{{Main|Serous borderline tumour}}
===General===
*Usually benign.
*Require long term follow-up.
 
===Microscopic===
Features:<ref name=Ref_GP399>{{Ref GP|399}}</ref>
*Cuboidal to columnar epithelium with mild to moderate atypia.
*No invasive.
*"Sparse" mitoses.
*+/-[[Psammoma bodies]].
*+/-Micropapillary architecture - often described as a ''medusa head'' pattern.
 
DDx:
*[[Serous carcinoma of the ovary]] - focus a with stromal invasion >5mm (linear measurement) ''or'' > 10 mm<sup>2</sup> (area).<ref name=Ref_GP399>{{Ref GP|399}}</ref>
**Invasive cells are "pink", i.e. have abundant eosinophilic cytoplasm,<ref name=Ref_GP399/>; also, cells usu. large (~2-3x size of non-invasive component), and typically have an enlarged nucleus (~2x non-invasive component).
*[[Clear cell carcinoma of the ovary]] - classically associated with [[endometriosis]], have simpler, smaller papillae without branching.

*Micropapillary serous borderline tumour.
*Typical serous borderline tumour (SBOT).
 
===Sign out===
<pre>
Cyst and Right Fallopian Tube, Excision:
    - SEROUS BORDERLINE TUMOUR with micropapillary architecture, see comment.
    - Fallopian tube within normal limits.
    - NEGATIVE for evidence of invasion.
 
Comment:
The lesion appears to be confined to a cystic structure.
