Summary

Malignant non-Hodgkin lymphoma is the most frequent primary malignant orbital tumor. Accurate diagnosis of orbital lymphoid infiltrations requires careful histological examination and immunohistochemistry for appropriate patient management.

Area of Science:

  • Ophthalmology
  • Oncology
  • Pathology

Background:

  • Orbital tumors represent a diverse group of neoplasms requiring accurate diagnosis for effective management.
  • Lymphoid infiltrations are a significant component of orbital lesions, necessitating differentiation between benign and malignant entities.

Observation:

  • This series of 100 orbitotomies for tumor revealed lymphoid infiltrations in 27% of cases.
  • Malignant non-Hodgkin lymphoma was identified as the most common primary malignant orbital tumor.
  • The study also details the first reported case of primary orbital Castleman's disease and analyzes 27 cases of pure orbital lymphoid infiltrations.

Findings:

  • The natural history of conjunctival lymphomas differs from orbital lymphomas, leading to their exclusion from this series.

  • Histological examination with fresh, unfixed tissue for immunohistochemical staining is crucial for diagnostic accuracy.
  • Multiple biopsies may be necessary to establish a definitive diagnosis.

    • Implications:

    • Accurate histological and immunohistochemical analysis is vital for differentiating various orbital lymphoid disorders.
    • Distinguishing between different types of orbital lymphoid lesions impacts treatment strategies and patient outcomes.
    • This study underscores the importance of comprehensive histopathological evaluation in managing orbital tumors.
