When your child comes to you with a rash, don鈥檛 panic鈥攜et. Many childhood rashes are simple to treat or require time to go away. Cindy Gellner, MD, a pediatrician at 麻豆学生精品版, says the five most common rashes she sees are:
- Eczema (atopic dermatitis)
- Molluscum contagiosum
- Pityriasis Alba
- Coxsackievirus (hand foot mouth disease)
- Diaper Rash
Eczema
There are different types of eczema (intrinsic, flexural, dyshidrotic, nummular), but Gellner says they're all very similar: an itchy, dry, scaly, often red rash likely to affect people with allergies or asthma.
Eczema is not contagious and can be treated with lotions for sensitive skin (no fragrance or dye) or topical steroids such as hydrocortisone or a prescription strength steroid cream if the rash is severe.
Gellner advises not to use steroid creams on a regular basis because it can thin the skin, although eczema is often a lifelong condition. However, without any treatment, eczema can crack the skin, which can lead to a bacterial skin infection called .
Molluscum Contagiosum
is a viral rash caused by the poxvirus and it's normally seen in toddlers through elementary age. 鈥淎t the center of the small flesh-colored papules is a white core," Gellner says. "That is essentially where the virus lives and eventually comes out. It basically looks like the little papule has a belly button.鈥
Gellner usually lets the rash run its course because the treatment can sometimes be worse. 鈥淭he rash is actually harmless, but it is contagious. The body's immune system will eventually kill the virus, though it can take months or even a couple of years.
Pityriasis Alba
Pityriasis Alba is the loss of skin pigment from melanin due to skin irritation. The hypopigmented patches usually appear on the face, upper chest, upper back, and the upper arms of people with dark skin. While some suspect it's caused by a vitamin deficieny, pityriasis alba is often caused by dry skin. It is not contagious.
鈥淭here鈥檚 nothing you can do to make it heal faster, but if you keep the skin hydrated you might avoid triggering more patches,鈥 Gellner says. 鈥淭he bottom line is you just have to wait for the skin cells to start making pigment again.鈥
Coxsackievirus (Hand, Foot, and Mouth Disease)
鈥淚 always joke with parents that it should be called hand-foot-butt-mouth disease because that鈥檚 where the rash appears,鈥 Gellner says. 鈥淭he classic case is red papules on the palms of the hands, soles of the feet, and on the buttocks. You can also get the rash around and inside the mouth.鈥
tends to show up in the summer and the fall. The rash on the hands and feet are usually painless, but the ones in the mouth can be painful. It鈥檚 also highly contagious and can last about seven to 10 days. Gellner advises to keep children with hand, foot, and mouth disease well hydrated.
Diaper Rash (Candidal and Irritant)
While yeast is normally on our skin, dark and moist environments can make yeast spread and cause a candida diaper rash.
鈥淐andida diaper rashes have what we call satellite lesions鈥攁 red bumpy rash, usually on the front with little red bumps on the fringe area and down the legs," Gellner says. "It鈥檚 very itchy and can make the skin peel if it鈥檚 not treated.鈥
Gellner also sees children with standard diaper rashes, mostly from irritation. She advises parents to use diaper rash cream and change diapers frequently.
When to Worry: Purple Paint Specks
So, when might you need to worry? Gellner says to act immediately if your child has something that looks like purplish paint on their legs. 鈥淟ike somebody took a paint brush with dark purple paint and spattered it on them like tiny dots." This is a sign of a serious infection such as meningitis or idiopathic thrombocytic purpura. These conditions must be treated at a hospital.
Keep the Natural Moisture Barrier
The body has a natural protective moisture barrier that helps keep out bad bacteria. Too much bathing and chemicals can break it down.
鈥淜ids usually don't need a bath every single day and definitely not bath bombs,鈥 Gellner says. 鈥淪ome parents will overdo baths and then their kids come in with dry, irritated skin. It鈥檚 important to keep the body鈥檚 natural moisture barrier intact.鈥
