## TL;DR

A rare case of chronic lymphocytic leukemia affecting both breasts is reported, highlighting its unusual extranodal presentation.

## Contribution

This case report presents a rare bilateral breast manifestation of chronic lymphocytic leukemia.

## Key findings

- Mammography identified large, lobulated masses in both breasts.
- Histopathology confirmed chronic lymphocytic leukemia involvement in the breast tissue.
- The case highlights the importance of considering CLL in breast mass evaluations.

## Abstract

Mammography revealed a large, lobulated, hyperdense mass in the right breast occupying nearly the entire breast and axillary region. A smaller but similar lobulated mass was present in the upper outer quadrant of the left breast. BIRADS 4 classification was assigned to both breasts, indicating suspicious findings requiring further evaluation. Based on histopathologic evaluation, it was found that the breast was involved by chronic lymphocytic leukemia.
