An ultrastructural and immunohistochemical study of cutaneous metastasis of biliary system carcinoma

Abstract

An 81-year-old Japanese man noticed red papules and subcutaneous tumors on his face and trunk about 2 months before entering our clinic. He had been suffering from biliary system cancer for about one year.Light microscopic findings: Tumor cells, which formed various-sized glands lined by columnar cells, were observed in the dermis and subcutaneous tissue.Electron microscopic findings: In tumor cells, intracytoplasmic lumina lined with microvilli were observed. Cell organelles, such as mitochondria and rough-surfaced endoplasmic reticulum, were relatively well-developed. From these findings, it seems that the characteristics of these tumor cells resemble those of the biliary system.
