A 70-year-old woman presents with a progressive linear depression on her forehead. Learn about this rare form of localized Scleroderma and its diagnosis.
A 70-year-old woman with a history of hypothyroidism presented to the dermatology clinic with a 1-year history of progressive indentation and darkening of the skin of her forehead. The skin changes had occurred along a wrinkle that had been present for 10 years. On physical examination, a paramedian, linear, atrophic depression with a violaceous border was observed on the right side of the forehead. The depression extended from the orbital rim to the frontal scalp and was associated with cicatricial alopecia. Examination of a skin-biopsy specimen of the depression revealed a perivascular infiltrate of lymphocytes, eosinophils, and plasma cells, along with vacuolar interface dermatitis and dermal scarring.
