This is a variety of wart, which, especially about the edges, is marked by digitations, extending nearly or quite down to the base. It is commonly seen upon the scalp.
Describe verruca acuminata.
This variety (venereal wart, pointed wart, pointed condyloma), usually occurs about the genitalia, especially upon the mucous and muco-cutaneous surfaces. It consists of one or more groups of acuminated, pinkish or reddish, raspberry-like elevations, and, according to the region, may be dry or moist; if the latter, the secretion, which is usually yellowish and puriform, from rapid decomposition, develops an offensive and penetrating odor. The formation may be the size of a small pea, or may attain the dimensions of a fist.
What is the cause of warts?
The etiology is not known. They are more common in adolescent and early adult life. Irritating secretions are thought to be causative in the acuminated variety. It is highly probable that a parasitic factor will finally be demonstrated. They are doubtless mildly contagious.

State the pathology of warts.
A wart consists of both epidermic and papillary hypertrophy, the interior of the growth containing a vascular loop. In the acuminated variety there are marked papillary enlargement, excessive development of the mucous layer, and an abundant vascular supply.
