Background: In March 2020, WHO announced Coronavirus Disease 2019 (COVID-19) outbreak a global pandemic. During this pandemic, patients with sickle cell disease (SCD) have been placed in the “high-risk” category of the population. Although there are numerous publications describing COVID-19 in adult patients, pediatric data are still limited. Observation: Herein, we report case series of 5 sickle cell disease Omani children who got infected with COVID-19; illustrating their different ways of presentation, management and highlighting the outcomes. Conclusion: Although SCD patients are considered as a high-risk group, all of the observed patients, and whose cases are reported here, have recovered. A large scale of SCD cases should be studied to reach more conclusive results.

Wilms' tumour (nephroblastoma) is the most common abdominal malignancy in children. Extrarenal Wilms' tumour (ERWT) is rare, with limited reports in the literature. Hereby, we report a case of unilateral ovarian Wilms' tumour, which was diagnosed initially by closed biopsy and confirmed later by histopathology study of the excised tumour. We are discussing the unusual location and presentation of Wilms' tumour and showing the medical challenges in both the initial clinical impression and the pathological diagnosis. Demonstrating therapeutic plans and showing the good outcome achieved by using the classic renal Wilms’ tumour therapy protocols.
