Eosinophilic granuloma is caused by the excessive growth of which type of cell?

Explanation

Eosinophilic granuloma arises due to the abnormal proliferation of histiocytes, which are a type of immune cell involved in tissue response. Although eosinophils are present in the lesion, they are not the primary proliferating cells. Lymphocytes and fibroblasts do not play a central role in the development of this condition.
