Dermatofibrosarcoma protuberans (DFSP) is a spindle cell malignancy that has a high local recurrence rate after excision with minimal or no immediate tissue margin assessment. DFSP is exceedingly rare on the palms and soles.
To report a case of a locally aggressive DFSP on the sole excised using Mohs micrographic surgery.
Case report and review of the literature.
Mohs micrographic surgery unmasked tumor infiltration that extended around plantar aponeurosis and into underlying plantar muscle fascia.
Mohs micrographic surgery should be considered the treatment of choice for DFSP, especially in acral locations. This technique allows the surgeon to trace out deep tumor extensions that may wrap around underlying tendon, a finding that may not be appreciated clinically.
隆突性皮肤纤维肉瘤（DFSP）是一种梭形细胞恶性肿瘤，在切除后局部复发率高，且很少或根本没有进行即时组织切缘评估。DFSP在手掌和脚底极为罕见。
报告一例采用莫氏显微外科手术切除的脚底局部侵袭性DFSP病例。
病例报告及文献复习。
莫氏显微外科手术显示肿瘤浸润延伸至足底腱膜周围并深入至下方的足底肌筋膜。
对于DFSP，尤其是在肢端部位，应考虑将莫氏显微外科手术作为首选治疗方法。该技术使外科医生能够追踪深部肿瘤的延伸情况，这些延伸可能会包裹下方的肌腱，而这一发现临床上可能无法察觉。
