Chronic inflammation is more difficult to understand, because it is so variable. Seen here is chronic endometritis with lymphocytes and plasma cells in the endometrial stroma. In general, the inflammatory infiltrate of chronic inflammation consists mainly of mononuclear cells: lymphocytes, plasma cells, and macrophages.

由于慢性炎症的多变,因此更难理解。图示:子宫内膜慢性炎症伴淋巴细胞和浆细胞浸润。通常慢性炎症渗出的细胞主要是单核细胞:淋巴细胞、浆细胞和巨噬细胞。

Here is chronic cervicitis. Prolonged acute inflammation or repeated bout of acute inflammation may lead to the presence of more mononuclear cells and chronic inflammation.

图示:慢性子宫颈炎。

长期的急性炎症和急性炎症反复发作都可以导致更多的单核细胞和慢性炎症出现。

Chronic inflammation can go on for a long time. Seen here in the synovium of a patient with rheumatoid arthritis are collections of dark blue lymphocytes.

慢性炎症可持续很长时间。图示风湿性关节炎滑膜见大量深蓝色淋巴细胞。

 

Certain etiologic agents such as viruses are more likely to lead to chronic inflammation, as seen here in the lung of a patient with influenza A. Note also that the inflammatory infiltrates of chronic inflammation are more likely to be interstitial (within tissues) rather than exudative (above surfaces or in spaces) like acute inflammation.

某些病因比如病毒多导致慢性炎症,如图甲型流感病毒感染者肺。慢性炎症更容易浸润组织间质,而急性炎症的渗出主要累及表面及间隙。

You can find both acute and chronic inflammation here. This type of mixed inflammation is typical of repeated or recurrent inflammation. Thus, a diagnosis of "acute and chronic cholecystitis" or "acute and chronic cervicitis" can be made.

也可以见到急性炎症和慢性炎症同时出现的病例。此种混合性炎症主要见于反复发作的炎症,胆囊炎和子宫颈炎可以出现这样的炎症。

Chronic inflammation can be seen in conjunction with some degree of scarring. Here, chronic inflammation of the bronchi has led to dilation and scarring with increased tan to white collagenous tissue.

慢性炎症会与一定程度的瘢痕形成同时发生。图示:支气管慢性炎症致使支气管扩张和瘢痕(深棕色到白色的胶原组织)形成。

Chronic inflammation with destruction of the bronchial wall is seen here. An inflammatory infiltrate extends from the lumen to the left.

图示:慢性炎症致使支气管壁破坏。

An abscess may have elements of chronic inflammation if it persists for some time. Thus, it is possible to have a "chronic abscess" with elements of both acute and chronic inflammation. Seen here in the right middle lung lobe is jus such a chronic abscess.

长时间的脓肿可能是慢性炎症的一个因素。图示:右肺中叶慢性脓肿。

Microscopically, the abscess has a mixture of inflammatory cells, but the wall of the abscess is "organizing" with ingrowth of capillaries and fibroblasts.

镜下,脓肿灶内有大量炎细胞,但脓肿壁由毛细血管和成纤维细胞组成。

Healing of inflammation often involves ingrowth of capillaries and fibroblasts. This forms granulation tissue. Here, an acute myocardial infarction is seen healing. There are numerous capillaries, and collagen is being laid down to form a scar. Non-infarcted myocardium is present at the far left.

炎症的愈合通常有毛细血管和成纤维细胞的参与,它们形成了肉芽组织。图示:急性心肌梗死的愈合。可见大量毛细血管和胶原纤维。左侧是没有发生梗死的心肌。
