    Summary

    This study reports the first case of intraocular hemangiopericytoma, a rare vascular tumor. The diagnosis was confirmed via electron microscopy in a patient with a choroidal lesion.

    Area of Science:

    • Ophthalmology
    • Surgical Pathology
    • Oncology

    Background:

    • Choroidal hemangiomas are vascular tumors that can cause vision impairment.
    • Hemangiopericytomas are rare tumors typically found in soft tissues, with occasional orbital involvement.

    Observation:

    • A 40-year-old woman presented with an intraocular lesion initially diagnosed as choroidal hemangioma.
    • Treatment with xenon arc photocoagulation reduced subretinal fluid, and the lesion was stable for eight years.
    • Histopathological examination revealed spindle-shaped and ovoid cells with capillaries, surrounded by reticulin fibers.

    Findings:

    • Electron microscopy confirmed the diagnosis as hemangiopericytoma, characterized by proliferating pericytes and basal lamina.
    • This represents the first documented case of an intraocular hemangiopericytoma.

    Implications:

    • The choroid's vascular nature makes it a plausible origin for hemangiopericytomas.
    • Hemangiopericytoma should be considered in the differential diagnosis of vascular choroidal lesions.
