In the field of medicine, granuloma pyogenicum has quite a recent history. In 1897, Poncet and Dor first brought the matter to the attention of the surgeons in France under the name of botryomycoma, a name that still clings to it in that country. However, the name, granuloma pyogenicum, proposed by Hartzell, is to be preferred. That this condition so long escaped clinical notice is strange, as it frequently causes great anxiety to the patient, and both in its appearance and in its liability to recur after removal bears sufficient symptoms to leave a lasting impression as a clinical entity.
In its simplest form granuloma pyogenicum appears as a small bright red ball of granulation tissue attached to the skin or mucous membrane by a pedicle, and it is frequently attributed to a slight wound. Anatomically, it consists of a mass of granulation tissue more or less
