Cystic squamous cell carcinoma of the orbit

ABSTRACT

Both primary and secondary squamous cell carcinoma (SCC) of the orbit are rare entities, though cystic SCC is even more so. It may provide a significant diagnostic conundrum to oculoplastic surgeons.

We present a case of an 86 year old male with a supero-medial transilluminating cystic lesion of the orbit. There was a preceding history of a moderately differentiated SCC of the cheek, excised 3 months prior. Computed tomography (CT) demonstrated no bone erosion. The cyst was excised aided by fibrin glue. This demonstrated a poorly differentiated cystic SCC with perineural infiltration. The patient elected for palliative aspirations of the cyst and is alive 12 months later.

Cystic SCC of the orbit may present to a number of specialties, including maxillofacial and orbital surgeons. Both diagnosis and management may be challenging. We review common patterns in previous cases and discuss management.
