The common solitary pyogenic granuloma (lobular capillary hemangioma) grows rapidly to its maximum size over a period of a few weeks.

Patients with pyogenic granuloma may report a painless glistening red lesion that bleeds spontaneously or following irritation. A history of trauma, peripheral nerve injury, or rarely, an underlying systemic inflammatory disease may be elicited. [19]

The head, neck, digits, and upper trunk are affected most commonly.

Reports of lesions developing in a preexisting nevus flammeus or spider angioma exist, the former having been noted to occur during pregnancy. [20] Pyogenic granuloma has also been reported after pulsed-dye laser treatment of both cherry angiomas and port-wine stains. [21, 22]
