“…Microscopic evaluation of these cholecystectomy specimens revealed extensive mucosal ulceration, mucosal to transmural necrosis, hemorrhage, widespread fibroblastic proliferation, transmural inflammatory cell infiltrate, vasculitis with thrombosis of medium-sized vessels, hemorrhagic infarction of the gallbladder wall, and hypertrophy of nerve fibers. 46,[90][91][92][93][94] Spontaneous perforation of the gallbladder in the setting of COVID-19 has been described in a case of acute cholecystitis; that showed ischemic mucosal necrosis upon microscopic evaluation of the cholecystectomy specimen. 95 SARS-CoV-2 nucleocapsid protein and RNA were demonstrated in the gallbladder wall in 2 studies, one of which was for 2 COVID-19 patients who presented with features of acute acalculous cholecystitis and had a microscopically uninflamed gallbladder.…”
