Malignant Peripheral Nerve Sheath Tumor Arising After Superficial Neurofibroma Excision: A Rare Sporadic Case in a Patient Without Neurofibromatosis Type 1.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Malignant peripheral nerve sheath tumors (MPNSTs) are rare sarcomas that often arise in the setting of neurofibromatosis type 1 (NF1) or prior radiation exposure. Sporadic MPNSTs are significantly less common and rarely originate from superficial cutaneous neurofibromas. We present a unique case of MPNST arising at the site of a previously excised superficial neurofibroma in a patient without NF1. This case highlights the diagnostic complexity of MPNSTs arising in superficial cutaneous neurofibromas, requiring timely recognition given the tumor's aggressive behavior and poor prognosis. While degenerative changes within neurofibromas are typically benign, they may obscure early malignant transformation, complicating diagnosis. These findings underscore the need for continued surveillance of recurrent neurofibromas and further research into MPNST pathogenesis in non-NF1 populations.
