Description:
Papillary lesions of the breast are a source of recurring diagnostic difficulty in daily practice. In this presentation, a two-part conceptual framework that differentiates between papillomas involved by secondary proliferations and papillary carcinoma is emphasized. Application of this framework permits improved understanding of the histologic features of these complex lesions and thus facilitates diagnostic accuracy. Papilloma, papilloma involved by atypical hyperplasia, papilloma involved by in situ carcinoma, papillary ductal carcinoma in situ, encapsulated papillary carcinoma, and solid papillary carcinoma will be discussed. The uses and limitations of myoepithelial cell markers in diagnostic evaluation will be reviewed, as will contemporary issues and controversies regarding classification and management.
After attending this session, participants will be able to:
- Analyze papillary lesions using a two-part conceptual framework.
- Recognize the uses and limitations of myoepithelial cell markers in the evaluation of papillary lesions.
- Discuss contemporary issues regarding classification and staging of encapsulated papillary carcinoma and solid papillary carcinoma.
Who should attend? Practicing Pathologists, Residents, Doctoral Scientists, Pathologists’ Assistants
