Keloid-like Pilomatricoma of the Auricle: A Case Report and Review of Literature.
Article in Case reports in dermatology. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Pilomatricoma is a rare benign skin adnexal tumor arising from hair matrix cells. It usually manifests as a firm-to-hard, well-circumscribed, nontender nodule often mistaken as a dermoid cyst. However, its clinical presentation has been reported to mimic keloid. In addition, although it occurs most frequently in the head and neck area, pilomatricoma is rarely reported on the auricle. Herein, we reported a case of pilomatricoma occurring on the posterior part of a 9-year-old girl's auricle. Unlike classic pilomatricoma, the tumor closely resembled a keloid. Nevertheless, histological examination following excision of the tumor revealed a dermal tumor arranged in solid nests consisting of basaloid and ghost cells along with foreign body reaction, calcification, and ossification, confirming the diagnosis of pilomatricoma. The rarity, atypical clinical presentation, and unique location of this tumor contributed to the misdiagnosis of this case. Therefore, we reviewed previous cases of pilomatricoma of the auricle reported in the literature to provide a comprehensive understanding of this rare entity.
