Testicular mass frozen section examination: Pathological insights and diagnostic accuracy.
Article in Histopathology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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 AND
objectivesTesticular frozen section examination on excisional biopsy (FSEB) is an underused pathological and surgical approach, considering the increasing number of small benign testicular lesions found on radical orchidectomy specimens. This study aims to determine the diagnostic accuracy of FSEB and to provide a pathological summary of the most frequent diagnoses and pitfalls.
methodsWe report the pathological findings and definitive outcome of 135 FSEB for small testicular masses performed between 2005 and 2024 in a single institute.
resultsThe median tumour size was 0.9 cm (Interquartile Range [IQR] 0.5-1.3 cm). The most common FSEB diagnoses were Leydig cell hyperplasia/tumour (n = 37; 28%) and seminoma (n = 36; 27%). On FSEB, benign diagnoses represented 58% of cases which allowed us to avoid 81 unnecessary radical orchidectomies. The sensitivity and specificity of FSEB for malignancy were 100% and 96.3%, respectively. Excluding three indeterminate cases on FSEB, the concordance rate was 97.7% (129/132). On definitive assessment, the majority of cases were benign (84/135, 62%) and 51 (38%) cases were malignant. The three indeterminate cases were ultimately confirmed as benign. There were three false-positive diagnoses of (favoured) malignancy and no false negatives.
conclusionsFSEB is accurate for patient management of small testicular lesions, allowing us to save young men from unnecessary radical orchidectomy. We provide an in-depth overview of the most prevalent pathological diagnoses encountered.
