Vascular malformations represent a heterogeneous spectrum of lesions that often present a diagnostic and therapeutic challenge, thus requiring a high index of clinical suspicion to reach a definitive diagnosis. Cloves syndrome is a rare overgrowth disorder of genetic etiology associated with a somatic activating mutation in PIK3CA, which is part of the PI3KAkt-mTOR intracellular signaling pathway. Clinically, it is characterized by congenital lipomatous overgrowth of any part of the body (mainly the thorax), accompanied by vascular and lymphatic malformations, epidermal nevi and structural abnormalities of the skeletal system such as scoliosis and alterations in the spine. The current therapeutic cornerstone for this syndrome is therapy with rapamycin, an mTOR pathway inhibitor. On the other hand, Klippel-Trenaunay syndrome is a complex vascular condition associated with overgrowth due t...
