A 71-year-old woman being treated with methotrexate (MTX) and tacrolimus (TAC) for rheumatoid arthritis (RA) was admitted to our hospital and underwent surgery for gastric perforation and peritonitis. An endoscopic examination six days post-surgery showed an extensive ulcer in the stomach, and a biopsy revealed diffused large B-cell lymphoma. We diagnosed her with immunodeficiency-associated lymphoproliferative disorder (LPD) and discontinued the MTX and TAC. She underwent gastrectomy due to stenosis approximately two months after the first operation, but the histopathological findings of lymphoma had disappeared. LPD should be considered as a potential cause of gastric perforation during RA treatment.
We herein report a woman in her 50s with systemic lupus erythematosus (SLE) who developed swelling and pain in her fingers; the symptoms were more prominent in winter. Magnetic resonance imaging (MRI) revealed bone edema in the phalanges of both hands, which was compatible with phalangeal microgeodic syndrome (PMS). This is the first reported case of PMS in a patient with SLE and suggests that performing MRI should be considered for patients with SLE in order to assess the nature of finger symptoms and signs more precisely.
