Infectious Diseases and Microbiology - Molluscum Contagiosum ( Molluscum contagiosum virus ( MCV))1/21/2024 ![]() Infectious Diseases and Microbiology - Molluscum Contagiosum ( Molluscum contagiosum virus ( MCV)) Molluscum contagiosum is a viral skin infection. Molluscum contagiosum is a viral infection caused by the poxvirus known as molluscum contagiosum virus (MCV). MCV is transmitted through direct physical touch. Sexual transmission is possible for genital MCV lesions. Molluscum contagiosum is characterized by the presence of harmless, elevated skin lesions that have a pearly, flesh-colored appearance. These nodules are typically umbilicated and do not cause any systemic symptoms. MCV lesions are asymptomatic and spontaneously resolve over time.MCV invades epidermal cells and creates a specific type of skin lesion characterized by a central depression. Due to its superficial position, MCV elicits a modest inflammatory or immunological response. The diagnosis of MCV can be established by histologically identifying eosinophilic cytoplasmic inclusions (molluscum bodies) in skin lesion biopsy samples. MCV does not have a targeted antiviral treatment available. Treatment methods include curettage, cryotherapy, or the use of topical medications. Currently, there is no available vaccination to provide protection against MCV infection.
