Prevalence of Testicular and Paratesticular Tumours: A 10-year Retrospective Study

Abstract

Introduction: Testicular Germ Cell Tumours (TGCTs) seminomas and non-seminomas constitute more than 90% of all type II germ cell tumours and account for only 1% of all the cancers in male worldwide. There is high incidence of testicular tumours in the western world compared to Asian and African countries. TGCTs occur at an early age compared to malignant tumours of other organs. Nonseminomatous germ cell tumours should be distinguished from seminomatous tumours because, the later have higher cure rate. Mesenchymal tumours are more common in paratesticular area. Aim: To know the prevalence of testicular and paratesticular tumours. Materials and Methods: This was a retrospective descriptional study done in Department of Pathology, NRI Medical College, Chinakakani, Guntur, Andhra Pradesh, India, over a period of 10 years from January 2010 to December 2019. The data such as age and histopathological diagnosis of testicular and paratesticular tumours were archived from the medical records and from histopathology annals. The results were analysed and presented in the form of percentages. Results: A total of 26 testicular and paratesticular tumours were identified over 10 years of study period. Out of these cases testicular seminomas were the most common germ cell tumours. The mean age was 35.5 years and 32.1 years for seminomas and for non-seminomatous tumours, respectively. There were two cases of paratesticular rhabdomyosarcomas in paediatric age group and one case of adenomatoid tumour. Conclusion: The most common testicular tumour in the study was germ cell tumour. Among testicular tumours, seminomas were the most common tumours and among paratesticular tumours, mesenchymal tumours were more common.
