## **Core Concept**
The question tests understanding of penile anatomy and the clinical presentation of penile fracture. The penis is enveloped by several layers: the skin, Dartos fascia (or superficial fascia), Buck's fascia (or deep fascia), and the tunica albuginea, which directly surrounds the corpora cavernosa and the corpus spongiosum. A fracture of the penis typically involves a tear in the tunica albuginea.

## **Why the Correct Answer is Right**
In the case of a penile fracture with rupture of the tunica albuginea but with Buck's fascia intact, the swelling and hematoma are usually confined to the shaft of the penis. This is because Buck's fascia, which surrounds the corpora cavernosa, corpus spongiosum, and the tunica albuginea, effectively contains the bleeding and prevents the hematoma from extending beyond the penile shaft. Clinically, this would present as a swollen and painful penis with a significant deformity but without significant extension of the hematoma into the scrotum or abdominal wall.

## **Why Each Wrong Option is Incorrect**
- **Option A:** This option is incorrect because if the hematoma extends into the scrotum or abdominal wall, it implies that Buck's fascia has been breached, which contradicts the premise of the question.
- **Option B:** This option might seem plausible but does not directly relate to the typical clinical findings associated with a penile fracture and intact Buck's fascia.
- **Option D:** This option is incorrect because the presence of a penile fracture with intact Buck's fascia does not typically lead to a urethral injury being the predominant clinical feature; rather, the mechanical disruption and pain are more immediate concerns.

## **Clinical Pearl / High-Yield Fact**
A key clinical pearl is that a penile fracture often results from a direct blow to the erect penis, commonly during sexual activity. The patient typically reports a "cracking" sound and immediate detumescence, followed by pain, swelling, and deformity. The integrity of Buck's fascia dictates the extent of hematoma spread and clinical presentation.

## **Correct Answer:** C.
