An atypical form of a disease in which the usual symptoms fail to appear and its progress is stopped at an earlier stage than would ordinarily be expected.
An aborted or incomplete form of disease arrested before running its course; an atypical and indefinite manifestation of an illness.
The phrase used to denote any disease that doesn’t adhere to its typical progression is “forme fruste”. This condition can manifest in different ways. It could be where some of the disease’s signature symptoms don’t show up or when the advancement of the illness halts sooner than anticipated.
