An orbital masquerade syndrome: a case report.

This report presents the case of a 20-year-old female who presented with features of right panophthalmitis with secondary orbital cellulitis masquerading as an orbital tumour. This presented a diagnostic difficulty to several ophthalmologists. An orbital ultrasound scan revealed an underlying orbital mass, which on histology was discovered to be a well differentiated invasive large cell keratinizing squamous cell carcinoma. This report further emphasizes the value of ultrasound scan in detecting orbital tumours.
