Answer: (A)

Noonan Syndrome with Multiple Lentigines, also known as LEOPARD syndrome, is characterized by the presence of distinctive cutaneous findings, primarily multiple lentigines, which are small brown spots on the skin. These brown spots resemble freckles and are a hallmark feature of the condition. The presence of these lentigines typically appears in childhood or early adulthood and is distributed over various parts of the body. While other symptoms can occur in patients with Noonan Syndrome and related conditions, the specific association of brown skin spots is a defining aspect of Noonan Syndrome with Multiple Lentigines. Understanding this characteristic can help in the clinical diagnosis of the syndrome, guiding appropriate management and surveillance for potential complications associated with the condition.
