Morphological Differences Between Promonocyte and Monoblast

Morphological features of promonocytes and monoblasts in a smear: nuclear structure, chromatin condensation, and cytoplasmic characteristics for differential diagnosis.

The correct answer to the problem from the closed club of laboratory hematologists. A and B. Promonocyte — characterized by an indented nucleus with more condensed chromatin compared to a monoblast, with similar sparsely granulated cytoplasm. Material source for the problem: Shauna Anderson - Atlas of Hematology Anderson’s Second Edition, 2013 🏆 Congratulations to the winners!
