Idiopathic hypereosinophilic syndrome with hepatic sinusoidal obstruction syndrome: A case report and literature review

Figure 3 Pathology of liver and bone puncture of the patient. A and B: Ultrasound-guided liver puncture biopsy suggested hepatic sinusoidal obstruction syndrome. Hepatic lobular structures, hydropic degeneration of hepatocytes, dilated and stagnant lamellar hepatic sinusoids with loss of hepatocytes, residual reticulofibrous scaffolds and insignificant inflammatory cell infiltration were seen (A: magnification 10 ×; B: magnification 40 ×); C and D: Bone marrow aspiration biopsy showed an active proliferation of bone marrow tissue but a significantly higher percentage of eosinophils (23%) with approximately normal morphology (C: magnification 10 ×; D: magnification 40 ×).
