Overview
Anaplastic large cell lymphoma is an aggressive (fast-growing) type of non-Hodgkin lymphoma that is usually of the T-cell type.[1] The anaplastic large cell lymphoma (ALCL) ALK-positive (Anaplastic Llymphoma Kinase) characterized by the proliferation of CD30-positive T-cells which have an abundant cytoplasm, a pleomorphic nucleus (horseshoe-shaped nucleus), and an eosinophilic paranuclear region.[2]ALK negative ALCL T-cells express CD30, but not the ALK (Anaplastic Lymphoma Kinase) chimeric protein,[3] which explains the difference in clinical outcome compared to that of ALK(+)-ALCL.[4]
