Abstract

Here we present a 40-yr-old male patient with an aggressive B-cell lymphoma, who presented 2 yr earlier with polyarthritis, and was responsive to steroids and oral methotrexate. Thereafter he developed skin and lung lesions which on biopsy consisted of mixed 'inflammatory' infiltrates with granulomatous vasculitis. A diagnosis of seronegative Wegener's granulomatosis was made and the patient received a combination of prednisone and cyclophosphamide with clinical improvement and clearance of the radiological lesions in the lungs. The patient was now completely asymptomatic for 1 yr, but then generalized lymphadenopathy appeared, which was shown by histopathology to be large B-cell lymphoma, also involving the bone marrow. Despite intensive chemotherapy, his disease could not be controlled because of primary chemoresistance, which was perhaps in some way related to exposure to the suboptimal doses of chemotherapy given during the 'inflammatory' period before the diagnosis of lymphoma was established. This case illustrates the occasional difficulty in distinguishing between extranodal lymphoproliferative diseases and autoimmune disorders especially when clonality cannot be proved. It also shows the possible risk of 'masking' a tru...Continue Reading

Autoimmune Diseases

Autoimmune diseases occur as a result of an attack by the immune system on the body’s own tissues resulting in damage and dysfunction. There are different types of autoimmune diseases, in which there is a complex and unknown interaction between genetics and the environment. Discover the latest research on autoimmune diseases here.

Autoimmune Lymphoproliferative Syndrome

Autoimmune lymphoproliferative syndrome (ALPS) is a rare genetic disorder of abnormal lymphocyte survival caused by defective Fas mediated apoptosis. Discover the latest research on ALPS here.

B-Cell Lymphoma

B-cell lymphomas include lymphomas that affect B cells. This subtype of cancer accounts for over 80% of non-Hodgkin lymphomas in the US. Here is the latest research.
