CD30, a non-death domain-containing member of the tumor necrosis factor receptor superfamily, triggers apoptosis in anaplastic large cell lymphoma cells. The CD30 signaling pathways that lead to the induction of apoptosis are poorly defined. Here, we show that the induction of apoptosis by CD30 requires concurrent inhibition of p38 mitogen-activated protein kinase, which itself is activated by ...

Lymphoma is a well-known complication of HIV infection. Such AIDS-defining lymphomas are usually aggressive B-cell lymphomas. However, epidemiological data have also linked HIV infection with an increased risk of T-cell lymphoma.1 Therefore, it is easy to appreciate why the number of AIDS-related T-cell lymphoma case reports has increased in the literature.2 We present an interesting case of fa...

Anaplastic large cell lymphoma with a small cell pattern is a rare T-cell lymphoma. This condition is more frequently seen in younger patients and should be considered when patients present with leucocytosis and constitutional symptoms. In this report, we describe our diagnostic work-up for one such case using blood, lymph node, and bone marrow aspirate samples, highlighting the variability of ...

AIDS-related malignancies may alter clinical courses and result in death in critically ill patients. We present a case of a newly diagnosed AIDS patient with Pneumocystis jiroveci pneumonia, Epstein-Barr virus, and cytomegalovirus infections who was found to have widely metastatic kinase-negative anaplastic large-cell lymphoma. This case demonstrates the diversity in the malignant presentation ...
