  • Description: An adenomatoid odontogenic tumor is a rare medical condition. Large tumor (or several) often appears in the maxillae. In a minority of cases, the tumor(s) appear in the mandible. We report on a case of a 24-year-old female diagnosed with a mandibular adenomatoid odontogenic tumor, a giant tumor measuring approximately 22 × 25 × 17 cm. The tumor was located on the side of the mandible, causing facial deformity, malnutrition, and hemorrhaging. We assessed the patient's overall condition, carried out a resection of the tumor and mandible from the right condyle to the left mandibular angle, and reconstructed the mandibular defect with a fibula free flap. After the treatment, the patient was followed up for 1 year, with no recurrence detected over this period. Because adenomatoid odontogenic tumors are benign odontogenic lesions, which are painless and slow-growing, most are surgically removed or treated conservatively. However, the above treatment measures cannot be applied in the case of a giant tumor that causes facial deformity, destroys the entire jawbone, and has complications such as hemorrhaging and malnutrition. After the tumor resection, the defect is still significant. Accordingly, reconstruction using a microsurgical bone flap is an effective method instead. Large adenomatoid odontogenic tumors in the mandible are rare, and treatment cannot follow conventional methods. Accordingly, defect reconstruction after tumor resection is essential. •Adematoid odontogenic tumor (AOT) is a rare disease where large tumors often appear in the maxillae.•AOT rarely be seen in the mandible, this is a very rare case of an enormous AOT•In this case, reconstruction of the bone defect immediately after excision was required.•A different approach with mandibular amputation and reconstruction with fibula free flap was successful.
