Background:
Dermatofibrosarcoma protuberans (DFSP) is an uncommon cutaneous soft tissue neoplasm with a tendency to recur but rarely metastasize. It occurs at almost any site but usually in the trunk and extremities. DFSP mimicking a primary breast lesion has not been reported before.
Case:
A 30-year-old female presented with an eight-month history of a breast mass that was aspirated, revealing a spindle cell neoplasm. The diagnosis of DFSP was made on excisional biopsy.
Conclusion:
The diagnosis of DFSP may be problematic, especially when it presents clinically as a primary breast lesion.
