We present the case of a 69-year-old man with a subcutaneous pleomorphic hyalinizing angiectatic tumor of soft parts on the back. In addition to its rare localization, it showed unique clinical features of an exceptionally long history. Histological characteristics of this tumor showed thin-walled angiectatic blood vessels lined with a thick eosinophilic and hyalinotic amorphous material. Tumor cells are composed of pleomorphic cells. It was surgically removed, and there was no recurrence by 11 months postoperatively.
