Airway Management: A Case of Desmoplastic Ameloblastoma of Right Mandibular Body

Background- Desmoplastic ameloblastoma (DA) is an uncommon variety of ameloblastoma that accounts for 4–13% of all cases, with notable differences in anatomical location, imaging, and histologic appearance. It is classified as a variety of ameloblastoma in the WHO classification of head and neck tumours (WHO-2005). Because it commonly occurs in the anterior region of the jaws as a mixed radio-opaque-radiolucent lesion, the tumour resembles a benign fibro-osseous lesion.
 Case report- We present a case of desmoplastic ameloblastoma in a 51-year-old female with a painless swelling in the lower right region of mandible. Fine needle aspiration revealed no fluid. Both panoramic radiographs and a computed tomography scan revealed a mixed lesion with a multilocular appearance. Desmoplastic ameloblastoma was confirmed after an incisional biopsy. From teeth 41 to the angle of the jaw, a composite resection of the lesion was performed with segmental mandibulectomy. With a peek implant, it was repaired. The possibility for a problematic airway is emphasised in this case, with great surgical results.
 Conclusion: Desmoplastic ameloblastoma is a kind of ameloblastoma with unique clinic radiographic and histologic characteristics. Despite its rarity, the tumour necessitates a thorough examination due to the challenges it poses with airway ventilation and intubation.

Desmoplastic Ameloblastoma with Prominent Osteoplasia (Osteoplastic Ameloblastoma) as a Recurrence after 14 Years: A Case Report and Literature Review

Background: Ameloblastoma is the most common odontogenic tumor arising from the odontogenic epithelium and is known for its distinct aggressive clinical behaviour and characteristic histologic picture. Very few cases of desmoplastic ameloblastoma with prominent osteoplasia (osteoplastic ameloblastoma) exhibiting formation of metaplastic bone trabeculae rimmed by active osteoblasts have been described. Case Presentation: We report an interesting case of desmoplastic ameloblastoma with prominent osteoplasia (osteoplastic ameloblastoma) in a 38-year-old male presented as a recurrence after 14 years in the anterior mandible. Conclusion: A hybrid lesion of desmoplastic ameloblastoma with osteoplastic pattern (osteoplastic ameloblastoma) needs inclusion of new cases to understand their behaviour. Recurrence of lesion after 14 years of initial surgery in our case presents the importance of regular bi-annual follow-up for lifetime.

Desmoplastic ameloblastoma: a case report.

Desmoplastic ameloblastoma is a rare variant of ameloblastoma. Up until now, less than 150 patients have been reported in the literature. We report a case of desmoplastic ameloblastoma in a 45-year-old female with a painless swelling in the left anterior maxillary region. Fine needle aspiration yielded no fluid. Periapical and panoramic radiographs as well as computer tomography scan showed a mixed lesion with multilocular appearance. The present case deserves special importance be-cause of its unfamiliar appearance, potentially aggressive nature and high chances of misdiagnosis. Moreover, the radio-graphic features of this lesion rarely point towards ameloblastoma. A partial maxillectomy for tumor resection was per-formed and the involved teeth were removed. This report is an attempt to help the dental community in developing familiarity with the clinical presentation and at the same time advocating to develop a high index of suspicion in recognizing such cases.

A case of desmoplastic ameloblastoma is reported. The patient was a 77-year-old woman, who visited our hospital because of painless expansion of the anterior region of the mandible. Radiograms and CT scans revealed a mixed radiolucent-radiopaque lesion, which was poorly defined and associated with large cystic radiolucent areas. The lesion was excised, followed by the curettage of the underlining intact bone, under general anesthesia. Histologically, the lesion was composed of enamel organ-like tumor nests scattered in prominent fibrous connective tissue. Some tumor nests showed microcyst formation and transition to larger cysts. TGF-β was strongly expressed especially by tumor cells at the periphery of tumor nests, unlike conventional types of ameloblastomas. The postoperative course has been uneventful for 6 months. Clinical and radiographic characteristics of this tumor are discussed.
