    Area of Science:

    • Ophthalmology
    • Oncology
    • Developmental Biology

    Background:

    • Retinoblastoma is a pediatric eye cancer originating from the neuroectodermal tissue of the retina.
    • Understanding its cellular morphology and growth patterns is crucial for diagnosis and treatment.
    • This case study investigates a unilateral Retinoblastoma in a young child without a family history.

    Observation:

    • A detailed clinical and morphological analysis was performed on a single case of unilateral Retinoblastoma.
    • Scanning electron microscopy was utilized to examine cellular surface organization and tumor infiltration.
    • Specific attention was given to the structure and tridimensional characteristics of rosettes within the tumor.

    Findings:

    • The study characterized the cellular morphology and histological organization, highlighting the presence and nature of rosettes.

    Related Experiment Videos
