Parosteal lipoma of the mandible: a case report of an asymptomatic, non-ossifying variant.

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
Parosteal lipoma is a rare benign neoplasm arising in intimate association with the periosteum. Involvement of the mandible is exceptionally rare. We present the case of a 75-year-old man presenting with a 1-year history of a painless, fixed mass on the left chin. Unlike previous reports of mandibular parosteal lipomas which often feature ossification or neurologic symptoms, this patient was asymptomatic, and imaging revealed a non-ossifying, homogeneous fat-density mass. The tumor was completely excised via an extraoral approach. Surgically, the mass was firmly adherent to the periosteum, requiring meticulous dissection at the subperiosteal level to ensure complete removal. Histopathology confirmed a simple lipoma. This case highlights a critical diagnostic and surgical lesson for plastic surgeons: a fixed mandibular mass, even if asymptomatic and radiologically benign, suggests potential periosteal adherence. Therefore, surgical planning must prioritize deep, periosteal-level dissection rather than simple enucleation to prevent recurrence.
