Intranodular hyperechogenic figures - case 41
Follow-up investigation 2 years later (cytologic picture 5)
Pap-smear, 1000x. The upper 3 cells contain intranuclear round figure. In contrast with pathological inclusions, these are not light and two of them are not round but oval. The presence of a macrophage would be an unusual finding in a simple Hashimoto's thyroiditis and increases the chance being this lesion a pathological nodule.
