膿瘍
Also known as boil, ulcer
An abscess is a collection of pus that has built up within the tissue of the body, usually caused by bacterial infection. Signs and symptoms of abscesses include redness, pain, warmth, and swelling. The swelling may feel fluid-filled when pressed. The area of redness often extends beyond the swelling. Carbuncles and boils are types of abscess that often involve hair follicles, with carbuncles being larger. A cyst is related to an abscess, but it contains a material other than pus, and a cyst has a clearly defined wall. Abscesses can also form internally on internal organs and after surgery.
AI overview
An abscess is a pocket of pus that forms in your body tissue, usually because of a bacterial infection, and typically causes redness, pain, warmth, and swelling in the affected area. They matter because they can occur anywhere in the body—including on your skin or inside your organs—and require proper medical attention to prevent complications.

膿瘍（のうよう）とは、化膿性炎症が生体組織内に限局した場合で崩壊した好中球に由来した分解酵素により中心部から融解して、膿を満たした空洞を形成した状態をいう。また、膿瘍形成には、持続的な激しい炎症性刺激が前提条件となっている。 皮下、肝臓、脳、肺、腎臓に見られる。また、皮膚や口腔粘膜の比較的表層（上皮内や上皮直下）に限局した膿瘍は膿疱という。 既存の体腔内に膿が貯留する場合は蓄膿と呼ばれる。 深部に形成された膿瘍ではが形成され膿が外部へと排出される。
