[Stewart-Treves syndrome complicating chronic idiopathic lymphedema]

[Primary congenital lymphedema: Milroy disease: the first case observed in the Department of Pediatrics at the University Hospital Yalgado Ouedraogo, Ouagadougou]

Congenital lymphedema is the accumulation of lymphatic fluid in the child's interstitial spaces. Milroy disease is a rare, hereditary, autosomal dominant condition showing incomplete penetrance. We report the case of a 7-year old little girl with Milroy disease examined for erysipelas on congenital big right leg. A family history of large congenital member existed. Physical examination showed big oedematous right leg painful to palpation, with skin lichenification and erysipelas. Paraclinical assessment objectified cutaneous lymphedema with vascular involvement suggestive of ectasia of the right saphenous vein. Female karyotype showed no abnormalities, despite the small chromosomal rearrangements. Treatment was based on physiotherapy, bandages, compression stockings and psychotherapy. This first case in Burkina Faso testifies to the rarity of the pathology but especially to the diagnostic difficulties related to the inadequacy of paraclinical investigations.
