A Case of Generalized Lichen Sclerosus et Atrophicus

ABSTRACT

A 62-year-old female, with previous history of asthma andhypertension, presented with generalized hyperpigmentedskin lesion, found a year ago. Physical examination revealedbrown colored lichenified and sclerotic patches on the lowerabdomen and flexural areas of extremities. Punch biopsywas performed and histopathological examination revealedhyperkeratosis, follicular plugging and thinning in epidermis.In dermoepidermal junction, cleft like space separating atrophicepidermis and dermis was seen. Also, lichenoid lymphocyticinfiltration was observed in mid-dermis. Based onclinical and histopathological findings, a diagnosis of generlaizedlichen sclerosus et atrophicus (LSA) was made.Other laboratory examinations were unremarkable. As thereis no standard treatment for LSA, the patient received varioustreatments including topical steroid, tacrolimus and narrow-band ultraviolet B therapy. The skin lesion has softenedand its color improved after treatment. LSA is defined as infrequentchronic inflammatory dermatosis with anogenitaland extragenital manifestations. Generalized type is rare andgenital involvement is the most frequent and often the onlysite of involvement. We report this case as it is an uncommontype of LSA with generalized hyperpigmented and scleroticskin lesion in a postmenopausal female patient.
