Background:

Dermatofibrosarcoma protuberans (DFSP) is a rare, low-grade malignant skin tumor.
Accurate diagnosis is crucial for appropriate treatment and prognosis.
Molecular markers can aid in the definitive diagnosis of DFSP.

Observation:

A 57-year-old woman presented with a breast tumor.
The tumor was clinically suspected to be dermatofibrosarcoma protuberans (DFSP).

Findings:

Molecular analysis was performed on the patient's tumor tissue.
The characteristic COL1A1-PDGFB gene fusion, a hallmark of DFSP, was detected.
This molecular finding confirmed the diagnosis of DFSP.

Implications:
