A novel parotid carcinoma with a prominent ghost cell population: a masquerading tumor or "salivary ghost cell carcinoma"?
Article in Medical molecular morphology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Ghost cell is one of several unique cellular morphologies associated with aberrant keratinization. We encountered a novel parotid tumor containing numerous ghost cells and herein describe its histological features and discuss diagnostic problems. The patient was a 90-year-old Japanese male, who complained of swelling of the left parotid area for four months. Positron emission tomography indicated no cervical lymph node metastasis or distant metastasis. The tumor was successfully resected with no signs of recurrence or metastasis for six months after surgery. Histologically, the tumor was mainly composed of squamous cells forming irregularly shaped nests with a mixture of pleomorphic giant or multinucleated cells and bland basaloid cell. Keratinized areas were occupied by a prominent ghost cell population. Immunohistochemically, CK5/6 and CK19 were widely positive as well as AE1/AE3, p40 and p63. Nuclear expression of β-catenin was also observed. The present case can be regarded as a particular form of squamous cell carcinoma and is believed to contain a large number of ghost cells resulting from an unclear mechanism. However, it seems difficult to consider such tumors as a clinicopathologically independent entity at present. Applying a term such as "salivary ghost cell carcinoma" would be premature.
