RARE CASE OF CD10+CD23+ HAIRY CELL LEUKEMIA WITH LEUKOCYTOSIS. CASE REPORT AND LITERATURE REVIEW.
A rare case of hairy cell leukemia with CD10+CD23+ expression and leukocytosis is described. The key point marker for hairy cell leukemia is the presence of the BRAF V600E mutation regardless of the leukocyte count and atypical aberrant CD10+ or CD23+ expression. The presented clinical case report is important for understanding the biology of hairy cell leukemia and emphasizes the role of molecular genetic testing in atypical morpho-phenotyping disease presentation.
