Abstract

Summary: Centrifugal lipodystrophy (CLD), characterized by a depressed lesion in the abdominal skin, is a chronic disease occurring more often among younger patients of East Asian descent. We present an extremely unusual case of CLD of the scalp associated with reversible hair loss. The patient demonstrated alopecia in the frontal, temporal and occipital areas of the scalp, which connected to form a ring‐shaped area of hair loss. Curiously, the area of hair loss gradually expanded outwards while the central region showed normal hair regrowth. Immunohistochemical analysis demonstrated reduced expression of leptin, an adipokine capable of inducing the anagen phase of the hair cycle, in the adipose tissue, associated with active inflammation. By contrast, recovery of leptin expression was observed at sites of healed inflammatory lesions, suggesting that reversible hair loss might be caused by a change in leptin expression in adipose tissue.
