A case of cutaneous graft versus host disease (GvHD) presenting as fibrosing alopecia in a pattern distribution (FAPD) is discussed, possibly providing a mechanistic model for a better understanding of the pathogenic events underlying cicatricial pattern hair loss. The implication of a follicular inflammation and fibrosis associated with patterned hair loss has emerged from several independent studies. Eventually, Zinkernagel and Trüeb reported a peculiar type of cicatricial pattern hair loss with histopathological features consistent with lichen planopilaris (LPP) associated with androgenetic alopecia (AGA)...

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...

PURPOSE: Lichen planopilaris (LPP) is a chronic lymphocytic- mediated disorder that selectively involves hair follicles, leading to cicatricial alopecia. The eyelash follicle and meibomian gland (MG) might also be involved in the disease process leading to ocular surface problems. METHODS: In this Cross-sectional case -control study, twenty-three patients with histologically confirmed LPP and 23 healthy controls were recruited in this controlled study. To quantify the signs and symptoms of LPP, we used the Lichen Planopilaris Activity Index...

Lupus erythemathosus is a chronic, relapsing disease with acute, subacute, and chronic lesions. Effluvium telogen occurs in the setting of systemic activity of the disease, and cicatricial alopecia results from discoid lesionsin on the scalp. Other types of alopecia, like alopecia areata, may rarely be found in lupus. Frontal fibrosing alopecia is characterized by frontotemporal hairline recession and eybrow loss. Histophatologically, it cannot be differentiated from lichen planopilaris.It is controversial whether frontal fibrosing alopecia is a subtype of lichen planopilaris...

BACKGROUND: Lichen planopilaris (LPP) is a rare inflammatory lymphocyte-mediated disease of the scalp considered to have an autoimmune pathogenesis. OBJECTIVES: To identify the prevalence of medical comorbidities in patients with classic LPP (CLPP) and frontal fibrosing alopecia (FFA). METHODS: The medical records of 206 LPP patients and 323 control patients were retrospectively reviewed for existing comorbidities. The control group consisted of 257 patients with androgenetic alopecia (ICD 9 = 704...

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...

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...

Several treatment strategies have been proposed in classic lichen planopilaris (LPP), although no gold standard therapeutic approach has been recognized so far due to the variable and, sometimes, contradictory results reported in the literature, as well as due to the lack of guidelines and randomized controlled trials. In the present review, we sought to provide an updated overview on the treatment of classic LPP by analyzing the level of evidence of published studies, also proposing a possible therapeutic strategy according to the findings highlighted in this systematic review...

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...

BACKGROUND: Lichen planopilaris (LPP) and frontal fibrosing alopecia (FFA) represent 2 entities that cause primary cicatricial alopecia. These entities are clinically different; nevertheless, the literature suggests that FFA represents a form of LPP. The main argument in support of this hypothesis is that previous studies comparing the histologic findings have not found obvious differences between these diseases. METHODS: Our objective was to more critically compare and contrast 20 histologic findings of these diseases in a large number of patients in order to determine any significant histologic differences between LPP and FFA...

Postmenopausal lichen planopilaris (PLPP), also known as fibrosing frontotemporal alopecia Kossard (FFAK), is a not uncommon inflammatory scalp disease affecting approximately 5% of patients at specialized hair centers. The overall incidence of sporadic occurrence is believed to be just under 1% in the older, predominantly female, general population. Since the disease is often undiagnosed, it is statistically likely to be underrepresented. It especially occurs in postmenopausal women who are in the 6th and 7th decade of life (90%), but also in about 10% of premenopausal women, and in men it is documented only in isolated cases...

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...

BACKGROUND/OBJECTIVES: Lichen planopilaris is a primary lymphocytic cicatricial alopecia. Management of patients with lichen planopilaris is difficult due to a paucity of high-quality data on its epidemiology and pathogenesis and the efficacy of therapies. The purpose of this study was to report the characteristics and treatment outcomes of patients with lichen planopilaris in a tertiary referral centre. METHODS: A retrospective review of medical records in patients with lichen planopilaris seen in the Hair Clinic at the Skin & Cancer Foundation Inc...
