Angioimmunoblastic T-cell lymphoma: a rare subtype of peripheral T-cell lymphoma.

Angioimmunoblastic T-cell lymphoma (AITL) is a rare form of NHL and usually presents in the late stage due to the atypical laboratory findings. Immunohistochemistry of the lymph node in AITL is characterized by positive CD2, CD3, CD4, CD10, CXCL-13, PD1 often BCL-6 and CD20 positive. Meshworks of follicular dendritic cells are seen outside follicles with CD21 and CD23 stains. EBV can be often positive as well. Autologous transplantation should be offered in the first remission as poor outcome is reported with anthracycline-containing regimens.

Blastic plasmacytoid dendritic cell neoplasm.

Blastic plasmacytoid dendritic cell neoplasm is an aggressive neoplasm with a median survival of only a few months despite treatment. An exhaustive immunohistochemical workup is required to differentiate it from myeloid sarcoma and extranodal NK/T cell lymphoma. Treatment is with induction using a regimen utilized for leukemia. Allogeneic hematopoietic stem cell transplantation is recommended for those who achieve remission following induction.
