Only a few cases of scrotal infiltration by a contiguous ACRT have been described. To our knowledge, none have reported distant skin metastases. We report a case of ACRT presenting with suprapubic skin metastases. The diagnosis was based on clinical and histopathological findings and supported by the results of immunohistochemical and ultrastructural studies. We discuss the differential diagnosis to this rare entity, which include metastatic adenocarcinoma, serous tumor of the testis, and mesothelioma of the tunica vaginalis.展开更多
