Orbital granular cell tumor involving the superior rectus muscle: a case report.
Article in Frontiers in oncology, 2024. 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
Objective: The aim of this case report is to assess the clinicopathological characteristics and differential diagnosis of orbital granular cell tumor (GCT). Methods: Clinical and imaging data of a rare case of orbital GCT involving the superior rectus muscle were collected. Its clinical characteristics, imaging, and histopathological features were observed. Results: A 36-year-old female patient presented with a 2-year history of left eye proptosis. Magnetic resonance imaging (MRI) enhancement suggested a space-occupying lesion in the left superior rectus muscle region. On T1-weighted and T2-weighted MRI, the tumor was isointense to gray matter and significantly enhanced on the enhanced scan. Microscopic examination revealed that most tumor cells exhibited diffuse growth with unclear boundaries, and some cells were arranged in small nests. The tumor cells were large, with abundant, coarse eosinophilic granules in the cytoplasm. Occasional cells contained larger round eosinophilic droplets in the cytoplasm. Focal areas showed foamy cells, small and central round or oval nuclei with occasional nuclear enlargement and mild atypia, inconspicuous nucleoli, rare mitoses, and low proliferative activity. Immunohistochemistry results were Vimentin (+), S-100 (+), CD68 (+), Ki67 (2%+), Inhibin-a (-), CK (-), SMA (-), and Desmin (-). The pathological examination of a specimen harvested from the mass corresponded to a GCT. Conclusion: Orbital GCT is rare and should be considered in the differential diagnosis of orbital tumors. It is essential to distinguish it from thyroid-associated ophthalmopathy, inflammatory pseudotumor, and myohemangioma. Definitive diagnosis requires a comprehensive analysis of clinical, histopathological, and immunohistochemical findings. Surgical excision is the primary treatment for orbital GCTs. For patients with incomplete tumor resection, close follow-up is necessary. Proton beam radiation therapy can be considered to prevent recurrence or metastasis if needed.
