A rare case of facial dermatofibrosarcoma protuberans and its reconstructive challenges

Reconstructive strategies for dermatofibrosarcomas of the face: role of regenerative dermal templates

BACKGROUND

Dermatofibrosarcomas protuberans is a challenging cutaneous tumor from an oncologic and reconstructive surgical point of view. Involvement of functionally and aesthetically sensitive areas, such as facial units, in young patients accounts for more demanding cases. An updated evaluation of most beneficial excisional/reconstructive strategies in these cases is still lacking.

METHODS

We investigated the potential of regenerative dermal templates in staged postoncologic reconstructive management of a young woman affected by a dermatofibrosarcomas protuberans of the forehead involving the frontal bone.

RESULTS

Final result was optimal in terms of cosmetic and functional recovery, obtaining a pliability, softness, and color similar to surrounding healthy skin.

CONCLUSION

In facial dermatofibrosarcomas protuberans, staged reconstruction with regenerative dermal templates provides a conservative yet safe and effective management, achieving optimal aesthetic outcomes. We suggest its adoption as first-line treatment in facial dermatofibrosarcomas protuberans that cannot be repaired by direct suture and in equivalent benign yet challenging cases.

Half forehead reconstruction with a single rotational scalp flap for dermatofibrosarcoma protuberans treatment

Background

Dermatofibrosarcoma protuberans (DFSP) is a soft tissue neoplasm of intermediate to low-grade malignancy. Although metastasis rarely occurs, DFSP has a locally aggressive behavior with a high recurrence rate. In the head and neck area, resection involving a wide margin of healthy tissue can be difficult because of functional and cosmetic considerations. We describe a novel reconstructive method for half forehead defects with an innovative single local wide scalp flap following excision of DFSP with a 3 cm margin of healthy tissue.

Methods

Two patients underwent wide resection of forehead DFSP and reconstruction with a single rotational scalp flap. The scalp flap blood supply was provided from three main vessels: the superficial temporal artery, occipital artery and posterior auricular artery.

Results

No early or late complications were observed in either patient with no local recurrence after 18 months of follow-up. The donor area could be closed primarily in both cases and the flaps survived completely.

Conclusion

This innovative technique allowed a radical excision of forehead DFSP with sufficient healthy margins, thus potentially decreasing tumor recurrence rate. Reconstruction was achieved avoiding microsurgery, skin expanders and large skin grafts. Moreover, all main reconstructive criteria, such as functional and cosmetic tissue characteristics, were completely fulfilled.
