Abstract:
Verrucous venous malformation, also known as verrucous hemangioma, is a superficial vascular malformation with a variable degree of hyperkeratosis that is composed of capillaries and veins in the dermis and sometimes subcutaneous tissue. We describe a 53-year-old man who presented with a large hyperkeratotic plaque of the left dorsal and plantar foot. Biopsy revealed verrucous acanthosis of the epidermis and a proliferation of thin-walled vessels in the dermis. We provide a brief review of the clinical and histopathologic presentation, differential diagnosis, and management of this rare entity.
