Toxic granulations, Dohle bodies (dilated ER) , cytoplasmic vacuoles

Nodes are (painful) swollen, gray-red, and engorged. Large reactive germinal centers with numerous mitotic figures. Macrophages often contain particulate debris derived from dead bacteria or necrotic cells.
Acute Nonspecific Lymphadenitis

Tingible body macrophages
4
A person has one of these three things - Rheumatoid arthritis, toxoplasmosis, early HIV.
What type of hyperplasia are these stimuli for?
Three stimuli that cause Follicular Hyperplasia - round, oblong germinal centers surrounded by collar of small resting naive B cells (mantle zone)
5
Name the type of hyperplasia-
1. Dark zone containing proliferating blastlike B cells (centroblasts)
2. Light zone containing B cells with irregular or cleaved nuclear contours
Follicular hyperplasia - a reactive follicle surrounding mantle zone
6
A person has a viral infection (i.e. infectious mono) - what type of hyperplasia is this a stimulus for?
