Table 1.

Clinical criteria of staging lymphedema (modified from ISL).

Stage	Clinical findings
0	A latent or sub-clinical condition is not evident despite impaired lymph transport
1	Early accumulation of fluid with relatively high protein content subsides with extremity elevation. Pitting may occur
2	Extremity elevation alone rarely reduces tissue swelling, pitting is manifested, and extremities may or may not pit as excess fat and fibrosis supervenes
3	Lymphostatic elephantiasis where pitting can be absent, trophic skin changes including acanthosis, further deposition of fat and fibrosis and warty overgrowths have developed
