title: Nasolacrimal duct obstruction secondary to dermatofibrosarcoma protuberans.
abstract: OBJECTIVE
  To describe a patient wtih dermatofibrosarcoma protuberans causing a nasolacrimal duct obstruction (NLDO).
  
  
  METHODS
  Case report.
  
  
  METHODS
  A 33-year-old female with an NLDO.
  
  
  RESULTS
  We report a patient with NLDO as the presenting sign of a rare tumor of the skin, dermatofibrosarcoma protuberans. The patient presented with epiphora, and after dacryocystorhinostomy was done, histopathology revealed dermatofibrosarcoma protuberans. The clinical course, magnetic resonance imaging, and histopathology are discussed.
  
  
  CONCLUSIONS
  Obstruction of the lacrimal drainage system can be seen with dermatofibrosarcoma protuberans.
