- Sores in the mouth and nose (mucous membrane sores)
- Hair loss, sometimes caused by discoid lesions
- Purple spots (due to broken blood vessels) on the legs

Cold sores are highly contagious, so it is possible to get a cold sore from,
- Kissing an infected person
- Sharing utensils and drinking from the same glass as an infected person
- Oral sex
Before a blister even develops, you may notice burning, tingling, pain, or itching around the affected area of the lip. If this is your first time dealing with a cold sore, it is common for the first outbreak to be the worst. In this case, you may develop a fever, body aches, or other flu-like symptoms.
When it comes to treating a cold sore, you can find simple over-the-counter creams that help to ease symptoms. If you deal with severe cold sore outbreaks you may wish to talk with your dermatologist about a prescription antiviral medication, that can help to reduce the length of your outbreak and reduce symptom severity.
Cold sores and canker sores can often be mistaken for each other, but they are not the same. First, cold sores usually develop on the lips while canker sore cause painful sores to develop in the mouth. Secondly, cold sores are due to a virus while we still don’t know exactly what causes canker sores.

How is molluscum contagiosum contracted?
You may be wondering how your child contracted this poxvirus. There are several ways to transmit this viral infection: skin-to-skin contact, sharing items such as towels or clothes, sexual transmission (in adults), and scratching your own lesions (this can lead to further spreading of the papules).
It can take anywhere from two weeks to six months to develop symptoms after exposure. Once a child or person has molluscum contagiosum they typically aren’t infected again in the future.
How is this condition diagnosed?
If you notice any bumps on your child that persist for days, you must consult your dermatologist to find out what’s going on. A simple dermatoscopy (a painless, non-invasive procedure that allows your dermatologist to examine a skin lesion or growth) can determine whether the papule is due to molluscum contagiosum. If MC is not suspected, your dermatologist may biopsy the bump for further evaluation.
How is molluscum contagiosum treated?
Since this is the result of a viral infection, antibiotics will not be an effective treatment option. In fact, the body simply needs time to fight the virus. Your dermatologist may just tell you to wait until the infection runs its course and clears up on its own.
If the papules are widespread and affecting your teen’s appearance and self-esteem, then you may wish to talk with a dermatologist about ways to get rid of the spots. Cryotherapy or certain creams may be recommended to treat and get rid of these spots.
If you are living with others, it’s important to avoid sharing any clothing or towels with the infected child or person. Make sure that your child does not scratch the bumps, which can lead to further spreading of the infection.
If your child is dealing with a rash, raised bumps, or any skin problems and you’re not sure what’s going on, it’s best to talk with a qualified dermatologist who can easily diagnose the issue and provide you with effective solutions for how to treat it.
Breaking out in a rash can be concerning, particularly if you don't know what's causing it. Skin rashes are a common issue seen by the doctors at Applegarth Dermatology in Valparaiso, Indiana, with ringworm being one of the main causes. If you're wondering about what's causing your rash, you've come to the right place. Dr William Applegarth and physician's assistant Thomas Sandin delve into the topic of ringworm in this post.
What is ringworm?
Contrary to its name and reputation, ringworm isn't caused by a parasite. It's actually caused by a fungus, the same one responsible for athlete's foot and jock itch. Ringworm, or dermatophytosis, causes a reddened and scaly rash to appear in nickel- or quarter-sized patches on the body. It is annular, or ring-shaped, with the middle section typically left unaffected. It can also develop on the scalp, where it can cause bald patches to develop. Ringworm can be intensely itchy and is very contagious. It's easily spread from person to person as well as by touching animals, particularly cats and cattle, who carry it. It's typically treated with a topical antifungal ointment.
If it's not ringworm, what is it?
There are a few other skin conditions that can mimic the appearance of ringworm. These include granuloma annulare, which produces smooth (rather than scaly rings) of inflammation on the skin, as well as pityriasis rosea, which is thought to be the result of a viral infection. Patches of psoriasis or eczema can also look like ringworm. Because it's often not immediately clear what's causing your rash, it's important to contact your Valparaiso dermatologist when you develop a rash that doesn't clear up on its own in a few days.
Fortunately, ringworm and other skin rashes are easily treatable with the help of your Valparaiso dermatologist. Contact Applegarth Dermatology at (219) 548-0360 for an appointment with Dr. William Applegarth or Thomas Sandin, PA.

Most people don’t know what impetigo is. Maybe you haven’t even heard of it. This contagious bacterial skin infection is most often seen in babies and children; however, adults can catch this infection, too. Dermatologists often see a rise in impetigo cases during the summer. How does impetigo even happen in the first place?
Well, our skin is home to millions of bacteria. Most of them are actually good bacteria that help you stay healthy; however, bad bacteria can develop on the skin too. If these bad bacteria can get into a wound or opening in the skin, this can cause impetigo.
What are the symptoms?
Impetigo causes red bumps mostly on the arms, legs, and face. These bumps will eventually turn into blisters that will crust over. The skin under and around the blisters may look raw. At first, you may only notice one or two spots; however, the condition will continue to spread. Bumps may itch or also be tender.
Who is at risk for impetigo?
As we said, we often see this condition in children and infants; however, certain factors can also put adults at risk. You may be more at risk for impetigo if you have been diagnosed with,
- Scabies
- HIV/AIDS
- Liver conditions
- Diabetes
- Eczema or dermatitis
Since many skin conditions cause painful blisters to form it’s important to see a dermatologist right away for a proper diagnosis. When you come into the office, our skin doctor will ask you questions about your symptoms and medical history to help rule out what conditions it could be. A physical examination performed by a qualified dermatologist is often all that’s needed to make a diagnosis; however, we may collect fluid from the blister to look for the presence of bacteria.
How do you treat impetigo?
It’s important to see a doctor for treatment because impetigo will require antibiotics. Depending on the severity of the blisters, your dermatologist may simply prescribe an antibiotic cream, while those with more widely affected areas or more severe symptoms may require oral antibiotics. Once you start taking the medication you should recover within a week.
If you or your little one is dealing with symptoms of impetigo you must see a dermatology professional right away for a proper diagnosis and treatment.
