As healthcare providers, we often focus our attention on treating wounds after they occur. However, one of the most effective strategies for improving patient outcomes is recognizing the warning signs before skin breakdown begins. The skin often provides valuable clues that chronic edema, venous disease, lymphedema, or impaired circulation are progressing—and these changes should never be ignored.
Early identification allows clinicians to intervene with compression therapy, edema management, skin care, and patient education before a wound develops.
Below are seven important skin changes every clinician should recognize.

One of the earliest indicators of chronic venous insufficiency is hemosiderin staining. This appears as brown, rust-colored, or reddish discoloration around the lower legs and ankles.
When venous pressure remains elevated over time, red blood cells leak through damaged capillaries into surrounding tissues. As these cells break down, iron-containing hemosiderin is deposited in the skin, creating permanent discoloration.
Hemosiderin staining indicates chronic venous hypertension and should prompt evaluation for:
Brown discoloration is not simply a cosmetic issue—it is evidence of longstanding vascular dysfunction.
5
Fibrosis occurs when chronic inflammation causes excess collagen deposition within the tissues. The skin becomes:
Patients often describe the affected area as feeling “hard” or “tight.”
Fibrosis decreases tissue flexibility, impairs lymphatic transport, and reduces oxygen delivery to the skin, increasing the likelihood of skin breakdown and delayed wound healing.
4
Hyperkeratosis refers to excessive buildup of keratin on the skin surface, producing thick, rough, or scaly plaques.
It commonly develops in patients with:
The thickened skin can:
Treatment typically includes edema reduction, compression therapy, moisturization, and careful skin care.
5
Dry skin is more than an inconvenience—it represents a compromised skin barrier.
Repeated stretching from swelling reduces the skin’s ability to retain moisture, making it vulnerable to:
Daily moisturizing is a simple intervention that significantly reduces the risk of skin breakdown in patients with chronic edema.
5
Papillomatosis appears as small wart-like projections or cobblestone changes in the skin.
These growths develop from prolonged lymphatic congestion and chronic inflammation.
Papillomatosis indicates advanced lymphatic dysfunction and increases the risk of:
It is frequently seen in advanced untreated lymphedema.
5
Lipodermatosclerosis is characterized by inflammation and fibrosis of the skin and subcutaneous tissue caused by chronic venous disease.
Common findings include:
This condition significantly increases the risk of venous ulceration and often requires aggressive edema management and compression therapy.
5
A positive Stemmer Sign occurs when the clinician is unable to pinch and lift the skin at the base of the second toe (or finger).
Although not a skin condition itself, it is one of the most recognized clinical indicators of lymphedema.
A positive Stemmer Sign suggests impaired lymphatic transport and should prompt further evaluation and referral for lymphedema management.
Many chronic wounds do not appear suddenly. Instead, they develop after months—or even years—of progressive skin and tissue changes.
Recognizing these early warning signs gives clinicians the opportunity to intervene before skin breakdown occurs. Addressing edema, improving circulation, optimizing skin care, and initiating appropriate compression therapy can significantly reduce the risk of ulceration, infection, hospitalization, and impaired quality of life.
As healthcare professionals, we have the opportunity to shift from simply treating wounds to preventing them.
At the American Academy of Lymphatic and Wound Management (AALWM), we are committed to advancing clinician knowledge through evidence-based education in wound care, lymphedema management, compression therapy, and Complete Decongestive Therapy (CDT).
Whether you’re looking to expand your clinical skills or pursue specialized certification, our courses are designed to provide practical, hands-on education that translates directly into better patient care.
