Laparoscopic cholecystectomy for acalculous, gangrenous cholecystitis on an outpatient COVID-19 adult: a case report.

We report the rare case of an acalculous, gangrenous cholecystitis on a, previously healthy, outpatient COVID-19 adult. The 53-year-old patient presented to the emergency department due to epigastric pain and fever and was admitted to the COVID-19 department. Due to clinical and laboratory deterioration, a computed tomography scan was performed that confirmed the diagnosis of acalculous cholecystitis. The patient was submitted to laparoscopic cholecystectomy. Intraoperatively, a gangrenous gallbladder was identified. Immunohistology validated the presence of specimen wall vasculitis and vessel thrombosis.
