Distant cutaneous metastasis of pleural malignant mesothelioma

Abstract

We report a facial tumor that was proven to be a metastatic: mesothelioma. The diagnosis was not established pre‐mortem. The patient died shortly after the facial biopsy, and an autopsy revealed a large pleural‐based mass which had the gross appearance typical of a mesothelioma. Electron microscopic examination of tissue from the pleural tumor was diagnostic for mesothelioma. The patient had extensive visceral metastatic disease. Inclusion of this entity in the differential diagnosis of certain cutaneous tumors is important, in part because this lesion may be confused with angiosarcoma, particularly when it occurs in the skin of the face or head in older patients.
