Dermpath Diagnosis

Myrmecia

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.
