A 30 years old male came to OPD with palpable mass in relation to testis. On examination, the testis was enlarged and the mass was hard. What is the next best step?
**Core Concept**
The underlying principle being tested is the initial assessment and management of a testicular mass, which could be indicative of **testicular cancer**. A hard, palpable mass in relation to the testis warrants further investigation due to the potential for malignancy.
**Why the Correct Answer is Right**
Although the options are missing, in a scenario like this, the next best step typically involves diagnostic imaging, specifically **ultrasound**, to characterize the mass and assess for any features concerning for cancer, such as heterogeneity, irregular margins, or increased vascularity. This step is crucial for guiding further management, which may include surgical exploration or biopsy.
**Why Each Wrong Option is Incorrect**
**Option A:** Would be incorrect if it suggested watching and waiting, as testicular masses require prompt evaluation.
**Option B:** Might be incorrect if it proposed starting with biopsy, as imaging is usually the first step to guide the biopsy decision.
**Option C:** Could be incorrect if it recommended empirical antibiotic treatment, assuming the mass is due to infection, without first ruling out malignancy.
**Clinical Pearl / High-Yield Fact**
A key point to remember is that **testicular ultrasound** is the primary imaging modality for evaluating testicular masses due to its high sensitivity and specificity for distinguishing between solid and cystic lesions, and its ability to guide further management decisions.
**Correct Answer:** D. Ultrasound of scrotum
