The diagnosis is most often made on the basis of clinical appearance. Diagnostic clues include black dots within the warts and/or pinpoint bleeding after paring down the thickened skin. The wart also tends to disturb the natural skin lines and creates a disrupted surface. A biopsy can be used to confirm clinical suspicion, provide proper diagnosis, and help determine if progression to skin cancer, a rare complication, has occurred.
