title: Malignant papillary mesothelioma of the tunica vaginalis testes: cutaneous metastases showing pagetoid epidermal invasion.
abstract: Malignant papillary mesothelioma of the tunica vaginalis testis is an extremely rare tumor arising from the mesothelium of the tunica vaginalis. A total of 14 cases have been reported, with only two exhibiting cutaneous metastases. We present a third case of cutaneous metastases arising from this unusual tumor. In addition, this is the first reported case of the occurrence of pagetoid epidermal invasion in this condition.
