We report a case of Burkitt lymphoma with largely extranodal disease localizations at staging. Chemotherapy was given, thus obtaining a complete metabolic response in all previous disease sites as shown at a control PET, however associated to the appearance of new focal uptake areas in the liver; these findings were confirmed at US and MRI. Chemotherapy determined also neutropenia that was treated by filgrastim, followed by a prompt and important medullary response. Liver biopsy revealed extramedullary hematopoiesis, probably filgrastim induced. Filgrastim administration may cause false-positive findings in the liver at FDG PET.

The Li-Fraumeni cancer predisposition syndrome (LFS1) presents with a variety of tumor types and the TP53 gene is covered by most diagnostic cancer gene panels. We demonstrate that deleterious TP53 va...
Cancer progression is associated with alterations of intra- and extramedullary hematopoiesis to support a systemic tumor-promoting myeloid response. However, the functional specialty, mechanism, and c...
The Baveno VI Consensus recommends repeating examination in patients with high liver stiffness measurement (LSM) by transient elastography to reduce false-positive diagnosis of advanced liver disease....
Acute liver failure of all causes is diagnosed in between 2000 and 2500 patients annually in the United States. Drug-induced acute liver failure is the leading cause of acute liver failure, accounting...
This study will describe the time point at which a positive culture from a patient who has undergone shoulder surgery should be treated as an infection versus a false positive result that ...
A prospective study will be performed to compare the clinical outcome after total knee arthroplasty (TKA) using two different alignment systems: an extramedullary system versus an intramed...
Filgrastim is a Granulocyte-Colony Stimulating factor (G-CSF). It is an FDA approved drug. Very small embryonic-like stem cells (VSELs) are found in the ovary. Animal studies showed that t...
This is a multi-center, open-enrollment, retrospective, non-interventional epidemiologic study without any clinical treatment. Its primary objective is to understand 1) incidence of drug-i...
Viral infections can profoundly influence alloimmune responses and hamper allograft tolerance induction. Persistent hepatitis C virus (HCV) infection occurs in 50% of liver and 20% of kidn...
The development and formation of various types of BLOOD CELLS. Hematopoiesis can take place in the BONE MARROW (medullary) or outside the bone marrow (HEMATOPOIESIS, EXTRAMEDULLARY).
The formation and development of blood cells outside the BONE MARROW, as in the SPLEEN; LIVER; or LYMPH NODES.
Excessive formation of dense trabecular bone leading to pathological fractures; OSTEITIS; SPLENOMEGALY with infarct; ANEMIA; and extramedullary hemopoiesis (HEMATOPOIESIS, EXTRAMEDULLARY).
A myeloproliferative disorder of unknown etiology, characterized by abnormal proliferation of all hematopoietic bone marrow elements and an absolute increase in red cell mass and total blood volume, associated frequently with splenomegaly, leukocytosis, and thrombocythemia. Hematopoiesis is also reactive in extramedullary sites (liver and spleen). In time myelofibrosis occurs.
Positive test results in subjects who do not possess the attribute for which the test is conducted. The labeling of healthy persons as diseased when screening in the detection of disease. (Last, A Dictionary of Epidemiology, 2d ed)
Hepatology is the study of liver, gallbladder, biliary tree, and pancreas, and diseases associated with them. This includes viral hepatitis, alcohol damage, cirrhosis and cancer. As modern lifestyles change, with alcoholism and cancer becoming more promi...
