title: [Pulmonary metastasis of fibrosarcomatous variant of dermatofibrosarcoma protuberans: case report and review of literature].
abstract: A 63-year-old man had undergone excision of a growing mass with a wide margin in the left supraclavicular fossa. A diagnosis of fibrosarcomatous variant of dermatofibrosarcoma protuberans (DFSP-FS) was made. Three years later, an abnormal chest shadow was detected on a medical checkup. Chest computed tomography showed a heterogeneously-enhanced 2-cm coin lesion with a distinct border in the right lower lobe and a 3-mm nodule in the left lower lobe. Transbronchial lung biopsy specimens from the right lung revealed a DFSP pattern. We then performed right basal segmentectomy and partial resection of the left lower lobe. DFSP is a relatively rare skin tumor that is considered to be intermediate malignancy. It frequently recurs locally but rarely has systemic metastasis. However, DFSP-FS, a subtype of DFSP, has an increased likelihood of systemic metastasis. The lung is the most common site of metastasis of DFSP-FS. DFSP-FS sometimes recurs even a long time after excision. Therefore, long-term follow-up, including chest X-ray and CT are important in DFSP-FS patients.
