Dermoscopic Changes of Melanocytic Nevi after Psoralen-Ultraviolet A and Narrow-Band Ultraviolet B Phototherapy.

Background: Phototherapy may alter the morphologic features of melanocytic nevi. Dermoscopy is a non-invasive method for evaluation of skin lesions, specifically melanocytic nevi.

Aims And Objectives: This study was designed to evaluate the effects of narrowband ultraviolet B (NB-UVB) and psoralen-ultraviolet A (PUVA) therapy on the dermoscopic features of nevi.

Human Papillomavirus Deoxyribonucleic Acid may not be Detected in Non-genital Benign Papillomatous Skin Lesions by Polymerase Chain Reaction.

Background: Papillomatosis is a known histopathologic pattern usually seen in human papillomavirus (HPV) infection and verruca vulgaris is the typical example. This pattern is also detected in some other benign cutaneous lesions such as nevus sebaceous (NS), seborrheic keratosis (SK), trichilemmoma (TL) and inverted follicular keratosis (IFK). The association between papillomatous lesions and HPV infection is questionable.

Association between HLA-DQB1*03:01 and Bullous pemphigoid in Iranian patients.

Background: A common Human Leukocyte Antigen (HLA) class II allele, DQβ1*03:01, seems to be associated with Bullous pemphigoid (BP) in Caucasians whereas previous studies in other ethnic groups showed other HLA class II alleles as genetic predisposing factors for BP.

Objective: To investigate the association of HLA class II alleles and haplotypes with BP in Iranian population.

Methods: Fifty patients with Bullous pemphigoid and 180 geographically matched, healthy individuals as control group enrolled into this study.

Pigmented purpura dermatosis and viral hepatitis: a case-control study.

Pigmented purpuric dermatosis (PPD) is characterized by petechial and pigmented macules on the lower limbs. The aetiology of PPD remains obscure. Some reports have suggested an association between PPD and hepatitis B or C infection.

Evaluation of the effect of disease duration in generalized vitiligo on its clinical response to narrowband ultraviolet B phototherapy.

Background/purpose: Narrowband ultraviolet B (NB-UVB) has been accepted as an effective therapy for generalized vitiligo. On the other hand, different factors seem to contribute to a good response. The purpose of this study is to evaluate the influence of disease duration on its clinical response to NB-UVB phototherapy.
