Methotrexate-associated lymphoproliferative disorders in the central nervous system and stomach: A case report
RATIONALE: Methotrexate-associated lymphoproliferative disorder (MTX-LPD) is a serious complication in patients treated using methotrexate. It occasionally develops in extra-nodal sites, but rarely in the central nervous system (CNS) or in 2 different sites at the same time. We present the rare case...

Sumario: | RATIONALE: Methotrexate-associated lymphoproliferative disorder (MTX-LPD) is a serious complication in patients treated using methotrexate. It occasionally develops in extra-nodal sites, but rarely in the central nervous system (CNS) or in 2 different sites at the same time. We present the rare case of a patient with rheumatoid arthritis who developed lymphoma in the CNS and stomach during MTX therapy. PATIENT CONCERNS: A 75-year-old Japanese man with rheumatoid arthritis who received methotrexate was admitted to our hospital because of gait ataxia and anorexia. DIAGNOSES: Imaging findings and biopsy led to a diagnosis of 2 different types of MTX-LPD in the central nervous system and stomach. INTERVENTIONS: The lesion in his stomach improved after methotrexate withdrawal, whereas the cerebellar mass required high-dose methotrexate and rituximab therapy. OUTCOMES: Complete remission has been maintained for the 2 years following the initiation of chemotherapy. LESSONS: In patients with RA who receive MTX and develop new neurological symptoms, CNS lymphoma as an MTX-LPD may be considered as a differential diagnosis. |
