Summary:

Description	Radiopaedia case ID: 44013 Image ID: 20986241 Plane projection: 100x Aux modality: H&E (1) Study description: H&E Images Modality: Pathology System: Obstetrics Findings: The membranes showed no significant acute inflammatory cell infiltrate that would indicate acute chorioamnionitis, however, as you can see from the images above, scattered clusters of intensely eosinophilic cellular material were present on the amniotic surface of the membranes. These clusters displayed varying degrees of degenerative change and appeared mostly amorphous and granular, but where more preserved, appeared to be partly composed of degenerate foetal squames. Careful inspection also revealed hemosiderin deposition (may not be seen in these images). 100x H&E (1): Degenerate material present on the amniotic surface of the membrane. 20x H&E: Low-power view showing slight prominence of eosinophilic material. 40x H&E: No significant inflammation. 100x H&E (2): Normal amnion interspersed with clusters of eosinophilic degenerate material. 200x H&E: Upon closer inspection, you can see variably preserved cells with rounded nuclei and more abundant eosinophilic cytoplasm, consistent with foetal squamous cells (squames).
