[Acute liver failure in metastatic melanoma]. 
Only seven cases of occult malignancy clinically presenting as acute liver failure due to liver metastases have been outlined in literature so far.  In six cases the primary tumor originated histomorphologically from pancreas, bronchus or mamma, in one case the patient died before histological diagnosis.  This case report describes the only ten days lasting anamnesis of a 42-year-old man, who felt completely healthy before.  Only the autopsy and the immunohistological staining of the taken biopsies led to the diagnosis of an amelanotic melanoma.  The site of the primary lesion remained unclear.
