Smudge cells – include or exclude?

Smudge cells – include or exclude?

Increased focus is placed on the importance of smudge cells in connection with certain types of diagnoses.

A number of articles explore this subject and according to the article Percentage of Smudge Cells on Routine Blood Smear Predicts Survival in Chronic Lymphocytic Leukemia the writers suggest that the number of smudge cells may have important biologic correlations rather than being only an artifact of slide preparation.

Smudge Cells or Basket Cell-A Diagnostic Pitfall reviews that the smudge cells on the film will not be included in manual differential, thereby resulting in an undercounting of the actual lymphocytes present. So education is needed.

This is an interesting discussion and we would … Read more »

Study: Atypical CLL Identified by Digital Microscopy

Study: Atypical CLL Identified by Digital Microscopy

Using digital imaging to identify patients with atypical CLL (aCLL) is feasible, economical, and may provide clinically relevant prognostic information at diagnosis and during periodic monitoring according to a new study by Steven Marionneaux at Memorial Sloan Kettering Cancer Center, New York, NY.

Steven Marionneaux is Manager at the Clinical Hematology Laboratories, Memorial Sloan Kettering Cancer Center, New York, NY.

Some insights from the study include:
27% of CLL cases were morphologically classified as atypical CLL. The aCLL group had a higher prevalence of trisomy 12, unmutated IgVH, and CD38 expression (markers associated with poor prognosis), and a lower prevalence of 13q14 deletion compared to typical CLL.

Traditional microscopic assessment … Read more »

Diagnosis mystery cells case #17: Burkitt’s Lymphoma

Diagnosis mystery cells case #17: Burkitt’s Lymphoma

We are glad to see that you are sharing your suggestions despite the limited information we could present for this case.

The patient was diagnosed with Burkitt’s Lymphoma, a cancer of the lymphatic system that has an especially high incidence in equatorial Africa among children 3 to 16 years of age. The disease is characterized by tumors of the jaw bones and abdomen and is named after Denis Burkitt, who mapped its peculiar geographic distribution across Africa in the 1950s.

There are three main clinical variants of Burkitt’s Lymphoma and they cannot really be distinguished from one another based on microscopic morphology. All types of Burkitt’s lymphoma are characterized … Read more »
