Abstract
High variability of the clinical appearance of malignant melanoma (MM) and its metastases render the differential diagnosis of solid amelanotic tumours difficult. We report a 71-year-old woman with several unusual cutaneous tumours of cerebriform morphology, suggesting skin metastases from occult internal cancer. Histopathological findings and thorough investigations, however, revealed a late-stage metastatic MM. We discuss the differential diagnosis of skin metastases of various origin and underline the difficulties for early detection of MM.
