ABSTRACT
BACKGROUND:
Relatively little is known about the true aggressive potential of pleomorphic dermal sarcoma (PDS) or optimal management strategies.OBJECTIVE:
To describe the outcomes of 16 cases of PDS treated at our hospital (14 with modified Mohs micrographic surgery [M-MMS] and two with conventional surgery) and establish an adequate plan for management. MATERIALS &METHODS:
We reviewed 16 PDS cases treated at our hospital between October 2007 and June 2019 and compared our results with the available evidence.RESULTS:
In total, 69% of cases had recurred after initial conventional surgery, M-MMS led to local disease control in 83% of cases, and 19% of patients developed metastasis. Combining all published PDS cases with ours, we calculated an overall metastasis rate of 12%, and an overall recurrence rate of 35% after conventional surgery and 17% after M-MMS.CONCLUSION:
PDS is more aggressive than previously estimated, with an overall metastatic rate of 12%. Despite high recurrence rates with previous conventional surgery (69%), M-MMS achieved a good rate of local disease control (83%). Given the potential aggressivity of PDS and the importance of clear surgical margins, M-MMS appears to be more adequate than conventional excision. Staging studies and close monitoring are warranted in PDS patients, for which we propose a management algorithm.Palabras clave
