Peritoneal malignant mesothelioma with multiple distant skin metastases.

• Metastases in multiple distant sites, including the skin, developed in a 54-year-old man with diffuse malignant abdominal mesothelioma. To our knowledge, this represents the first reported case of cutaneous metastasis arising from malignant mesothelioma. Recent advances in diagnostic techniques, such as electron microscopy, may be helpful in differentiating this condition from metastatic adenocarcinoma. ( Arch Dermatol 1983;119:827-830)
