        Cemento-ossifying fibroma (COF) is classified as a fibro-osseous lesion and usually presents as a progressively growing lesion that can reach a large size if left untreated. Fibrous dysplasia (FD) is a non-neoplastic development that affects the craniofacial bones and is characterized by painless hypertrophy due to the replacement of bone by abnormal fibrous tissue. Herein, a case of concurrent occurrence of COF and FD involving the right mandible is described in a 14-year-old male patient. In this review, the current knowledge of FD and COF is summarized, emphasizing the importance of integrating the understanding of clinical, radiographic, and histopathological features. In addition, the relevant aspects associated with differential diagnosis and patient care are evaluated.

        Lymphoma, which accounts for 3.5% of all oral cancers, is further divided into Hodgkin's lymphoma (HL) and non-Hodgkin's lymphoma (NHL). NHL accounts for 96% of lymphomas, and diffuse large B-cell lymphoma (DLBCL) is the most common subtype accounting for 32% of NHL. In the oral cavity, extra-nodal non-Hodgkin's lymphoma may develop in the dentoalveolar region of the maxilla or mandible. It can also mimic inflammatory lesions that occur around periodontal tissues, such as periapical granuloma and chronic osteomyelitis. Misdiagnosis of jaw lymphoma can delay appropriate treatments and worsen the prognosis. Therefore, to avoid delay in diagnosis, clinicians should identify the possible malignancy based on unusual symptoms, clinical findings, radiographic examinations, and histopathological evaluation. We present two cases of DLBCL in the right posterior mandible of a 64-year-old man who was initially misdiagnosed as acute apical abscess and in the right posterior maxilla of an 81-year-old woman who was initially misdiagnosed as chronic periodontitis. These cases demonstrate that it is important for both pathologists and clinicians to consider malignant lesions such as lymphomas in the differential diagnosis of apical radiolucency.

        Intraosseous vascular malformation, a representative vascular disease, rarely occurs in the oral and maxillofacial region, especially the maxilla. An 18-year-old female patient was referred to our department with the chief complaint of a radio-opaque mass in the maxilla. A biopsy was attempted at a local dental hospital before visiting our hospital, but it was not completed due to severe intraoperative bleeding. The patient presented swelling and induration in the right maxillary region without pain, local heat, or fluctuation. According to radiographic and clinical examinations, intraosseous vascular malformation or a bone-forming tumor such as aggressive osteoblastoma was suspected. Therefore, an open biopsy of the lesion was performed under general anesthesia. Histopathological examination revealed that the lesion consisted of bony trabeculae with fibrous connective tissue and numerous vascular structures, and the lesion was diagnosed as intraosseous vascular malformation.

        Differential diagnosis of the malignant lesion and the benign lesion is critically important for the precise treatment. A clinician should diagnose in a comprehensive manner considering clinical, radiological, and histopathological perspectives. The lesion in the oral cavity in this study was clinically and radiologically malignant. However, the lesion was histopathologically benign. Surgical intervention was not performed except biopsy. The lesion improved after about one month of supportive medication after the biopsy. The importance of decision making process was emphasized in this report.

        The most common benign salivary gland tumor is pleomorphic adenoma. It affects major and minor salivary glands. Minor salivary gland tumors constitute <20% of all salivary gland neoplasms. Most minor salivary gland tumors occur on the palate. We present the case of a patient with pleomorphic adenoma that developed at a rare intraoral location. This patient presented to the Department of Oral and Maxillofacial Surgery of Seoul National University Dental Hospital.

        Florid cemento-osseous dysplasia (FCOD) is benign and exhibits multifocal involvement of tooth-bearing areas of the jaw. Initially, the lesions are radiolucent but become mixed. In late stages, the lesions change into a radiopaque mass with a thin radiolucent rim. Most FCOD cases are asymptomatic, and conservative treatment is recommended. However, surgical intervention is necessary in secondary infected cases. Because of hypovascularity, infected lesions are difficult to manage and do not respond to antibiotic medications. This clinical report describes the treatment of secondary infection of an FCOD lesion with both conservative and surgical interventions.

