[Isolated metastasis in the gallbladder from malignant cutaneous melanoma discovered by ultrasound]

The authors describe the metastasis in gallbladder of the malignant melanoma removed from dorsal skin. Due to the increasing incidence of dermal melanomas, they emphasize the occurrence of unexpected and unpredictable metastases and the need for a close, life-long follow-up of patients. The prognosis of visceral metastases is affected to a great extent by their early detection.
