특발성 치근외흡수의 처치: 증례 보고

저자 최유리나, 김현하, 박수정

초록

External root resorption is one of the rare pathological condition of tooth. It is occurred when periodontal ligament or cementum on the root surface are either damaged or denuded. The causes and classifications have been variously described. Because of the various causes and patterns, and absence of sufficient and consistent evidence for treatment, proper diagnosis and treatment plan based on clinician’s experience and close communication with patient is important. This case report represents the rare case of external root resorption and the treatment. The tooth was retained functionally in oral cavity showing good healing state in 2-year follow-up.

복잡치아종을 보이는 석회화낭종성 치성종양 증례- 유령세포에서 베타-카테닌, GADD45, 및 LC3의 면역조직화학적 과발현 -

저자 이상신, 김연숙, 이석근

초록

A nineteen years old male patient showed a cystic lesion in left maxillary canine to premolar area (#23-#25). This lesion was asymptomatic, and found during his routine radiological check in local clinic. In the radiological observation the cystic lesion showed round radiolucent image containing many calcified bodies which were usually small but irregular in shape, expanding tumorously and resulted in the displacement of canine and second premolar in the absence of first premolar. The lesion was surgically enucleated, and a cystic fibrous tissue containing abnormal teeth was removed and examined pathologically. With the histological observation of tumorous odontogenic epithelium including many ghost cells, which were closely associated with abortive teeth, the lesion was finally diagnosed as CCOT associated with complex odontoma. The ghost cells of CCOT was strongly positive for β-catenin, GADD45, and LC3, and slightly positive for MMP-9, while they were rarely positive for BCL2, Wnt1, HSP-70, and p38. Therefore, it was presumed that the ghost cells of CCOT might undergo dormant cell state through altered cytodifferentiation stimulated by severe growth arrest, DNA damage signaling, and abundant autophage formation.

구개부에 발생한 구강 섬유림프종- 증례보고-

저자 박정원, 정태영, 박상준

초록

Oral Fibrolipoma on Palate: A case report Jung-Won Park, Tea-Young Jung, Sang-Jun Park Department of Oral and Maxillofacial Surgery, Inje University Busan Paik Hospital, Busan, Korea Fibrolipoma, a variant of lipoma, is rare in oral cavity, and the pathogenesis is uncertain. The diagnosis and differentiation of fibrolipoma with other clinically similar lesions is very essential for proper treatment planning. We present a case of fibrolipoma on palate of a 28-year-old male.

혀에 발생한 선천 흑색증성 모반-증례보고-

저자 김강혁, 조정우, 정승환, 김진수, 박재억, 김창현

초록

Oral hyperpigmentation is common in patients older 40 years. But lesions in a newborn are unusual and congenital melanotic macule of the tongue has rarely been reported. A 2-month-old infant with 3 pigmented lesion on the right side of the dorsal tongue was evaluated. They were brown black but not homogeneous in color, smooth, nonblanchable, and nonpalpable, with irregular margins. We recommend excisional biopsy under general anesthesia because of possibility of malignancy, but parents refuse invasive procedure. On a following-up examination of the child at the age of 1 year, the pigmented lesions were unchanged. We report a case of congenital melanotic macules on the tongue and a review of literature about the lesion.

점액표피양암종세포주에서 Bax 활성화 유도를 통한 Cisplatin의 항암효능

저자 유현주, 조남표, 정요셉, 신지애

초록

Cisplatin is a well-known platinum-containing anti-cancer drug against bladder, ovarian, lung and testicular cancer. However, the potential effects and molecular targets of cisplatin in human mucoepidermoid carcinoma (MEC) are not fully understood. Here, we investigated the apoptotic effect and underlying mechanism of cisplatin in human MEC cells. The potential effects of cisplatin were evaluated by trypan blue exclusion assay, Western blotting, 4’-6-diamidino-2-phenylindole (DAPI) staining, live/dead assay and immunocytochemistry. Cisplatin suppressed cell growth and enhanced expression of cleaved PAPR in MC3 and YD15 cells. Cisplatin caused morphological change of nuclei and increased the number of ethidium homodimer-1-stained cells. In addition, cisplatin commonly increased Bax activation in both cells, while other Bcl-2 family proteins were not affected. These results suggest that cisplatin might induce apoptosis by activating Bax protein, which would provide baseline data for development of effective treatment strategy against MEC.
