Résumé
Dermatofibrosarcoma protuberans (DFSP) is a rare, locally infiltrating, rarely metastasizing, soft tissue tumour. Due to its indistinct margins, local aggressive behaviour and high recurrence rate, the surgical approach is complex. Micrographic surgery and variants of this technique, e.g. Tubingen torte technique (TTT), should be considered as first-line treatment. To confirm that TTT is a safe and tissue-sparing technique, relative to theoretical wide local excision (WLE), for the same lesions, as recommended by the guidelines in the literature. Seventeen patients with histologically confirmed DFSP, treated with TTT between September 2014 and February 2019, were retrospectively analysed. For each patient, the final TTT excision area was calculated and compared with the theoretical equivalent area based on WLE. The difference in area was calculated and presented as percentage difference of preserved healthy skin based on the two approaches. In our patients, the mean preoperative lesion size was 4.55 ± 5.34 cm In our experience, TTT remains a safe, effective and tissue-sparing treatment for DFSP patients, especially when it is essential to spare tissue and in challenging locations.

BACKGROUND
BACKGROUND
Dermatofibrosarcoma protuberans (DFSP) is a rare, locally infiltrating, rarely metastasizing, soft tissue tumour. Due to its indistinct margins, local aggressive behaviour and high recurrence rate, the surgical approach is complex. Micrographic surgery and variants of this technique, e.g. Tubingen torte technique (TTT), should be considered as first-line treatment.
OBJECTIVES
OBJECTIVE
To confirm that TTT is a safe and tissue-sparing technique, relative to theoretical wide local excision (WLE), for the same lesions, as recommended by the guidelines in the literature.
MATERIALS AND METHODS
METHODS
Seventeen patients with histologically confirmed DFSP, treated with TTT between September 2014 and February 2019, were retrospectively analysed. For each patient, the final TTT excision area was calculated and compared with the theoretical equivalent area based on WLE. The difference in area was calculated and presented as percentage difference of preserved healthy skin based on the two approaches.
RESULTS
RESULTS
In our patients, the mean preoperative lesion size was 4.55 ± 5.34 cm
CONCLUSION
CONCLUSIONS
In our experience, TTT remains a safe, effective and tissue-sparing treatment for DFSP patients, especially when it is essential to spare tissue and in challenging locations.
