case_images: fig5
case_images: Histologically, the lesion consisted of granulomatous tissue with multinuclear giant cells and infiltration of lymphocytes and leukocytes (Figure 5(a)). In the granulomatous tissue, a few narrow, curved, eosinophilic structures were observed (Figures 5(b) and 5(c)); therefore, the lesion was diagnosed as a foreign body granuloma.
