Laboratory Findings
- Laboratory studies usually are not indicated in children with molluscum contagiosum. Sexually active adolescents and adults with genital lesions should be evaluated for the presence of other sexually transmitted diseases.
- Patients with extensive lesions should be tested for human immunodeficiency virus (HIV) infection, and the possibility of other immune system disorders should also be considered.
- Electron microscopic evaluation of tissue is not a part of routine diagnosis procedure, but if done it may show:
- Typical brick-shaped poxvirus particles inside the infected tissue which is highly specific for diagnosis.
- Electron microscopy can also identify infected cells that appear normal on light microscopy
