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

Abstract

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. 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. 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.
