An unusual case of a glomus tumor developing in a subcutaneous vein of the wrist

Glomus tumors are benign tumors that originate in a neuromyoarterial glomus body and most commonly occur in the subungual regions. We present an unusual case of a glomus tumor in a subcutaneous vein of the dorsum of the wrist in a 65‐year‐old man and describe its gray‐scale and power Doppler sonographic appearance, with a brief discussion of the clinical and histologic findings. © 2008 Wiley Periodicals, Inc.
