Gumma is a term used to describe a type of soft, tumor-like growth that can occur in various tissues of the body, often as a result of syphilis. These growths are typically painless and can develop in areas such as the skin, bones, or internal organs. Gumma is a manifestation of late-stage syphilis, which is a sexually transmitted infection caused by the bacterium Treponema pallidum. The presence of gumma indicates that the infection has progressed and may require medical treatment. Diagnosis usually involves a physical examination and may include blood tests to confirm syphilis infection. Treatment typically involves antibiotics, which can help manage the infection and reduce the size of the gumma.
