Natl J Health Sci Jan ;2(3):135-7.

Acute lymphoblastic leukemia (ALL), is a lymphoid neoplasm arising from lymphoid progenitors, broadly classified according to lineage into B-cell and T-cell ALL in which T-cell ALL constitutes a small proportion. We are reporting here a case of young female who was diagnosed as T-cell ALL using flow cytometry with acquired trisomy 21, identified on conventional cytogenetics, as a unique finding in this case.
