Botryomycoma

pyogenic granuloma, a benign, quickly developing tumor of skin or mucosa, suspended on a peduncle. Externally, botryomycoma resembles a mushroom or a bunch of grapes; it is soft, bluish-red, and bleeds easily. It is caused by trauma, excoriation, a splinter, a puncture, or infection with pyogenic bacteria (principally staphylococci). Botryomycoma is usually located on open parts of the body—for example, fingers, lips, cheeks, or forehead. It grows quickly; its surface may ulcerate and then be covered with a scab. Treatment is surgical (electrocoagulation).
