Myrmecia
Cutis. 2013 May;91(5):229, 235-236
Myrmecia, named after the bulldog ant because of its clinical resemblance to an ant hill, is a plantar wart caused by human papillomavirus 1 infection. Histologic examination typically reveals an endophytic growth pattern with multiple deep acanthotic extensions of the epidermis that grow inward. Characteristic eosinophilic keratohyalin granules and conspicuous intranuclear inclusions with clear spaces around pyknotic nuclei also can be observed.
