title: [Laparoscopic cholecystectomy in isolated gallbladder metastasis of malignant melanoma].
abstract: Metastasized malignant melanomas can affect all organs of the human body. However, isolated metastatic spreading into the gallbladder is rare. We treated two asymptomatic patients who had undergone primary curative resection of a melanoma. Gallbladder structures suggesting the presence of tumors were noticed in the follow-up investigations. The two patients underwent laparoscopic cholecystectomy to clarify their pathological relevance. Histologically, the tumor was a metastasis of the malignant melanoma in each case. Surgery is indicated in stage IV in isolated metastatic spreading to the gallbladder in order to avoid symptoms or tumor complications. Since the vast majority of melanoma metastases of the gallbladder are located intraluminally and lymphadenectomy in the region of the hepatoduodenal ligament does not appear to be appropriate, the operation should be carried out laparoscopically. The value of postadjuvant chemoimmunotherapy after metastasis resection is being investigated in numerous studies at present.
