title: Expression of cyclin D1 and p53 protein in various malignant skin tumors.
abstract: BACKGROUND
  Overexpression of cyclin D1 and p53 protein has been reported in many types of malignant tumors.
  
  
  OBJECTIVE
  We investigated whether cyclin D1 was detected immunohistochemically in various types of malignant tumors of the skin, comparable with p53 protein.
  
  
  METHODS
  Immunohistochemical staining of cyclin D1 and p53 protein was applied to squamous cell carcinoma, malignant melanoma and malignant fibrous histiocytoma and various kinds of benign skin tumors.
  
  
  RESULTS
  Cyclin D1 was positive only in malignant tumors at the same incidence as p53 protein.
  
  
  CONCLUSIONS
  Cyclin D1 immunohistochemical staining may be a malignant marker for various skin tumors.
