Case Reports
Malignant Peritoneal Mesothelioma Presenting with Polymyalgia Rheumatica-like Syndrome.
A 30-year-old man was admitted to our hospital because of pain in his proximal extremities. The pain mimicked polymyalgia rheumatica (PMR) and it temporarily improved by a low dose of glucocorticoids, but his symptoms relapsed many times. ⋯ Finally, we diagnosed this PMR-like syndrome to be paraneoplastic syndrome with MPM. Although cases of MPM complicated by PMR-like syndrome are rare, MPM should be taken into account in the differential diagnosis.

Objective We investigated the continuation rate, safety and efficacy of treatment with hydroxychloroquine (HCQ) in a retrospective cohort of systemic lupus erythematosus (SLE) in a Japanese municipal hospital. Methods All of the patients with SLE who started treatment with HCQ were included in this study. A retrospective chart review was performed. ⋯ Conclusion The continuation rate of HCQ treatment was high in an SLE cohort of a Japanese municipal hospital. Although more than half of the patients experienced AEs, the readministration of HCQ was often successful. HCQ treatment provided benefits regarding the clinical and immunological findings in Japanese patients with SLE, which would likely lead to glucocorticoid tapering.

Spontaneous intracranial hypotension (SIH) is an important cause of headache mainly associated with spinal cerebrospinal fluid leakage. We herein report the case of a 51-year-old man who developed SIH after swimming. ⋯ The splenial lesion disappeared and SDH improved after an epidural blood patch. This case emphasizes that transient SCC lesions could coexist with SIH and that SIH should be considered in the differential diagnosis of SCC lesions.

Case Reports
A Case of IgG4-related Disease Manifesting as Gastroduodenal Ulcer Diagnosed by an Endoscopic Biopsy.
A 26-year-old man was admitted to our hospital due to upper abdominal pain. He had previously been diagnosed with gastroduodenal ulcer at 23 and 25 years old and had been treated with proton-pump inhibitors. ⋯ Based on the clinicopathologic findings and after excluding other causes, he was diagnosed with IgG4-related gastroduodenal ulcer. We herein report a rare case of IgG4-related disease manifesting as a gastroduodenal ulcer diagnosed by an endoscopic biopsy.

We encountered a patient with multiple myeloma treated with autologous hematopoietic stem cell transplantation (HSCT) who developed repeated episodes of enteritis but regressed spontaneously. An endoscopic examination revealed no abnormalities, but biopsy specimens showed massive infiltration of CD4+ and Epstein-Barr encoding region (EBER+) abnormal lymphocytes in which a high copy number of Epstein Barr virus (EBV) genomes was detected by quantitative polymerase chain reaction (qPCR). EBV infection was exclusively detected in CD4+ T-cells, leading to a diagnosis of EBV-positive CD4+ T-cell lymphoproliferative disorder (LPD). This case suggests that an immediate biopsy and examinations, including qPCR for EBV DNA, should be considered for patients with recurrent enteritis after autologous HSCT, regardless of endoscopic findings.
