定义
This condition is caused by the molluscum contagiosum virus, a ubiquitous poxvirus that escapes immune destruction for months to years. Lesions are cutaneous (less commonly mucosal). They appear as pearl-like, smooth papules, which are umbilicated. Molluscum lesions display characteristic intracytoplasmic inclusion bodies (referred to as molluscum bodies or Henderson-Patterson bodies) on histology. Lesions are generally caused via skin-to-skin or fomite contact in children, and often by sexual transmission in adults.[1][Figure caption and citation for the preceding image starts]: Extensive molluscum lesions on the flank of a young child; lesions are flesh to pearly colored with central dellsFrom the collection of Dr Nanette Silverberg [Citation ends].
