Inflammatory pseudotumor is a Fare lesion that generally is considered to b
e benign in biological behavior, although some may recur or metastasize. Th
e authors report on a patient with inflammatory pseudotumor of the liver wh
ose preoperative radiologic findings resembled those of focal nodular hyper
plasia. The biological investigation showed a polyclonality of the cells an
d diploidy of the DNA content and suggested benign characteristics of the l
esion. Copyright (C) 2001 by W.B. Saunders Company.
