A 37-year-old female with past medical history of Vitamin D deficiency presented for an annual physical exam. She was concerned about a lump in her right breast that she had first noticed about 2 months prior. She noted that the skin overlying the lump had become discolored over the past 2 months, it was sometimes tender, and the lump had been growing in size. She had no family history of breast cancer. At age 16, she had a benign breast lump in the same breast. The lump was removed at that time and an implant was placed in her right breast. The implant was then removed 2 years later, at age 18. Her last mammogram 2 years prior was normal.

Vitals were normal. On exam, around 10:00 of her lateral right breast, there was a 7 cm × 7 cm indurated area, with a central 5 cm × 3 cm area of discoloration. The lesion was purple-colored and erythematous, with central puckering .

The breast mass and associated skin changes were highly suggestive of breast cancer. The patient was referred to a breast surgeon the following day for biopsy. The mass was found to be cancerous, and the patient eventually underwent chemotherapy, a right modified radical mastectomy, and radiation therapy.
