Summary
Columnar cell lesions, common in mammography biopsies, may be early precursors to low-grade breast cancer. However, their risk of recurrence or progression to invasive cancer is very low.
Area of Science:
- Breast pathology
- Oncology
- Diagnostic imaging
Background:
- Columnar cell lesions (CCL) are increasingly found in mammography-guided biopsies.
- They are characterized by dilated acini lined with columnar epithelial cells.
- A subset exhibits cytological atypia, prompting further investigation.
Purpose of the Study:
- To review recent clinicopathological and molecular data on columnar cell lesions.
- To discuss changes in the perception and classification of CCL.
- To provide management guidelines for CCL diagnosed in core needle biopsies.
Main Methods:
- Literature review of observational and molecular genetic studies.
- Analysis of clinicopathological data.
- Synthesis of current understanding and classification systems.
Main Results:
- CCL are prevalent in mammographic microcalcification assessments.
- Evidence suggests some CCL may be early precursors to low-grade breast carcinomas.
- The risk of local recurrence and progression to invasive cancer is notably low.
Conclusions:
- Columnar cell lesions represent a spectrum of breast pathology with potential, albeit low, malignant risk.
- Updated understanding has refined their classification and clinical management.
- Guidelines for managing CCL in core needle biopsies are essential.
