## TL;DR

A parotid tumor can be a sign of relapsed breast cancer, even after years of remission, highlighting the importance of recognizing this rare metastatic pathway.

## Contribution

The paper highlights a rare metastatic pathway of breast cancer to the parotid gland, emphasizing the need for clinical awareness.

## Key findings

- Parotid tumor can be the first sign of relapsed breast cancer years after remission.
- Recognizing atypical parotid masses in breast cancer survivors can lead to timely diagnosis and better outcomes.

## Abstract

Parotid tumor can be the first manifestation of relapsed breast cancer, even years after remission. Awareness of this rare metastatic pathway is crucial, as timely recognition of atypical parotid masses in patients with a breast cancer history can guide prompt diagnosis and improve management outcomes.
