventured to describe the condition as a hitherto unrecognized clinical entity. There were three essential and outstanding features in these cases: enlargement of the parotid glands lasting several months and thus running a relatively chronic course in contrast with the acute swelling in epidemic parotitis; an ocular inflammation involving the uveal tract, and a long continued fever of low degree corresponding with the subchronic course of both the iridocyclitis and the parotitis.

For this symptom-complex, Heerfordt proposed the descriptive title febris uveoparotidea subchronica, thus emphasizing the three chief characteristics and the course of the disorder.
Heerfordt's1 communication was followed by numerous case reports of a similar
