ABSTRACT
Unicystic ameloblastoma is a slow-growing tumor originating from the odontogenic epithelium that can be localized within the lining of a cyst. It commonly affects younger individuals and is frequently found in the posterior mandible. The classification of this tumor is based on histopathological characteristics, distinguishing between the luminal, intraluminal, and mural proliferation of the odontogenic epithelium. Treatment options vary depending on the histology and can range from enucleation to resection with secondary reconstruction. In recent years, patient-specific implants have gained popularity in reconstructive surgeries, particularly in craniomaxillofacial surgery. This case report focuses on a 22-year-old female patient with a mural-type unicystic ameloblastoma. The treatment involved segmental mandibular resection with primary reconstruction using a patient-specific implant to address the mandibular defect. The postoperative healing process and condylar movement were evaluated, and the patient achieved satisfactory results. This case report provides valuable insights into the management of primary reconstruction using a patient-specific implant.
ABSTRACT
Massive cystic lesions involving a mandible always present a diagnostic and treatment challenge. Unicystic ameloblastoma (UA) is a variant of ameloblastoma encompassing about 6% of ameloblastomas. They represent cystic lesions that reveal clinical and radiographic features of a cyst, but the histopathological features demonstrate a typical ameloblastomatous epithelium lining the cyst. It is a variant of ameloblastoma, usually having clinical and radiographic similarities with dentigerous cysts, hence posing preoperative diagnostic difficulties. Adult treatment protocol cannot be applied to the pediatric population since resection may cause an alteration in craniofacial development leading to functional and esthetical damage, which can directly affect their quality of life. A more conservative approach of enucleating the lesion seems to be a promising treatment modality of UA in the pediatric age group. We present a case of mural variant of UA arising from dentigerous cyst in an 8-year-old male patient.
ABSTRACT
Unicystic ameloblastoma is considered a less aggressive variant of ameloblastoma with clinical and radiographic features mimicking a cyst. Herein, we present a case of unicystic ameloblastoma in a 20-year-old female who was clinically and radiographically diagnosed as an odontogenic cyst. Unicystic ameloblastoma and its subtypes are reviewed with special emphasis on the mural variant. The main aim of this case report is to highlight (1) the need of including an odontogenic tumor in the differential diagnosis of the unilocular, well-circumscribed radiolucent lesion by the clinicians (2) importance of serial sectioning of the specimen to identify the mural component if any present, and (3) following resection as the mode of treatment.
ABSTRACT
Unicystic ameloblastoma (UA) differs from conventional ameloblastoma by presenting in the younger population with a lower recurrence rate and has a unilocular appearance on radiograph mimicking dentigerous cysts. Among the three variants of UA, the mural variant has a tendency to recur. Here we present a case of mural variant of UA in a pediatric patient treated conservatively with enucleation followed by application of Carnoy's solution to the cystic cavity. The aim of this case report is to emphasize conservative management in the treatment of UA in pediatric patients considering growth and development in children.
