Management of two rare cases of dermatofibrosarcoma protuberans arising in the parotid region

Dermatofibrosarcoma protuberans (DFSP) is a rare cutaneous tumour, accounting for less than 1% of malignant tumours of the head and neck region. This tumour rarely presents metastatic disease, but has a high recurrence rate. Therefore, wide surgical excision with microscopically free margins is the therapeutic gold standard. Only five cases are described in literature of this tumour arising in the parotid region, a site that presents challenges both in achieving a wide demolition and in reconstructing the resulting defect. Here we describe two cases of DFSP arising in the parotid region that were treated surgically, achieving microscopically free margins. Reconstruction of the vast skin defect was achieved by means of a supraclavicular artery island flap, with good functional and aesthetic results.
