Intracellular Rod Crystals in Chronic Lymphocytic Leukemia
Background:
So far, rare cases of B cell lymphoproliferative diseases with rod crystals inclusions had been reported.
Methods:
Wright's stain and MPO stain are used for cell and rod crystal staining while the immunophenotype examination, fluorescence in situ hybridization probes, routine G-band cytogenetic analysis and molecular biological tests are used to diagnose the disease which is chronic lymphocytic leukemia.
Results:
One to six colorless rod-like crystals can be seen in some mature lymphocytes of the peripheral blood smear and also colorless by MPO staining. The immunophenotype examination with flow cytometry shows it is consistent with chronic lymphocytic leuke mia/B small lymphocytic lymphoma.
Conclusions:
The discovery of this rare phenomenon of rod-shaped crystallization in the peripheral blood may contribute to the diagnosis of lymphoproliferative diseases in B cells.

Lymphoid cells consist of various types of immune system cells. These include B and T lymphocytes, which are responsible for producing antibodies and killing infected cells, respectively. Dendritic cells act as messengers between the innate and adaptive...
01:27Disorders of Leukocytes
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune...
