Stages

Characteristics

Latent or subclinical condition

Swelling is not yet evident

stage 0

May be transient and may take months or years before overt swelling occurs (Stages I-III)

Stage I

Initial fluid accumulation relatively high in protein content (compared to “venous” edema)

Decreases with elevation of the limb

Stage II

Involves more changes in tissue structures that increase the risk of fibrosis, infection, and skin lesions.

Limb elevation alone rarely reduces tissue swelling.

Stage III

Lymphostatic “elephantiasis”.

Locker sign is absent.

Trophic skin changes (acanthosis, changes in skin character and thickness, subsequent fat deposition and fibrosis.
