An inflamed, tender swelling of a lymph node, especially in the area of the armpit or groin, that is characteristic of certain infections, such as bubonic plague and syphilis.

[Middle English, from Late Latin būbō, būbōn-, from Greek boubōn, groin, swelling.]

When a Los Angeles woman was diagnosed with bubonic plague (the disease is extremely rare and even more so in urban areas), attention was drawn to the amusingly named but nevertheless repugnant bubo:

"Bubonic plague affects the lymph nodes... Within three to seven days of exposure to the bacteria, flu-like symptoms will develop such as fever, headache, chills, weakness, and swollen, tender lymph glands (called buboes-hence the name bubonic)."
