Introduction and importance: Ectopic liver tissue is an exceedingly rare anomaly in which the hepatic tissue is present extrahepatic site and has no connection to the true liver. Most cases of ectopic liver tissue were asymptomatic and discovered by an accident during abdominal surgery or autopsy. Case presentation: Case 1 involved a 52-year-old man who was admitted to the hospital due to an abdominal grip in the right hypochondrium and epigastrium for 1 month. The patient underwent laparoscopic cholecystectomy. During the gross examination, a well-circumscribed brownish nodule with a smooth outer surface, located at the fundus region was found. Case 2 involved a 40-year-old man with 2 months history of epigastric pain radiating to the right shoulder. Calculus chronic cholecystitis was diagnosed by ultrasound. The patient undergoes elective laparoscopic cholecystectomy. A gross inspection showed a small nodule attached to the serosa of the gallbladder. Microscopically, both cases revealed ectopic liver tissue. Clinical discussion: Ectopic liver tissue is an uncommon entity that occurs during the embryological development of the liver and can be found below and above the diaphragm, especially the gallbladder. Histologically, it usually has the normal architecture of the liver. Although ectopic liver tissue is an exceptional finding, pathologists should be aware of it because it has a high risk of transformation into malignancy. Conclusion: Hepatic choristoma is a rare failure of embryological liver development. It should be removed when recognized and examined histologically to rule out malignancy.

Introduction: Intussusception is a common finding among children. Conversely, it is infrequent in adults. Colonic lipomas are generally clinically silent making them a very rare etiology of intussusception. Presentation of case: The authors present a case of a 48-year-old male who presented to the emergency department suffering from severe abdominal pain. Following examination and investigations, a giant lipoma (GL) in the transverse colon was identified via ultrasound which showed the classical “target sign”. Clinical discussion: Intussusception among adults is unusual as it accounts for only 1% of bowel obstruction cases. Being colo-colonic makes it even more unlikely since it occurs only in 17% of intestinal obstruction cases. GLs exceeding 5 cm in size can present with a variety of symptoms. Intussusception is an uncommon presentation of a GL. Preoperative diagnosis of GL-induced intussusception is highly improbable and surgical resection is the treatment of choice. Conclusion: Despite the dominance of the asymptomatic presentation of lipomas, considering its diagnosis in the case of an intussusception-induced acute abdomen should cross physicians’ minds.

Introduction: The odontogenic myxoma is a tumor of the jaws which arises from the mesenchymal portion of the tooth germ, either the dental papilla, the follicle, or the periodontal ligament. It is a slow-growing, painless, nonmetastasizing, central tumor of the jaws, chiefly the mandible. Radiographically, the classic presentation may vary from a unilocular radiolucency to a multilocular lesion with well-defined or diffuse margins. On histological study, it is composed of triangular or stellate connective cells, anastomosed by fine extensions, and embedded in abundant mucoid material. Case presentation: We present the unusual case of an odontogenic myxoma involving a 37-year-old female patient, which had acquired large dimensions and involved the right half of the mandible, including the ramus; the patient was treated with large resection surgery, with satisfying medium-term results. Clinical discussion: Early diagnosis of such lesions is very important, as the patient avoids extensive surgical procedures that involve losing a large part of the jawbones and their subsequent impact on the patient’s quality of life. Conclusion: Although there is no fixed treatment plan for the management of odontogenic myxoma, treatment includes surgical management that may range from simple enucleation and curettage to surgical excision; wide surgical resection is appropriate for cases of large size to avoid recurrence.

Ectopic adrenal tissue (EAT) is an extremely unusual finding. The most common site is the genitourinary tract and pelvis, and more frequently in males than females. In our report, we discuss an ectopic adrenal cortical tissue detected in the descending mesocolon in an elderly female. To the best of our knowledge, this case is the first report in the English literature.
