Corneal perforation and rare primary adenocarcinoma of the lacrimal gland: A case report
Abstract
Rationale: Primary adenocarcinoma of the lacrimal gland is rare, and its presentation as corneal perforation is even rarer. Corneal perforation is an ocular emergency that warrants urgent ophthalmic surgery, yet complete staging of lacrimal gland tumor pre-operatively is essential for optimal oncological management. Patient’s concerns: A 57-year-old man presented with left eye pain was found to have left eye proptosis and fleshy tissue mass around the eyeball. Uveal tissue was prolapsing over the perforated keratitis cornea, and the eye was full of discharge. Diagnosis: Bedside ultrasound B-scan confirmed vitreous haze, and emergency contrast computed tomography (CT) revealed soft tissue density mass (>40 mm) molding around the left globe and optic nerve without any rim enhancing abscess. Left exogenous endophthalmitis from exposure keratopathy secondary to proptosis caused by the bulky lacrimal tumor located in the confined orbital cone was diagnosed. Interventions: Emergency enucleation surgery of the left eyeball was done for this painful blind eye to control the infection from spreading. Orbital walls were biopsied intra-operatively, and tumor staging was completed by positron emission tomography- CT scan and magnetic resonance imaging. Without evidence of metastasis, left orbital exenteration was followed by adjuvant orbital chemoradiotherapy for the sake of close proximity of resection margin. Outcomes: Left exenterated orbit was fully epithelialized at around 2 months, and there was no recurrence of the disease up to present at the 1 year follow-up. Lessons: Thorough workup on the staging of the disease to minimize the number of operations for oncological patients is always a top priority, yet it may not always be possible as in our case presenting with corneal perforation.
