Telogen effluvium is one of the most common forms of non-scarring alopecia for which patients present to a dermatologist. It is a challenging disorder to treat and study, primarily owing to its multifactorial etiology which includes both physiologic and non-physiologic factors. Nutritional deficiency has been purported to contribute to hair shedding, and a patient's clinical history usually aids in directing laboratory evaluation. Many prior studies have either supported or failed to find a correlation between telogen effluvium and deficiencies in vitamins and minerals, in particular, vitamin D, ferritin, vitamin B12, folate, and zinc...

Alopecia areata (AA) affects anagen hair follicles, resulting in non-scarring hair loss. Since introduced by Huang et al., superficial cryotherapy has been accepted as a considerable primary therapeutic modality for AA. The aim of this study was to objectively clarify the therapeutic efficacy and safety of superficial hypothermic cryotherapy for treatment of AA. Medical records of 353 patients from 1993 to 2014 were retrospectively analyzed. According to the response to the superficial cryotherapy, patients were categorized into four groups: "marked", "partial", "poor" and "no recovery"...

Alopecia in a linear pattern is very rare with only a few cases reported in the medical literature. We report a case of linear non scarring alopecia involving the scalp in a 17-year-old boy with a histological diagnosis of lupus panniculitis. We report this case because of its rarity and also the inclusion of this entity as one of the rare differential of non scarring alopecia.

The diagnosis of primary scalp alopecia remains one of the most challenging fields in dermatopathology. In this review, we would like to connect the established classification of primary alopecia into scarring (cicatricial) and non-scarring (non-cicatricial) with current concepts. We introduce a simplified pathway for the diagnosis of the most common causes of alopecia, including a discussion of tissue processing techniques and use of immunohistochemistry.

Alopecia areata (AA) is a common hair loss disorder characterized by discrete, well demarcated areas of non-scarring terminal hair alopecia, with the calculated lifetime risk of ~2%. In past decades, linkage and GWA studies have implicated dozens of susceptibility genes/loci that are linked to the development of AA. Fischer et al performed a genome-wide CNV analysis of 585 AA patients and 1,340 controls in a European population. This is the first genome-wide study of CNV to be performed in AA samples, and the association finding in the MCHR2 gene region further underscores the potential role of pigmentation in AA development...

BACKGROUND: Eccrine duct dilation (EDD) and syringoma-like sweat duct proliferation have been described as reactive changes occurring in a variety of skin conditions. However, extensive evaluation of EDD in scalp biopsies performed for alopecia has not been performed. METHODS: We retrospectively examined 129 cases of cicatricial alopecia (lichen planopilaris, central centrifugal cicatricial alopecia, and discoid lupus erythematosus) and 130 cases of noncicatricial alopecias (androgenetic alopecia, telogen effluvium, and alopecia areata) for the presence of EDD...

BACKGROUND: Lichen planopilaris (LPP) is a follicular variant of lichen planus. A new subtype of LPP mimicking androgenetic alopecia (AGA) may be misdiagnosed. Inappropriate medical therapy or hair transplantation may exacerbate this subtype. OBJECTIVE: To introduce clinicopathologic findings of a new subtype of LPP that selectively affects vellus hair in the pattern of AGA. MATERIALS AND METHODS: In a cross-sectional study, 433 (66.6%) men and 217 (33...

INTRODUCTION: Alopecia can have a significant negative impact on patient's lives. The objective of this study is to describe some of the emotional and psychological challenges that affect women with scarring alopecia. METHODS: A qualitative study design was used with open-ended, individual interviews with 10 women with biopsy-proven scarring alopecia. Interviews were audio-taped, transcribed verbatim and analyzed thematically using ATLAS.ti analysis software. RESULTS: Four overarching major themes (with several subthemes) emerged including: the negative emotional impact of scarring alopecia, difficulties with concealing hair loss, negative experiences with diagnosis/management and the importance of support from others...

Erosive pustular dermatitis of the scalp (EPDS) typically affects elderly people with scarring alopecia. Videodermoscopy (VD) of the scalp has never been assessed in the diagnosis of EPDS. To evaluate the trichoscopy features of EPDS, we carried out a retrospective analysis of VD images obtained in the scalp of ten patients who affected by EPDS and were compared with those obtained from a series of thirty patients who affected by other type of scarring alopecia. The most specific VD feature was thus represented by evident hair bulb in the scarring scalp, observed in all patients...

