The various appearances of benign papillomas (cont). Papillary lesions associated with epithelial cell proliferation/atypia/LCIS/Grade 1 in situ carcinoma. Intracystic benign and malignant papillary growth. Papillary carcinoma.
The following imaging options will be demonstrated:
1. When nipple discharge is the only finding, galactography will be able to demonstrate the lesion(s) as detailed in two consecutive lecture segments (8 min and 10 min). The lectures consist of 11 histologically proven cases.
2. When there is a mammographically demonstrable, but non-palpable mass without associated calcifications and nipple discharge is present. Six cases with galactographic-histologic correlation (one segment, 11 min)
3. When papillary lesions are associated with one or more of the following: epithelial cell proliferation/atypia/LCIS/Grade 1 in situ carcinoma. These may be either mammographically occult or demonstrable. This lecture provides practice with three cases (one segment, 10 min)
4. When benign papillomas and micropapillary carcinoma in situ occur side by side. This lecture provides mammographic-3D histopathologic correlation in one case (one segment, 9 min)
5. When there is a non-calcified circular/oval-shaped mass on the mammogram. This lecture provides demonstration of one papillary cancer case (one segment, 7 min)
6. When there is a palpable, circular/oval-shaped tumor mass without associated calcifications and there is no nipple discharge present. This is a typical presentation of intracystic papillary tumors. There are five cases with histopathologic-mammographic correlation in this lecture (one segment, 12 min)
7. Five cases of malignant papillary lesions for practicing the teaching points outlined in the previous segments (one segment, 11 min)
