How does cutaneous amebiasis, due to Entamoeba histolytica, present?

Usually the result of direct extension from hepatic or colorectal disease, cutaneous amebiasis presents with serpiginous, warty ulcers of the anogenital area called amebomas. These ulcers may produce extensive tissue loss and predispose to severe secondary bacterial infections. Less common presentations include infection by direct inoculation of the perineum in dysenteric infants wearing diapers and on the penis following anal intercourse with an infected person.
