Case history
Case history #1
A 5-year-old white boy presents with a history of 2 months of bumps in the left axilla. Initially there was just one lesion; now the parents note that the child has half a dozen lesions. Some of the areas have been inflamed, and the child has pruritus, which keeps him up at night. One of his cousins, with whom he swam, may have such lesions as well. The child also suffers from seasonal allergies.
Case history #2
A sexually active female university student presents complaining of itchy growths on the pubic area and the inner thighs, of 1 month's duration. The patient has been using a condom when she is sexually active with her boyfriend. She had a negative cervical smear 2 months ago. Pearly papules with a central dell can be observed on the pubic area and inner thighs. Some have surrounding erythema and excoriations.
Other presentations
Atypical or uncommon presentations include id reactions and erythema multiforme-like reactions, both of which are hypersensitivity responses. Abscesses form in about 1% as part of the immune response, or due to true bacterial superinfection. Giant molluscum are nodular or tumor-like lesions that lack a central dell and are seen in areas of maceration, such as the intergluteal fold or sole of the foot; this presentation is quite rare. Unusual locations have been noted; the mucosal or conjunctiva lesions look similar to cutaneous lesions, but may have less prominence to the central dell. Occasionally lesions can be seen in newborns or early infancy that are likely to be vertically transmitted from an infected female genital tract.[2]
