Certain types of alopecia, such as traction alopecia, discoid lupus erythematosus, and central centrifugal cicatricial alopecia, occur more commonly in African-American individuals than in those of other ethnicities. Both intrinsic hair qualities and hair care practices play a role. Lower baseline tensile strength, hair density, and growth rates, as well as the use of high-tension hairstyles and chemical relaxers may contribute to alopecia in this group. Alopecia can also occur as a result of discoid lupus erythematosus, which involves chronic lymphocytic infiltration and eventual scarring of the hair follicle...

BACKGROUND: Frontal fibrosing alopecia (FFA) is traditionally regarded as a variant of lichen planopilaris (LPP) based on histological features. Distinct clinical presentation, demographics and epidemiology suggest differing pathogenic factors determine the final phenotype. OBJECTIVES: To map the hair follicle immune system (HIS) in LPP and FFA by systematically comparing key inflammatory markers in defined hair follicle compartments. METHODS: Lesional scalp biopsies from LPP, FFA and healthy controls were stained with the following immunohistochemical markers: CD1a and CD209, CD4, CD8, CD56, CD68, CD123, CXCR3, FOXP3, mast cell tryptase and cKit...

Lichen planopilaris (LPP) is a cicatricial alopecia that often causes permanent hair loss. Pioglitazone, a peroxisome proliferator activated receptor-gamma (PPAR- γ) agonist, has demonstrated immunomodulatory properties that may offer an effective treatment modality. This retrospective analysis describes 23 patients with LPP treated with adjunctive pioglitazone. Most (18/25) demonstrated significant reduction in patient-reported symptoms and clinical signs of inflammation. No adverse effects were reported...

BACKGROUND: Folliculitis decalvans (FD) and lichen planopilaris (LPP) are classified as neutrophilic and lymphocytic cicatricial alopecias according to the North American Hair Research Society. Recently, a clinical phenotype combining concomitant or sequential features for both was described as a FD LPP phenotypic spectrum (FDLPPPS). OBJECTIVES: To review the most common phenotypic presentation of FDLPPPS with a main focus on histopathology. METHODS: We reviewed retrospectively series of 7 patients with a similar phenotypic presentation with special focus on the histologic pattern...

Background: We report a case of acute and severe lichen planopilaris (LPP)-like alopecia in a 35-year-old male construction worker following occupational exposure to trichloroethylene (TCE) and tetrachloroethylene (PCE). Case Report: Two weeks after initiating ground-intrusive construction at a previous dry-cleaning facility site, the patient developed sudden scalp pruritus and associated patchy hair loss. As subsequent scalp biopsies revealed LPP, he was started on hydroxychloroquine at 200 mg twice daily and clobetasol solution once daily...

Peroxisome proliferator-activated receptors (PPARs) are abundantly expressed in human skin, with PPAR-γ being the most intensively investigated isoform. In various ex vivo and in vivo models, PPAR-γ-mediated signalling has recently surfaced as an essential element of hair follicle (HF) development, growth and stem cell biology. Moreover, the availability of novel, topically applicable PPAR-γ modulators with a favourable toxicological profile has extended the range of potential applications in clinical dermatology...

BACKGROUND: Eccrine duct dilation (EDD) was recently described to occur more frequently in cicatricial alopecias than noncicatricial alopecias. Because single EDD can be useful in the evaluation of alopecias, we aimed to determine whether dilation of multiple eccrine duct units, or "multiple eccrine duct dilation (MEDD)," could more specifically discriminate between cicatricial and noncicatricial alopecias. METHODS: We retrospectively evaluated 611 scalp biopsies (342 cicatricial alopecias and 269 noncicatricial alopecias)...

Fibrosing alopecia in a pattern distribution (FAPD) is a relatively new entity in the family of cicatricial alopecia. It has been categorized as a member of the lichen planopilaris (LPP) group due to its similarity in clinical and histopathological presentation. Nonetheless, the disease earns its own entity due to its lichenoid inflammation exclusively involving miniaturized hair and area of involvement mimicking pattern hair loss which differentiates itself from other types of LPP or pattern hair loss. Since its first introduction by Zinkernagel and Trüeb in 2000, there have been only few case reports and series of FAPD...

BACKGROUND: Fibrosing Alopecia in a Pattern Distribution (FAPD) and Cicatricial Pattern Hair Loss (CPHL) are poorly recognized diffuse variants of Lichen Planopilaris (LPP). OBJECTIVES: The medical features of 40 patients affected by a diffuse hair thinning associated with a long-lasting history of pruritus and erythema of the scalp and a histopathological diagnosis of LPP were reviewed. METHODS: Clinical, trichoscopy, histopathology, response to treatment and follow-up were analyzed...

BACKGROUND: The purpose of the study was to compare the histopathologic and immunophenotypic features of central centrifugal cicatricial alopecia (CCCA) and lichen planopilaris (LPP) to better characterize and differentiate these two clinical entities. CCCA remains an ill-defined and still-unsettled histologic entity and many hair loss experts regard CCCA to be histologically indistinguishable from LPP. Given the overlapping histologic features of these two lymphocyte-predominant cicatricial alopecias, and the lack of consensus regarding the significance of proposed distinctions, dermatopathologists face difficulty in providing clinicians and patients certainty with a definitive diagnosis of CCCA vs LPP...
