1 · What the graph read from it

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.

2 · The registry

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

Trichilemmal carcinoma (TC), a rare malignancy originating from hair follicle cells, typically affects sun-exposed skin in older individuals and necessitates differential diagnosis from other skin carcinomas. Here, we present one case of trichilemmal carcinoma in a 92-year-old female, admitted to our hospital with a large exophytic red tumor on her right lower leg. Notably, the patient had a history of long-standing hypothyroidism and hypertension, indicating that she was unable to tolerate extensive excision. Histopathology showed outer root sheath hyperplasia with clear cell differentiation and keratinization, alongside increased atypical cells. Immunohistochemistry revealed CK7 and EMA positivity, confirming follicular origin, while negative CK10, CK18, CEA, CK20, and GCDFP-15 excluded other follicular tumors. A high Ki-67 (80%) indicated high proliferative activity, supporting the TC diagnosis. Treatment involved managing her underlying conditions, followed by ALA-PDT and surgical excision for the carcinoma. This case illustrates the challenges in managing trichilemmal carcinoma in elderly patients with multiple comorbidities, emphasizing the importance of a comprehensive approach to treatment.
