Eyelid Schwannoma. A Case Report.

In this case report, we describe a 53-year-old woman who presented with a slow-growing lower lid mass in her right eye. On gross examination, a remarkable lower lid bulging was noted. On palpation, a subcutaneous oval-shaped mass with a firm consistency, measuring about 2cm, was noted. The uncorrected visual acuities of the patient were 20/20 (by Snellen chart) bilaterally, and the examinations of the anterior and posterior segments of both eyes were unremarkable. On the orbital Computed Tomography scan of the patient, a solitary and homogenous solid globular mass with the same density of the brain tissue was obvious. The patient underwent surgical excision. Microscopic assessment of the lesion revealed a biphasic hypercellular area (Antoni A) and myxoid hypocellular areas (Antoni B), containing slender cells with tapered ends, interspersed with collagen fibers, consistent with a diagnosis of schwannoma. In addition, some foci of nuclear palisading around the fibrillary process (Verocay bodies) could frequently be found throughout the highly cellular regions. Schwannomas rarely occur in the eyelids, but have clinical and paraclinical indicators which indicate the probable diagnosis. In conclusion, we suggest that eyelid schwannoma be considered as an element of the differential diagnoses list for subcutaneous lesions of the eyelid.

TRAUMA-RELATED ACUTE MACULAR NEURORETINOPATHY. A CASE REPORT.

AIMS: To introduce a case report and review the literature on trauma-related acute macular neuroretinopathy as an unusual etiology of acute macular neuroretinopathy. MATERIAL AND METHODS: A 24-year-old man presented with unilateral paracentral scotoma following non-ocular trauma in a car accident. The relative afferent pupillary defect was negative and the best corrected visual acuities of both eyes were 10/10 (by the Snellen chart scale). RESULTS: Retinoscopy revealed a reduced foveal reflex, along with a small pre-retinal hemorrhage over the mid-pathway of the supranasal arteriole. OCT images showed an obvious ellipsoid zone (EZ) layer disruption in the macula of the left eye. The infrared fundus photograph of the same eye revealed a distinct hyporeflective area involving the macula. On fundus angiography, no macular vascular lesion was detected. The scotoma persisted after 3 months follow-up. CONCLUSION: Non-ocular trauma including head or chest trauma without direct ocular injury accounts for most cases of trauma-related acute macular neuroretinopathy. It is important to distinguish this entity, given that there are also unremarkable findings in the retinal examination of these patients. Indeed, proper clinical suspicion leads to further suitable investigations and impedes other extraordinary images, which are the basic rules in the management of traumatic patients suffering multiple injuries and incurring medical expenses.

ABNORMAL CORNEAL LESION FOLLOWING CATARACT SURGERY; A CORNEAL PYOGENIC GRANULOMA? A CASE REPORT.

BACKGROUND: Description of an abnormal corneal lesion as a complication of a clear corneal incision in cataract surgery. CASE PRESENTATION: A 55-year-old woman presented, complaining of right eye pain and redness for 6 months, which started 1 month after her uncomplicated cataract surgery. On gross examination, the bulbar conjunctiva was hyperemic and a vascularized salmon-pink nodule with a smooth surface was noted over the supratemporal region of the cornea, just anterior to the previous superior corneal incision, with superficial feeder vessels originating from the adjacent conjunctiva toward the lesion. The lesion was removed and histopathological examination revealed an inflammatory tissue containing inflammatory cells and capillaries within a background of fibrotic tissue throughout the lesion. CONCLUSIONS: Reactive fibrovascular nodules are rare corneal lesions following corneal trauma and vascularization, including a clear corneal cataract surgery incision. Ophthalmologists may encounter these lesions during postoperative visits and should be familiar with their appearance and management.
