Figure 5

(a) An 8-year-old boy with right tibia Langerhans cell histiocytosis. The pathological slice (HEߙ×ߙ200) shows that cells are oval, the nucleus is folded, the chromatin is fine and smooth, the nucleolus is not obvious, the cytoplasm is moderate, slightly eosinophilic, with the background showing the eosinophilic granulocyte, histocyte, multinucleated giant cells, neutrophile granulocytes, and small lymphocytes (HE × 200). (b) MR T2WI with fat suppression showing bone marrow and soft tissue edema around the obvious bone destruction of the right tibia.
