Summary
Retinoblastoma, a rare eye cancer, can occur in eyes with microphthalmia, even without a family history. Early detection is crucial, as this case highlights the need to consider retinoblastoma in small eyes.
Area of Science:
- Ophthalmology
- Pediatric Oncology
- Medical Genetics
Background:
- Retinoblastoma is the most common primary intraocular malignancy in children.
- Microphthalmia is a congenital condition where one or both eyes are abnormally small.
- Genetic factors and family history play a role in retinoblastoma development.
Observation:
- A 4-year-old girl presented with a large intraocular mass within a microphthalmic eye.
- The patient had no reported family history of retinoblastoma.
- The intraocular tumor exhibited rapid growth, necessitating enucleation.
Findings:
- Microscopic examination confirmed the presence of retinoblastoma.
- Histological analysis revealed Flexner-Wintersteiner rosettes, a characteristic feature of retinoblastoma.
- This case represents a rare occurrence of retinoblastoma in unilateral microphthalmia.
Implications:
- Retinoblastoma diagnosis should not be dismissed solely based on the presence of microphthalmia.
- The possibility of retinoblastoma must be considered in pediatric patients with microphthalmia, especially with unknown or incomplete family histories.
- This case underscores the importance of thorough ocular examination and diagnostic consideration in atypical presentations of pediatric eye cancers.
