A Case of Verrucous Hyperplasia with Lymphedema at the Distal Stump of a Below-the-knee Amputee / 대한피부과학회지

ABSTRACT

Verrucous hyperplasia of the distal stump skin is a rare condition which shows multiple, irregular warty papules and plaques but histologically no evidence of viral warts. It has been suggested that verrucous hyperplasia results from persistent stump edema, usually when the distal stump is unsupported in the prosthesis socket. We present a 53-year-old male who showed verrucous plaques on the distal stump skin and also showed edematous change with oozing. He has been wearing a below-the-knee prosthesis for 35 years since a traumatic amputation and has not changed the prosthesis for 30 years. Histopathological findings showed hyperkeratosis, parakeratosis, acanthosis, papillomatosis, dermal edema, fibrosis, dermal vessel proliferation and dilatation. He was diagnosed as having verrucous hyperplasia with lymphedema by clinical and histopathological findings.
