23
Q

Reactive lymphocyte morphology

A

Nucleus - oval, notched, indented or elongated; may be “soft” and intended by adjacent RBCs
Chromatin - irregular, variable clumping and staining intensity, parachromatin more apparent
Nucleoli - 1 or more may be visible, large
Cytoplasm - Increased volume, irregular staining, edges dark and scalloped
May have vacuoles or azurophilic granules

24
Q

Reactive neutrophil morphology

A
Basophilic cytoplasm
Toxic granulation
Doyle bodies
Vacuolization
Hyper segmentation
