Dural-Based Marginal Zone Lymphoma in a Patient with Sarcoidosis.

BACKGROUND: Primary dural-based lymphoma is a rare disease entity. It has been hypothesized that patients with sarcoidosis are at increased risk of developing lymphoma, an association known as "sarcoidosis-lymphoma syndrome," although dural disease has not yet been reported in the literature. CASE DESCRIPTION: Here we report the first case of dural-based lymphoma in a 60-year-old man with a history of sarcoidosis, in keeping with sarcoidosis-lymphoma syndrome. His dural-based tumor was surgically resected. Pathology examination revealed a marginal zone B-cell lymphoma. Subsequent neural and systemic staging confirmed a localized lymphoma. The patient received local radiotherapy to control leptomeningeal disease. CONCLUSIONS: Given the association between sarcoidosis and lymphoma, we suggest lymphoma to be considered as one of the top differentials for a dural-based mass lesion in patients with sarcoidosis.
