title: Uterine metastasis from vulvar malignant melanoma. A case report.
abstract: BACKGROUND
  Malignant melanoma is the second most common vulvar malignancy. The superficial inguinal lymph nodes are the main site of metastases. Endometrial metastasis of vulvar malignant melanoma has not been previously reported.
  
  
  METHODS
  Vulvar malignant melanoma was diagnosed in a 60-year-old, postmenopausal woman. Immunohistochemical stains were positive for vimentin and S-100 protein and negative for HMB-45. Six months following vulvectomy, right inguinal lymphadenectomy and immunotherapy, curettage was performed due to postmenopausal bleeding. Histologic and immunohistochemical examinations revealed metastatic malignant melanoma with the same staining reactivity as the primary vulvar neoplasm had. Hysterectomy and bilateral salpingo-oophorectomy was performed, disclosing invasion of the endometrium and the inner two thirds of the myometrium.
  
  
  CONCLUSIONS
  Only 10 other cases of endometrial metastases from malignant melanoma have been previously reported. All those cases involved a primary tumor occurring in the trunk and extremities. This is presumably the first report on endometrial and myometrial metastases from vulvar malignant melanoma.
