Abstract
|
|
|
|
Malignant glomus tumor, or glomangiosarcoma, is a very rare neoplasm that typically arises from a benign glomus tumor. Despite having the histological features of malignancy, these tumors usually do not metastasize. We report a case of malignant glomus tumor on the finger of an 18-year-old man. By histology, round to ovoid tumor cells showed a uniform appearance of round nuclei. Many mitotic figures and nuclear atypia were observed. Immunohistochemically, vimentin and alpha-smooth muscle actin showed intense staining. This case was considered to be a malignant glomus tumor. Thus, it was a glomangiosarcoma arising de novo.
