ABSTRACTIntroduction: Hepatic choristomas or ectopic livers are extremely rare developmental anomalies that can be found in any part of the body and are usually located in the abdomen, retroperitoneum, and thorax. Clinical case: A 30-year-old female was admitted for laparoscopic cholecystectomy. During surgery, gallbladder stones were found, and a smooth fragment of reddish-brown tissue attached to its anterior surface. The patient evolved satisfactorily and was discharged 24 hours after surgery. Objective: To describe a clinical case of hepatic choristoma adhered to the anterior wall of the gallbladder, its etiology, clinical picture, and therapeutic behavior. Conclusions: Hepatic choristoma of the gallbladder is due to an anomaly during the embryological development of the liver. Due to its potential malignant transformation, it should be readily resected. A laparoscopic cholecystectomy is an adequate approach.
