Aschoff bodies in Rheumatic heart disease show all of the following features, except -
Anitschkow cells
Epithelioid cells
Giant cells
Fibrinoid necrosis
Aschoff body is the microscopic lesion that is diagnostic of rheumatic fever. It is characterized by an area of granular fibrinoid necrosis surrounded by :-

a. Histiocytes
b. Lymphocytes
c. Plasma cells
d. Fibroblasts
e. Collagen
f. Anitschkow cells -
Anitschkow cells are actually histiocytes which have become multinucleated to form Aschoff giant cells.

Aschoff bodies can occur in any layer* of the heart but they are most commonly seen in subendocardial region* and the myocardial interstitium.
