Vesicular lesions are blisters caused by friction, burns, chemical exposure, or infection. They may resolve on their own or require treatment. Patients with large, changing, or non-healing lesions should see a doctor. Treatment options include draining the fluid, medication for infections, and topical preparations to soothe itching and burning. Patients should avoid scratching or picking at the lesion to prevent infection and scarring.
A vesicular lesion is a blister on the skin or another organ. Friction, burns, chemical exposure, and infection can cause vesicular lesions of various shapes and sizes. The blister may resolve on its own over time or require treatment, depending on the cause of the injury. Patients with large lesions that do not go away, increase in number, or appear to change color or shape should see a dermatologist or doctor for an evaluation.
A classic vesicular lesion is a thin bubble of fluid under the skin. The lesion may crackle or burst if it is large, and patients may experience pain and discomfort. The surrounding area may be red and warm, indicative of inflammation. If the blister ruptures, it will leak white, clear, or yellow fluid and expose the skin underneath. Premature rupture can put patients at risk of infection because the underlying skin has not fully healed.
Friction is a common cause of vesicular injury. People who put on new shoes or use unfamiliar tools may notice some blisters at the end of the day. Burns and chemical exposures are another cause. It is important to rinse the skin after such injuries and to avoid pinching any lesions that appear, as they protect the skin as it heals. If a blister is particularly large or painful, a doctor can treat it under sterile conditions to drain the fluid and make the patient feel more comfortable.
Infections are another likely cause, in which case the patient needs treatment for the infection to resolve the problem. Herpes viruses such as chicken pox and genital herpes are commonly associated with vesicular lesions. Patients can also develop this type of lesion in response to infections with other microbes such as parasites. A doctor will need to examine the lesion and run some tests to find out what’s going on and prescribe an appropriate medication to treat the infection.
Managing this condition can be difficult, because patients often want to scratch or scratch. Topical preparations are available to soothe the itching and burning. Some patients may find it helpful to soak in a bath tub with baking soda when itching becomes severe. Bandaging is another option, as is wearing gloves to prevent picking. Harvesting can expose patients to the risk of infection and scarring. In the case of young patients who don’t understand concerns, it can help provide distractions to prevent scratching.
