Lichen Sclerosus et Atrophicus with Multiple Distribution and Hemorrhagic Change / 대한피부과학회지

ABSTRACT

Lichen sclerosus et atrophicus (LSA) is a benign, chronic inflammatory mucocutaneous disease of unknown etiology with a predilection for the female genital area, which is highly bothersome. It may also involve other areas, mainly the upper trunk, axillae and buttocks and clinicians often make a misdiagnosis of these extragenital lesions due to their rarity and lack of symptoms. We herein report the case of a 69-year-old female patient with multiple extragenital LSA presenting with hemorrhagic change. Histopathologic evaluation showed follicular plugging, atrophy of stratum malpighii with hydropic degeneration of basal cells, prominent upper dermal edema and lichenoid lymphocytic infiltration in the mid dermis which was consistent with LSA. We remind clinicians of including LSA in the differential diagnoses of multiple cutaneous hemorrhagic lesions.
