BACKGROUND: CLOVES (congenital lipomatous overgrowth, vascular malformations, epidermal nevi, scoliosis/skeletal/spinal) syndrome is a rare and progressive genetic disorder resulting from somatic mosaicism in activating mutations in the phosphatidylinositol-4,5- bisphosphate 3-kinase catalytic subunit alpha (PIK3CA) gene. PIK3CA is a cell growth master regulator where gain of function mutations give rise to abnormal activation of the PI3K-AKT- mammalian target of rapamycin (mTOR) pathway. Treatment with sirolimus, an mTOR inhibitor, may therefore be of benefit in patients with CLOVES syndrome. OBJECTIVE: Here we describe the efficacy and toxicity of sirolimus in a pediatric patient with progressive CLOVES syndrome. RESULTS: The child presented with a large and painful abdominal malformation, massive overgrowth of his feet, limb length discrepancy and genu valgum. There was dramatic clinical and radiographic improvement in the size and comfort of his abdominal mass within several months of initiating medical therapy. This, combined with orthopaedic care of his genu valgum, leg length discrepancy, and overgrowth of his feet, has allowed for significant functional gains. CONCLUSIONS: Multidisciplinary care is essential for comfort and functional gains in patients with CLOVES syndrome, particularly those with severe symptoms. Close monitoring while on sirolimus medical therapy combined with frequent reassessment of orthopedic needs can dramatically improve patient quality of life and outcomes.
