Yes, a scar can reopen after years due to underlying issues like severe malnutrition (scurvy), certain inflammatory conditions (sarcoidosis), aging skin losing elasticity, infections, or significant pressure/trauma, disrupting the weaker scar tissue that never fully matched original skin strength, even if it seemed healed. While most scars fade, deeper ones with lost tissue or poor initial repair are prone to breaking down, especially if compromised by systemic health problems or physical stress.
Reopening of old wounds.
There isn't enough collagen left in your body to continue creating scar tissue, so old wounds may start opening.
Some scars cause problems months or years later. As nerve endings grow back, the scar may become painful or itchy.
A small number of patients manifest wound infections several months to several years after their operations.
A hypertrophic scar is a thick raised scar that's an abnormal response to wound healing. They more commonly occur in taut skin areas following skin trauma, burns or surgical incisions. Treatments include medication, freezing, injections, lasers and surgery.
The etiology of cancers occurring in scars is not fully understood, although the prevailing hypotheses include prolonged proliferation due to chronic inflammation and irritation of tissue, ongoing exposure of tissues to toxins and co-carcinogens after the injury, and poor vascularization of the scar tissue resulting in ...
Reactivation of pre-existing scars, as a manifestation of cutaneous sarcoidosis, is uncommon and the clinical significance of this odd symptom often remains unrecognised. In the appropriate setting a skin biopsy may serve to establish the diagnosis of sarcoidosis and avoid more invasive attempts at obtaining tissue.
This is because scar tissue can continue to change and adapt over time. Those fibrosis and pesky adhesions can form long after everything seemed healed. And when they mess with nerves or restrict your natural movement, it can lead to some serious discomfort or even sharp, ongoing pain.
Thick, irregular scarring, typically on the earlobes, shoulders, cheeks or middle chest. Shiny, hairless, lumpy, raised skin.
Characteristics of a Sepsis Scab
Unlike regular scabs, sepsis-related scabs are typically surrounded by discolored skin and may ooze pus or other fluids. This sinister appearance is a clear sign that your body is battling something more severe than a typical scrape.
Definition. Scars that form a depression compared to the level of the surrounding skin because of damage to the collagen, fat or other tissues below the skin. [
A keloid scar is when a scar keeps growing and becomes bigger than the original wound. It can happen if you have too much of a substance called collagen in your skin. It can happen after any sort of injury or damage to your skin such as a cut, burn, surgery, acne or a body piercing.
Ensure adequate intake of protein, carbohydrates, and vitamins A, B, C, and D. These nutrients support the inflammatory process and collagen synthesis, which are vital for wound repair. Additionally, minerals like zinc and iron contribute to effective healing.
Because the body wants to heal the tissue as quickly as possible, it lays the collagen fibres down haphazardly instead of in neat rows as with the surrounding healthy tissue. This causes the scar tissue to be thicker and less tensile than healthy tissue and often becomes a source of pain.

Sun exposure: If a scar has been exposed to the sun without protection, it can become damaged and prone to developing skin cancer. Scars formed from injuries or surgeries in sun-exposed areas like the face, arms, or neck are especially at risk.
Types of Scars
Some types are more likely to raise concerns than others: Hypertrophic scars — Raised, red scars that remain within the boundaries of the original wound. Keloids — Thick, raised scars that grow beyond the original wound area, sometimes recurring after removal.
It is known that keloids do not transform into cancer or any other disease. However, if left untreated, they do not regress or disappear. Keloids can be mistaken for skin cancers. To rule this out, a tissue sample may need to be taken, followed by a pathological examination.
Scar tissue often has trouble holding onto moisture, which can dry out the skin and cause itching. If scar tissue becomes tight or starts pulling, it can cause itching because it's less flexible than normal skin. Even older scars can start itching again, for example, due to changes in the weather or hormonal shifts.
Damaged nerve endings send abnormal signals that cause stinging and pain. Scar tissue doesn't have the same flexibility, and those nerve endings may have been involved in the initial injury. Nonpainful stimulus giving you pain is abnormal because those damaged nerve endings are receiving signals incorrectly.
Scar tissue typically begins to form the first day after surgery, but it may not produce symptoms for months, years — or ever.
Scurvy causes the body to disintegrate. Skin develops ulcers, gums putrefy, old wounds re-open.
The causes of dehiscence are similar to the causes of poor wound healing and include ischemia, infection, increased abdominal pressure, diabetes, malnutrition, smoking, and obesity. [1] Superficial dehiscence is when the wound edges begin to separate and by increased bleeding or drainage at the site.
In some people, the scar tissue keeps forming long after the wound heals. This extra scar tissue causes the raised area on your skin. Doctors still aren't sure why some people's skin scars this way. Many different types of skin injuries can lead to a keloid.
