ABSTRACT
The clinical course of sarcoidosis is often prolonged and may
be preceded by a varying period in which granulomatous
changes are present in various organs without causing
symptoms. It is also certain that some individuals go through
the entire course of sarcoidosis to spontaneous resolution
without symptoms, or with only trivial ones, although
granulomas, if sought, would be found in involved organs.
Thus it is to be expected that a proportion of patients will
show evidence of some other disease during the course of
known sarcoidosis; and that also during the investigation of
patients found to be suffering from some other disease,
evidence of previously unsuspected sarcoidosis will be found
occasionally.
