Oxidised cellulose-based reaction mimicking a suspicious ovarian mass: a case report and a systematic review.

Oxidised regenerated cellulose was introduced 60 years ago to control diffuse bleeding from large surfaces. Although considered safe and effective, foreign body reactions can mimic suspicious masses in several organs. We describe the third case, reported in PubMed, of an oxidised regenerated cellulose-based granuloma mimicking a suspicious ovarian tumour on MRI. During surgery, the diagnosis was suspected by granulomatous tissue and confirmed by pathology. The follow-up after the excision was uneventful. Although a rare complication, physicians should be aware of this presentation and of the recommendation to remove excess Surgicel after the bleeding has stopped.
