Background: Folliculitis decalvans (FD) is a form of inflamed primary cicatricial alopecia (PCA). FD is classified as a neutrophilic PCA; however, only a few previous studies have described its histopathology, including the assessment of systematically evaluated and quantified follicular changes in horizontally sectioned biopsy specimens with clinical and dermoscopic findings of the early and advanced stages.

Objective: We aimed to clarify the histopathologic and dermoscopic features of early and advanced active stage FD. Read More

Introduction: Clinical diagnosis of primary cicatricial alopecias presents difficulties. Studies regarding their trichoscopic features are scarce and mostly not comprehensive. The aim of this study is to evaluate the potential benefit of a handheld dermatoscope in clinical diagnosis of primary cicatricial alopecias. Read More

Folliculitis decalvans is a rare clinical disorder classified as primary neutrophilic scarring alopecia with a slight preference for the male gender. Here, we report the use of autologous fat transplantation as a source of stem cell therapy for hair re-growth assisted by inflammatory action of the fat itself in a female patient. The patient underwent adipose transplantation in April and September 2017. Read More

An uncommon type of epidermal nevus characterized by hyperpigmented hyperkeratotic bands following a Blaschko-linear pattern and generalized follicular hyperkeratosis were observed in a 17-year-old male patient who additionally showed tufted hair folliculitis on the scalp and clinodactyly of the fifth finger of both hands. The combination of epidermal nevus with skeletal abnormalities was first described by Gobello et al. [Dermatology 2000;201:51-55] as a new epidermal nevus syndrome that was named after the first author of this work. Read More

Scarring alopecia or cicatricial alopecia results from follicular damage that is sufficient to cause the destruction and replacement of pilosebaceous structures by scar tissue. Primary scarring alopecias represent a group of disorders that primarily affect the hair follicles, as opposed to secondary scarring alopecias, which affect the dermis and secondarily cause follicular destruction. Inflammation may predominantly involve lymphocytes or neutrophils. Read More

Trichoscopy performed with a handheld dermoscope or a videodermoscope became an indispensable tool in differential diagnosis of hair and scalp diseases. Current research is focusing on trichoscopy of: 1) non-cicatricial alopecia, 2) cicatricial alopecia, 3) hair shaft disorders, and 4) inflammatory scalp diseases. This review summarizes current knowledge in these four fields of research. Read More

Pemphigus vulgaris is an autoimmune blistering disease that commonly involves the scalp. Lesions of pemphigus vulgaris that persist on the scalp for a long period may be accompanied by tufted hair folliculitis. Only two previous accounts of tufted hair folliculitis developing in a lesion of pemphigus vulgaris have been reported. Read More

Tufted hair folliculitis is a rare folliculitis of the scalp that resolves with patches of scarring alopecia within multiple hair tufts emerging from dilated follicular orifices. Tufting of hair is caused by clustering of adjacent follicular units due to a fibrosing process and to retention of telogen hairs within a dilated follicular orifice. Various pathogenetic mechanisms have been proposed including nevoid abnormalities, recurrent infections of the follicles, and retention of telogen hair in the tufts. Read More

A 25-year-old man presented with Touraine-Solente-Golé syndrome (primary pachydermoperiostosis), with an area of inflammatory dermatosis (12-month evolution) of the scalp at the cranial vertex. The patient presented with arthropathy, clubbing of the digits, diffuse periostosis, pachydermia of the hands and feet, and periosteal hyperostosis of the knee. Facial seborrhea and sebaceous gland hyperplasia were evident (Figure 1A and 1B and Figure 2A and 2B). Read More

Chemotherapeutic agents targeting the human epidermal receptor (HER) family are being used with increasing frequency for a variety of solid tumors. Cutaneous side effects are commonly reported with HER inhibitors, especially those agents that inhibit epidermal growth factor receptor (EGFR) or HER1. However, inhibitors of HER2 are not associated with specific skin toxicity. Read More

We report a case of tinea capitis mimicking tufted hair folliculitis in a 56-year-old European man, who presented with a 4-year history of pain and erythema in an area of scarring alopecia of the occipital scalp, with scales and tufts of hair emerging from individual follicles. Histological examination showed hair plugging, and a dense perifollicular infiltrate of plasma cells, lymphocytes, and neutrophils. There was widespread scarring and fibrosis. Read More

Keratosis follicularis spinulosa decalvans is a rare, X-linked disorder characterized by scarring alopecia of the scalp and eyebrows in the setting of widespread keratosis pilaris. Less frequent associations are ocular abnormalities and palmoplantar keratoderma. Acne keloidalis nuchae has previously been described in one patient with keratosis follicularis spinulosa decalvans.

Background: Primary cicatricial alopecias encompass a group of disorders characterized by permanent destruction of the hair follicle. The varied clinical features and differences in terminology have led to difficulties in defining consistent clinicopathologic correlation.

Objective: We sought clinicopathologic correlation of 6 clinically distinct primary cicatricial alopecias: lichen planopilaris, frontal fibrosing alopecia, pseudopelade (Brocq), central centrifugal alopecia, folliculitis decalvans, and tufted folliculitis. Read More

Background: A 47-year-old woman presented with erythematous lesions with papules and pustules on her parieto-occipital region that had been present for 8 months. Areas of sclero-atrophic alopecia were evident, whereas at different points tufted hair shafts were coming out from single dilatated follicular ostia. Before our observation, an antibiotic oral therapy with tetracyclines and local with erythromycin had been administered to the patient, with partial improvement and relapse on its suspension.

Tufted hair folliculitis (THF) is a rare disease which is characterized by the emergence of multiple hairs from widely dilated follicular orifices surrounded by an inflammatory infiltrate resulting in scarring alopecia. The pathogenesis is not yet fully understood. Although colonization with Staphylococcus aureus could not always be detected and systemic treatment with antibiotics alone is not sufficient, this microorganism is considered to play an important role.

A 35-year-old man developed red papules and plaques with alopecia and hair tufts on the parietal and occipital areas of his scalp. Each tuft was comprised of 5 to 25 hairs arising from individual hair follicules. Histopathological findings showed a dense infiltration of plasma cells in the dermis. Read More

We describe the case of a 38-year-old epileptic man with tufted hair folliculitis. The condition started 5 years ago after a scalp laceration that had been sustained 3 months earlier during an epileptic crisis. There then appeared a circumscribed inflammatory bulging lesion (with exudation and crusts) that evolved to scarring alopecia with tufts of 20 to 30 apparently normal hair shafts. Read More