        Extramedullary plasmacytomas (EMPs) are rare soft tissue malignant neoplasms composed of plasma cells. They are sometimes found in soft tissues. The majority of primary EMPs occur in the head and neck region, especially in the upper respiratory tract and oral cavity. We present a case of a 52-year-old female with an EMP. The patient’s initial chief complaint was swelling of the soft palate. An excisional biopsy was performed under general anesthesia. Final pathologic diagnosis was EMP of the soft palate with partial involvement of the resection margin. In order to exclude the possibility of multiple myeloma, a bone marrow exam with chromosomal study was completed. The patient was also referred to the Department of Radiation Oncology for postoperative radiation therapy (PORT); however, the patient refused to undergo PORT. The patient is currently under close observation for signs and symptoms of recurrence or metastases through regular follow-up visits and imaging studies.

        꽃게 조미소재, 야채, 천연조미료 등을 활용하면서, 편의 성을 부여하기 위하여 꽃게풍미 볶음밥을 제조하였다. 꽃 게풍미 볶음밥의 저장 중 품질변화를 조사하기 위해 –20, 4, 25℃에서 6주 동안 저장하면서 pH, 산도, 총균수, TBA, VBN, 관능적 기호도를 조사하였으며, 총균수 결과를 활용 하여 볶음밥의 유통 기한을 예측하였다. pH 변화를 조사한 결과, -20℃에 저장된 볶음밥의 경우 저장 0주째 pH는 7.74 이었고 저장 6주에는 pH 7.76으로 나타나 저장 중 변화가 거의 없는 것으로 나타났다. 적정산도를 조사한 결과, -20℃ 에 저장된 볶음밥의 경우 저장 0주째에 0.4%이었고 저장 6주에는 0.4%로 거의 변화가 없었다. 반면, 4℃ 와 25℃ 의 저장 6주에는 각각 2.7%, 4.6%의 수준으로 나타났다. TBA 값을 측정한 결과, -20℃에 저장한 볶음밥의 경우 저장 0주째 1.07 μg/g이었고, 저장 6주까지 1.39 μg/g으로 나타나 저장 중 다소 증가하는 경향을 보였다. 휘발성염기질소를 조사한 결과, -20℃에 저장된 볶음밥의 경우 저장 0주째에 26.60 mg%이었고, 저장 6주에는 28.14 mg%로 나타나 신선 도가 유지되는 것으로 사료되었다. 4℃와 25℃의 저장 6주 에는 각각 65.15 mg%, 68.00 mg% 수준으로 나타났다. 총균 수의 변화를 조사한 결과, -20℃ 저장된 볶음밥의 경우 저장 0주째 3.58 log CFU/g이었고 저장 6주째에는 4.11 log CFU/g으로 나타나 미생물변화는 안정적인 것으로 관찰되 었다. 관능적 기호도를 조사한 결과, -20℃에 저장된 볶음밥 의 경우 종합적 기호도의 변화를 보았을 때, 저장초기 7.8이 었고 6주째에는 6.7으로 나타나 저장 기간 동안 처리구 중 가장 높은 평가를 받았다. 25℃의 경우 저장초기 7.5이었으 나, 저장 6주째 1.0 수준의 평가를 받아 저장온도 및 저장기 간 동안 가장 낮은 평가를 받았다. 미생물 결과를 토대로 볶음밥의 유통기한을 예측한 결과, -20℃에 저장할 경우 14.9주, 4℃에서 저장할 경우 0.4주 인 것으로 각각 조사되었 다. 이상의 결과를 종합해 볼 때, 꽃게풍미 볶음밥은 -20℃에 서 저장하는 것이 미생물학적 및 관능적인 측면에서 저장성 이 좋을 것으로 사료되었고, 편의식품화로서의 이용 가능 성이 있을 것으로 생각되었다.
