Glomangiosarcoma, or malignant glomus tumor, is a very rare neoplasm that when seen typically arises from a benign glomus tumor. Despite having histologic features of malignancy, these tumors usually do not metastasize. However, when metastasis occurs this disease is often fatal. We report a case of a malignant glomus tumor arising de novo on the nose of an 89-year-old white woman, and we review the literature concerning glomangiosarcomas.
