Here, we describe a case presenting in the mandible as an acute swelling of the cheek, which was initially misdiagnosed as osteomyelitis resulting in a delay to definitive surgical treatment. The cause of misleading diagnosis is often owing to the rapid growth of the lesion, sometimes associated with painful soft tissue swelling indicating an infectious origin or a malignant tumor. Magnetic resonance imaging revealed the classic characteristics of aneurysmal bone cyst with severe destruction of the mandible. Therefore, curative tumor embolization and complete surgical excision was successfully performed. The aneurysmal bone cyst is a curable condition by radical excision, although relapse may occur when only incomplete excision is obtained. Therefore, aneurysmal bone cyst should be considered early when children present with unusual, rapid-growing neoformations of the extremities or the facial region.

  Abstract Adenomatoid odontogenic tumor (AOT) is a rare odontogenic tumor which is often misdiagnosed as odontogenic cyst. To acquire additional information about AOT, all reports regarding AOT andAbstract Adenomatoid odontogenic tumor (AOT) is a rare odontogenic tumor which is often misdiagnosed as odontogenic cyst. To acquire additional information about AOT, all reports regarding AOT and cited in "pubmed" since 1990 onward were reviewed. AOT accounts for about 1% until 9% of all odontogenic tumors. It is predominantly found in young and female patients, located more often in the maxilla in most cases associated with an uneruppted permanent tooth. For radiological diagnose the intraoral periapical radiograph seems to be more useful than panoramic. However, AOT frequently resemble other odontogenic lesions such as dentigerous cysts or ameloblastoma. Immunohistochemically AOT is characterized by positive reactions with certain cytokeratins. Treatment is conservative and the prognosis is excellent. For illustration a rare case of an AOT in the mandible is presented.
