INTRODUCTION: Our goal was to evaluate benign and malignant lesions and testicular intraepithelial neoplasia (TIN) in the neighbouring normal-appearing testis tissue in men who underwent radical orchiectomy for testicular mass with a pathologic tumour size of ≤3cm. METHODS: In this retrospective, multicentre study, data of 252 patients from 11 different institutions were included. Patients were divided into three groups based on tumour size: Group 1 (0-1 cm; n=35), Group 2 (1.1-2cm; n=99), and Group 3 (2.1-3 cm; n=118). Benign lesions and TIN were sought in the neighbouring testicular tissue and compared between groups. RESULTS: Mean patient age was 32.3 years. Benign lesions were reported in 54.3%, 33.3%, and 14.4% of Groups 1, 2, and 3, respectively (p<0.05 between groups). TIN was detected in 20%, 42.4%, and 41.5% of Groups 1, 2, and 3, respectively (p<0.05 for Group 1 vs. Groups 2 and 3; p>0.05 for Groups 2 vs. 3). Multifocality was detected in 8.6%, 4%, and 0% of Groups 1, 2, and 3, respectively (p<0.05 for both Group 1 vs. Group 3 and for Group 2 vs. Group 3; p>0.05 for Group 1 vs. Group 2). A tumour cutoff size of 1.5 cm was found to be significant for detecting benign tumour. TIN and multifocality rates were similar in patients with a tumour size of ≤1.5 vs. >1.5 cm (p>0.05). CONCLUSIONS: Benign lesions and TIN in the neighbouring testis were significantly decreased and multifocality was increased in patients with a tumour mass size of ≤1 cm. Testis-sparing surgery should be performed with caution and a safety rim of normal tissue should also be excised.
