A Case of Verrucous Hyperplasia with Lymphedema of Leg Amputation Stump / 대한피부과학회지

ABSTRACT

Verrucous hyperplasia appears as multiple, warty, coalescent papules arising on the distal portion of amputation stump skin, yet it displays no histological evidence of viral warts. It occurs when the chronic pressure of a poor prosthetic fit disrupts vascular and lymphatic channels, subsequently causing chronic tissue edema. We report a case of 30 year old male, with 15 year history of wearing below-the-knee prosthesis, who presented with a verrucous papule that arose at his amputation site. Histopathological findings showed hyperkeratosis, acanthosis, superficial dermal edema and dilated thick vessles oriented vertical to the skin surface. Verrucous hyperplasia with lymphedema was diagnosed on the basis of clinical and histological findings.
