[Primary plasma cell leukemia: about 3 cases].

Area of Science:

• Hematology
• Oncology
• Clinical Pathology

Background:

• Plasma cell leukemia (PCL) is a rare hematologic malignancy.
• It is defined by over 20% plasma cells in the leukocyte count or >2 × 10^9/L circulating plasma cells.
• PCL can be primary (60%) or secondary to multiple myeloma (40%).

Observation:

• This study presents three cases of PCL diagnosed at Mohamed V Military Hospital.
• The rarity of PCL limits the available case reports and clinical data.
• The condition is known for its aggressive nature and poor prognosis.

Findings:

• The study aims to describe the clinical, biological, and prognostic characteristics of PCL.
• Analysis of these three cases will contribute to understanding PCL's presentation and progression.
• Detailed case information will aid in characterizing this rare leukemia.

Implications:

• Understanding PCL's features is crucial for timely diagnosis and treatment.
• Further research into PCL is needed due to its aggressive nature and poor outcomes.
• This case series adds valuable data to the limited literature on plasma cell leukemia.
