Lump in the breast may occur due to fibroadenoma (a benign tumor of the breast, which is usually a firm solitary mass that is mobile beneath the skin) or beast cancer (a malignant tumor of the breast, which is adherent to underlying tissue and immobile).
  2. The peau d’orange appearance of skin (i.e skin like an orange peel)is due to the retraction of pits of hair follicles beneath the edematous skin following the retraction of ligaments of cooper. The condition is due to the blockage of lymphatics draining the skin, leading to the stagnation of lymph and edema of skin.
