Alopecia is one of the clinical manifestations of secondary syphilis. It is uncommon for hair loss to be the sole or predominant manifestation, as hair loss is the chief clinical and histologic differential diagnosis of alopecia areata. The main difference between these two entities is the detection of Treponema pallidum in syphilis. We present the case of a 24-year-old Hispanic man, human immu...

Surgical correction of cicatricial alopecia can yield exceptional results when performed in the appropriate clinical scenario. To facilitate determination of the most suitable corrective therapy, we propose two new categories of cicatricial alopecia: "unstable" and "stable." Unstable cicatricial alopecia is intermittent and results in possible subsequent scarring hair loss in either new or old ...

Numerous cutaneous side effects of combination Pegylated interferon alfa-2b (PEG-IFN) and ribavirin (RBV) therapy have been reported. Although cases alopecia areata (AA) associated with PEG-IFN/RBV therapy have been reported in the literature, but alopecia universalis is uncommon entity. We have treated up till now around 3500 patients suffering from this disease with Pegylated Interferon-2b an...

Alopecia areata is among the most prevalent autoimmune diseases, yet compared with other autoimmune conditions, it is not well studied. This in part results from limitations in the C3H/HeJ mouse and DEBR rat model systems most commonly used to study the disease, which display a low frequency and late onset. We describe a novel high-incidence model for spontaneous alopecia areata. The 1MOG244 T ...

Background: Chemotherapy-induced alopecia (CIA) is a common side effect of cancer treatment with profound psychosocial repercussions. Several young (before day 14) and adult (after 3 weeks) murine models for CIA have been developed, yet no study thus far has compared these models. Young models are naturally synchronized in anagen while adult models require synchronization into anagen. Here, we ...

BACKGROUND Scalp dermoscopy plays an important role in the diagnosis of hair and scalp disorders, and specific dermoscopic patterns have recently been associated with several disorders causing noncicatricial alopecia, such as androgenetic alopecia, alopecia areata, trichotillomania, and tinea capitis. OBSERVATIONS We describe the morphologic and pathologic features of a new dermoscopic patter...

The androgen receptor (AR) gene encodes a transcription factor, which mediates androgen action in target tissues, including the prostate. Prostate cancer is androgen dependent, implicating AR in susceptibility to this male condition. Male pattern balding, androgenetic alopecia, has recently been associated with prostate cancer, suggesting shared androgen pathways. The CAG and GGC repeats in the...

The relationship between psychological factors and alopecia areata is already a controversial issue. Previous researches have mainly focussed on the impact of stressors and occasionally the underlying psychiatric disorders. The relationship of personality with this disease has not been investigated. A group of alopecia areata patients ( n=31) was compared with a control group ( n=31) of age mat...

AIM To determine the frequency and the characteristics of cutaneous manifestations, especially vitiligo and alopecia areata, in patients with chronic graft-vs-host disease (cGVHD). METHODS 50 patients with cGVHD were prospectively enrolled in the observational study protocol and evaluated by an experienced dermatologist. The evaluation was focused on the clinical spectrum of skin and adnexal ...

BACKGROUND Alopecia areata is an immune mediated inflammatory hair loss, which occurs in all ethnic and age groups, and both sexes. However no significant etiology has been known for this disease. Helicobacter pylori (H. pylori) , is an organism colonized in gastric mucosa. This bacterium has been associated with certain extra-digestive dermatological conditions. The causal relationship between...
