[Involvement of an extralymphatic organ in Hodgkin's lymphoma]

This case report describes the rare entity of Hodgkin's lymphoma manifesting itself in an extralymphatic organ. To rule out a second malignancy, we performed a transurethral resection of the urinary bladder (TUR-B) in our urology department, confirming the histological findings. After that, the patient received oncological treatment based on the current guidelines.
