后五副图为常规切片

 有乳腺癌病史，乳腺癌需要除外，但是不是很像，仅从组织像考虑，PEComa、副节瘤优先考虑！

 副节瘤/PEComa．

What a great case!  Abdominal or peritoneal mass are frequent specimen for intraoperative frozen section and very often can be very challenging.  Paraganglioma ( 副节瘤) can occurs in strange locations  other than neck or retroperitoneal.  One paraffin section, it seems to be easier.  On frozen, the tumor cells appear relatively monotonous, can have very atypical cells as well.  The vascular stroma and organoid growth pattern are typical and tumor cells do not have many mitoses and do not have desmoplastic stromal reaction. Thanks.

考虑颈动脉体副神经节瘤，请做S-100.GFAP CGA SYN进一步鉴别。临床确定有转移即为恶性。
