Lichen sclerosus et atrophicus of the scalp

Abstract

A patient is described who developed pruritic lesions of the scalp with increasing hair loss and plaque formation over a period of 15 years, in association with patches of white atrophic skin on her trunk and vulva in the last 5 years. Biopsies of the scalp and trunk lesions both showed lichen sclerosus et atrophicus. This would appear to be the first recorded case of lichen sclerosus et atrophicus of the scalp in the English literature.

Non‐Infective Cutaneous Conditions of the Vulva

“…Bullae, purpura, marked atrophy and pallor are frequent features. The lesions occur anywhere, including nails (Ramrakha- Jones et al 2001), scalp (Foulds 1980) and eyelid (Fig. 5.53).…”

“…Whimster (1973) noted that lichen sclerosus developed in a split-skin graft transferred to the vulva from the thigh, whereas vulval lichen sclerosus skin reverted to normal when transferred to the thigh. Lichen sclerosus may develop or recur not only in skin grafts (Foulds 1980) but also in a myocutaneous graft (di Paola et al 1982).…”

Secondary cicatricial and other permanent alopecias

“…The scalp can be affected in patients with multiple lesions (91). In one report, pruritic lesions caused extensive scarring alopecia (92). In another case, there was bullous Lichen sclerosis et atrophicos (LSA) with scalp involvement (93).…”

Peristomal lichen sclerosus developing posturostomy

“…The genitalia are most commonly affected 3 . Extra‐genital involvement usually occurs on the neck and shoulders, 3 but has been reported in other sites including the scalp, 4 palms and soles, 5 around the eye, 6 the oral mucosa and the tongue 7 . Peristomal LS is extremely rare.…”
