title: [Morphology, morohogenesis, localization and diagnostic value of paramyxovirus-like particles].
abstract: Considering the most relevant features registered in the literature about the paramyxovirus-like structures, and based on personal investigations, it is allowed to accept that they are membranous structural differentiations of the endoplasmatic reticulum. They represent products of cellular degeneration towards the most heterogeneous stimuli. Their viral origin can be eliminated due to their presence in a variety of diseases non correlated physiopathologically. Their fast constant presence in the cases of lupus erythematosus and dermatomyositis allows to consider the paramyxovirus-like structures as an ultraestructural sign of diagnostic value in these diseases.
