    Paget's disease
  23. What determines the prognosis of Paget's disease?
    extent of ductal cancer
  24. Palpable lumps that can vary during menstrual cycles
    fibrocystic changes
  25. Blue dome cysts containing turbid fluid
    cysts and fibrosis
  26. Cysts lined by cells with granular pinkish eosinophilia
    Apocrine metaplasia, associated with cysts and fibrosis
  27. Proliferation of cells with a duct NOT producing a clinically discrete masses
    epithelial hyperplasia
  28. hard rubbery consistency
    sclerosis adenosis
  29. Masses of small gland patterns with firbous stroma
    sclerosing adenosis
  30. Discrete palpable, encapsulated, freely moveable with tan/white color
    fibroadenoma
  31. Leaf like, may be massive in size
    Phyllodes tumor
  32. Papillary growth withi a duct leading to bloody nipple discharge
    intraductal papilloma
  33. anaplastic cells that are proliferating within the DUCT, but do not permeate the BM
    Intraductal carcinoma
  34. difficult if not impossible to palpate
    lobular carcinoma in situ
  35. 3-4 cm stony hard consistency
    invasive ductal carcinoma
  36. Typical intraductal cancer that extends to and infiltrates the skin of the nipple and areola
    Paget's disease
  37. Large, soft, and fleshy
    Medullary carcinoma of the breast
  38. Soft, bulky, gray-blue mass
    Colloid (mucinous) carcinoma
  39. Poorly circumscribed, rubbery, difficult to palpate
    infiltrating lobular cancer of the breast
  40. Most common benign tumor of the breast
    fibroadenoma
  41. Age range affected by fibroadenomas
    3rd decade
  42. Fibroblastic stroma with duct like spaces
    fibroadenoma
  43. subareolar tumor
    intraductal papilloma
  44. rare to have nipple retraction
    intraductal papilloma
  45. necrotic tumor tissue in the middle of ducts
    comedocarcinoma, associated with intraductal carcinoma
  46. Most common form of breast cancer
    invasive ductal carcinoma
  47. Dense fibrous stroma (desmoplasia) with nests or cords of tumor cells that can cause nipple retraction and skin dimpling
    invasive ductal carcinoma
  48. Large cells not forming sheet like infiltration and lymphocytic infiltration
    Medullary carcinoma of the breast
  49. Strands of tumor cells one cell in width (Indian filing)
    Infiltrating lobular cancer of the breast
  50. Most common type of alteration in the breast
    non-proliferative change
  51. Clinical and morphologic features similar to a carcinoma
