Serous borderline tumour is a Muellerian epithelial ovarian tumour with a behaviour that borders on malignant.
It is also known as serous tumour of low malignant potential, abbreviated SLMP.[1][2]
Serous ovarian tumour of low malignant potential redirects here.[2]
General
- Usually benign.
- Require long term follow-up.
Microscopic
Features:[3]
- Cuboidal to columnar epithelium with mild to moderate atypia.
- Non-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 mm2 (area).[3]
- Invasive cells are "pink", i.e. have abundant eosinophilic cytoplasm,[3]; 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.
- Serous cystadenoma of the ovary.
