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

Patient: Female, 71-year-old Final Diagnosis: Molluscum contagiosum Symptoms: Mass • pain Medication:— Clinical Procedure: Surgical excision Specialty: Dermatology • Infectious Diseases • Pathology • Podiatry OBJECTIVE: Rare disease 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.
