“…[ 4 ] Frictional alopecia is a type of traumatic alopecia caused by repeated rubbing of the skin underlying the affected hair. [ 5 6 7 ] It has been described on sites such as the lower extremities in the distribution of socks and shoes, and the scalp in gymnasts and joggers. [ 6 7 ] Trichoscopy provides useful clues in the diagnosis of frictional alopecia.…”

Post herpetic itch (PHI) is a less commonly reported sequela of herpes zoster. It can begin upon the resolution of the lesions or several weeks later. PHI is neuropathic in nature and is said to be caused by neural injury in the form of demyelination of itch-transmitting nerve fibers in the skin. The majority of PHI resolves over weeks to months with symptomatic treatment. We report a case of PHI resulting in frictional alopecia of eyebrows and scalp due to frequent rubbing of the skin and hairs secondary to bothersome neuropathic itch.

“…Non-invasive modalities such as dermoscopy are a useful diagnostic aid [Figure 10a]. 5,7,31,[78][79][80][81] In addition, patch and photo patch testing may be helpful to rule out contact dermatitis, an important differential. Diagnostic dilemma and differentiation from clinical mimics may warrant a skin biopsy [Figure 10b].…”

Human skin is continually exposed to internal and external forces, dynamic as well as static. The skin is normally flexible and can resist mechanical trauma due to friction, pressure, vibration, suction and laceration to a considerable degree. However, an excess of these forces can abnormally affect the structure and function of the skin, setting the stage for the development of a skin disorder. Repetitive trauma can cause lichenification, hyperpigmentation, erythema, scaling, fissuring, blisters, ulceration and chronic alterations. Frictional dermatoses is an under-recognised entity with no clear-cut definition and encompasses a variety of terms such as frictional dermatitis, frictional melanosis, frictional pigmentary dermatoses and certain other named entities, many of which are confusing. The authors propose to define frictional dermatoses as ‘a group of disorders caused by repetitive trauma to the skin as a result of friction of varied aetiology which can have a wide range of cutaneous manifestations depending on the type of insult.’ The exact prevalence of frictional dermatoses as a separate entity is unknown. Authors who conducted this review include a group of dermatologists and post graduate students from various institutions. Literature was reviewed through PubMed, Medscape, Medline, ResearchGate and Google Scholar using the terms ‘frictional dermatitis,’ ‘friction and skin,’ ‘dermatoses and culture,’ ‘clothing dermatitis,’ ‘friction melanosis,’ ‘PPE induced dermatoses in COVID-19 era,’ etc. A total of 122 articles were reviewed and 100 articles among them were shortlisted and included in the study, after removing duplications. The review was followed up with further deliberation which resulted in the formulation of a new definition and classification of frictional dermatoses taking into account the morphology, histopathological characteristics, anatomical region affected and the major predisposing factors. The rising incidence of mechanical dermatoses in the COVID-19 era was also emphasised.
