Application of volume displacement technique in the operation of breast dermatofibrosarcoma protuberans: A case...

Dermatofibrosarcoma protuberans (DFSP) of the breast is exceedingly rare. Surgical management requires achieving negative margins while preserving breast aesthetics, which presents a significant challenge. This case demonstrates the use of the volume displacement technique as a reconstructive approach to balance oncologic safety with cosmetic outcomes.

A 41-year-old woman was referred for evaluation of a palpable mass in the left breast, identified during routine physical examination. She reported no pain or systemic symptoms.

Imaging revealed a subcutaneous mass with mixed echogenicity and abundant vascularity. Core biopsy suggested a spindle cell tumor. Histopathology and immunohistochemistry confirmed the diagnosis of DFSP (CD34 positive, Vimentin positive, negative for other markers).

The patient underwent wide local excision with negative margins under general anesthesia, followed by immediate reconstruction using the volume displacement technique to preserve breast contour.

Postoperative pathology confirmed complete tumor removal with negative margins. The patient recovered without complications, and no recurrence was observed during follow-up. Cosmetic results were satisfactory.

DFSP of the breast is rare, and achieving oncologic safety without compromising aesthetics is challenging. The volume displacement technique offers a valuable reconstructive option, allowing wide excision while maintaining breast contour. This approach may serve as a useful strategy in similar cases, though further studies are needed to confirm its broader applicability and long-term outcomes.
