Case 201: glomus tumor of the breast.

History A 55-year-old woman presented to our breast clinic with 1-year history of lancinating pain in the right breast that was exacerbated by blunt pressure and cold temperature. She denied any family history of breast cancer or any personal history of trauma, infection, or surgery of the breast. On clinical examination, exquisite pain was generated by simple light pressure over the upper outer quadrant of the right breast. Mammography and ultrasounography (US) with Doppler analysis of the right breast were painful but were performed with the least pressure possible.
