title: A case of T1N0M0 vulvar apocrine gland carcinoma with a positive outcome.
abstract: BACKGROUND
  Apocrine carcinoma of the vulva is extremely rare; only two cases have been reported worldwide. Here we report a case of apocrine carcinoma of the vulva.
  
  
  METHODS
  A 58-year-old woman complaining of a small, asymptomatic genital tumor visited the gynecology clinic of Chiba Social Insurance Hospital. The biopsy specimen suggested that it was an adenocarcinoma derived from the apocrine gland. The diagnosis was confirmed by periodic acid-Schiff staining and immunohistochemical staining for gross cystic disease fluid protein 15. She underwent simple vulvectomy with hemilateral groin dissection. She has been followed as an outpatient for the past 7 years with no signs of recurrence or metastasis.
  
  
  CONCLUSIONS
  Despite the positive outcome of this case, small, asymptomatic genital lesions should be regarded with caution.
