Squamous carcinoma of the ovary.

Squamous ovarian cancer (SOC) represents a (very) rare subtype of ovarian cancer. The lack of evidence on which to base management presents significant challenges. The small number of patients prohibits randomised studies to establish level 1 evidence, and no non-randomised studies or prospective series have been reported. Here, we present a review of the available literature on squamous ovarian cancer and explore some lessons learnt from squamous cancers originating from other primary sites to see if these can be applied to SOC.
