title: Chondroid syringoma with small tubular lumina.
abstract: BACKGROUND
  Chondroid syringoma or mixed tumor of the skin is a rare epithelial tumor with eccrine differentiation. The variant with small tubular lumina is extremely uncommon.
  
  
  OBJECTIVE
  Chondroid syringoma is usually present as a single subcutaneous nodule. This report describes a man with multiple scalp lesions exhibiting features of chondroid syringoma with small tubular lumina.
  
  
  METHODS
  A Pathological examination of surgically resected multiple scalp nodules was carried out by routine histology and immunohistochemistry. The following antibodies were found: cytokeratin, epithelial membrane antigen, and vimentin.
  
  
  RESULTS
  Microscopic findings revealed multiple chondroid syringoma with small tubular lumina. The tumor cells were positive for high- and low-molecular-weight keratin, epithelial membrane antigen, and vimentin.
  
  
  CONCLUSIONS
  This is the first report of multiple chondroid syringoma with small tubular lumina.
