Axillary osmidrosis (AO) and primary hyperhidrosis (PH) are common diseases, but there are still difficulties in treatment. Microwave therapy may become a new method. In order to evaluate long-time efficacy of patients with AO or PH treated by microwave and to discuss possible mechanism of microwave therapy by combining results of clinical and pathological, the study was carried out.

The familial occurrence of EMPD and the high risk of concomitant secondary tumors in EMPD patients have gained much attention. These findings highlight the importance of genetic alterations in the tumorigenesis of this skin cancer.
View Article and Find Full Text PDFExtramammary Paget's disease (EMPD) is a rare cutaneous malignancy accounting for approximately 1-2% of vulvar cancers. The rarity of this disease has caused difficulties in characterization and the molecular mechanism underlying EMPD development remains largely unclear. Here we used microarray analysis to identify differentially expressed genes in EMPD of the scrotum comparing with normal epithelium from healthy donors.

However, there is little evidence to demonstrate the presence of MTB in the skin lesions. This study is aimed at evaluating the association between MTB infection and the development of EN and NV in a Chinese population.

Therefore, we analyzed the possible mutations in the KRAS, HRAS, NRAS, BRAF, ARAF, RAF1, PIK3CA, AKT1, CTNNB1 and APC genes as well as methylation and expression of CDH1 in 144 EMPD cases and 42 matched normal skin tissues.

In this study, we investigated the expression levels, and mutation and methylation status of a common tumor suppressor gene, deleted in liver cancer 1 (DLC1), and an oncogene, PIK3CA, in tumor (n=132) and normal tissues (n=20) from unrelated patients.

View Article and Find Full Text PDFBackground: Nevus depigmentosus (ND) is frequently confused with vitiligo. Differential diagnosis can be difficult. In vivo reflectance confocal microscopy (RCM) is a noninvasive technique for real-time en face imaging of the superficial layers of the skin down to the superficial dermis with cellular level resolution close to conventional histopathology.
