Retinoma — the first identified case in Jordan

Retinoma (or retinocytoma) is a rare benign intraocular tumor with characteristic features and can be diagnosed clinically. In this article, we present a case report and a review of literature about retinoma. The case is about an incidentally diagnosed retinoma in an asymptomatic young female who presented for vision checkup and was found to have an intraocular translucent-grey, elevated mass extending into the vitreous cavity from the retina with the characteristic features of retinoma. The main differential diagnosis included retinoblastoma and astrocytic hamartoma. The mass showed no growth over a period of 6 months of follow up with colored fundus photography and ultrasound. This case is, to the best of our knowledge, the first case of retinoma diagnosed in Jordan

Familial Retinoblastoma: Raised Awareness Improves Early Diagnosis and Outcome

Purpose. To study the impact of awareness of retinoblastoma in the affected families on the management and outcome of familial retinoblastoma patients. Methods and Materials. This is a retrospective, clinical case series of 44 patients with familial retinoblastoma. Collected data included patient’s demographics, laterality, family history, age at diagnosis, presenting signs, treatment modalities, tumor stage, eye salvage rate, metastasis, and mortality. Results. Out of 200 retinoblastoma patients in our registry, 44 (22%) patients were familial, 18 were probands, and 26 were second, third, or fourth affected family members. There were 76 affected eyes: 31 eyes of probands and 45 eyes of the other affected family members. Among probands, all patients (100%) had at least one eye enucleated: 58% (18 eyes) of the affected eyes were enucleated and 32% (10 eyes) of the affected eyes were radiated. On the other hand, among the nonprobands, only 20% had one eye enucleated, and only 4 eyes (9%) received radiation. The eye salvage rate was significantly higher in the nonprobands than in the probands in this series (p=0.00206). Patients diagnosed by screening (38%) had excellent visual outcome, and both eyes were salvaged. Conclusion. Awareness of families of the possibility of retinoblastoma and adequate screening led to a significantly higher rate of eye salvage in patients with familial retinoblastoma

Kinematic Gait Analysis for School age Children in Capital Governorate at Kuwait

Background: pediatric gait evaluation is considered an important element of children’s physical assessment and reflects their quality of life, health status and physical functions. Purpose: analyze kinematic gait parameters in normal school age children in Capital governorate at Kuwait and compare these findings with normal standard values Methods: Sixty normal healthy children from different schools at capital governorate in Kuwait were selected. Their ages were ranged from 6 to 12 years of both genders with normal Body mass index (BMI). They were assigned into three groups, group (A) 6 -8 years, group (B) 8 -10 years where group (C) 10 -12 years. All children underwent physical evaluations that were carried out for eligibility of selection. Then they scheduled for gait analysis using bioengineering BTS- FREEEMG 300 gait lab. The measured Kinematic gait parameters included temporal (stride time, stance time, swing time, stance phase, swing phase double support phase, velocity, and cadence), and spatial (stride length, step length, step width). Results: there were significant statistical difference between Kuwait children and normal standard values in some parameters as stride time for group A and group B, stance phase for group B, velocity for group A, B, and C, cadence for group C, step length for group A, B, and C and step width for group A and C. Conclusion: It can be concluded that kinematics gait analysis of Kuwait school age children at the capital governorate resembles and consistent with normal standard values ,except some values that differ significantly from the normal standard values

Characteristics, management, and outcome of ocular medulloepithelioma: systematic review of literature and case report

Background: Ocular medulloepithelioma (OM) is a rare ocular malignancy. This is a report of a rare case of medulloepithelioma that was misdiagnosed as retinoblastoma. Material and methods: A case report and review of published, peer-reviewed, English language literature reporting on ocular medulloepithelioma. Results: A seven-year-old girl presented with a white mass in the anterior chamber of her left eye. The initial diagnosis was retinoblastoma with anterior chamber invasion, and therefore it was enucleated. Microscopy showed a cellular tumour composed of malignant primitive cells forming sheets, rosettes, and tubular structures. Based on the presence of prominent pleomorphism the tumour was diagnosed as malignant teratoid medulloepithelioma. At last date of follow-up three years after enucleation, the patient was alive without metastasis. A systematic review of literature, analysed 177 cases of OM. The tumour was localised in the ciliary body in 134 (92%) cases, and 26 (23%) cases had extraocular extension. Primary management was enucleation in 84 (55%) cases, tumour resection in 32 (21%) cases, and radiation therapy in 20 (13%) cases. Histopathology disclosed benign features in 36 (22%) eyes, malignant features in 124 (78%) eyes, teratoid features in 72 (59%), and non-teratoid features in 51 (41%) eyes. At a mean follow-up of five years, 14 (8%) patients had metastasis, and six (6%) patients were dead. Conclusions: Ocular medulloepithelioma most commonly affects children. The most common type is the malignantteratoid type, but it has a favourable prognosis, and distant metastasis and mortality are relatively rare, at 8%and 6%, respectively

