A 20-year-old male finds a mass in his scrotum. The first step in evaluating this mass is
**Core Concept**
The evaluation of a scrotal mass involves distinguishing between testicular and extratesticular causes, which requires a systematic approach to identify the underlying pathology. This involves assessing the location, size, and characteristics of the mass, as well as the patient's symptoms and medical history.
**Why the Correct Answer is Right**
The first step in evaluating a scrotal mass is to inspect the scrotum and perform a scrotal exam. This involves examining the location, size, consistency, and mobility of the mass. The patient should be asked to lie supine and then stand to see if the mass moves with the testis (indicative of a epididymal or spermatic cord origin) or remains stationary (suggestive of a testicular origin). Additionally, the patient should be examined for any signs of inflammation, such as redness, swelling, or tenderness.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because it does not involve a thorough physical examination of the scrotum and surrounding areas.
* **Option B:** This option is incorrect because it does not take into account the need to distinguish between testicular and extratesticular causes of the mass.
* **Option C:** This option is incorrect because it involves immediate imaging without a thorough physical examination.
**Clinical Pearl / High-Yield Fact**
A key point to remember when evaluating a scrotal mass is the "5 Ds": Dullness (indicative of a hydrocele), Direction (does the mass move with the testis or remain stationary), Discomfort (does the mass cause pain), Dimpling (does the scrotal skin appear dimpled), and Delayed onset (does the mass develop over time).
**Correct Answer: C. Ultrasound.**
