Background:
Primary orbital lymphomas are a rare subset of tumors constituting 1-2% of non-Hodgkin's lymphoma. They are mostly indolent B-cell lymphomas presenting with gradual progressive proptosis, decreased visual acuity, restricted ocular mobility, and diplopia. The role of surgery is mainly for obtaining a biopsy. Most of these tumors require multimodality treatment including chemotherapy, radiation, or both, which have major role.
Case description:
We report one such case of marginal zone lymphoma of the orbit in a female with significant proptosis who was treated with multimodality treatment, including surgical excision as a major treatment modality. Decompression of symptomatic proptosis was followed by chemotherapy and radiation.
Conclusion:
Primary orbital lymphoma is a rare clinical entity with diverse clinical outcomes. It can be successfully managed with surgical excision for decompression of mechanical proptosis followed by chemotherapy, radiation, or both.
