Burkitt lymphoma is an aggressive B-cell non-Hodgkin lymphoma (NHL). Primary CNS lymphoma (PCNSL) is a rare disease, and the subtype of Burkitt lymphoma presenting as a sole CNS lesion is an even rarer diagnosis. Acute sudden blindness is a rare presenting symptom of PCNSL or NHL in general. We present an interesting case of a four-year-old boy with dysmorphic features whose visual examination showed a sudden bilateral loss of vision. There was bilateral eye proptosis and complete ptosis. Extraocular muscles were fixed straight. The pupils were fixed and mid dilated bilaterally and there was grade 3/4 papilledema in both eyes. Neuroimaging showed a mass in the base of the skull, extending to orbits and sinuses. A cervical biopsy of the enlarged lymph nodes was taken and a histopathological diagnosis of Burkitt lymphoma was made. Genetic analysis showed a GNB1 mutation, and the patient was diagnosed with Kabuki syndrome by a pediatrician, based on characteristic dysmorphic features. Treatment with steroids and chemotherapy was initiated., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Periorbital atopic dermatitis (AD) is a common sign in ophthalmological practice and usually has a persistent and relapsing course. Treatment with topical corticosteroids has various side effects associated with their usage. Tacrolimus topical ointment has unique immunomodulatory properties that decrease skin inflammation and pruritus in AD. In this case series, we present a prospective case series of five patients (three males and two females) who received topical application of tacrolimus ointment 0.1-0.03% in the periorbital area twice daily for one to four weeks. The pre- and post-treatment images of all patients were recorded to compare the effects of the treatment. The cases were selected from patients attending the outpatient clinics of East Jeddah Hospital, Saudi Arabia. All patients were suffering from AD. Patients underwent a clinical assessment by tactile inspection (location, size, color, and surface condition) in the first week, secondweek, third month, and first year. We may conclude from this study that tacrolimus showed promising outcomes and is safe and effective for the treatment of flares or resistant periorbital AD in both adults and children., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Alzahrani et al.)
