Rapidly Enlarging Forearm Nodule Representing Keratoacanthoma-Type Crateriform Squamous Cell Carcinoma in a 54-Year-Old Man: A Case Report.

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
Keratoacanthoma-type crateriform squamous cell carcinoma is an uncommon cutaneous neoplasm that clinically mimics benign keratoacanthoma yet carries malignant potential. This case report describes a 54-year-old Caucasian man with occupational sun exposure and no past medical or significant family history, who developed a rapidly enlarging, dome-shaped nodule with a central keratin plug on his left forearm over six weeks. The lesion was removed via full-thickness fusiform excision with 4 mm margins and closed primarily; histopathology confirmed a crateriform squamous cell carcinoma with clear margins. The surgical site healed uneventfully, and the patient remains disease-free at the three-month follow-up. This report highlights the key clinical and histopathological features that distinguish this variant, reviews optimal surgical management and the need for ongoing surveillance, and aims to enrich the limited literature on keratoacanthoma-type crateriform squamous cell carcinoma to aid clinicians in prompt recognition and treatment.
