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

Introduction: Cutaneous squamous cell carcinoma (cSCC) is a common malignant skin cancer arising from epidermal squamous cells, typically developing on chronically sun-exposed skin. The clinical diagnosis of cSCC is usually rather straightforward, although one should be aware of rare and atypical subtypes. Case Presentation: An 83-year-old woman, hospitalized for the workup of auricular fibrillation, presented a 10 × 5.5 cm, indolent, indurated, slightly purulent, tumoral mass on her left hand, that progressively increased in volume since around 2 years. There was no functional failure and no locoregional adenopathies. The first punch biopsy favored a keratoacanthoma. The culture of the purulent discharge revealed no microorganisms. MRI did not reveal any deep soft tissue or bone invasion. Excisional surgery was performed under local anesthesia. Histology revealed a well-differentiated cSCC-like exophytic tumor with an endophytic architecture composed of tortuous, keratin-filled, interconnected crypts, highly suggestive of cSCC of the cuniculatum type. Conclusion: Carcinoma cuniculatum is an exceptional subtype of cSCC, with an indolent clinical evolution and a well-differentiated histological presentation. Dermatologists and plastic surgeons should be aware of this rare type of cSCC that is to be differentiated from verrucous carcinoma, keratoacanthoma, cSCC and pseudo-epitheliomatous hyperplasia. Aggressive therapy must be avoided as deep invasion is exceptional, the growth is highly indolent and locoregional or systemic metastatic lesions are nearly never observed. Surgical excision is the cornerstone of treatment.
