What is an eosinophilic granuloma?
Eosinophilic granuloma (EG) is a rare, benign tumorlike disorder characterized by clonal proliferation of antigen-presenting mononuclear cells of dendritic origin known as Langerhans cells. It is the most common variant of Langerhans-cell histiocytosis (LCH).
Will eosinophilic granuloma go away on its own?
In many cases, the lesion will spontaneously vanish over time. However, if the itching it causes persists, an affected cat may keep scratching at it, thereby opening it and subjecting the lesion to secondary infection.

Where does eosinophilic granuloma occur in the body?
Eosinophilic granuloma is the most common and the mildest subtype of a group of diseases known as Langerhans cell histiocytosis—disorders in which there is an overproliferation of Langerhans cells. Usually found in the skull bones, eosinophilic granuloma can also arise in other bones, such as the vertebrae, ribs, mandibles, and bones in the limbs.
What kind of disease is eosinophilic granulomatosis with polyangiitis?

What is the role of eosinophils in EGPA?
Among the acquired pathogenetic factors, the exposure to different allergens, infections, vaccinations, drugs, and silica exposure have been involved. Eosinophils are the most characteristic cells in EGPA and different studies have demonstrated their role as effector and immunoregulatory cells.
