A Case of Dermatofibrosarcoma Protuberans Arising in a Burn Scar on the Chest Following Electrical Defibrillation.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Dermatofibrosarcoma protuberans (DFSP) is a rare, locally aggressive skin tumor, and its origin from a burn scar is extremely rare. We report a case of a man in his 60s with DFSP that arose within an electrical burn scar sustained from electrical defibrillation for cardiac arrhythmia 20 years prior. The patient presented with a pedunculated tumor and a nearby subcutaneous nodule on his anterior chest. The diagnosis of DFSP was confirmed by histopathological examination, which revealed a characteristic storiform proliferation of spindle cells, and by immunohistochemistry showing positivity for CD34 and negative for epithelial membrane antigen (EMA), S-100, and alpha-smooth muscle actin (α-SMA). Wide local excision and reconstruction with a latissimus dorsi myocutaneous flap and a split-thickness skin graft were performed. The patient has shown no evidence of recurrence for two years postoperatively. As demonstrated by the subcutaneous nodule in this case, DFSP can be clinically difficult to diagnose. Therefore, careful long-term follow-up and consideration of a skin biopsy, as needed, are crucial for such burn scars.
