19

Brunner Clinical Classification Of lymphedema

Sub clinical (No clinically apparent lymphedema but histo abnormalities present)

G1 Edema pits on pressure & swelling disappears on elevation and bed rest

G2 Edema neither pits nor reduce upon elevation

G3 Edema is associated with irreversible skin changes fibrosis papillae

20

D/f b/w Type 1 lymphedema and type 2 lymphedema

Both are familial forms of Pri lymphedema

Type 1
-Auto dominant
-brawny lymphedema Of both legs
-Develops from birth or before puberty
-Mutation Of VEGF gene on chromosome 5
-Also known as Nonne-Milroy Or simple Milroy disease

Type 2
-auto dominant but not in all cases
-lymphedema Of one or both legs but involve arms
-Develop b/w puberty and middle age (50 yrs)

21

Lymphedema occur at d/f ages

Lymphedema Congenita
-Below 2 yrs old
-more common in males
-b/L and involve the whole leg

Lymphedema Praecox
-Age Of onset 2-35 yrs
-More common in females
-U/L and extends only to the knee

Lymphedema Tarda
-Age Of onset >35yrs

22

Important points

-Lymphedema developing for first time after 50 yrs should prompt a thorough search for malignancy

-lymphedema associated with malignancy commences proximally in the thigh rather than distally

23

Browse Lymphangiographic Classification

Three types of it
-Congenital hyperplasia
-Distal obliteration
-Proximal obliteration

Congenital hyperplasia
-A congenital onset edema Seen mostly in males involves whole leg with Intermediate progression though has a +ve Fx hx

Proximal Obliteration
-A Edema occurs at any age Seen in both genders involve whole leg and thigh only with rapid progression though -ve fx hx

Distal obliteration
-A Edema occurs at puberty seen mostly in females involve ankle & calf with slow progression though often +ve fx hx

24

What is Podoconiosis?

One of the cause of Secondary lymphedema which is non filarial non infective blockage of limb lymphocytics by silica particles

25

What is the MCC Secondary lymphedema worldwide?

Filariasis

26