Simultaneous choroidal melanoma and renal cell carcinoma in middle-aged patient

Background: Although rare, choroid melanoma is the most common intraocular malignancy amongst adults. Similarly, renal cell carcinoma (RCC) is another rare malignancy that counts for 2–3 percent of all adult malignancies. Second primary cancers are not uncommon, even though they occur less frequently than primary cancers. Case presentation: We present a rare choroidal melanoma case in a 55-year-old adult who presented with a one-month history of the painless gradual decrease of vision. His investigations revealed a clinical diagnosis of large choroid melanoma, and upon metastatic workup, he was incidentally found to have synchronous RCC. Both malignancies were treated surgically (and the pathology confirmed the clinical diagnosis of choroidal melanoma and RCC). The patient was free of metastatic or recurrent disease at 12 months follow-up

Metastatic unilateral retinoblastoma to the contralateral orbital optic nerve presenting with optic disc edema

Retinoblastoma (Rb) is a malignant eye tumor that poses a significant risk of mortality once metastasized. We present the case of a 30-month-old girl with left-sided Rb who underwent primary enucleation with pathology-confirmed diagnosis without high-risk pathologic features. Therefore she did not receive adjuvant chemotherapy. Six months later, the patient developed skull bone and bone marrow metastasis, which were treated with systemic chemotherapy, excision of bone metastasis, focal radiation treatment to the site of osseous metastasis, and bone marrow transplantation. Follow-up for two years was unremarkable until she presented with vision loss in the remaining contralateral eye. Ophthalmic examination revealed severe optic disc edema without intraocular masses, initially thought to be optic neuritis. However, the patient did not respond to steroids, and the initial cerebrospinal fluid (CSF) analysis was negative. This was repeated based on high clinical suspicion of metastasis, revealing only a few malignant cells. The presentation and appearance of the optic nerve were considered metastasis-related and treated with radiation therapy, which resulted in dramatic clinical and radiological improvement. Unfortunately, a few weeks later, the patient developed lower limb weakness, and imaging showed diffuse leptomeningeal metastasis, confirmed by CSF findings. This case represents the first documented isolated contralateral optic nerve metastasis in Rb

Causes of death and survival analysis for patients with retinoblastoma in Jordan

PurposeTo analyze causes and prognostic factors for death among Retinoblastoma (Rb) patients treated at a single specialized tertiary cancer center in Jordan.MethodsWe reviewed the mortality causes for all Rb patients who have been treated at the King Hussein Cancer Center between 2003 and 2019 and were followed for at least 3 years after diagnosis. The main outcome measures included demographics, laterality, tumor stage, treatment modalities, metastasis, survival, and causes of death.ResultsTwenty-four (5%) of the 478 patients died from retinoblastoma and 5-year survival was 94%. The mean age at diagnosis was 15 months (median, 18 months; range, 4–38 months); eight (33%) received diagnoses within the first year of life. Eleven (46%) were boys, 16 (67%) had bilateral disease, and 3 (13%) had a positive family history. The stage for the worst eye was C for 1 (4%) patient, D in 6 (25%) patients, and E (T3) in 15 (63%) patients. Two patients had extraocular Rb at diagnosis, and four of the patients who had intraocular Rb at diagnosis refused treatment and then came back with extraocular Rb. In total, extraocular disease was encountered in six eyes (six patients). After a 120-month median follow-up period, 24 patients (5%) died of second neoplasms (n = 3) or metastases (n = 21). Significant predictive factors for metastasis and death included advanced IIRC tumor stage (p < 0.0001), the presence of high-risk pathological features in the enucleated eyes (p = 0.013), parental refusal of the recommended primary treatment plan (p < 0.0001), and extraocular extension (p < 0.0001).ConclusionThe 5-year survival rates of Rb patients in Jordan are as high as those in high-income countries. However, 5% are still dying from metastatic disease, prompting the need for awareness campaigns to educate the public about the high cure rates and to prevent treatment abandonment

Retinoblastoma seeds: Impact on American Joint Committee on Cancer clinical staging

Aim To investigate whether the American Joint Committee on Cancer (AJCC) clinical category cT2b needs to be subclassified by the type and distribution of retinoblastoma (RB) seeding. Methods Multicentre, international registry-based data were collected from RB centres enrolled between January 2001 and December 2013. 1054 RB eyes with vitreous or subretinal seeds from 18 ophthalmic oncology centres, in 13 countries within six continents were analysed. Local treatment failure was defined as the use of secondary enucleation or external beam radiation therapy (EBRT) and was estimated with the Kaplan-Meier method. Results Clinical category cT2b included 1054 eyes. Median age at presentation was 16.0 months. Of these, 428 (40.6%) eyes were salvaged, and 430 (40.8%) were treated with primary and 196 (18.6%) with secondary enucleation. Of the 592 eyes that had complete data for globe salvage analysis, the distribution of seeds was focal in 143 (24.2%) and diffuse in 449 (75.8%). The 5-year Kaplan-Meier cumulative globe-salvage (without EBRT) was 78% and 49% for eyes with focal and diffuse RB seeding, respectively. Cox proportional hazards regression analysis confirmed a higher local treatment failure risk with diffuse seeds as compared with focal seeds (hazard rate: 2.8; p<0.001). There was insufficient evidence to prove or disprove an association between vitreous seed type and local treatment failure risk(p=0.06). Conclusion This international, multicentre, registry-based analysis of RB eyes affirmed that eyes with diffuse intraocular distribution of RB seeds at diagnosis had a higher risk of local treatment failure when compared with focal seeds. Subclassification of AJCC RB category cT2b into focal vs diffuse seeds will improve prognostication for eye salvage.Fil: Tomar, Ankit Singh.
