Diagnostic challenges for a case of maxillary carcinoma cuniculatum in the setting of human immunodeficiency virus: a case report.
Review in Oral and maxillofacial surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposeCarcinoma Cuniculatum (CC) is an exceptionally rare variant of squamous cell carcinoma with limited description in the literature. Oral Carcinoma Cuniculatum (OCC) continues to be a diagnostic dilemma as it generally presents as an indolent infection, often undergoing multiple biopsies and debridements prior to definitive diagnosis. This study aims to review the diagnostic challenges, clinical features, histopathology, and management of OCC. We specifically present a unique case of OCC in a patient with human immunodeficiency virus (HIV).
methodsA review of the current literature on OCC was conducted, focusing on diagnostic delays, clinical presentation, histopathologic characteristics, and treatment approaches. Additionally, a case report of a 47-year-old male with OCC is presented, including clinical course, diagnostic workup, and management.
resultsThe patient underwent multiple biopsies and surgical debridements over a 3-year period prior to definitive diagnosis. He was ultimately treated with subtotal maxillectomy and radial forearm free flap reconstruction. Final pathology demonstrated pT4a OCC. His clinical course was further complicated by previously undiagnosed HIV infection. Multidisciplinary tumor board recommendations included bilateral elective neck dissections and adjuvant radiation therapy.
conclusionOCC remains a diagnostic challenge due to its indolent behavior and nonspecific presentation, often resulting in delayed diagnosis and advanced disease at treatment. This case highlights the importance of maintaining clinical suspicion for malignancy in persistent oral lesions and may represent the first reported case of OCC in a patient with HIV, thus raising new questions regarding the potential role of immunosuppression while propagating prior inquiries.
