Review Question - QID 213878

A 62-year-old woman presents to her primary care provider after noticing a hard lump in her left breast 2 weeks ago. The woman is gravida 2 para 2 and has no other medical conditions aside from hypothyroidism for which she is on daily levothyroxine. She is postmenopausal with her last menstrual period at age 54. Her last mammogram was 2 years ago and normal. The patient denies previous breast disease but does report that a few weeks ago her cat jumped onto her chest and left a bruise on her left breast. The patient’s temperature is 98.4°F (36.9°C), blood pressure is 110/76 mmHg, pulse is 72/min, and respirations are 12/min. On exam, the patient has an extremely firm mass in the upper outer quadrant of her left breast. The borders are not smooth, and the mass is nontender to palpation. There is no erythema or ecchymosis of the overlying skin, but there does appear to be some pinching of the skin. There is 1 palpable axillary lymph node. A mammogram demonstrates stellate calcifications, and the decision is made to pursue a biopsy. Which of the following most accurately describes the likely histological findings of this lesion?
