What are the symptoms of molluscum contagiosum?

We need to know more about the symptoms of some common diseases in life. For example, the symptoms of skin diseases such as molluscum contagiosum are relatively obvious. There will be obvious papules in the affected skin area. At this time, it is necessary to deal with or treat it in time.

The incubation period is 1 week to 6 months. The typical lesions are papules formed by the proliferation of local epidermal cells. The diameter is 2 to 8 mm. They are single or multiple, round or hemispherical, waxy, and have a concave center. They contain cheesy emboli. The papules are flesh-colored or pink. They are hard in the early stage and soften when mature. Cheesy substances can be squeezed out. Clinically, they can be divided into two types:

①Childhood type: Infection is caused by direct skin contact or transmissible infectious agents. Molluscum warts are seen on the face, trunk and limbs.

② Adult type: It can be sexually transmitted. Molluscum warts are more common on the external genitalia, buttocks, lower abdomen, pubic area and inner thigh area, and occur in the anus during anal sex. Lynch reported 55 such cases, who were soldiers returning to the United States from Vietnam and North Korea who had a history of prostitution in their countries.

Skin lesions can occur on any contact site except the palms and soles, and may also appear on the lips, tongue, buccal mucosa, conjunctiva, etc. Conjunctival lesions may be accompanied by reactive conjunctivitis or keratitis. A few lesions are abnormally large and are called giant molluscum. Some may keratinize and resemble small skin horns, which are called keratotic molluscum. Generally no symptoms.

In cases of HIV infection, the incidence of molluscum contagiosum increases, and the molluscum contagiosum spreads widely and causes large lesions. There are reports of AIDS patients having huge molluscum contagiosum on their faces, which can be easily confused with basal cell epithelioma. In addition, two cases of extensive, acute onset of hundreds of molluscum warts have been reported in patients receiving immunosuppressants. The patient had a history of treatment with prednisolone and methotrexate, and the onset was believed to be related to his immunosuppression.
