Abstract

Malignant transformation of glomus tumor is exceedingly rare and most common reported in lower extremity and abdominal viscera. We could find only 6 previous case report of malignant glomus tumor in the hand. Although large and deeply located glomus tumors are considered to be malignant, evidence has shown that most of these cases were clinically benign. These lesions are better considered as glomus tumor of uncertain malignant potential. Due to rarity of malignant glomus tumor, decision for operative treatment must be based on few case reports. In this article we review the literature for malignant glomus tumor of hand and their management, also we report a 49 year-old man with glomus tumor of uncertain malignant potential in thumb who was treated by wide amputation.
