BACKGROUND: Epidermolysis bullosa simplex with muscular dystrophy (EBS-MD; OMIM #226670) is an autosomal recessive disease, characterized mainly by skin blistering at birth or shortly thereafter, progressive muscle weakness, and rarely by alopecia. EBS-MD is caused by mutations in the PLEC gene (OMIM *601282), which encodes plectin, a structural protein expressed in several tissues, including epithelia and muscle. We describe a patient affected with EBS-MD and diffuse alopecia in which we identified a novel pathogenic mutation by PCR amplification of all coding exons and exon-intron boundaries of PLEC gene, followed by bidirectional Sanger sequencing...

Primary Cicatricial Alopecias (PCAs) are a group of skin diseases in which there is progressive and permanent destruction of hair follicles followed by replacement with fibrous tissue. Unfortunately, by the time patients seek clinical evaluation of their hair loss, the skin is already inflamed and/or scarred, so there is little hope for a return to their normal hair growth pattern. Clinical and basic science investigations are now focusing on three forms of human PCA, lichen planopilaris (LPP), frontal fibrosing alopecia (FFA), and central centrifugal cicatricial alopecia (CCCA)...

Primary scarring alopecia (PSA) is caused by irreversible damage to the hair epithelial stem cells that reside in hair follicles. There is limited published work regarding PSA amongst the Asian population. The aim of this study was to evaluate the clinical features and to characterize the subtypes of PSA in southern Taiwan. In this retrospective case series, we reviewed 89 patients with pathology-confirmed PSA. The data was collected from National Cheng Kung University Hospital between 1988 through 2016. The clinical and histological data were reviewed, and the patients were characterized into different subtypes of PSA based on the clinical features and histological findings...

Importance: Current treatments for alopecia with autograft hair transplantation face limitations that may preclude complete hair restoration and leave patients with donor site scars. Scaffold assisted artificial hair implantation as demonstrated in a rat model may provide an adjunct for hair restoration without donor site morbidity. Objective: To design and create porous high-density polyethylene (PHDPE) and expanded polytetrafluoroethylene (ePTFE) hair-bearing scaffolds and evaluate their biocompatibility in a rat model...

Frontal fibrosing alopecia (FFA) describes the scarring, band-like recession of the frontotemporal hairline. Treatment is difficult, and currently, no evidence-based therapy exists. The purpose of this study is to report clinical features and treatment responses in a large cohort of patients with FFA. The authors analyzed a series of 72 patients with a clinical or histologic diagnosis of FFA. A total of 70 patients were female (97.2%), and 2 were male (2.8%). In females, the first onset of FFA was postmenopausal in 81...

Non-scarring hair loss is a common problem that affects both male and female patients. Since any disturbances in the hair follicle cycle may lead to hair shedding, or alopecia, it is not surprising that the possible role of vitamin D in alopecia was investigated in many studies. Vitamin D has been shown to have many important functions. A growing body of evidence shows that vitamin D and its receptor are responsible for maintaining not only calcium homeostasis but also skin homeostasis. Moreover, vitamin D could also regulate cutaneous innate and adaptive immunity...

Frontal fibrosing alopecia represents a peculiar condition with a quasi-symmetrical, marginal scarring alopecia along the frontal and temporal hairline. The condition has been associated with further histopathologic and/or clinical evidence of lichen planopilaris. Since its emergence with the original report of Kossard in 1994, frontal fibrosing alopecia has been recognized to be associated with a number of comorbidities, including lupus erythematosus. So far, respective case reports and case series have given account of frontal fibrosing alopecia with the histopathologic features of lichen planopilaris associated or overlapping with lupus erythematosus...

We describe 6 incomplete cases of frontal fibrosing alopecia (FFA). All patients were postmenopausal women. Their average age was 60 years; 2 of the women were Caucasian, and the remaining 4 women were of a mixed ethnicity. The disease duration ranged from 3 to 17 years. The patients' lesions presented as irregular alopecic plaques in the frontal and/or temporal regions, with few signs of perifollicular inflammation, slow progression, and progressive loss of the vellus hair in the frontal area. Loss of the eyebrows, facial hyperpigmentation, and loss of the body hair were observed in 3 patients, 1 patient, and 2 patients, respectively...

