In face of the ambiguous use of the term Gumprecht shadows in clinical situations of distinct prognosis and evolution, it would be quite pertinent to keep using it in cases of CLL, principally knowing that absolute lymphocytosis in peripheral blood is not always a sign of malignancy.

On the other hand, in lymphomas, although cells express B-lymphocyte and CD5 surface antigens, they normally do not express CD The expression Gumprecht shadows historically refers to lymphocyte lysates commonly observed in patients with chronic lymphocytic leukemia CLL.

Since the presence of viroses may cause the appearance of images similar to those observed in CLL because of lymphocyte lysis, a literature review was undertaken by searching the word Gumprecht referring to images of lymphocyte lysates that occur in viral diseases. More sophisticated techniques are required for the proper classification In a web search engine commonly used to qtlas doubts on medical terms, there are countless pages where Gumprecht shadows are associated with CLL.

CLL is suspected when the blood film reveals an expressive increase in uniform-appearing lymphocytes and the presence of destroyed lymphocytes.

Besides, serum determination of lactate dehydrogenase LDHbilirubin, immunoglobulins, and antiglobulins composes the test panel currently used to diagnose CLL 6. A search in the PubMed database using terms Gumprecht chronic lymphocytic leukemia revealed just five reports 4, 12, 13, 36, 37what confirms that the term has fallen into disuse.

It is benign in comparison to other leukemias, shows slow evolution and marked leukocytosis in the blood The World Health Organization WHO describes CLL as a neoplasm of small B lymphocytes, with slightly irregular membrane present in peripheral blood, bone marrow, spleen and lymph nodes, along with prolymphocytes and paraimmunoblasts that proliferate in the infiltrated tissues CLL is a relatively rare lymphoproliferative disorder. The expression Gumprecht shadows must be used only for cases of CLL, not to describe ruptured lymphocytes present in other situations with lymphocytosis, associated with either viral diseases or other causes.
