title: Microcystic adnexal carcinoma of the eyebrow.
abstract: OBJECTIVE
  To describe a case of the largest reported microcystic adnexal carcinoma of the eyebrow in an 89-year-old woman and to review the literature regarding the periorbital occurrence of this tumor.
  
  
  METHODS
  Case report and literature review.
  
  
  RESULTS
  This case was treated with primary excision and radiotherapy, with no clinical signs of recurrence in the past 6 months.
  
  
  CONCLUSIONS
  Microcystic adnexal carcinoma is a rare tumor; however, because of its aggressive local infiltration, ophthalmologists should consider this diagnosis and complete surgical excision. Long-term data are needed to establish outcomes from the different treatment options.
