Surgical management of gingival plasma cell granuloma with histopathological and immunohistochemical confirmation through CD138 and kappa/lambda polyclonally: a case report.
Article in Journal of surgical case reports, 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
Plasma cell granuloma (PCG) is a benign inflammatory lesion of reactive origin that is rarely found in the oral cavity. Accurate recognition is essential to differentiate it from malignant lesions and avoid overtreatment or unnecessary radical resections. We present the case of a 26-year-old female with no systemic history who presented with an asymptomatic, firm, erythematous gingival mass in the right upper posterior sextant. The lesion was associated with subgingival dental calculus and a deep carious lesion involving the first premolar and first molar. Treatment included complete surgical excision, extraction of both teeth, and bone curettage. Histopathological examination confirmed PCG, while immunohistochemistry showed CD138 positivity (70%) and polyclonal Kappa/Lambda expression, excluding monoclonal neoplastic restriction. At the 2-month follow-up, healing was satisfactory without recurrence. Histopathological and immunohistochemical evaluation provides a definitive diagnosis, and conservative surgical management is curative.
