Abstract:
Non Hodking´s lymphoma (NHL) may involve bones but synovial involvement is uncommon. We describe a patient who presented with polyarthritis, sicca symptoms and rash suggestive of rheumatoid arthritis. An atypical skin rash prompted skin and synovial biopsies. A diagnosis of synovial and skin malignant large B-cell lymphoma anaplastic subtype was performed. Chemotherapy with dexamethasone, vincristine and rituximab was started. Following treatment the patient had complete resolution of cutaneous and articular lymphoma manifestations.
