Key Clinical Message: Giant pedunculated hepatic hemangiomas, mostly seen in women, are considered a rare type of giant hepatic hemangioma, with challenging diagnosis. Unlike other types of liver hemangiomas, they can manifest different kinds of symptoms, and are prone to life-threatening manifestations like rupture or torsion., Abstract: Hemangioma is the most common benign liver primary tumor. Hepatic hemangioma >4 cm (some studies suggest >10 cm) is referred to as a giant hemangioma. Although hepatic hemangioma does not manifest symptoms in most cases, a giant hepatic hemangioma can manifest different kinds of symptoms. Giant pedunculated hepatic hemangiomas are considered a rare type of giant hepatic hemangioma, with challenging diagnosis, as the thin pedicle could be hard to be detected on imaging. A 41-year-old woman was admitted to our hospital, with dull discomfort of the right upper quadrant and epigastric region and early satiety for the past 7 months, with the history of taking oral contraceptive (OCP) for 10 years. Ultrasound and computed tomography revealed a 130 × 124 × 76 mm solid mass, with central cystic lesion, located in the midline of the epigastric region, attaching to the inferior surface of the third segment of the left lobe of the liver. Due to the potential risk for torsion, and rupture of the hemangioma, the management of the patient proceeded to surgical excision. Pathological examination of the specimen confirmed the diagnosis of hepatic hemangioma. Giant pedunculated hepatic hemangioma is a rare benign tumor. It demonstrates higher incidence rate in women, as some hemangiomas have estrogen receptors, and estrogen can lead to endothelial cell proliferation and organization in vascular structure. Most hemangiomas do not express any symptoms; therefore, no treatment is needed except for the patients who manifest symptoms, or in giant pedunculated hemangiomas, as they are prone to rupture or torsion. In this review most cases were female, and most of them presented with abdominal pain, in most cases the tumor located in the left lobe of the liver. Almost all the reviewed cases underwent surgery. Giant hepatic hemangioma is a differential diagnosis of palpable mass, or other symptoms of the right upper quadrant, and epigastric region specially in women taking OCP. Imaging is needed to rule out these tumors, and most often, pedunculated hemangioma is harder to be defined on imaging. It requires surgery because of the risk of acute problems, such as torsion and rupture., (© 2024 The Author(s). Clinical Case Reports published by John Wiley & Sons Ltd.)

Introduction: Calcifying odontogenic cysts (COC) are rare lesions classified as developmental cysts and occur mostly in the maxillary and mandibular bone. Some of the COCs are related to odontogenic lesions., Case Presentation: We report a 60-year-old man with COC of the maxillary bone, presenting after tooth extraction. The patient has a palpable tender mass at the right upper tooth area. Imaging shows a well-defined radiolucency in the 7-3 tooth area of the right upper jaw. The combination of radiologic data and histopathologic findings was in keeping with the calcifying odontogenic cyst. Total enucleation is the chosen treatment for COC. No recurrence is proved by X-ray imaging after 1-year follow-up., Discussion: COC is a rare entity of odontogenic cysts and needs an exact diagnosis by pathology examination to estimate behavior., Conclusion: Our case report offers significant data that could help clinicians and surgeons as well as pathologists with the diagnosis and management of these lesions., Competing Interests: Conflict of interest statement None., (Copyright © 2023 The Authors.
