    Summary
    This summary is machine-generated.

    A rare conjunctival elastofibroma oculi was identified in a 69-year-old woman. This benign tumor, characterized by collagen and elastic fibers, is distinct from common lesions like pterygia.

    Area of Science:

    • Ophthalmology
    • Pathology
    • Dermatology

    Background:

    • Conjunctival lesions can present with diverse histological features.
    • Distinguishing between benign and malignant growths is crucial for patient management.

    Observation:

    • A placoid lesion with a pterygoid head was observed, extending from the temporal limbus.
    • Histopathology revealed thickened collagen bundles, adipose tissue, and mature elastic fibers.
    • Electron microscopy confirmed mature elastic fibers within thickened collagen.

    Findings:

    • The lesion was identified as an elastofibroma oculi, a rare conjunctival tumor.
    • It differs from pterygium and pinguecula by sparing the subepithelial conjunctiva and lacking dystrophic elastic fibers.
    • The findings suggest activated fibroblasts contributed to the collagen and elastic fiber proliferation.

    Implications:

    • This case expands the understanding of rare conjunctival tumors.
    • Histological and ultrastructural analysis is key to differentiating elastofibroma oculi from other conditions.
    • Further research may elucidate the specific triggers for fibroblast activation in this condition.
