Lymphedema is a swelling of soft tissues, the result of accumulation of increased quantities of lymph. A useful clinical classification by Allen, Barker, and Hines,1 modified by Duryee,* divides all cases into two main groups; inflammatory and noninflammatory.
Noninflammatory
Primary
Congenital lymphedema
Secondary
Malignant occlusion
Surgical removal of lymph nodes
Pressure
Radiation therapy
Venous insufficiency
Inflammatory
Primary (single or recurrent acute and chronic)
Secondary (single or recurrent acute and chronic)
Trichophytosis
Systemic disease
Local tissue injury or inflammation
Filariasis
