Myxomas of the conjunctiva

Area of Science:

• Ophthalmology
• Pathology
• Oncology

Background:

• Conjunctival myxomas are rare tumors.
• They can be misdiagnosed clinically, often as cysts.
• Understanding their clinicopathological features is crucial for accurate diagnosis and management.

Purpose of the Study:

• To investigate the clinicopathological characteristics of conjunctival myxomas.
• To differentiate these tumors from other conjunctival lesions.
• To establish diagnostic criteria and confirm benignancy.

Main Methods:

• Clinicopathological study of fourteen conjunctival myxoma cases.
• Histological and ultrastructural examination of tumor tissues.
• Analysis of patient demographics, clinical presentation, and treatment outcomes.

Main Results:

• Fourteen cases (8 males, 6 females, median age 50) presented as slow-growing, movable temporal bulbar conjunctival lesions.
• Histology revealed hypocellularity with stellate/spindle cells, mucoid stroma, and scattered mast cells.
• Ultrastructural findings identified dilated endoplasmic reticulum cisternae and nuclear membrane invaginations.

Conclusions:

• Conjunctival myxomas are benign tumors with characteristic clinicopathological features.
• Simple local excision is an effective treatment with no recurrence.
• Distinguishing conjunctival myxomas from other myxomatous tumors is essential.
