Primary papillary hyperplasia of the gallbladder mimicking gallbladder cancer.

Primary papillary hyperplasia of the gallbladder (PPHG) is a rare entity. PPHG is a benign diffuse mucosal projection without any background chronic inflammation-related disease of the gallbladder or bile ducts. Reported cases of PPHG are limited in that its characteristics are not well defined. We herein report a case of PPHG mimicking gallbladder cancer in radiologic investigations and present a review of the literature. Also coincident erythroderma is discussed.
