Folliculitis decalvans is an inflammatory presentation of cicatrizing alopecia characterized by inflammatory perifollicular papules and pustules. It generally occurs in adult males, predominantly involving the vertex and occipital areas of the scalp. The use of dermatoscopy in hair and scalp diseases improves diagnostic accuracy. Some trichoscopic findings, such as follicular tufts, perifollicu...

Treatment of folliculitis decalvans is a major challenge, with a great number of recurrences and required maintenance of disease activity over a long period. Laser-based hair removal has been used in the management of scarring follicular disorders. The present case report aims to illustrate the case of a patient bearing folliculitis decalvans in the lower limb who underwent five therapeutic ses...

BACKGROUND Androgenetic alopecia is characterized by a defined area of progressive nonscarring alopecia. The clinical and histological findings in 15 women and 4 men with progressive scarring alopecia in a pattern distribution were studied. The results were evaluated and compared with clinicopathologic entities that feature scarring of the central scalp area, specifically, lichen planopilaris, ...

Trichodysplasia spinulosa (TS) is a unique, rare clinical and histological dermatologic entity described mainly in setting of immunosuppression. It caused by novel human polymoavirus, trichodysplasia spinulosa-associated polyomavirus (TSPyV). We report biopsy-proven case TS renal transplant patient presented to dermatology outpatient clinic Montreal, Canada 2015. Reduction immunosuppression and...

Inverted follicular keratosis is a benign tumor of the skin that is believed to arise from the infundibular portion of the hair follicle above the level of entrance of the sebaceous duct. It was described originally by Helwig in 1954 and since then a number of case reports have been reported in the dermatology and pathology literature. A 55-year-old woman was referred for evaluation of a kerato...

Introduction: Keratosis pilaris(KP) is a disorder of keratinization of hair follicles characterized by keratin plugs in the hair follicles with perifollicular erythema.It may be inherited with X-Linked Dominant, or may be sporadic. Aim of the study: to compare the efficacy of 30% Salicylic acid and Long pulsed 1064nm Nd:YAG laser for treatment of keratosis pilaris. Materials and methods: Out of...

White sponge nevus (WSN) is a rare oral mucosal lesion first described by Cannon in 1935, characterized as benign leukokeratotic lesion of early onset with periods of remission and exacerbation. It is usually asymptomatic, although pruritus, burning, and pain have been reported following irritating stimuli.WSN is inherited as an autosomal dominant trait with wide variability of expression and h...

Darier's disease (DD, keratosis follicularis: OMIM#124200) is an autosomal dominant skin disorder characterized by multiple dark brown keratotic plaques and warty papules covered by thick crusts. Most cases of DD are caused by mutations in ATP2A2, which is expressed in both the skin and the brain. ATP2A2 encodes the cardiac muscle SERCA2a protein and the ubiquitously expressed SERCA2b. SERCA2 p...
