We have experienced one case of hemoptysis which developed from both upper lung fields due to pulmonary aspergilloma combined with pulmonary tuberculosis. A 48 year old female patient was admitted with 10 years history of recurrent hemoptysis. Chest X-ray film revealed moderately advanced active pulmonary tuberculosis lesion on both upper lung fields, and cresentic radiolucent space between cavity wall and round radiopaque lesion on left upper lung field. Bronchial arteriogram showed hypervascularity and extravasation of contrast media in the right lung and it was treated by bronchial artery embolization. Hemoptysis recurred 7 months after embolization and repeat examination revealed greatly increased bronchial vasculature in the left upper lobe and therefore underwent left upper lobectomy. The pathologic result was compatible with aspergillosis, and the postoperative recovery was uneventful.

We report a case of a 67-year-old woman with giant cell tumor of the temporal bone. A 67-year-old woman presented with localized tenderness, swelling, sensory dysesthesia, dizziness, and headache over the left temporal bone. She was neurologically intact except left hearing impairment, with a nonmobile, tender, palpable mass over the left temporal area. A brain computed tomography(CT) scans showed a relatively well defined heterogenous soft tissue mass with multiple intratumoral cyst and radiolucent, osteolytic lesions involving the left temporal bone. The patient underwent a left frontotemporal craniotomy and zygoma osteotomy with total mass removal. Permanent histopathologic sections revealed a giant cell tumor. She remains well clinically and without tumor recurrence at 2 years after total resection.

Keratocystic odontogenic tumor (KCOT) is a benign odontogenic tumor with a potentially aggressive and infiltrative behavior. KCOT is most commonly occurred in mandible and demonstrate a unilocular, round, oval, scalloped radiolucent area, while large lesions may appear multilocular. An important characteristic of KCOT is its propensity to grow in an antero-posterior direction within medullary cavity of bone causing minimal expansion. Definitive diagnosis relies on histological examination. In this report, a KCOT that had an expansion both buccal and lingual cortical bone is described including its features in computed tomography and ultrasonographic exams. The lesion was removed surgically via an intraoral approach under local anesthesia and histologically reported as a KCOT.

Common radiographic appearances of ossifying fibroma (OF) are well demarcated margin, radiolucent or mixed lesion. Lesions for the radiographic differential diagnosis with OF include fibrous dysplasia, focal cemento-osseous dysplasia. Other confusing lesions might be the mixed lesions such as calcifying odontogenic cyst, adenomatoid odontogenic tumor, calcifying epithelial odontogenic tumor, and benign cementoblastoma. We reported three cases of OF in posterior mandible. These cases showed a little distinguished radiographic features of OF and diagnosed from a combination of clinical, radiographic, and histopathologic information. We need to further refine radiographic and histopathological features of OF and other confusing lesions with literatures review because some cases of these lesions are not easily differentiated radiographically and histopathologically.

Mandibular bone depression, also known as Stafne bone cavity, is defined as a bone depression filled mainly with salivary gland tissue. Parotid gland bone defects are infrequently observed. We report the case of a 52-year-old male patient who underwent radiographic examinations due to temporomandibular joint dysfunction, and a radiolucent area was detected in the mandibular ramus, with a provisional diagnosis of traumatic bone cyst or parotid mandibular bone defect. The patient was then referred for magnetic resonance imaging, which demonstrated a hyperintense area eroding the mandibular ramus, which corresponded to glandular tissue. Although the defect was a benign lesion, radiolucencies in the mandibular ramus lead to concerns among professionals, because their radiographic features can resemble various intrabony neoplastic lesions, such as giant cell tumors or benign tumors of the parotid gland.

The glandular odontogenic cyst (GOC) is a rare cyst derived from odontogenic epithelium with a spectrum of characteristics including salivary gland features. It occurs more commonly in the mandible and most often in the anterior mandible. Radiographically, most cases present a well-defined unilocular or multilocular radiolucency with a cortical boundary. Despite no unique or pathognomonic clinical or radiographic features, the lesion shows potentially aggressive behavior. A 76-year-old male was referred to Gangneung-Wonju National University Dental Hospital with a chief complaint of slight swelling of the right mandible. Cone-beam computed tomography examination revealed a unilocular radiolucent lesion involving impacted third molar at the right posterior mandible. Slight lingual cortical thinning with suspected perforation was also shown. Histopathologically, multiple areas of cyst epithelium showed a glandular differentiation, resulting in mucoid-filled secretory cells and microcyst. Based on these findings, the final diagnosis was determined to be GOC.

In 1942 Stafne reported 35 asymptomatic, radiolucent cavities that were unilaterally located in the posterior region of the mandible between the mandibular angle and the third molar, and below the mandibular canal. The term Stafne bone cavity (SBC) is now used for such asymptomatic lingual bone depressions of the lower jaw. Since then there have been many reports of SBCs but very fews tudies have used cone-beam computed tomography (CBCT) for their diagnosis. The aim of this paper is to describe the clinical and radiological characteristics of two cases of SBCs and the importance of limited CBCT in confirming the diagnosis.

A 46-year-old man was referred to our hospital for treatment, complaining of swelling on the right mandibular molar region. Radiographic examination revealed a well defined multilocular radiolucent lesion with root resorption of right lower anteriors and molars. Following biopsy, a diagnosis of unicystic ameloblastoma of mural type was made and hemimandibulectomy was performed under general anesthesia. Histopathological examination of the surgical specimen exhibited a unicystic ameloblastoma of luminal, intraluminal, and mural type. Intraluminal proliferation was of plexiform pattern and mural proliferation showed unusual histopathological findings, which revealed follicular, acanthomatous areas coexisted with desmoplastic areas. This mural picture was similar to the so-called 'hybrid lesion of ameloblastoma', whose biological profile is not elicited due to the lack of adequate published reports. Two years follow up till date has not revealed any signs of recurrence.

Autotransplantation is the transplantation of embeded, impacted, or unerupted tooth, into extraction socket or surgically prepared socket in the same individual. Clinically, successful autotransplantation must show radiolucent space(periodontal ligament space) between transplanted tooth and supporting bone, lamina dura, no root resorption, no ankylosis, no inflammatory change, and physiologic tooth mobility. It is important that procedure is atraumatic, and the instruments should not contact the root surface during procedure. We performed autotransplantation of impacted mandibular canine that transversely located beneath the apices of the mandibular incisors with uncompletely developed apex. In radiographs and clinical evaluation, this transplant showed successful clinical finding except irregularity of mesial root surface after 14 months. It is conclued that transplantation of canine with $\frac{1}{2}{\sim}\frac{3}{4}$ root development provides a good chance of pulp survival, limited risk of root resorption and ensures sufficient final length, and is thus recommended.

The benign cementoblastoma is a benign odontogenic tumor of cemental-forming tissue, which has an unlimited growth potential. The radiographic appearance of the lesion is pathognomonic and consists of a radiopaque mass surrounded by a thin radiolucent line. This mass is inseparable, radiologically, from the tooth root and is attached to it. Microscopic evaluation suggests that the lesion enlarges by peripheral growth, with the center of the neoplasm being more calcified and inactive than the periphery. We have observed two cases of beneign cementoblastoma{mature calcified stage) occured in the left mandibular first molar of 22-year-old man and 14-year-old man.
