An abscess is a localized collection of PMN's. Here is a microabscess in the myocardium. The irregular dark purple center is a collection of bacteria that are the cause for this abscess.

脓肿是局限化的嗜中性粒细胞感染灶。图示心肌微脓疡。不规则深紫色的中央区聚集了大量细菌，此种细菌引起了脓肿的发生。

This magnetic resonance imaging (MRI) scan of the abdomen in transverse view demonstrates an enlarged spleen with abscesses. The patient had septicemia.

腹部横断面MRI显示脾增大伴有脓肿形成，该病人发生了败血症。

This abscessing bronchopneumonia has numerous areas of raised, lighter tan appearance which are the areas containing the extensive neutrophilic infiltrates.

脓肿化的支气管肺炎可见大量隆起的浅棕色病灶，病灶中有广泛的中性粒细胞渗出。

Microscopically, the extensive neutrophilic exudate of an acute abscessing pneumonia is seen here. Normal tissues are destroyed in the region of the abscess.

急性化脓性肺炎镜下可见广泛的中性粒细胞渗出。脓肿破坏了正常肺组织。

Here is another more focal abscess in the lung. The alveoli in that area have been destroyed.

图示更局限化的肺脓肿，肺泡结构已破坏。

One consequence of acute inflammation is ulceration. This occurs on epithelial surfaces. Here the gastric mucosa has been lost, or ulcerated. A larger ulcer and several adjacent smaller ones with surrounding erythema appear at the left of center.

溃疡形成是急性炎症的结局之一。图示溃疡形成于上皮表面。胃粘膜已经消失或溃烂。图中央左侧可见一个大溃疡和红斑周围几个相邻的小溃疡。

This is a larger ulceration. The cause for the ulceration in this case was an underlying neoplasm.

图示：较大溃疡。这里的溃疡是一种癌前病变。

Below the vocal cords in this larynx are large ulcerations. Such subglottic ulcers are produced with prolonged endotracheal intubation in which the cuff of the endotracheal tube fits too tight. Thus, ulcerations can be produce by mechanical forces. In fact, so-called "pressure ulcers" or "decubitus ulcers" can form on skin over bony prominences in persons who are bedridden for an extended time.

喉声带下方可见大溃疡。这样的声门下溃疡是可由长期的气管内插管造成的，往往见于插管过紧。可以通过机械压迫引起。事实上，我们所说的压疮或褥疮形成于骨较突出的皮肤部位，常见于长期卧床病人。

An esophageal acute ulcer is shown here in which the squamous mucosa has been lost. In the ulcer base are inflammatory cells and fibrin.

图示：食管急性溃疡。

鳞状上皮消失，溃疡底部有炎细胞和纤维蛋白。

Cellular interactions with chronic inflammation are diagrammed.
