A 16-year-old female presented to a family medicine clinic for evaluation of increasing right breast pain associated with a right breast mass. The patient had a 2-day history of right breast pain associated with a breast mass that had been present for approximately 8 months. The mass first appeared after she was hit in the right breast during a fight at school. At that time, she did not see any bruising of the breast, nor did she feel significant pain. The mass had grown in size over the preceding 8 months. The patient did not report associated skin erythema or dimpling, nor was there nipple discharge.
