Molluscum Contagiosum on the Sole of the Foot in an Elderly Patient: A Case Report.

BACKGROUND Molluscum contagiosum (MC) presents as skin-colored, dome-shaped, umbilicated papules or nodules on the skin and is caused by the MC virus. It predominantly occurs in school-aged children and mainly affects the face, neck, and central regions of the body but, rarely, the soles of feet are affected. Here, we describe the case of a 71-year-old woman with MC on the plantar heel. CASE REPORT A 71-year-old woman presented with a 3-mm, pale, pearly, round, verrucoid lesion along the plantar central aspect of the left heel, present for 1 week. Histopathological evaluation of the excisional biopsy revealed several clusters of hyperplastic keratinocytes containing lobulated, eosinophilic, intracytoplasmic inclusion bodies inverted into the dermal layer, which was diagnosed as MC. CONCLUSIONS MC on the plantar heel is a rare, atypical presentation that needs to be differentiated from viral warts and other diseases.
