혀 측면에 발생한 혈관내 유두모양 내피세포 증식증

저자 김병수, 은재승, 김봉철, 윤정훈

초록

Intravascular papillary endothelial hyperplasia (IPEH) is an unusual reactive benign lesion of vascular origin caused by endothelial cell proliferation, which rarely occurs in oral cavity. IPEH appears in various forms because it has non-specific clinical presentation, so it can be misdiagnosed as a malignant lesion.Therefore, it is important to make a differential diagnosis by understanding the characteristics of this lesion.We report a case of IPEH in a 22-year-old Korean female patient, discussing about differential diagnosis and treatment. This report presents review of literature and describes a case of IPEH. Key words : Intravascular papillary endothelial hyperplasia, Masson’s tumor, Tongue

초록

Lipoma is the most common soft tissue mesenchymal tumor which grows slowly. [1] [2] Intraoral lipomas are rare and have been reported in approximately 1 to 4% of all neoplasm in various literature. [2-5] Oral lipomas mostly develop slowly without symptoms, [6] and predominantly affect the buccal mucosa, floor of mouth, tongue and lip. [3] Material and Methods: A 71-year old male presented with asymptomatic swelling on tongue. On the clinical examination, there were various size of three swelling areas on the dorsum of tongue. Result: All lesions were surgically removed via intraoral approach under general anesthesia. They were soft and yellowish in color. All of the specimens has histologically revealed as typical lipomas. Conclusion: It is a report of tongue lipomas as a rare site, with clinical, histological and radiographic features. Also, there were several reports of a large or huge lipoma in oral cavity, however there were no report of multiple lipomas on the tongue. So, authors report the rarity of it.

초록

Pleomorphic adenoma (PA) is the most common benign salivary gland tumor. Being pleomorphic, its histologic characteristics can be considerably varied, showing epithelial (ductal and non-ductal) cells and mesenchyme-like tissues (chondroid, myxoid, and osseous). Here, we present a rare case of a 76-year-old female presenting with a 2.0 cm PA with an epidermoid cyst of minor salivary glands on the soft palate.

하악골에 발생된 골 내 평활근종: 증례보고

저자 김경아, 민창기, 고승오, 조남표

초록

The case of an intraosseous leiomyoma in a 22-year-old man is presented. The tumor was incidentally discovered during dental radiographic examination for endodontic treatment of mandibular first molar. Radiographic examination revealed a well-defined unilocular radiolucency between the roots of mandibular left canine-first premolar, measuring approximately 1.9 x 1.8 cm and perforation of the buccal cortical plate. Histological and immunohistochemical examination was diagnostic of intraosseous solid leiomyoma. Here, we report a rare case of leiomyoma of the mandible, together with conventional histopathologic and immunohistochemical findings.

초록

Calcifying Epithelial OdontogenicTumor(CEOT), also known as Pindborg tumor is a rare lesion comprising about 1% of all odontogenic tumors mostly rising in the posterior of the mandible. It generally occurs in patients between 30-60 years old. This paper describes a case of CEOT in a 17 year-old female affecting the right mandible. Histopathologic findings showed sheets of polygonal tumor cells and pools of amorphous, eosinophilic amyloids with calcifications. 1 year after resection of the tumor, no clinical and radiographic signs of recurrence were observed.

합성곱신경망의 학습 및 테스트자료에 따른 골다공증 판독에 미치는 영향

초록

This study aimed to test a convolutional neural network (CNN) in two different settings of training and testing data. Panoramic radiographs were selected from 1170 female dental patients (mean age 49.19 ± 21.91 yr). The cortical bone of the mandible inferior border was evaluated for osteoporosis or normal condition on the panoramic radiographs. Among them, 586 patients (mean age 27.46 ± 6.73 yr) had normal condition, and osteoporosis was interpreted on 584 patients (mean age 71.00 ± 7.64 yr). Among them, one data set of 569 normal patients (mean age 26.61 ± 4.60 yr) and 502 osteoporosis patients (mean age 72.37 ± 7.10 yr) was used for training CNN, and the other data set of 17 normal patients (mean age 55.94 ± 4.0 yr) and 82 osteoporosis patients (mean age 62.60 ± 5.00 yr) for testing CNN in the first experiment, while the latter was used for training CNN and the former for testing CNN in the second experiment. The error rate was 15.15% in the first experiment and 5.14% in the second experiment. This study suggests that age-matched training data make more accurate testing results.

상악동내에 발생한 석회화 동반 치성각화낭

초록

Odontogenic keratocyst (OKC), also known as keratocystic odontogenic tumor (KCOT), is an emerging odontogenic tumor originating from the dental lamina. It is an aggressive lesion with a squamous epithelium and a recurrence rate of 15-35%. Radiologically, there is a clear, smooth, or shell-like border showing a unilocular or multifocal, polycystic radiographic picture. Hard tissue formation in OKC is a very rare phenomenon and occurs in the form of dystrophic calcification, cartilaginous tissue or dentinoid. In this article, we report the case of OKC with calcification. OKC with radiopaque lesion is very rare, these are considered as dystrophic calcification, dentinoid formation, ossification. The incidence of dystrophic calcification in recurrent OKC is low, so it can be inferred that the recurrence rate of OKC with dystrophic calcification is lower than that of conventional OKC.
