To describe an unusual case of retinoblastoma in adult Saudi. A 21-year-old Saudi male developed acute unilateral visual loss due to a large intraocular lesion in his left eye. Within five days of presentation, the tumor enlarged rapidly causing angle closure glaucoma and orbital cellulitis like picture. The patient underwent enucleation and the histopathology specimen confirmed the presence of an undifferentiated type tumor cell that was consistent with retinoblastoma with choroidal and optic nerve invasion. Retinoblastoma should be considered in the differential diagnosis of an intraocular mass in adults. To the best of our knowledge, this is the first reported case of an adult presentation of retinoblastoma in Saudi patient.

  Introduction Top

Retinoblastoma is the most common intraocular malignancy in childhood and infancy. Approximately 90% of cases are diagnosed before five years of age.[1] Adult-onset retinoblastoma is extremely rare and hence is usually not considered in the top differential diagnosis of adults presenting with retinal or intraocular lesions. As per literature review, only 45 cases was reported till date[2],[3],[4],[5],[6] and the oldest report was presented in 1919 from a 20-year-old white girl.[2] The oldest reported age of RB in the Saudi population was 12years.[7] We present a histopathologically proven case of retinoblastoma in an adult Saudi male. This is likely the oldest presentation of retinoblastoma among Saudi population published to date.

  Case Report Top

A 21-year-old healthy male presented to the emergency department with a history of acute painless visual loss in his left eye for one month duration that was associated with redness. The patient was using 1% prednisolone acetate eye drops prescribed elsewhere. On examination, visual acuity was 20/20 in the right eye and light perception in the left eye. The right eye was unremarkable. On examination, intraocular pressure (IOP) in the left eye was 16mmHg, the cornea was clear, the anterior chamber did not show any active cells, the lens was clear and displaced. Fundus examination indicated a whitish reflex with a large intraocular mass pushing the iris-lens diaphragm anteriorly and superiorly [Figure 1]a,[Figure 1]b,[Figure 1]c. B-Scan ultrasonography revealed a large Choroidal lesion superiorly [Figure 1]d. This lesion measured 25.1mm at the base and 15.0mm in depth with a secondary total retinal detachment. A-scan ultrasonography indicated a lesion that was 16.8mm in depth and low internal reflectivity with minimal vascularity. Magnetic resonance imaging (3 Tesla) of the globe and brain is presented in [Figure 1]e. The differential diagnosis included amelanotic melanoma, Metastatic carcinoma and intraocular infection. On the following day the patient developed severe pain in the left eye secondary to elevated IOP of 60mmHg with no light perception vision. The anterior chamber was shallow and the patient was admitted and managed with antiglaucoma medications. Over the subsequent two days the patient developed cells resembling tumor cells in the anterior chamber with severe conjunctival chemosis lid edema with restriction extra ocular muscle movement which clinically was consistent with orbital cellulites [Figure 2]a and [Figure 2]b. Laboratory tests ruled out any infection. A repeated ultrasound showed extension of medium low reflective choroidal mass with markedly thickened sclera and T-sign posteriorly. There was suspicion of early sclera perforation, based on that the patient underwent urgent enucleation with silicone ball implantation. The results of histopathology specimen confirmed the presence of an undifferentiating cell type consistent with retinoblastoma with choroidal and optic nerve invasion [Figure 3]c,[Figure 3]d,[Figure 3]e,[Figure 3]f,[Figure 3]g. The patient was referred to oncology for chemotherapy and radiotherapy with the possibility of orbital metastasis.
Figure 1: (a) SLE picture showed quite eye, anterior chamber did not show any active cells, the lens was clear and subluxated; (b and c) fundus showed a whitish reflex with large intraocular mass that pushing the iris lens diaphragm forward superiorly; (d) B-san showed large choroidal lesion detected superiorly. This lesion measured 25.1 mm in base and 15.0 mm in depth by transverse there was secondary total retinal detachment; (e) MR Imaged at 3Tesla.

Upper right and middle left; axial T2-weighted fat suppressed image shows a large hypo-intense mass at the postero-inferior left globe (black arrow) showed numerous punctate foci of signal loss presumptively tiny calcification with the retinal leaves are elevated with subretinal fluid of hemorrhagic nature (white arrow) with marked narrowing of the anterior chamber (white dashed arrow). Middle right; ADC map shows lower signal measured ADC of 0. 79 10–3 mm2/s at the central mass markedly lower values with sharp contrast between the cellular mass and the subretinal exudate at the same section (black dashed arrow) with some degree of globe warping. Lower left, lower right; axial and sagittal fat suppressed contrast-enhanced T1-weighted image shows faint, contrast enhancement as plaque-like area (solid white arrow)

  Discussion Top

The findings of the clinical and diagnostic image tests of this case are compatible with previous reports. The most common causes of secondary glaucoma in retinoblastoma is iris neovascularization (NVI) followed by pupillary block secondary to anterior displacement of the lens-iris diaphragm and tumor seeding of the anterior chamber.[8] We believe that our patient had sudden increased intraocular pressure due to rapid growth of the tumor that caused anterior displacement of the lens-iris diaphragm with elements of pupillary block in addition to tumor seeding in the anterior chamber. Our case developed tumor related orbital cellulis. In fact, orbital cellulitis associated with retinoblastoma is uncommon and is characterized by noninfectious inflammation of the periorbital structures. The underlying mechanism is thought to be necrosis of the intraocular tumor, leading to intraocular and periorbital inflammation.[9],[10] Histopathology of the enucleated specimen in the majority of the reported adult retinoblastoma cases had differentiated, showing Flexner-Winter Steiner rosettes.[6],[11] In our case, the tumor was classified as undifferentiated retinoblastoma with no rosettes and fleurettes with massive necrosis and hemorrhage. In conclusion, although retinoblastoma in general is rare among adult population, it should be considered in the differential diagnosis of sudden onset intraocular mass with unusual clinical presentation in Saudi adults.
