Infectious mononucleosis in an adult progressing to fatal immunoblastic lymphoma
Abstract:
We report a case of infectious mononucleosis progressing to fatal immunoblastic lymphoma. The patient, a 44-year-old man who may have had an immunoregulatory defect, failed to have an appropriate T-cell response to his Epstein-Barr (EB) viral infection. His active EB viral infection was manifest by seroconversion of IgM-viral capsid antibody and a greater than four fold rise in IgG-viral capsid antibody. Also, he transmitted his EB viral infection to his wife who became ill 1 month after his death. Clinically the patient's illness was characterized by waxing and waning lymphadenopathy, persistent fever, diarrhea (similar to that associated with cholera), a coagulopathy, and gastrointestinal bleeding. The patient had pathologic findings of a diffuse immunoblastic lymphoma involving lymph nodes, small bowel, liver, pancreas, kidneys, lungs, and bone marrow. Immunologic cell markers showed the tumor to be polyclonal.

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
Disorders of Leukocytes
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune system...
