**Core Concept**
A palpable fibrous plaque on the dorsal penile shaft is a clinical manifestation of a specific dermatological condition. This condition is characterized by the formation of a fibrotic lesion, which is a result of chronic inflammation and scarring.

**Why the Correct Answer is Right**
The correct answer is a classic example of Peyronie's disease, a condition where fibrous scar tissue forms on the penis, leading to a palpable plaque. This occurs due to the formation of collagen and fibrous tissue as a result of chronic inflammation, often caused by trauma or injury to the penis. The plaque can cause penile curvature, pain, and erectile dysfunction.
