This tumor is similar to the same type of tumors found in other anatomical sites: keratinizing or non-keratinizing atypical squamous cells are found in true tissue fragments, as well as in cell clusters. The center of the lesion is frequently colliquated and necrotic, which results in a fluid aspirate resembling purulent material.

All well known sign of the same lesions in the cervical cytology are seen. The best staining for these lesions seems to be the Papanicolaou stain.

 

Undifferentiated carcinoma

This tumor is malignant in its clinical appearance already: a firm lesion, usually with facial nerve paralysis. The aspirate contains large, highly atypical cells with large, atypical nuclei. They may appear in groups and as single cells as well.
