Immunophenotypical assessment supports that post‐chemotherapy glandular tumours of germ cell origin straddle between glandular yolk sac tumour and 'somatic‐type' adenocarcinoma.

This article discusses the immunophenotypical assessment of post-chemotherapy glandular tumors of germ cell origin. These tumors can exhibit a range of morphologies, including sarcomatoid and glandular tumors. Historically, these malignancies were thought to arise from postpubertal-type teratoma, but recent studies suggest that adenocarcinomas may arise from postpubertal-type yolk sac tumors (YST). The study found that the expression of transcription factors FOXA2 and HNF1β can help elucidate the origin of these tumors within the spectrum of glandular YST and somatic-type adenocarcinomas (STAs). Further research is needed to fully understand the development and progression of these tumors. [Extracted from the article]
