title: Metastatic malignant ovarian melanoma--a case report.
abstract: BACKGROUND
  Malignant melanomas of the female reproductive system are rare. These are biologically highly aggressive tumors with poor prognosis. Preoperative establishment of the diagnosis is practically impossible. Therapeutic approach and treatment of patients with metastatic ovarian melanoma are highly dependent on precise histological analysis.
  
  
  METHODS
  A woman aged 48 was admitted to the clinic for occasional pains in the lower abdomen and suspected myomatous changes of the uterus. The patient underwent surgery for melanoma on her right arm five years ago. Classic hysterectomy with bilateral adnexectomy with infracolic omentectomy and selective iliac lymphadenectomy were performed. Macroscopic examination revealed an oval tumefaction on the left ovary sized 12.5 x 10 x 3.5 cm of solid structure. Tumor tissue was yellowish-brown colored, of solid structure and mostly localized subcortically with central edema. Microscopic examination showed positive reaction for HMB-45, anti-Melan-A and S-100 protein, but negative immunoreactivity for estrogen and progesterone receptors. Malignant disease caused death after a 4-year follow-up period following gynecological operation.
  
  
  CONCLUSIONS
  The previous diagnosis of skin melanoma is also indicative of metastatic ovarian tumor, while immunohistochemical analyses confirmed the histopathological diagnosis.
