Verrucous hemangioma is a vascular malformation characterized by vascular spaces in the dermis and subcutaneous tissue with overlying hyperkeratotic, papillomatous epidermis.
Age: Arise at birth or childhood.
Site: Occurs predominantly on the legs.
Clinical presentation: Presents as blue-red, vascular papules, plaques or nodules, which later becomes warty in appearance.
Small satellite nodules may be present.
These lesions do not resolve spontaneously and have a tendency to recur after excision if margins are inadequate.
Microscopic features:
Histopathologic examination shows irregular papillomatosis, acanthosis and hyperkeratosis of the epidermis.
The superficial dermis shows multiple, thin-walled, dilated blood-filled spaces.
Similar spaces are present in the lower dermis and subcutaneous tissue.
Differential diagnosis- Angiokeratoma: Only the superficial blood vessels are dilated. In verrucous hemangioma the vascular spaces are present in the dermis and subcutaneous tissue.
