Definition:

Congenital lipomatous overgrowth, vascular malformations, and epidermal nevi (CLOVE) syndrome is a recently delineated disorder that comprises vascular malformations (typically truncal), dysregulated adipose tissue, scoliosis, enlarged bony structures (typically of the legs) without progressive or distorting bony overgrowth. The key feature of this syndrome is a truncal lipomatous mass of variable size that is noted at birth. The fatty growths often extend from the trunk into the retroperitoneum, mediastinum, thoracic cavity, and epidural space. Deeper fast-flow and slow-flow vascular anomalies become evident early in childhood. Most acral deformities become accentuated with growth, are often symmetrical, are not rapidly progressive, and are commonly misdiagnosed as Proteus syndrome. This syndrome is caused by somatic activating mutations in PIK3CA.
