Which are the symptoms of Cloves Syndrome?

CLOVES syndrome is a rare overgrowth disorder characterized by Congenital Lipomatous Overgrowth, Vascular malformations, Epidermal nevi, and Spinal/Skeletal anomalies. Symptoms are highly variable, typically manifesting at birth or in early infancy as asymmetric tissue overgrowth and complex vascular issues that require multidisciplinary clinical management.

What are the primary symptoms of CLOVES syndrome?

The name CLOVES syndrome serves as an acronym for its hallmark clinical features. Patients often present with a combination of the following manifestations:

• Congenital Lipomatous Overgrowth: Soft, fatty masses that are typically non-cancerous but can grow rapidly.


• Vascular malformations: Commonly low-flow venous or lymphatic malformations that may cause pain or swelling.


• Epidermal nevi: Skin lesions that are often verrucous (wart-like) and may darken over time.


• Spinal/Skeletal anomalies: Including scoliosis, wide feet, or localized gigantism of digits and limbs.

How do symptoms of CLOVES syndrome vary between patients?

The severity of CLOVES syndrome exists on a broad spectrum. While some individuals may have mild cutaneous findings, others experience significant orthopedic complications or severe vascular malformations that impact mobility. Because CLOVES syndrome is caused by a somatic mutation in the PIK3CA gene, the timing and distribution of the mutation during embryonic development dictate the specific areas and intensity of the overgrowth.

What are the early warning signs and progression?

Early signs often include asymmetric limb size at birth or the presence of soft, doughy masses on the trunk or extremities. As children with CLOVES syndrome grow, the skeletal overgrowth may lead to joint pain, restricted range of motion, or complications from scoliosis. It is critical to monitor for rapid changes in vascular malformations or sudden growth in fatty masses, as these can affect daily quality of life and physical function.

When should I seek immediate medical attention?

Families should seek urgent care if a patient with CLOVES syndrome experiences sudden, intense pain, significant swelling, signs of infection near a vascular malformation, or unexplained neurological symptoms related to spinal involvement. Regular screening with a specialized multidisciplinary team is essential to track the progression of CLOVES syndrome symptoms.
