Unusual Location of a Cutaneous Granular Cell Tumor: A Case Report and Review of the Literature.
Article in Cureus, 2026. 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
Granular cell tumor (GCT), or Abrikossoff's tumor, is an uncommon neurogenic neoplasm originating from Schwann cells. While predominantly benign and frequently found in the head and neck, its clinical and radiological presentation can mimic more aggressive soft tissue sarcomas. We report the case of a 65-year-old female patient presenting with a firm, slow-growing mass in the right submammary fold. The biopsy revealed polygonal cells with granular, eosinophilic cytoplasm. Immunohistochemistry (IHC) showed diffuse S100 protein positivity and CD34 negativity, confirming a cutaneous GCT. The tumor exhibited infiltrative growth patterns with involved margins, perineural tracking and vascular invasion that defined an atypical tumor according to Fanburg-Smith criteria. A wide excision with 1 cm margins was made to achieve a complete resection with uneventful follow up. GCT is often known as a "great mimicker" due to its ability to simulate malignancies. Given the high local recurrence rate (20-40% for margin-positive or infiltrative lesions), GCTs necessitate wide-margin excision.
