Sonographic Demonstration of Dermatofibrosarcoma Protuberans: An Uncommon Soft Tissue Neoplasm

This case study presents the sonographic features of recurrent dermatofibrosarcoma protuberans, an uncommon soft tissue neoplasm. The original primary tumor presented five years earlier and was surgically excised. The current presentation demonstrates sonographic evaluation of several superficial left lower quadrant masses suspicious for tumor recurrence. This was confirmed by core needle biopsy and was followed by wide surgical excision. No evidence of metastasis was found, and no chemo or radiotherapy was offered.
