We aimed to describe a histopathologically proven intramammarian glomus tumor and presented mammographic and Doppler ultrasound findings. Glomus tumor is a relatively uncommon soft tissue tumor. It can occur at any age and anatomical site with a predilection for the subungual region. Usually there is no diagnostic difficulty for small, painful subungual nodules but it is more difficult in deep locations. The breast is a very uncommon location for a glomus tumor. Ultrasound characteristics of glomus tumors located in the hand region are known and published previously. With its slightly lobulated margins, lucent notch, and highly vascular nature, ultrasound characteristics of our case were rather different and not helpful when the other glomus tumors located in the hand region were considered.
