Proteus syndrome is a rare genetic disorder [1] that can cause tissue overgrowth involving all three embryonic lineages. Patients with Proteus syndrome tend to have an increased risk of embryonic tumor development. [2] The clinical symptoms and radiographic findings of Proteus syndrome are highly variable, as are its orthopedic manifestations ...
Children with some overgrowth syndromes such as Klippel–Trénaunay syndrome can be readily detectable at birth. [3] In contrast, other overgrowth syndromes such as Proteus syndrome usually present in the postnatal period, characteristically between the second and third year of life. [2]
Other entities which are accompanied by multiple lipomas include Proteus syndrome, Cowden syndrome and related disorders due to PTEN gene mutations, benign symmetric lipomatosis (Madelung disease), Dercum's Disease, familial lipodystrophy, hibernomas, epidural steroid injections with epidural lipomatosis, [6] and familial angiolipomatosis.
Proteus includes pathogens responsible for many human urinary tract infections. [3] P. mirabilis causes wound and urinary tract infections. Most strains of P. mirabilis are sensitive to ampicillin and cephalosporins. P. vulgaris is not sensitive to these antibiotics but ticarcillin. However, this organism is isolated less often in the ...
CLOVES syndrome is closely linked to other overgrowth disorders like proteus syndrome, Klippel–Trénaunay syndrome, Sturge–Weber syndrome, and hemihypertrophy, to name a few. 'CLOVES' is an acronym for: [2] [3] C is for congenital. L is for lipomatous, which means pertaining to or resembling a benign tumor made up of mature fat cells. Most ...
Proteus-like syndrome (PLS) is a condition similar to Proteus syndrome, but with an uncertain cause. [1] It's characterized by skeletal and hamartous overgrowth of multiple tissues, nevi in cerebriform connective tissue, blood vessel malformations and linear epidermal nevi. [2] [3]
Cohen was born in Boston, Massachusetts, and studied at the University of Michigan, Tufts University, the University of Minnesota, and Boston University.His post-graduate training included a fellowship in pathology and medical genetics with Robert Gorlin (1923–2006), an oral pathologist and geneticist who described a large number of syndromes, including one they delineated together known as ...
Mutations in PIK3CA cause over-activity of PI3K which in turn leads to altered growth of cells and tissues which is thought to be important for overgrowth and malformations in PROS. [5] Different presentations of PROS diseases are likely explained by acquisition of the mutation in different time points and different cell types during embryonic ...
