A patient with testicular pseudolymphoma - a rare condition mimicking malignancy: a case report

Three months following a right sided acute epididymitis a 62 year old patient presented with a painless right testicular swelling. Physical examination, scrotal ultrasound and operative exploration suggested malignancy. However, after inguinal orchiectomy a benign pseudolymphoma of the testis was revealed by pathological examination. A pseudolymphoma is a rare benign lesion which can only be distinguished from a malignant lymphoma by immuno-histochemistry and molecular-genetical investigation techniques.
