BACKGROUND Tacrolimus (FK506) ointment has been used for treatment of inflammatory dermatoses with remarkable success. Our previous studies have indicated that direct modulation of tacrolimus on keratinocytes (KCs) may have an impact on its therapeutic effect. The use of monoclonal antibody specific for tumour necrosis factor (TNF)-alpha has shown efficacy(More)
BACKGROUND Vitiligo is an acquired pigmentary disorder characterized by depigmentation of skin and hair. As the pathogenesis of this disease is still obscure, the treatment of vitiligo has generally been unsatisfactory and often disappointing. Topical tacrolimus (FK506) ointment has recently been added to the armamentarium against this pigmentary disorder.(More)
BACKGROUND Patients with tuberous sclerosis complex (TSC) develop fibrous tumours in the brain, skin, kidney, heart and lungs due to TSC1/2 mutations. In the skin, patients develop angiofibromas that have vascular and fibrotic components in which transforming growth factor (TGF)-β and matrix metalloproteinase (MMP)-2 are important. OBJECTIVES To(More)
BACKGROUND Chemokines and their receptors, well known for their ability to attract leucocytes, also play important roles for tumour progression. OBJECTIVES To investigate the possible involvement of chemokine receptors in the pathogenesis of cutaneous basal cell carcinoma (BCC). METHODS We performed an expression analysis of chemokine receptors using a(More)
An 81-year-old woman came to our clinic (Department of Dermatology, Kaohsiung Medical University, Kaohsiung, Taiwan) with multiple erythematous, indurated papules over the left side of her face. Two years earlier, the patient had a skin biopsy done at a similar anatomical area with the histopathological diagnosis of Bowen's disease. After reviewing surgical(More)
BACKGROUND Behçet's disease (BD) is a recurrent multisystem disease of uncertain aetiology. The young adults are most often affected, usually during the third decade. Late occurrence of the disease is considered uncommon and less frequently investigated. OBJECTIVE The aim of this study was to examine the clinical features of BD patients with disease onset(More)
BACKGROUND Kaposi's sarcoma is a vascular tumour characterized by a proliferation of spindle cells and endothelial cells to form closely arranged slit-like vascular spaces. Currently, the definitive diagnosis of Kaposi's sarcoma relies on histology. The dermoscopic features of Kaposi's sarcoma are not clearly defined in the scientific literature. (More)
BACKGROUND We found previously that the features of Kaposi's sarcoma (KS) under polarized dermoscopy are characterized by a bluish-reddish coloration, a scaly surface, small brown globules and, most distinctively, the multicoloured 'rainbow pattern'. OBJECTIVES To evaluate the significance of the rainbow pattern on dermoscopy as a diagnostic feature in(More)
BACKGROUND Itch is the cardinal symptom of atopic dermatitis (AD). β-Endorphin, a neuropeptide, is increased in both AD skin and sera. Interleukin (IL)-31, an itch-relevant cytokine, activates IL-31 receptors in keratinocytes. However, how IL-31 and β-endorphin interact in AD skin remains elusive. OBJECTIVES To investigate the mechanistic interaction of(More)
