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.
传染性软疣（MC）表现为皮肤色、半球形、脐凹状丘疹或结节，由 MC 病毒引起。它主要发生在学龄儿童，主要影响面部、颈部和身体的中央区域，但很少累及足底。在这里，我们描述了一例 71 岁女性足底跟部 MC 的病例。
一名 71 岁女性因左足跟足底中央有一个 3mm 大小、色淡、珍珠样、圆形、疣状皮损就诊，皮损出现 1 周。切除活检的组织病理学评估显示，数个增生的角化细胞簇内含有呈分叶状、嗜酸性、胞质内包涵体，倒向真皮层，诊断为 MC。
足底跟部 MC 是一种罕见的、不典型的表现，需要与病毒性疣和其他疾病相鉴别。
