It is extremely common among children and may be seen in several children within a family. The lesions may become inflamed if traumatized or infected and sometimes become inflamed spontaneously as they resolve.

The trunk, face, genitalia, and intertriginous areas are the most common sites of infection. Pruritus is an occasional symptom and an eczematous eruption may develop in the area of the molluscum.

Treatment should be individualized to the age and extent of involvement in each patient.

In the cooperative patient, destruction of lesions with curettage or light cryotherapy may be attempted for treatment of limited lesions. Some dermatologists treat this disorder with the office application of topical cantharidin. The child with numerous lesions poses a particular therapeutic challenge.

Two photos of such “giant mollusca” are shown in Figs. 5-5 and 5-6. The diagnosis is usually suggested by the presence of more typical, smaller lesions on adjacent or distant skin surfaces. Note the presence of a central umbilication in Fig. 5-5. Treatment is by surgical removal when possible.

Molluscum in the intergluteal cleft area may appear like “fleshy” skin tags, and upon close examination that can be aided by magnification, a central umbilication can be seen. If the diagnosis is in question, a biopsy would yield the diagnosis.

Large and even small molluscum may scar even without any treatment. Figure 5-8 shows a patient who developed scarring without any treatment given for the molluscum.
