Ulcer (dermatology)

Ulcer (dermatology)

An ulcer in dermatology refers to a sore on the skin or a mucous membrane, accompanied by the disintegration of tissue. Ulcers can result in complete loss of the epidermis and often portions of the dermis and even subcutaneous fat. Ulcers are most common on the skin of the lower extremities and in the gastrointestinal tract.

Causes

Ulcers may be caused by a variety of factors, but the most common are infection, ischemia, or malignancy. Other causes include trauma, inflammatory processes, or damage to the skin or mucous membranes.

Symptoms

Symptoms of ulcers can vary depending on the cause, but they often include pain, bleeding, or discharge. The skin around the ulcer may be red, swollen, or tender. In severe cases, ulcers can lead to gangrene or sepsis.

Diagnosis

Diagnosis of ulcers typically involves a physical examination and a review of the patient's medical history. In some cases, a biopsy may be performed to rule out malignancy. Other diagnostic tests may include blood tests, imaging studies, or endoscopy.

Treatment

Treatment of ulcers depends on the cause. For ulcers caused by infection, antibiotics may be prescribed. For ulcers caused by ischemia, treatment may involve improving blood flow to the area. In cases of malignancy, treatment may involve surgery, radiation therapy, or chemotherapy.
