Update of ocular reticulum cell sarcoma

H A Sloas, J Starling, D G Harper

    Archives of Ophthalmology (Chicago, Ill. : 1960)
    |June 1, 1981
    PubMed
    Summary

    Reticulum cell sarcoma affecting the brainstem and vitreous was diagnosed via vitreous cytology, not initial imaging. This rare cancer responded well to steroids and radiation therapy, achieving a one-year remission.

    Area of Science:

    • Ophthalmology
    • Neurology
    • Oncology

    Background:

    • Reticulum cell sarcoma (RCS) is a rare malignancy that can affect various organs.
    • Ocular and central nervous system (CNS) involvement, particularly the brainstem, presents diagnostic challenges.

    Observation:

    • A 45-year-old man presented with diplopia due to a rare partial third cranial nerve palsy, followed by uveitis.
    • Initial diagnosis favored brainstem glioma based on CT scans and clinical presentation.

    Findings:

    • Vitreous aspirate cytology definitively diagnosed reticulum cell sarcoma, correcting the initial misdiagnosis.
    • The patient experienced an excellent visual response to oral steroids, which is uncommon in reported cases.
    • Definitive treatment with cobalt (gamma) radiation therapy resulted in a one-year remission.

    Implications:

    • Vitreous cytology is crucial for diagnosing rare ocular and CNS malignancies like RCS.
    • Early diagnosis and multimodal treatment (steroids and radiation) can lead to favorable outcomes.
    • This case highlights the importance of considering rare diagnoses in atypical presentations.
