1.3 Superficial dissection, female pectoral region

  • On the specimen’s right side, the skin is removed; on the left side, the breast is sagittally sectioned.
  • The breast extends from the 2nd to the 6th ribs. The axillary process (tail) of the breast consists of glandular tissue projecting toward the axilla.
  • The region of loose connective tissue between the pectoral fascia and the deep surface of the breast, the retromammary bursa, permits the breast to move on the deep fascia.
  • Interference with the lymphatic drainage by cancer may cause lymphedema (edema, excess fluid in the subcutaneous tissue), which in turn may result in deviation of the nipple and a leathery, thickened appearance of the breast skin. Prominent (puffy) skin between dimpled pores may develop, which gives the skin an orange-peel appearance (peau d’orange sign). Larger dimples may form if pulled by cancerous invasion of the suspensory ligaments of the breast.
