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.
