title: A rare tumor of the face: malignant nodular hidradenoma with dermoscopic features mimicking amelanotic melanoma.
abstract: BACKGROUND
  Sweat gland neoplasms are rare neoplasms with less known dermoscopic features.
  
  
  METHODS
  By applying dermoscopy, we identified some common vascular features that have been defined for amelanotic melanoma such as hairpin vessels, dotted vessels, linear irregular vessels, glomerular vessels, and milky-red areas.
  
  
  CONCLUSIONS
  Polymorphic vascular structures can also be seen in eccrine neoplasms. Further evaluations should be done to differentiate and identify the common dermoscopic features of other sweat gland tumors.
