Anaplastic Large Cell Subtype of Adult T-cell Leukemia/Lymphoma (ATLL)
The malignant cells express IL2 receptor α (CD25), and the majority express transcription factor Forkhead box P3 (Foxp3), in addition to T-cell markers. Occasional cases express CD30.
Whereas Japanese cases are predominantly of the acute and chronic leukemic types, the less well-studied Caribbean cases are more often lymphomatous.
Foxp3 expression correlates with pleomorphic small and medium cell types and may be lost with large cell transformation.
