Gy. Lauwers et al., PAPILLARY MUCINOUS ADENOMA ARISING IN ADENOMYOMATOUS HYPERPLASIA OF THE GALL-BLADDER, Journal of Clinical Pathology, 48(10), 1995, pp. 965-967
A case of papillary mucinous adenoma arising in adenomyomatous hyperpl
asia (AMH) of the gall bladder is reported. The lesion was unsuspected
and discovered by routine palpation of the gallbladder during laparot
omy. The adenoma developed within fundal AMH and showed cytological at
ypia. This case illustrates that neoplastic proliferation is indeed po
ssible in AMH and challenges the classical opinion that AMH is devoid
of neoplastic potential.
