especially of a dense fibrous tissue capsule enclosing inflammatory and necrotic 
areas in which peculiar, large, swollen lipoid cells with multiple inclusions in 
their protoplasm are situated, distinguish and separate at least one form of these 
nodules very strikingly from that one of onchocereal origin. Dr. 8. B. Wolbach,

the fibrous tissue surrounding the areas of necrosis containing these lipoid or 
foam cells resembling xanthoma cells.
