Plasma cell leukaemia masquerading as hairy cell leukaemia: a case report

Plasma cell leukemia: A case series from South India with emphasis on rarer variants

Plasma cell leukemia (PCL) is a rare and aggressive variant of plasma cell dyscrasia. They occur de novo (primary) or as a late manifestation of multiple myeloma (secondary). Patients present with anemia, thrombocytopenia, renal failure, organomegaly and extramedullary manifestations. We are presenting this series as it is the second largest series from India (16) with 4 young cases (under 40 years of age), more number of female patients and two having ‘hairy cell’ morphology. It is recommended that techniques like immunophenotyping and protein electrophoresis be performed, whenever the morphology is not characteristic of plasma cells.
