He is currently sexually active with two female partners and uses condoms inconsistently. He immigrated to the US from Argentina 2 years ago. His immunization records are unavailable. He has smoked one pack of cigarettes daily for the last 5 years. He is 170 cm 5 ft 7 in tall and weighs 70 kg 154 lb; BMI is 24.2 kgm2. He appears healthy and well nourished. His temperature is 37C 98.6F, pulse is 72min, and blood pressure is 12575 mm Hg. The lungs are clear to auscultation. Cardiac examination shows no abnormalities. The abdomen is soft with dull lower abdominal discomfort. Testicular examination shows a solid mass in the right testis that is firm and nontender. A light held behind the scrotum does not shine through. The mass is not reduced when the patient is in a supine position. The remainder of the physical examination shows no abnormalities. Which of the following is the most likely diagnosis in this patient?? A: Orchitis, B: Hydrocele testis, C: Scrotal hernia, D: Testicular torsion, E: Testicular tumor,  <response>: This is a clinical case scenario about a 25-year-old man with right-sided painless scrotal swelling. The key findings are:- Right-sided painless scrotal swelling noticed yesterday - Sexually active with multiple partners, inconsistent condom use- Immigrated from Argentina 2 years ago, immunization records unavailable- Smokes 1 pack per day for 5 years- Physical exam shows solid mass in right testis that is firm, nontender, does not transilluminate, and is not reduced when supineBased on the sudden onset and physical exam findings, the most likely diagnosis is a testicular tumor. Orchitis would cause pain and swelling but is unlikely with no pain. Hydrocele testis causes a fluid collection that transilluminates. Scrotal hernia and testicular torsion are unlikely given the lack of pain and lack of reducibility when supine. Therefore, the most likely diagnosis is testicular tumor.E: Testicular tumor
