Case Report: Molluscum Contagiosum and Verruca Vulgaris in a 7-Year-Old Female | Village Dermatology Katy & Houston, TX
Introduction
Skin infections caused by viruses are common in children, with molluscum contagiosum and warts (verruca vulgaris) among the most frequent. These lesions may persist for years, spread to other areas, and cause parental concern. At Village Dermatology in Katy and Houston, Texas, we offer safe and effective treatments, including cantharidin therapy, to help children achieve clear skin.
Patient Presentation
The patient, a 7-year-old female, presented with:
Growing warts on the right knee, present for years
Shiny bumps on the abdomen and buttocks, suspected to be molluscum contagiosum
She had not received prior treatment for these lesions.
Examination
A focused dermatologic exam revealed:
Verruca vulgaris (common warts): cauliflower-like papules on the right knee
Molluscum contagiosum: pink, shiny, dome-shaped papules with central umbilication on the abdomen, right buttock, and left buttock
The patient was otherwise well-nourished, alert, and in no acute distress. A dermatoscope was used to confirm clinical features.
