Original MICA image-reading exercise, unscored. No clinical narrative absent from the source is added.
- Describe visible findings before proposing an interpretation.
- Suggest an interpretation and at least one image limitation.

Morphological description
Describe size, chromatin, nucleoli, cytoplasm and uniformity; distinguish intact cells from disrupted cells.
Causes and diagnostic direction
Infection-related reactions and lymphoid proliferation are possible; persistence and morphology guide interpretation.
Differential diagnoses
A uniform mature population may suggest proliferation without independently establishing its nature or clonality.
Pitfalls and limitations
Smudge cells alone do not establish diagnosis; preparation and cellular fragility affect appearance.
Take-home message
Describe findings and correlate counts and appropriate testing; the case diagnosis remains an attribution from its source.
