title: Granuloma faciale: a clinicopathologic study of 66 patients.
abstract: BACKGROUND
  Only case reports or studies of small series of patients have focused on granuloma faciale (GF).
  
  
  OBJECTIVE
  We sought to describe the clinicopathologic characteristics of GF in a large series of patients.
  
  
  METHODS
  We conducted a retrospective analysis of 66 patients and 73 skin specimens.
  
  
  RESULTS
  GF mostly presented as reddish plaques or nodules in middle-aged adults. One third of patients had multiple sites involved and 5 patients had extrafacial lesions. A clinical diagnosis of GF was made in only 10 cases; sarcoidosis, lymphoma, lupus, and basal cell carcinoma were the main differential diagnoses. The most frequent histopathologic features were the presence of a grenz zone, neutrophils, and telangiectases. Vascular changes were frequent, although necrotizing vasculitis appeared to be rare. There was often an association of acute and chronic inflammatory patterns, suggesting that GF follows a chronic history with recurrent acute phases, rather than distinct successive acute and chronic stages.
  
  
  CONCLUSIONS
  In this retrospective study, a reliable analysis of the outcome of patients could not be performed. Results of direct immunofluorescence tests and laboratory investigations were lacking in many cases.
  
  
  CONCLUSIONS
  GF is often clinically misdiagnosed; its morphologic spectrum is broader than usually described and includes a lack of eosinophils, the presence of vascular changes with rare vessel wall necrosis, and associated acute and chronic inflammatory patterns.
