title: Volar melanotic macules in a Japanese man with histopathological postinflammatory pigmentation: the volar counterpart of mucosal melanotic macules.
abstract: BACKGROUND
  Volar melanotic macules are asymptomatic light-brown or tannish-grey macules usually found on the palms and/or soles of blacks, although they have also been reported on the volar surfaces of whites. Similar lesions have not been reported before in Japanese people. Since the cause is as yet unknown, it remains to be discussed whether they are a distinct entity.
  
  
  METHODS
  In this report, a 52-year-old Japanese man with volar melanotic macules is reported with the clinical and histopathological findings.
  
  
  RESULTS
  A 52-year-old Japanese man presented with many light-brown macules on his bilateral soles. He had a 20-year history of tinea pedis. Histopathological examination revealed melanophages and inflammatory infiltrates in the superficial dermis. There was a slight increase in melanin granules around the acrosyringium. Fontana-Masson stain revealed a slight increase in melanin granules in the basal layer including the acrosyringium and superficial dermis. These changes corresponded with postinflammatory pigmentation.
  
  
  CONCLUSIONS
  This is the first report of volar melanotic macules in Japanese people. We suggest that volar melanotic macules is not an independent entity but a clinicopathological one that includes postinflammatory pigmentation, and that the condition is the volar counterpart of mucosal melanotic macules.