Scalp morphea presents as a scarring alopecia in en coup du sabre pattern. We report an unusual presentation of a round hairless patch of morphea on the occipital scalp present for 15 years. The scalp lesion aligned with 2 other hyperpigmented lesions of biopsy-proven morphea in the lower back. Pathology of horizontal sections from the scalp lesion showed follicular dropout, thickening of the collagen bundles, and preserved eccrine and follicular structures. Marked lymphocytic perineural infiltrate, a reported clue to the diagnosis of scalp morphea, contributed to the diagnosis...

NISCH syndrome is a rare autosomal recessive disease. It is characterized by scalp hypotrichosis, scarring alopecia, ichthyosis, and neonatal sclerosing cholangitis. It is caused by mutations in the CLDN1 gene encoding the claudin-1 protein, which is located at tight junctions. Fifteen cases have been reported to date and three different mutations have been identified. We report on the case of a 2-year-old boy from a consanguineous Moroccan family, presenting with NISCH syndrome and carrying the so-called Moroccan homozygous mutation (c...

Dissecting cellulitis of the scalp (DC) is a chronic inflammatory condition of the scalp that ultimately leads to scarring alopecia. A healthy 19-year-old male presented with a solitary, soft, alopecic nodule that had appeared 1 year before. A color Doppler ultrasound examination showed a hypodermal anechoic fluid collection in the left parietotemporal region of the scalp, connected to the base of widened hair follicles, and presented inner echoes suggestive of debris, as well as several fragments of hair tracts...

Traction alopecia was first described in 1904 but is still a cause of scarring hair loss in young women worldwide. It is unique in being initially a reversible then an irreversible (scarring) form of alopecia. Linked to tightly-pulled hairstyles, it is seen across all races. The pattern of hair loss depends on the style creating it but most commonly affects the frontotemporal hairline. There are some new examination findings associated with traction alopecia, which are traction folliculitis, the fringe sign and hair casts (pseudonits) on dermatoscopy...

Alopecia areata (AA) is an autoimmune inflammatory disorder of hair, characterized by non-scarring hair loss. 308-nm Excimer lamp (EL) has been reported as one effective modality in the treatment of AA. Khellin is a furanochromone photosensitizer whose chemical structure is close to psoralens and has previously proven its efficacy in vitiligo in association with UVA. We evaluated the efficacy and safety of a combination of topical khellin and 308-nm EL in the treatment of a refractory ophiasic AA (OAA), of 1-year evolution, in a 5-year-old boy...

BACKGROUND: Scalp defects can be reconstructed either with skin graft, local flaps, free flaps, or tissue expansion. Tissue expanders have been proved to be fruitful in the pediatric population. Scalp expansion has proved to be useful in the reconstruction of posttraumatic and postburn alopecic defects. Selective nerve block can be added for attenuation of sympathetic stimulation and decrease surgical stress in cranial surgeries. In this study, a comparison was done between using selective nerve block and without selective nerve block in both stages of tissue expansion procedure...

The peroxisome proliferator-activated receptor-gamma (PPARγ) regulates multiple aspects of skin physiology, including sebocyte differentiation, keratinocyte proliferation, epithelial stem cell survival, adipocyte biology, and inflammatory skin responses. However, the effects of its global deletion, namely of non-redundant key functions of PPARγ signaling in mammalian skin, are yet unknown, due to embryonic lethality. Herein, we describe the skin and hair phenotype of a whole body PPARγ-null mouse (Pparg(Δ/Δ)), obtained by preserving PPARγ expression in the placenta...

Central centrifugal cicatricial alopecia (CCCA) is a common and progressive form of lymphocyte predominant scarring alopecia which impacts negatively on the quality of life of those affected. It is seen more commonly in women of African descent with prevalence ranging from 2.7% to 5.7%. Current postulates include genetic inheritance, with traction inducing hairstyling practices and hair chemicals as aggravating factors. Histology reveals a perifollicular lymphocytic inflammation of the lower infundibulum, premature desquamation of the inner root sheath, and fibrous connective tissue...
