• Asymptomatic nodules, suspected of being nodular melanomas, were subjected to 30 s of direct pressure. All the biopsy-proven nodular melanomas remained unchanged by this procedure. The nodules later proven by biopsy to be angiomas were found to collapse slowly in response to pressure. This test can be used to identify angiomas. It should be employed in the routine clinical examination of lesions suspected of being nodular melanomas.
