title: [Palisading granuloma of the penis: a variant of subcutaneous granuloma annulare].
abstract: BACKGROUND
  Subcutaneous granuloma annulare on the penis has only been reported exceptionally.
  
  
  METHODS
  A 41 year-old man presented with four small, asymptomatic nodules on the glans penis. Histological examination of a biopsy revealed a deep palisading granuloma progressing not only around the alcian-blue necrobiosis areas but also around the smooth muscle fibers. The lesion regressed spontaneously after two years of progression.
  
  
  CONCLUSIONS
  Palisading granuloma of the penis appears to be a most particular clinical form of subcutaneous granuloma annulare. It is characterized by small single or multiple nodules localized on the penis. On histological examination, the granuloma is deep and concentrates around the network of smooth muscle fibers of dartoic origin.
