System describing surgical field extension associated with flap reconstruction after resection of a superficial malignant soft tissue tumor

Figure 4 Myxofibrosarcoma at the buttock reconstructed by a propeller flap (pedicled flap, CdDd). A: A 46-year-old male with a myxofibrosarcoma at the buttock. Magnetic resonance imaging revealed that the tumor showed heterogenous low-to-high signal intensity on the T2-weighted image. Before (A-I) and after (A-II) chemotherapy of doxorubicin and ifosfamide, the tumor size was reduced; B: The resection of the tumor was designed (B-I) and performed (B-II); C and E: A propeller flap from the thigh was designed (C-I) and the pedicle was preserved (C-II) and performed. The CD-grade was CdDd (pedicled flap, CdDd).
