In immunosuppressed people or patients on chemotherapy, this condition can involve several dermatomes. Herpes zoster lesions are more linear and restricted to one side of the body following a dermatome. Herpes simplex causes small, closely grouped vesicles on a red base and these can be located anywhere on the body, not just the most common sites (lips or genitals). Pain preceding the appearance of the skin lesions is a very important clue to this diagnosis. Both start as a red macule, which soon becomes raised and forms a vesicle. Herpes simplex and herpes zoster cause painful blisters. Ideally, everyone should be treated on the same day and the process repeated a week later. A topical scabicide should be used over the entire skin surface of the infant, and from the neck down for the others. Treatment for scabies should involve not only the infant, but all members of the household (older children and adults). Using a dermatoscope greatly assists this process, because the head parts of the scabies mite can be seen as a dark triangle under the skin and the burrows of the mite become much more obvious. This is often mistaken for eczema.īoth conditions can coexist and when this occurs, making a correct diagnosis can be a challenge. Unlike scabies in an adult, scabies in a small child or infant can present with small blisters on the base of the feet and the palms. Insect bites are often grouped or linear. Such blisters are often formed on the lower legs and should be treated in the same way as friction blisters, along with oral antihistamines and topical steroids to stop irritation. Insect bites frequently blister, probably as a result of being scratched. Most friction blisters heal without problem, but they can sometimes lead to cellulitis and septicaemia, especially in patients with diabetes, the elderly or the immunosuppressed. If the blister roof is already fully or partially removed, it needs to be treated as a wound, with dressings and possibly an antiseptic or antibiotic cream. Gel plasters can protect smaller blisters and prevent new ones. This relieves the discomfort and protects the site from infection. Such blisters are best managed by draining the fluid from bigger ones with a sterile needle, but leaving the blister roof intact to serve as a dressing. Usually there is no problem with this diagnosis. Poorly fitting shoes are a frequent cause, while on the palms they occur from gripping tools or sports equipment. Friction blistersįriction blisters are very common and occur on the soles, palms and heels, where the stratum corneum is thicker (friction on thinner skin causes erosions). Small blisters under 0.5cm are called vesicles, while larger blisters are known as bullae.

People with a weakened immune system may have larger or more bumps. Sometimes these bumps itch and get irritated. They are rarely on the palms of the hands or soles of the feet. They can grow alone or in groups almost anywhere on the skin, including the face, neck, arms, legs, abdomen and genital area. Molluscum are sometimes called water warts. There are no approved treatments in either prescription or over-the-counter form for the condition, which will typically go away on its own in six to 12 months but could last up to five years.
