Introduction: Lichen planopilaris (LPP) is a lymphocytic primary cicatricial alopecia presenting with scarring hair loss and variable degrees of perifollicular erythema and scaling. Pustules are infrequent and may mimic folliculitis decalvans (FD) and other forms of neutrophilic alopecia. We present a series of LPP cases with pustules and discuss the importance of differentiating them from primary neutrophilic folliculitis. Materials and Methods: Demographic, clinical, histopathological, and follow-up data of 13 cases of LPP with pustules followed at the Department of Dermatology of the University of São Paulo Medical School were described...

BACKGROUND: Acne keloidalis nuchae (AKN) is a chronic inflammatory disease involving hair follicles of the neck. It is a form of keloidal scarring alopecia that is often refractory to medical or surgical management. OBJECTIVE: To evaluate the efficacy of Er:YAG laser in the treatment of AKN as compared to long pulsed Nd:YAG laser. PATIENTS AND METHODS: This study was conducted on 30 male patients with AKN. Their ages ranged from 19 to 47 years with a mean age of 36...

Sarcoidosis is a multisystem granulomatous disease most frequently affecting the lungs, lymph nodes, and eyes. Skin involvement occurs in approximately 25% to 35% of cases, with the scalp uncommonly affected. Abnormal calcium metabolism is associated with sarcoidosis and other granulomatous disorders and most commonly presents as hypercalciuria (40%-60%) and, less frequently, hypercalcemia (10%-20%). Symptomatic hypercalcemia is unusual, presenting in <5% of sarcoidosis patients, and rarely results in kidney damage...

BACKGROUND: Despite the growing popularity of platelet-rich plasma, existing evidence supporting its efficacy remains controversial due to the lack of large-scale studies and standardized protocols for preparation and application. This article reviews its use in facial rejuvenation, fat grafting, acne scarring, and androgenic alopecia. Emphasis is placed on comparing methods of platelet-rich plasma preparation and application across studies. METHODS: A systematic review was performed for articles published between 2006 and 2015...

Alopecia areata (AA) is an autoimmune non-scarring hair loss characterized by round patches on the scalp and body. It can progress to alopecia totalis (AT) where there is total loss of scalp hair and alopecia universalis (AU) in where hair loss encompasses the entire body. The pathophysiologic mechanism is unclear, but is thought to be due to peribulbar T-cell inflammation which results in premature induction of anagen follicles to catagen and telogen, without causing destruction of the hair follicle.

REVIEW
Victoria Billero, Mariya Miteva
Traction alopecia (TA) affects one-third of women of African descent who wear various forms of traumatic hairstyling for a prolonged period of time. The risk of TA is increased by the extent of pulling and duration of traction, as well as the use of chemical relaxation. The frequent use of tight buns or ponytails, the attachment of weaves or hair extensions, and tight braids (such as cornrows and dreadlocks) are believed to be the highest risk hairstyles. TA can also occur in the setting of religious and occupational traumatic hairstyling...

Inflammation-associated, irreversible damage to epithelial stem cells (eSCs) of the hair follicle in their immunologically privileged niche lies at the heart of scarring alopecia, which causes permanent difficult-to-treat hair loss. We propose that the two most common and closely related forms, lichen planopilaris (LPP) and frontal fibrosing alopecia (FFA), provide excellent model diseases for studying the biology and pathology of adult human eSCs in an easily accessible human mini-organ. Emphasising the critical roles for interferon (IFN)-γ and peroxisome proliferator-activated receptor (PPAR)-γ-mediated signalling in immune privilege (IP) collapse and epithelial-mesenchymal transition (EMT) of these eSCs respectively, we argue that these pathways deserve therapeutic targeting in the future management of LPP/FFA and other eSC diseases associated with IP collapse and EMT...

Central centrifugal cicatricial alopecia (CCCA) has an unknown mechanism. Analyzing other scarring diseases (lichen planopilaris, fibrotic kidney disease, and scleroderma) may help clarify the mechanism of scarring in CCCA. These diseases were chosen for comparison due to either their location of disease (skin or scalp specifically), or prominence in patients of African descent. Genetics, possible triggers, an autoimmune lymphocytic response, and epithelial to mesenchymal transition are potentially involved...

We present cases of localized alopecia on the vertex scalp of two girls after elaborate professional hairstyling marketed as the "Princess Package" at a major U.S. theme park. Localized alopecia followed pain, erythema, and delayed crusting due to necrosis of the scalp. The majority of the affected alopecic areas had evidence of regrowth at interval follow-up, but small areas of scarring alopecia remained. We propose that these cases represent a type of alopecia caused by a combination of pressure ischemia and acute traction alopecia...

