Case Two

Overview

Clinical history: This 23-year-old gentleman was found to have a palpable right testicular mass picked up by his family doctor. Ultrasound at that time was able to identify a hyperechoic solid nodule in the lower pole the right testis. Further workup including a chest x-ray and CT of the abdomen did not show any metastatic disease. Tumour markers including LDH, beta-hCG and AFP were normal. On exam, palpation of the right testis identified a mildly tender mass in the lower pole of the right testis that was quite firm in nature and adherent to the testis itself. The patient underwent orchiectomy.
