Extranodal marginal zone lymphoma of the dura: a case report.

Extranodal marginal zone lymphoma of the dura: a case report.

Dec 2012

Department of Neurosurgery, Kagoshima City Hospital.


The authors present the case of a 65-year-old woman who initially was diagnosed as having intracranial dural B-cell malignantlymphoma. She survived more than 9 years after surgery and radiation. We re-examined the specimens pathologically. Histological findings confirmed an extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT) that showed numerous IgG4-positive plasma cells. MALT lymphomas are already recognized as a distinct clinico-pathological entity. A primary dural MALT lymphoma is very rare and has a favorable clinical outcome, and patients are expected to have an excellent long-term survival with local therapy alone.
