Primary Malignant Melanoma of the Sphenoid Sinus as a Crucial Differential Diagnosis of Skull Base Tumors: A Case Report.
Article in NMC case report journal, 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
A 79-year-old man presented with progressive ptosis, diplopia, and headaches, which led to the diagnosis of a rare primary malignant melanoma of the sphenoid sinus. Imaging revealed extensive bone destruction and aggressive tumor behavior. The rarity of primary malignant melanoma in the sphenoid sinus complicates early detection. Despite undergoing surgical decompression, immunotherapy, and radiation therapy, the tumor rapidly recurred, necessitating supportive care. This case highlights the need for neurosurgeons to include primary malignant melanoma in the differential diagnosis of skull base tumors, particularly in the sphenoid sinus, due to its potential for aggressive local invasion and significant impact on critical neurovascular structures. Early recognition and intervention are crucial for managing this rare and aggressive malignancy effectively.
