Iris melanocytoma in child diagnosed by fine needle aspiration biopsy

Area of Science:

• Ophthalmology
• Cytopathology
• Pediatric Oncology

Background:

• Iris melanocytoma is a rare benign tumor.
• Accurate diagnosis is crucial for appropriate management.
• Minimally invasive diagnostic techniques are preferred in pediatric cases.

Purpose of the Study:

• To report a case of large iris melanocytoma diagnosed via fine needle aspiration biopsy (FNAB) in a child.
• To highlight the utility and accuracy of FNAB in diagnosing iris tumors.
• To compare FNAB with other biopsy methods for iris lesions.

Main Methods:

• A case report of a child with a large iris melanocytoma.
• Diagnosis was established using fine needle aspiration biopsy (FNAB).
• Cytologic features were analyzed for diagnostic confirmation.

Main Results:

• FNAB yielded cytologic features characteristic of melanocytoma.
• The technique demonstrated high accuracy (>99%) for tumors >3 mm.
• FNAB presented a lower risk of local spread than incisional biopsy.

Conclusions:

• FNAB is a valuable and accurate tool for diagnosing large iris melanocytoma in children.
• FNAB offers an advantage over incisional biopsy due to its minimal risk of local spread.
• Potential complications include intralesional hemorrhage and hyphema.
