**Core Concept**
Thrombocytopenia, macerated skin lesions, rash, and periostitis in a newborn are characteristic features of a congenital infection, specifically congenital syphilis. This condition occurs when the fetus is exposed to syphilis in utero, leading to various systemic manifestations.

**Why the Correct Answer is Right**
Congenital syphilis is caused by the transmission of Treponema pallidum from an infected mother to her fetus during pregnancy. The infection leads to thrombocytopenia due to bone marrow suppression, macerated skin lesions due to skin necrosis, rash due to skin involvement, and periostitis due to the infection of the periosteum, resulting in bone pain and swelling. The characteristic "snuffles" in newborns, which is a chronic nasal discharge, is another hallmark of congenital syphilis.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect as it does not match the clinical presentation described in the question.
**Option B:** This option is incorrect as it does not accurately describe the condition characterized by thrombocytopenia, macerated skin lesions, rash, and periostitis in a newborn.
**Option C:** This option is incorrect as it does not match the clinical presentation described in the question.

**Clinical Pearl / High-Yield Fact**
Congenital syphilis can be effectively prevented with prompt treatment of the mother during pregnancy, highlighting the importance of prenatal care and syphilis screening.
