Dermatofibrosarcoma protuberans of scalp : a case report

Area of Science:

• Oncology
• Surgical Oncology
• Dermatopathology

Background:

• Dermatofibrosarcoma protuberans (DFSP) is a rare, locally aggressive skin cancer.
• Scalp involvement presents unique surgical challenges due to proximity to vital structures and bone.
• Recurrence necessitates aggressive management strategies.

Observation:

• A case of recurrent dermatofibrosarcoma protuberans on the scalp with underlying bone erosion is presented.
• The patient underwent revision surgery following initial recurrence.
• A wide safety margin of 3 cm was excised.

Findings:

• Complete tumor excision with a 3 cm safety margin was achieved.
• The resulting skin and soft tissue deficit was successfully reconstructed using a transposition flap.
• Histopathological confirmation of tumor-free margins was obtained.

Implications:

• This case highlights the importance of wide surgical margins for DFSP, especially in recurrent or bone-involving cases.
• Transposition flaps are a viable option for reconstructing scalp defects after oncologic resection.
• Optimal management of recurrent scalp DFSP requires a multidisciplinary approach.
