Zellballen pattern (balls of cells) - Images of Paraganglioma 

Dr Sampurna Roy  MD

Paraganglioma is characterized by well defined nests of epithelioid cells. A vascular fibrous stroma separating the nests of cells.   

This is known as Zellballen pattern.

Zellballen meaning "balls of cells" in German.


The cells contain abundant granular cytoplasm. Some large moderately atypical bizarre nuclei are present. This is not an indication of malignancy.
