[A case of granulomatous orchitis].

ABSTRACT

A 66-year-old man came to us with a chief complaint of painful right scrotal swelling. The right testis was enlarged on the ultrasound gray scale, but the inside was homogeneous. A power Doppler ultrasound showed slightly increased vascular flow in the periphery of the right testis. As the soluble IL-2 receptor was 527 U/ml (normal 220-530 U/ml), we considered malignant lymphoma and performed high orchiectomy. On pathological examination, the tumor was diagnosed as granulomatous orchitis. To our knowledge, this is the 21st case in Japan.
