Orbital and peri-ocular parffinoma: case series and literature review.

Background: Paraffinoma is a rare and intriguing condition in medicine. In this disorder, an orbital lipogranulomatosis reaction is caused by the penetration of mineral oils (particularly paraffin) into the tissues surrounding the eye.

Methods: In this report, we discuss six cases of paraffinoma affecting the eye socket following sinus surgery. For previous cases literature review, we obtained articles from searching in the PubMed, Scopus, Scholar Google and, Science of Web databases.

Results: After the reporting of 6 paraffinoma cases and literature review, the data related to the disease were categorized into the categories of disease definition, differential diagnosis, clinical manifestation, radiological manifestation, and histopathological diagnosis and treatment methods.

Conclusions: Paraffinoma is a rare and time-delayed diagnosis after various surgeries and therefore may challenge the physician to make the correct diagnosis at first. It is necessary for ophthalmologists to consider this diagnosis in cases of masses around the eyelid and orbit in patients with a history of sinus and nose surgery in other differential diagnoses.
