A Case of Pigmentary Change and Large Verruca in Melanoma Surgery Site

  • 1Department of Dermatology, Eulji University Hospital, Eulji University School of Medicine, Daejeon, Korea


Cutaneous warts are caused by the infection of keratinocytes with human papillomavirus (HPV). Hyperpigmentation is a common condition in which patches of skin become darker than the normal surrounding skin. We report a case of a 56-year-old man who presented with an asymptomatic pinkish and brownish plaque accompanied by progressive pigmentation on the left sole. The lesion was located where the patient had undergone wide excision and skin graft for stage Ib acral lentiginous melanoma three years earlier. Recurrent melanoma (nodular and acral lentiginous type) was suspected, and skin biopsies of the nodular lesion and lentiginous pigmented lesion were performed. The patient was diagnosed with plantar warts with hyperpigmentation by skin biopsy. In this case, damage to the skin barrier at the melanoma site and repeated surgery may have increased the risk of developing verruca and progressive pigmentary changes.
