[Lymphedema complicated with verrucous papillomatosis]

Limb lymphedemas are due to a malfunction of the lymphatic system responsible for lymph stasis in the interstitial tissue and secondarily to an increase in the volume of the affected limb. They are divided into primary lymphedema (PL) and secondary lymphedema (SL). SLs develop most frequently in lower limbs after breast cancer treatment while lymphedemas are either secondary (iatrogenic or infectious) or primitive, most often sporadic, sometimes familial or they can be part of syndromes resulting in malformations and/or more complex genetics in upper limbs. The diagnosis of lymphedema is essentially based on clinical examination. Erysipelas are the main complication of lymphedema. Other abnormalities are often visible: yellowish skin and nails, lymphangiectasias, keratotic papules with papillomatosis, lichenified plaques. The main differential diagnosis in patients with limb lymphedema is lipoedema, defined as body fat distribution from the hips up to the ankles and affecting almost exclusively obese women. We report the case of a 30 year old man with left lower limb lymphedema occurred at puberty complicated by verrucous papillomatosis. It is a late-revelation congenital lymphedema.