Studies of proliferative hemangiomas have led to the discovery that interactions of endothelial cells with extracellular matrix and/or Vascular Endothelial Growth Factor (VEGF)-A stimulate the expression of VEGFR1, the VEGF decoy receptor, and suppress VEGF-dependent VEGFR2 signalling by a mechanism that requires the matrix-binding receptor Anthrax Toxin Receptor (ANTXR)1, VEGFR2, β1 integrin and the Nuclear Factor of Activated T cells (NFAT). In hemangioma endothelial cells, all these components are present, but are functionally compromised, so that the levels of VEGFR1 are extremely low and VEGFR2 signalling is constitutively active...

BACKGROUND: Split skin grafting (SSG) is the cornerstone in the treatment of deep burns and large skin defects. Frequently used donor sites are the thigh, abdomen and buttocks. The scalp is less common while considered as a reliable donor site. Advantages are a large surface area, rapid wound healing, cosmetically favourable results and multiple harvests from the same donor site. Complications include scab formation, chronic folliculitis and alopecia but have been recorded sporadically in previous studies...

Central centrifugal cicatricial alopecia (CCCA) is the most common scarring alopecia among African American women. Data about epidemiology, etiology, genetic inheritance, and management are scarce and come from individual reports or small series. CCCA has been associated with hot combing and traumatic hair styling for years; however, studies fail to confirm it as the sole etiologic factor. It has been shown in a small series that CCCA can be inherited in an autosomal dominant fashion, with a partial penetrance and a strong modifying effect of hairstyling and sex...

Microneedling is a very simple, safe, effective, and minimally invasive therapeutic technique. It was initially introduced for skin rejuvenation, however, now it is being used for a very wide range of indications including acne scar, acne, post-traumatic/burn scar, alopecia, skin rejuvenation, drug delivery, hyperhidrosis, stretch marks, and many more. Moreover, during the last 10 years, many new innovations have been made to the initial instrument, which was used for microneedling. This technique can be combined with other surgical techniques to provide better results...

Androgenetic alopecia (AGA) is characterized by a non-scarring progressive miniaturization of the hair follicle in predisposed men and women with a pattern distribution. Although AGA is a very prevalent condition, approved therapeutic options are limited. This article discusses the current treatment alternatives including their efficacy, safety profile, and quality of evidence. Finasteride and minoxidil for male androgenetic alopecia and minoxidil for female androgenetic alopecia still are the therapeutic options with the highest level evidence...

A 33-year-old female with a 7-year history of CD8-positive hypopigmented mycosis fungoides (MF) involving the trunk and extremities presented with a large well-defined alopecic patch on her frontal scalp. Clinically, this area resembled alopecia areata (AA) and was without hypopigmentation or erythema. A scalp biopsy revealed a non-scarring inflammatory alopecia and a superficial band-like atypical lymphoid infiltrate with prominent epidermotropism. Atypical, predominately CD8-positive lymphocytes were seen surrounding and infiltrating the bulb portion of several hair follicles...

BACKGROUND: Aesthetic micro-needling (MN) has demonstrated skin permeability to cosmeceutical ingredients and platelet-rich plasma by creating reversible micro-channels in the skin. OBJECTIVES: The purposes of this study were to determine: (1) actual needle depth-penetrations by adjusting needle lengths in a disposable tip of an electric MN device; (2) time-dependent passage of pigment and platelets; and (3) safety and efficacy profiles in patients. METHODS: Excised micro-needled pre-auricular skin was used to determine actual depths of tissue penetration with six needle lengths, and the presence of massaged pigment particles (histological examination) and fluorescein-labeled platelets (confocal laser microscopy) in 1 mm depth micro-channels over an hour...

Alopecia areata (AA) is one of the most common causes of non-scarring hair loss, which is associated with the premature induction of hair follicle regression. The pathogenesis of AA is unknown, although it is believed that a complicated autoimmune mechanism with Th1 lymphocytes and proinfammatory cytokines, such as IFN-γ, TNF-α, IL-1 and IL-2, may be involved. AA may occur as a single disease entity or coexist with other autoimmunological disorders. In some cases the relationship with infammatory bowel disease (IBD) was observed and the link between molecular pathways and main proinfammatory cytokines in IBD and AA has been suggested...
