Wichtige Änderungen in der WHO-Klassifikation der Hodentumoren 2022

The 5th Edition of the "WHO Classification of Tumours: Urinary and Male Genital Tumours" introduces several significant updates to the classification of testicular tumours. These updates include revised terminology for special germ cell tumour subtypes (neuroectodermal and neuroendocrine tumours) of the testis. Additionally, the signet-ring stromal tumour and myoid gonadal stromal tumour have been introduced as distinct entities within the sex-cord stromal tumours. Moreover, new combined sections have been created for lymphatic neoplasms and soft tissue tumours of the urinary and male genital tract.
