In the blood film, hematoloyia lysates, resulting from viral infection, present similar aspects to those described by Gumprecht to refer to lymphocyte lysates at CLL After mcdonsld thorough and careful search, only a doctoral dissertation was found, in the area of Veterinary Medicine, where this term was used It is known that viral conditions present with a high number of circulating lymphocytes, which are also susceptible to lysis.

An extensive literature review demonstrated that the expression Gumprecht shadows gradually lost importance in the CLL diagnosis, as more precise methods were established for that purpose.
