CD34 and reticulin!Oldies, but goodies!

CD34 in HCC – always complete and diffuse

CD34 in HCC – always complete and diffuse

CD34 in HCA – usually incomplete or “patchy”

A CASE:44 y.o. obese man with 5 cm liver tumor

(“incidental” on imaging for other reason); MRI showed typical diagnostic HCC features in a

central part of the tumor. Underwent chemoembolization with NO response.

Decision to resect.

DX: Inflammatory HCA

ANOTHER (PROBLEM!) CASE

Features:Fibrous stroma

Ductular reactionsInflammation

Could be FNH orInflammatory HCA

Features:Sinusoidal dilatation and

congestion.

Suggests Inflammatory HCA?

Glutamine SynthetaseAppears relatively normal distribution in original biopsy

C-reactive protein

C-reactive proteinAppears widespread in the lesional pieces of tissue

C-reactive protein

Inflammatory HCA

vs.

Focal Nodular Hyperplasia

?

Relatively normal GS + Diffuse, strong CRP = ?

Inflammatory HCA

vs.


?

Relatively normal GS + Diffuse, strong CRP = iHCA

Inflammatory HCA

vs.


?

Relatively normal GS + Diffuse, strong CRP = iHCA

SO THE TUMOR IS RESECTED, BECAUSE I TOLD THEM TO!

BUT!!!!Resected lesion the GS appears to be

“Map-like” as seen in FNH and the C-reactive protein not evenly

distributed, so not I-HCA
