“…The repetitive rubbing of the scalp has led to LSC in our patient evidenced by the presence of background hyperpigmentation and perifollicular scaling in trichoscopy. [ 6 ] Broom hairs were recently considered a hallmark finding in trichoteiromania which is a compulsive disorder of rubbing of hair. [ 7 8 ] Fowler and Tosti[ 9 ] reported a case of frictional alopecia presenting as trichorrhexis nodosa on trichoscopy.…”

Scalp dysesthesia (SD), a variant of cutaneous dysesthesia syndrome is an underrecognized cause of scalp pruritus. It usually presents with itch, pain, burning, or stinging sensation over localized or diffuse area of the scalp without any objective findings. Trichoscopy, a rapid and in-office procedure, could aid in the early clinical diagnosis of this condition and initiate management. We report a case of SD in an elderly male diagnosed with the aid of trichoscope, evaluated and treated successfully.

Scalp dysaesthesia, considered a variant of the cutaneous dysaesthesia syndrome, is characterized by chronic sensory symptoms, including pruritus, pain, burning and stinging in a well-defined location, without objective findings. Its aetiology is not well elucidated and treatment options are limited, thus it can be challenging and frustrating for both patient and physician. It can be associated with lichen simplex chronicus. In this paper, we review the literature on the pathogenetic factors, diagnostic methods and therapeutic options in the management of scalp dysaesthesia. Dissociation, cervical spine disease and muscle tension seem to be the most important pathogenetic factors. Trichoscopy, reflectance confocal microscopy and biopsy are all helpful for the diagnosis of the disease. Therapies include high-potency topical or intralesional corticosteroids, capsaicin and topical anaesthetics, sedative antihistamines, tricyclic antidepressants, transcutaneous electric nerve stimulation, botulinum toxin and vitamin B12.

Lichen simplex chronicus of the scalp: dermoscopy and reflectance confocal microscopy featuresDear Editor, Scalp lichen simplex chronicus (LSC) is rare and can be a challenging and frustrating condition for both patient and physician. Dermoscopic features of LSC have already been described and correlated to histopathology, 1-3 but diagnosis may results difficult even with the aid of dermatoscopy and the pathologic interpretation may not be diagnostic if biopsy is not obtained from the correct site.We collected 19 patients (52.6% females) with biopsy-proven LSC from different countries. In two cases, reflectance confocal microscopy (RCM) was also performed by one of the authors (V.D.M.) using the VivaScope â 3000 (Mavig GmbH, Munich, Germany), which allows to scan an area of 1 9 1 mm up to a depth of 200 lm. Instrument and acquisition procedures have been described elsewhere. 4,5 Vertical VivaStack software imaging was used for the evaluation of adnexal structures from the ostium to the maximum depth. RCM images assessments were performed jointly on a highresolution monitor by two authors (V.D.M. and G.P.
