From: Nerve pathologic features differentiate POEMS syndrome from CIDP
Cross section (a and c) and longitudinal (b and d) paraffin section stained with H&E showing inflammatory infiltrates in POEMS and CIDP biopsies. In POEMS biopsies, the inflammation was mostly epineurial perivascular (a and b) whereas in CIDP the inflammation was endoneurial perivascular (c) and epineurial perivascular (d)
