Carcinoma-in-situ (erythematous)

Image Description
Carcinoma-in-situ Carcinoma in situ of the left lateral surface of the tongue. The lesion is a mixed erythematous and white plaque.
Carcinoma-in-situ In this example there are disorderly, hyperchromatic squamous cells throughout the thickness of the epithelium.
Carcinoma-in-situ The arrows point to atypical, multipolar mitotic figures; these are commonly seen in both CA-in-situ and invasive SqCA. We speak of CA-in-situ when the dysplastic keratinocytes remain localized within the epithium.
