    What is (are) Hereditary lymphedema type II ?
    ### Response:
    Hereditary lymphedema type II is a primary lymphedema that results from abnormal transport of lymph fluid. Individuals with this condition usually develop swelling in the lower legs and feet during puberty. Some affected individuals develop a non-contagious skin infection called cellulitis, which can further damage the lymphatic vessels (the thin tubes that carry lymph fluid).
