BACKGROUND Lichen planopilaris is a frequent presentation of primary cicatricial alopecia. Scalp distribution characterizes the main clinical presentations: classic lichen planopilaris, frontal fibrosing alopecia and Graham-Little Piccardi-Lassueur Syndrome (GLPLS). OBJECTIVE Description of the clinical, dermoscopic and histopathological findings of Lichen planopilaris in public and private p...

Skin of color comprises a diverse and expanding population of individuals. In particular, women of color represent an increasing subset of patients who frequently seek dermatologic care. Acne, melasma, and alopecia are among the most common skin disorders seen in this patient population. Understanding the differences in the basic science of skin and hair is imperative in addressing their unique...

Dissecting cellulitis of the scalp or dissecting folliculitis also known as "perifoliculitis capitis abscedens et suffodiens" (PCAS), is a rare, severe and distinct dermatological disease. It most probably occurs because of follicular occlusion via hyperkeratosis, having the same mechanism of acnea conglobata and hidradenitis suppurativa. These dermatoses may be associated or may have an isolat...

cia would be easy and each biopsy would demonstrate the descriptions found in my new text. As my training progressed, I was fortunate to attend alopecia clinics in the dermatology department and see the corresponding biopsies during residency and in fellowship. Usually, the biopsies were expertly performed, grossed, and diagnosed, again, making the process seem exciting and deceptively easy. In...

BACKGROUND Immune responses are largely regulated by cytokines that are secreted by activated T cells. Interactions among these cells are complex, and the interaction between 2 responses may alter the effect of either response alone. It has been established that contact sensitization-induced inflammation can reverse hair loss due to alopecia areata. In parallel, the Renbök phenomenon demonstrat...

A utoimmune diseases probably have a multitude of causes. It is obvious that exogenous agents, particularly drugs, may trigger the development of autoimmune responses leading to bullous eruptions. In the literature several cases of drug-induced (disseminated) bullous pemphigoid (BP) have been reported (see article by Fellner in this issue); however, localized variants of pemphigoid and acquired...
