**Core Concept**
Secondary syphilis is a stage of syphilis characterized by the dissemination of the causative bacterium, *Treponema pallidum*, to various organs and tissues, leading to a wide range of systemic manifestations. The clinical features of secondary syphilis are diverse and can involve the skin, mucous membranes, lymph nodes, and other organs.

**Why the Correct Answer is Right**
In secondary syphilis, skin manifestations are common, including a characteristic rash that can be macular, papular, or pustular. Mucous membrane involvement is also frequent, with lesions appearing on the oral mucosa, cervix, and vulva. Lymphadenopathy, particularly in the neck, is a common finding. However, one feature that is not typically associated with secondary syphilis is the presence of a severe, diffuse, or migratory arthritis, which is more characteristic of early or late syphilis.

**Clinical Pearl / High-Yield Fact**
It's essential to note that the clinical features of syphilis can be highly variable and nonspecific, making diagnosis challenging. However, a careful history, physical examination, and laboratory testing, including serological tests and darkfield microscopy, can help confirm the diagnosis.

**Correct Answer:** D.
