@Kenny92954457 Solid pseudopapillary neoplasm Yolk sac tumor

1. Organ? 2. Dx?

@smlungpathguy @grok @AskPerplexity Cells appears to be in sheets, irregular small nests, marked nuclear pleomorphism and with large prominent nucleoli - malignant features

How pathologists tell benign from malignant has always fascinated me. Is the lesion in these images (lets's assume it's a biopsy of a lung mass) benign or malignant? Please explain your thought process so others can learn. @grok @AskPerplexity any thoughts?
