Peripheral pitting edema, as shown in the illustration, is the more common type, resulting from water retention.
Myxedema's characteristic physical sign is non-pitting edema, in contrast to pitting edema. [1] Myxedema can also occur in the lower leg (pretibial myxedema) and behind the eyes (exophthalmos). [citation needed] Severe cases, requiring hospitalization can exhibit signs of hypothermia, hypoglycemia, hypotension, respiratory depression, and coma.
The difference in circumference is less than 4 cm (1.6 in) and no other tissue changes are present. Grade 2 (moderate edema): Involves an entire limb or corresponding quadrant of the trunk. Difference in circumference is 4–6 cm (1.6–2.4 in). Tissue changes, such as pitting, are apparent. The patient may experience erysipelas.

Severe peripheral pitting edema. Right-sided heart failure is often caused by pulmonary heart disease (cor pulmonale), which is typically caused by issues with pulmonary circulation such as pulmonary hypertension or pulmonic stenosis. Physical examination may reveal pitting peripheral edema, ascites, liver enlargement, and spleen enlargement.
Remitting seronegative symmetrical synovitis with pitting edema (or sometimes RS 3 PE) is a rare syndrome identified by symmetric polyarthritis, synovitis, acute pitting edema (swelling) of the back of the hands and/or feet, and a negative serum rheumatoid factor. [2]
Pretibial myxedema is almost always preceded by the ocular signs found in Graves' disease. [3] It usually presents itself as a waxy, discolored induration of the skin—classically described as having a so-called peau d'orange (orange peel) appearance—on the anterior aspect of the lower legs, spreading to the dorsum of the feet, or as a non-localised, non-pitting edema of the skin in the ...
