Serous borderline tumour is a Muellerian epithelial ovarian tumour with a behaviour that borders on malignant.

Serous borderline tumour
Diagnosis in short

Serous borderline tumour with a micropapillary pattern. H&E stain.

LM cuboidal to columnar epithelium with mild to moderate atypia, no invasion (see below), "sparse" mitoses ,+/-psammoma bodies, +/-micropapillary architecture (often described as a medusa head pattern)
Subtypes serous borderline tumour (SBT) with micropapillary pattern, typical SBT or SBT not otherwise specified
LM DDx serous cystadenoma, serous carcinoma of the ovary, clear cell carcinoma of the ovary
Site ovary, uterine tube - see ovarian tumours

Prevalence uncommon
Prognosis usually benign, need follow-up
Clin. DDx other ovarian tumours (benign and malignant)
Treatment excision, follow-up

It is also known as serous tumour of low malignant potential, abbreviated SLMP.[1][2]

Sign out

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.
