Molluscum contagiosum is a common viral skin infection of childhood that causes localised clusters of umbilicated epidermal papules.
Molluscum contagiosum mainly affects infants and young children under the age of 10 years. It is more prevalentin warm climates than cool ones, and in overcrowded environments. Adolescents and adults are less often infected. Molluscum contagiosum tends to be more numerous and last longer in children who also have atopic dermatitis, due to deficienc...
Molluscum contagiosum is caused by a poxvirus, the molluscum contagiosum virus. There are at least 4 viral subtypes. There are several ways the virus can spread: 1. Direct skin-to-skin contact 2. Indirect contact via shared towels or other items 3. Auto-inoculationinto another site by scratching or shaving 4. Sexual transmission in adults. Transmis...
Molluscum contagiosum presents as clusters of small round papules. The papules range in size from 1 to 6 mm and may be white, pink or brown. They often have a waxy, shiny look with a small central pit (this appearance is sometimes described as umbilicated). Each papulecontains white cheesy material. There may be few or hundreds of papules on one in...
Secondary bacterial infection from scratching (impetigo)Conjunctivitiswhen the eyelid is infectedNumerous and widespread molluscum contagiosum that are larger than usual may occur in immune-deficient patients (such as uncontrolled HIV infection or in patients on immune suppressing drugs), and...Molluscum contagiosum is usually recognised by its characteristic clinical appearance or on dermatoscopy. White molluscum bodies can often be expressed from the centre of the papules. Sometimes, the diagnosis is made on skin biopsy. Histopathology shows characteristic intracytoplasmic inclusionbodies.
There is no single perfect treatment of molluscum contagiosum since we are currently unable to kill the virus. In many cases no specific treatment is necessary.
In immune competent hosts, molluscum contagiosum is a relatively harmless. The papules may persistfor up to 2 years or longer. In children, about half of cases have cleared by 12 months, and two-thirds by 18 months, with or without treatment. Contact with another infected individual later on can lead to a new crop. Infection can be very persistent ...
Molluscum can also trigger a surrounding rough itchy rash in some children. This is common in children with dry or sensitive skin. If you notice spreading redness, warmth, and/or pus, your doctor can examine for signs of infection. Infection of molluscum is rare. Most often, these signs are signs
Molluscum is a common viral infection of childhood that causes a benign and self-limiting infection of the skin. Lesions can occur anywhere on the body and a child may develop a few or many lesions. Molluscum is spread by direct skin-to-skin contact, fomites (eg towels) or auto-inoculation by scratching or touching a lesion.
Acquaint learners with presentation of common dermatologic conditions in their acute phase. Distinguish which acutely presenting characteristics of rashes can be used to make diagnoses. Compare acute and chronic manifestations of disease. Discuss treatment for acute dermatologic skin disease.
The molluscum contagiosum spots have the following characteristics: er, they can grow larger than this, up to 10 to 20 mm. • They are raised bu. on the skin (like a tiny dome), with a shiny surface. • Usually. y are skin coloured, although they can be red or pin.

Molluscum is a common skin infection caused by a virus. What are the symptoms? The molluscum virus produces small, flesh-colored, harmless bumps on the skin, often with a tiny indented center. They can develop anywhere on the body but are most commonly found on the face, trunk and extremities.
