| A rare PIK3CA (phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha) related overgrowth syndrome disease with characteristics of segmental and progressive overgrowth, predominantly involving the adipose tissue, or a mixture of adipose and fibrous tissue, with variable involvement of subcutaneous and muscular tissue, as well as skeletal overgrowth. Overgrowth severity and range is highly variable although frequently it is asymmetric and disproportionate, it affects lower extremities more than the upper ones and progresses in a distal to proximal patten. Congenital overgrowth is typically associated. |
