A case of in vivo diagnosis of generalized idiopathic amyloidosis

Idiopathic amyloidosis, unlike secondary amyloidosis, develops in the absence of previous disease. Its clinical presentation is multifaceted, determined by the lesion of certain organs and highly variable during the course of the disease. All manifestations of the disease are nonspecific. In contrast to secondary amyloidosis, idiopathic amyloidosis more often involves cardiovascular, respiratory, digestive and urinary systems. In vivo diagnosis of idiopathic amyloidosis is difficult due to its imitation of many diseases; in practice, it is recognized less often than it occurs.
