Juvenile psammomatoid ossifying fibroma (JPOF) is a rare, benign, fibro-osseous variant of ossifying fibroma. It exhibits short-term rapid growth and has a high recurrence rate. Herein we describe a case of JPOF of the maxilla that was treated via complete excision utilizing an intraoral approach with immediate reconstruction using an iliac bone graft, in conjunction with a comprehensive review of the literature. A 20-year-old man presented with a mass on his right cheek that he reported had been growing over the last 10 months. In that cheek he had noticed fullness and experienced pressure, tenderness, and fluffiness, with no other ophthalmic or dental symptoms. After clinical, radiological, and histological examinations, the diagnosis was confirmed as JPOF. Surgical excision was performed, followed by immediate reconstruction with an autologous iliac cortical and cancellous bone graft harvested from the right iliac crest under general anesthesia. Good cicatrization of the intraoral surgical wounds and right iliac crest were evident. He was monitored for 6 months after the surgery and exhibited appropriate midfacial contour. There were no signs of recurrence or complications.

에나멜모세포종(ameloblastoma)은 하악부에 드물게 생기는 상피성 종양으로서 치원성(齒原性)의 모든 종양과 낭(囊)의 약 $1\%$를 차지한다. 이들은 서서히 자라는 종양이지만 국소적으로 침습성을 보이고 높은 재발율을 나타낸다. 반면에 원격전이는 드물다. 에나멜모세포종은 방사선에 저항적이라고 알려져 있었기에 드문 경우들외에는 주로 수술적 요법으로 치료되어져 왔다. 그러나 최근에 에나멜모세포종이 방사선에 반응을 보이므로 수술가 병용하거나 방사선치료 단독으로 치료에 쓰일 수도 있다는 보고들이 나왔다. 저자들은 수술후 방사선치료 여부를 결정하기 위해 본 치료방사선과에 의뢰된 2예의 에나멜모세포종 중 1예에서 수술후 방사선치료를 실시하였기에 이들 2예를 문헌고찰과 함께 보고하는 바이다.

Ossifying fibroma is a slow-growing benign neoplasm that occurs most often in the jaws, especially the mandible. The tumor is composed of bone that develops within fibrous connective tissue. Some ossifying fibromas consist of cementum-like calcifications, while others contain only bony material; however, a mixture of these calcification types is commonly seen in a single lesion. Of the craniofacial bones, the mandible is the most commonly involved site, with the lesion typically inferior to the premolars and molars. Ossifying fibroma of the jaw shows a female predominance. Some reports of ossifying fibroma have been published in the literature; however, this report continues the research on this topic by detailing 3 types of ossifying fibroma findings on panoramic radiographs and cone-beam computed tomographic images of 4 patients. The radiographs of the presented cases could help clinicians understand the variations in the radiographic appearance of this lesion.

Hemangioma is a common tumor characterized by the proliferation of blood vessels. Some authorities believe that this lesion is not a true neoplasm, but rather a developmental anomaly or harmatoma. This lesion may be present at any age, but most cases are present at birth or arise at an early age, and the central hemangioma of the jaw is uncommon. The usual radiographic appearance of a hemangioma may have one or more of the following characteristics: a soap-bubble or honey-comb effect with multiloculated cyst like lesions having a fine fibrillar framework visible within them. The roots of teeth mayor may not show resorption. The authors have experienced a case of hemangioma, that occured in anterior mouth floor and Mn.symphysis area cured by means of surgical excision without dysfunction and facial disfigurement.

하악 과두에 발생하는 연골육종은 전세계적으로 매우 드물게 보고되는 질환으로 저자등은 하악골 과두돌기부에 발생한 연골육종을 하악골 상행지 수평골 절단술에 의해 종물을 제거후 A-O reconstruction plate로 재건하고 술후 4년1개월까지 재발의 소견이 없는 양호한 결과를 얻었기에 문헌고찰과 함께 보고하는 바이다.

Calcifying cystic odontogenic tumor (CCOT) is an uncommon benign cystic neoplasm of the jaw that develops from the odontogenic epithelium. Invasion into the maxillary sinus by a CCOT is not a typical, and the recurrence of the cystic variant of CCOT in the posterior maxilla is rare. This report describes a recurrent CCOT occupying most of the maxillary sinus of a 24-year-old male patient. As a treatment, marsupialization was carried out as a means of decompression, and the involved teeth were all endodontically treated. Afterward, surgical enucleation was performed. The size of the lesion continued to shrink after marsupialization, and the maxillary sinus restored its volume. This patient has been followed-up for 3 years after the surgery, and there have not been any signs of recurrence.

Metastatic tumors to the jawbones are an infrequent but not rare phenomenon. The most common site of distant primary tumor metastasis to the jaw bones is the breast. The clinical signs and symptoms, and radiographic appearance of these lesions can be quite variable. In this report, an invasive ductal carcinoma of the breast that metastasized to the whole mandible is presented. The patient's medical history revealed that she had undergone a modified radical mastectomy on the right breast eight years ago.

Metastases to the jawbones are found predominantly in the mandible and are rare in relation to the overall spectrum of oral malignancy. Analysis of the literature shows that the most frequent primary sites are the breast, lung, kidney, thyroid, and prostate. Adenocarcinoma of the mandible, whether primary or metastatic, are usually difficult to diagnose clinically. We report a case illustrating the clinical, radiographic, and histologic findings of a metastatic lung adenocarcinoma of the anterior mandible in a 58-year-old male.

The calcifying odontogenic cyst is rare lesion having features of both cyst and neoplasm. Clinically it frequently occurs in young adult and more frequent in the anterior area of the jaw. Radiographically, this lesion has several radiopaque foci within unilocular or multilocular radiolucency. The authors experienced cystic and neoplastic types of calcifying odontogenic cysts in the anterior area of the mandible in a 16-year-old male and 21-year-old female patients who suffered from pain, swelling and teeth displacemeent on the affected area. And we discussed the clinical, radiological and histopathological features with a brief review of the literatures.

A calcifying epithelial odontogenic tumor (CEOT) was first described as a separate entity in 1955 by Pindborg, and has since been referred to as Pindborg tumor. CEOT is characterized by the presence of squamous-cell proliferation, calcification and amyloid deposits, and accounts for only 1% of all odontogenic tumors. CEOT is a benign, though occasional locally invasive, slow-growing neoplasm. It is located either intraosseously or extraosseously, and is usually associated with an unerupted permanent tooth. A 24 year-old female visited our clinic, presenting with a palatal swelling and intra-oral ulcer. After an incisional biopsy, the lesion was confirmed to be odontogenic tumor. A tumor resection and reconstruction surgery with tongue flap were performed.
