RETROPERITONEAL SOFT TISSUE, RIGHT, CORE BIOPSY: | |||
- SEMINOMA. | |||
</pre> | |||
====Micro==== | |||
The sections show large atypical, discohesive cells with prominent nucleoli, central | |||
nuclei and moderate clear cytoplasm, intermixed with mature lymphocytes. Mitotic | |||
activity is present. | |||
====Small biopsy==== | |||
A mixed germ cell tumour cannot be excluded; given the small quantity of tumour, this | |||
biopsy is at a high risk for having undersampled other tumour components should they be | |||
present. Correlation with serology and consideration of re-biopsy is suggested. | |||
