Keratinizing Penile Squamous Cell Carcinoma Arising from Chronic Balanoposthitis in an Uncircumcised Diabetic Man: A Case Report from a Rural Tertiary Hospital in Uganda.
Article in International medical case reports journal, 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
Background: Penile squamous cell carcinoma (SCC) primarily develops through two distinct etiopathogenic routes: human papillomavirus (HPV)-mediated and non-viral, chronic inflammation-driven pathways. In low-resource settings, long-standing phimosis and recurrent balanoposthitis present significant public health challenges that accelerate tissue transformation. Case Presentation: We report a case of an uncircumcised 75-year-old African man presenting to a tertiary facility in Southwestern Uganda with a 2-year history of a progressive, painful, exophytic penile mass associated with chronic balanoposthitis and a 7-year history of Type 2 Diabetes Mellitus. Clinical examination revealed a 4.0 cm × 5.0 cm ulcerated, necrotic tumor involving the glans penis and distal shaft, along with bilateral 1.5 cm palpable inguinal lymph nodes. Due to resource constraints at our center, molecular screening (p16 immunohistochemistry and HPV DNA PCR) and staging node biopsies were unavailable. Histopathological examination of the partial penectomy specimen confirmed a well-differentiated, keratinizing squamous cell carcinoma (pT2 cN0 M0). The patient experienced an uneventful postoperative recovery and was transitioned to a structured clinical surveillance program. Discussion: This case highlights the role of chronic balanoposthitis, diabetes mellitus, and poor foreskin ventilation in promoting a sustained inflammatory microenvironment that may predispose to malignant transformation of penile epithelium. It underscores the diagnostic challenge posed by inflammatory penile lesions that mimic benign disease and the consequences of delayed medical evaluation. Conclusion: This case provides a descriptive illustration of penile carcinoma emerging in a background of chronic inflammation, highlighting the clinical realities of managing advanced disease in a resource-limited environment. It underscores the critical need for localized screening, early surgical intervention for phimosis, and improved access to molecular diagnostics in sub-Saharan Africa.
