Recurrent Dermatofibrosarcoma Protuberance: A Case Report

Abstract

Dermatofibrosarcoma protuberance represents less than 0.1% of all tumors, treatment of which requires wide local excision (≥5cm) but recurrence is not rare. Here we present a 32-year male presented with a swelling of 15 x 6cm over the left lumbar region for which he underwent excision three years ago, the histopathological examination of the swelling, showed a malignant mesenchymal tumor and Immunohistochemistry features were suggestive of Dermatofibrosarcoma protuberance. After three years of interval, he again presented with complaints of swelling in the previously operated site for nine months and underwent excision of the mass with Split Thickness Skin Graft. Although the tumor was confined to the skin and subcutaneous tissue in the present case, the patient didn’t undergo any adjuvant radiotherapy to avoid a possible relapse that would infiltrate deeper structures for the first time. Being a recurrent tumor, long-term follow-up is strongly recommended.

“…Even after years of treatment, patients can present with lesions suggestive of the disease that need surgery along with reconstruction flaps. 7 These tumors have locally invasive potential and need recurrent surveillance and follow‐up visits along with proper counseling. 8 As DFSP is rare, given the limitation of available diagnostic modalities such as immunohistochemistry (IHC), in a resource‐poor setting, diagnosis can be confusing.…”

“…Recurrence is a common rule in DFSP, and most of the tumors exhibit recurrence that warrant wide excision with margin. Even after years of treatment, patients can present with lesions suggestive of the disease that need surgery along with reconstruction flaps 7 . These tumors have locally invasive potential and need recurrent surveillance and follow‐up visits along with proper counseling 8 .…”
