Iris melanoma in 12-year-old boy.
Clinical & Experimental Ophthalmology
|July 29, 2006
Summary
A rare iris melanoma was diagnosed in a 12-year-old boy following blunt ocular trauma. This case highlights the importance of investigating iris lesions, even in young patients, for potential malignant melanoma.
Area of Science:
- Ophthalmology
- Oncology
- Pathology
Background:
- Iris melanomas are rare ocular tumors.
- Prepubertal presentation of iris melanoma is exceptionally uncommon.
Observation:
- A 12-year-old boy presented with an incidental iris lesion after blunt eye injury.
- Ocular examination revealed a large, atypical, vascular nodule in the nasal iris with smaller nodules in the iris and anterior chamber.
- Ultrasound biomicroscopy excluded posterior tumors; fundal examination was normal.
Findings:
- Sector iridectomy confirmed a mixed spindle and epithelioid melanoma.
- Histopathology revealed malignant melanoma confined to the iridocorneal angle, iris, ciliary body, and anterior sclera.
Implications:
- This case underscores the possibility of iris melanoma in pediatric patients, necessitating thorough diagnostic evaluation.
- Early detection and diagnosis are crucial for managing rare ocular malignancies in children.
