While diabetic foot ulcers are common, there are less familiar wound types that should be recognized as well.

Because of its prevalence, a diabetic foot ulcer is a wound with which the general public is most familiar. According to Podiatry Today, up to 26.1 million people worldwide have the condition and, in the U.S, they occur at the rate of 6 percent among Medicare beneficiaries

But there are less common chronic wounds that also demand attention and specialized treatment when healing wounds. Here are a few other wound types that, while perhaps not as common, you should still know.

Vasculitic ulcers

Health Times stated that these wounds are the result of an inflammation of blood vessels, and specifically micro blood vessels, commonly found on the lower leg and feet. They often develop among patients with cancer, hepatitis B or those who have been exposed to harmful chemicals.

The severity of a vasculitic ulcer is determined by the location, whether the edges of the ulcer are flat or raised, if there are any bones or tendons are exposed and any possible discharge. This wound is generally treated with wound care products such as cortisone-based medications.

Necrotising fasciitis

According to the CDC, this is a bacterial skin infection better known as the “flesh-eating virus,” though it can be caused by one of several types of dangerous bacteria including: Escherichia coli, Group A Streptococcus and Klebsiella. The bacteria enters the skin through a cut, burn, scrape, burn or insect bite and, if left untreated, can be fatal. It can spread more rapidly in people with compromised immune systems.

Symptoms include muscle soreness, warm skin, a purplish bruise that spreads, as well as fever and chills. Antibiotics and surgical procedures to remove dead tissue are part of the treatment.

Pyoderma gangrenosum

This is a rare skin condition (3-10 cases per million) that most commonly occurs on the leg, according to the Mayo Clinic. While the cause is not known (though believed to be the result of an immune disorder), those who suffer from arthritis, ulcerative colitis and Crohn’s disease are at risk of developing pyoderma gangrenous. While the ulcers can be treated, scars may result and recurrences are possible.

Calciphylaxis

Primarily, this occurs in patients receiving hemodialysis (kidney cleaning) treatment. The blood vessels calcify, a clot develops and blood is cut off from tissues, creating serious wounds and the condition can be fatal. Diagnosis is primarily done by observing skin lesions that are purple-black in color, have a leathery feel and are very painful. Pain management includes oral medication and a hydrogel dressing with lidocaine applied.