In the classification of the North American Hair Research Society, primary cicatricial alopecias (PCA) are divided into four groups according to their prominent inflammatory infiltrate: PCAs with lymphocytic, neutrophilic, mixed or nonspecific cell inflammation pattern. The hair loss can begin subclinically and progress slowly so that the exact onset of the disease is often difficult to determine. The diagnosis is often delayed. While most forms of cicatricial alopecia can be clearly diagnosed based on clinical presentation in the acute disease stage, diagnosis can be challenging in the subacute, early or late disease stages...

BACKGROUND: We have reported that WNT10A plays a critical role in the growth of fibroblasts/myofibroblasts and microvascular endothelial cells, i.e.; wound healing/scarring. To ascertain the in vivo regulatory, central functions of WNT10A, we examined the net effects of WNT10A depletion using WNT10A-deficient mice (WNT10A-/-). METHODS AND RESULTS: We generated WNT10A-/-mice, displaying a range of unique phenotypes of morpho/organogenetic failure, such as growth retardation, alopecia, kyphosis and infertility, and then focused on the functions of WNT10A in wound healing...

Mechanical forces are known to regulate homeostasis of the skin and play a role in the pathogenesis of skin diseases. The epidermis consists of keratinocytes that are tightly adhered to each other by cell junctions. Defects in keratins or desmosomal/hemidesmosomal proteins lead to the attenuation of mechanical strength and formation of intraepidermal blisters in the case of epidermolysis bullosa simplex. The dermis is rich in extracellular matrix, especially collagen, and provides the majority of tensile force in the skin...

BACKGROUND: Hair bleaching is increasingly being carried out in hairdressing salons. The products used are a mixture of hydrogen peroxide and persulfates, both active chemical agents. Scalp burns secondary to hair bleaching are a traumatic adverse effect rarely discussed in publications that continue to be little known among healthcare professionals. PATIENTS AND METHODS: We report the case of a 15-year-old girl with a plaque of scarring alopecia on the vertex. This lesion resulted from a deep burn following a hair-bleaching procedure...

BACKGROUND: Since 2003 we have used the scalp as a donor site for split skin grafts (SSGs) in major burns when there was a shortage of conventional donor areas. However, we seen a high incidence of complications, contrary to international experience. OBJECTIVE: The aim of this study was to analyze the results and complications related to the scalp as a donor site and to determine whether there is an association between our specific patient population and the complications encountered...

Folliculitis decalvans (FD) is a chronic inflammatory disease leading to scarring alopecia with poorly defined pathogenesis. The aim of this study was to investigate the expression of markers associated with the activation of innate immune signals, such as inflammasome (NALP1 and NALP3), interleukin (IL)-1β and IL-8 and type I interferon (MxA). A retrospective monocentric study was conducted and included 17 patients with FD with available biopsies. Disease activity (stable vs. active) was defined clinically and histologically...

The microneedles technology has found applications in many health-related fields. For example, their application in drugs and vaccines delivery as well, as the determination of biomarkers, has been reported. They also have a place in the dermatology and cosmetic areas such as the treatment of wounds from burns, scars, acne, depigmentation, and alopecia will be shown. Microneedles are used in therapeutic applications and are manufactured using materials such as metal (steel, titanium, nickel), polymer (oly-glycolic acid (PGA), poly-lactide-co-glycolide acid (PLGA), poly-L-lactic acid (PLA), chitosan), glass, silicon, ceramic, carbohydrates (trehalose, sucrose, mannitol)...

Lichen planus is a T-cell mediated autoimmune disorder affecting the skin and mucous membranes. Ulcerating lichen planus is uncommon mostly on oral and genital mucosa but not skin. Lichen planopilaris, however, is a subtype of lichen planus affection hair follicles and leading to permanent scarring alopecia. We report a case of lichen planopilaris of the scalp with multiple alopecic patches ulceration - a hitherto unreported clinical feature. The patient was treated surgically, and the defect could be closed by combined tissue advancement and extension...

Alopecia Areata is a common form of non-scarring hair loss that usually starts abruptly with a very high psychological impact. Due to the still not completely understood etiopathogenesis, at present there is no treatment that can induce a permanent remission and there is no drug approved for the treatment of this disorder. Areas covered: Leading existing treatment are briefly overviewed and then ongoing research on Janus Kinases Inhibitors is discussed, reviewing trials with oral and topical formulations so as new opportunities for other forms of alopecia, such as cicatricial alopecia...
