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。
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.
