| anonymous | Intraductal papilloma with focal atypia | perform immunostaining of neuroendocrine marker such as Syn,CgA,NSE to rule out neuroendocrine DCIS | 80 |

| anonymous | Intraductal papilloma with atypical ductal hyperplasia; Fibrocystic change in adjacent area | nil | 80 |
| anonymous | Ductal papilloma with florid epithelial hyperplasia. | The hyperplatic nature of the epithelial proliferation can be confirmed with immunostaining for estrogen receptor (ER) and high molecular weight cytokeratin (HMCK) (strong, diffuse HMCK and weak, heterogeneous ER in hyperplasia; strong uniform ER and weaker and non-uniform HMCK in low grade DCIS). Staining with myoepithelial markers (e.g. p63) will highlight the two cell types arrangment. | 100 |
| anonymous | SOLID PAPILLARY CARCINOMA (Neuroendocrine ductal carcinoma in situ). | Sampling to exclude invasion. DDX: Florid epitheliosis on intraduct papilloma. Look for monotonous ER staining and loss of HMWCK staining for DCIS. | 50 |
| anonymous | Duct papilloma with florid epithelial hyperplasia (100%) & Columnar cell change/hyperplasia (100%) | nil | 100 |
| anonymous | Breast - Low grade DCIS in papillomas 90% - ADH in papillomas 10% | Do immunostains CK14, ER. Diminished CK14 staining among proliferating ductal cells favor ADH/DCIS. More sampling to determine the size of lesion will determine if it is DCIS. | 50 |

| anonymous | Intraduct papillary neoplasm with florid usual hyperplasia (epitheliosis) and focal atypia 100% | Perform immunohistochemical study for neuroendocrine markers (Synaptophysin, Chromogranin) and examine more blocks to exclude micro/overt invasion. | 80 |
| anonymous | Papilloma with adenomyoepitheliomatous focus/usual ductal hyperplasia (100%) | Perform immunostaining for p63 to highlight the myoepithelial component. | 100 |
