What is the effect of rheumatic fever on the skin?

The effect of rheumatic fever on the skin is characterized by the formation of subcutaneous nodules over bony prominences. These nodules, known as rheumatic nodules, are firm, painless lumps that typically develop on areas such as the elbows, knees, and other sites of pressure or friction on the body. Their presence is a classic manifestation of rheumatic fever, which is a serious inflammatory condition that can arise following a streptococcal throat infection.

Rheumatic fever is not primarily associated with widespread rashes or severe bruising, nor does it cause chronic dryness and peeling of the skin. The unique appearance and location of these subcutaneous nodules serve as significant clinical markers for the diagnosis of rheumatic fever, along with other symptoms such as fever, joint pain, and carditis. Understanding this effect helps in recognizing the condition and differentiating it from other illnesses with skin manifestations.
