Woman finds lump on breast, comes into clinic. Physical exam shows dimpling over mass. Mammography shows 4 cm mass over low lateral quadrant. Dimpling of skin is most likely due to traction of the tumor on which of the following structures?
a) branches of cutaneous pectoral nerves
b) lactiferous ducts
c) mammary arteries and veins
d) mammary lymphatics
e) suspensory (cooper) ligaments
I put mammary lymphatics because I thought breast dimpling meant peau d'orange which is caused by obstruction of lymphatic drainage, but this was not the answer. What exactly is this question talking about here?
