Type II TTE is accompanied by persistent M\u00fcllerian duct syndrome, where the M\u00fcllerian structures persist for various reasons. Here, we present a case of an adult in his early 30s, who presented with a right testicular swelling and was diagnosed as type II TTE and testicular mixed germ cell tumour after surgery. We could find only 13 similar cases of TTE and testicular tumours in the literature. Our case highlights the importance of clinical acumen with detailed history, meticulous clinical examination, radiological investigations and a detailed pathological examination while dealing with such sporadic presentations.<\/jats:p>","DOI":"10.1136\/bcr-2024-260905","type":"journal-article","created":{"date-parts":[[2024,5,28]],"date-time":"2024-05-28T22:35:19Z","timestamp":1716935719000},"page":"e260905","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Diagnostic
