Leprosy is a chronic granulomatous disease caused by Mycobacterium leprae. The prevalence and number of new cases have recently markedly decreased in Korea, and the possibility of leprosy can therefore be clinically overlooked. However, leprosy is still endemic in various regions of the world. A 30 year-old male immigrant from Indonesia presented with an erythematous plaque without sensory loss on his face six months after immigration. The skin lesion was diagnosed as tuberculoid leprosy based on clinico-pathology.

Familial hypercholesterolemia is an autosomal dominant inherited metabolic disease characterized by high serum low-density lipoprotein (LDL) cholesterol concentrations, and xanthoma formation. There are multiple types of xanthomas, such as eruptive, tendinous, tuberous, and planar. Intertriginous xanthomas are rare, but, if present, are typically associated with familial homozygous hypercholesterolemia. We here report on a 15-month-old infant who presented with multiple yellowish linear patches and plaques on the intertriginous areas. Serum lipoprotein electrophoresis showed a marked increase in beta-fraction, suggesting type IIa hyperlipoproteinemia. Histopathology showed numerous aggregates of foam cells in the dermis. We performed DNA analysis and revealed the presence of an LDL receptor gene mutation. In summary, we here report an interesting case of an infant with intertriginous xanthoma. This condition is so rare that it has not been reported in the Korean dermatologic literature before.

BACKGROUND: The epithelial-mesenchymal transition (EMT) in epithelial tumor cells plays a key role in tumor invasion and metastasis. The reduction or loss of E-cadherin and the acquisition of vimentin are two critical steps in the EMT. However, the roles of EMT-related proteins in basal cell carcinomas (BCC) and squamous cell carcinomas (SCC) have not been fully elucidated. OBJECTIVE: The purpose of this study was to investigate the immunohistochemical expressions of E-cadherin and vimentin in BCC and SCC, and to demonstrate the EMT and its role in tumor invasion. METHODS: Paraffin-embedded tissues from 30 BCC and 20 SCC cases were incubated with primary antibodies to E-cadherin and vimentin. The co-expression of the biomarkers and the biomarkers' correlations with the histopathological grades were analyzed. RESULTS: E-cadherin expression reduced by 90.0% and 95.0% in BCC and SCC, respectively, and the expression of vimentin increased by 10.0% and 55.0% in BCC and SCC, respectively. The expression of vimentin was significantly different in BCC and SCC (p<0.05). There were no correlations between the expression of E-cadherin and the expression of vimentin in BCC (p>0.05), or between the expression of E-cadherin and the expression of vimentin in SCC (p>0.05). CONCLUSION: These results suggest that the EMT affects the pathophysiology of both BCC and SCC. The greater aberrance in the expression of vimentin in SCC compared with that in BCC might be one factor that underlies the greater aggression of SCC clinically.

The aim of this case study was to report the clinical outcome of immediate provisionalization using one-piece narrow diameter (3.0mm) implants in missing maxillary lateral or mandibular incisors. The present study included 36 patients who were treated with 62 one-piece narrow diameter implants. After implant placement, immediate provisional restorations were delivered. All implants showed favorable osseointegration and after progressive loading from 3 months to 9 months (average of 5 months), final restorations were completed without failure in all cases. A survival rate of 100 % (62 of 62) was observed up to 23 months of observation (average of 12.6 months).
