Study on 100 consecutive patients with thyroid nodule - case 042

Follow-up examination one year later (cytologic picture 7)

Pap-smear, 1000x.   Pap staining has one important disadvantage to Wright-Giemsa staining: the cytoplasmic fine granulation is more difficult to judge and therefore the identification of oxyphilic metaplasia is frequently not possible. Nevertheless, the cells presented in this image present probably oxyphilic changes.
