Abstract
We reported a case of intravascular T-cell lymphoma (T-IVL) with anaplastic large cell morphology, the hemophagocytic syndrome, and an aggressive clinical course. Phenotypic analysis of the tumor cells revealed CD2+, CD3-, CD4+, CD5-, CD8-, CD30+, CD56-, T-cell receptor alpha/beta-, ALK-, TIA1+, granzyme B+, and perforin+. No association with Epstein-Barr virus was found by in situ hybridization. A review revealed that 25 cases of T-IVL have been reported in the available literature, only two of which were of CD30+ anaplastic large cell or cytotoxic T-cell type. The findings in the present case may highlight the unique clinicopathologic aspects of a subset of CD30-positive T-IVLs with an ALK-negative cytotoxic phenotype.
