Review Case Reports
Non-traumatic False Cyst of the Spleen: A Case Report and Review of the Literature.
False cysts have no cellular lining and usually originate from past abdominal trauma. We herein report a 23-year-old woman with an asymptomatic splenic false cyst. She had no history of abdominal trauma. ⋯ Although the images were not typical of a splenic false cyst, the surgically excised mass histologically showed a splenic false cyst (no epithelial element). Non-traumatic splenic false cysts are rare and show nonspecific clinical findings and symptoms. The recommended treatment is splenectomy.

Case Reports
Hemodialysis Patient with Streptococcal Toxic Shock Syndrome and Penile Necrosis: A Case Report.
A 72-year-old man on hemodialysis due to diabetic nephropathy presented with a fever and penile pain. Although his physical examination was unremarkable, his general condition deteriorated. ⋯ Autopsy suggested penile necrosis due to septic shock. STSS in hemodialysis patients with vascular calcification, even in the absence of calciphylaxis, can lead to severe organ damage due to ischemia.

A 43-year-old Japanese woman with rheumatoid arthritis treated by infliximab and methotrexate for 11 years was admitted for proteinuria and purpura. A kidney biopsy revealed endothelial damage-dominant nephritis with IgA deposition. ⋯ After 6 months, urinary protein was less than 0.1 g/day, and purpura subsided. To our knowledge, this is the first case of endothelial damage-dominant nephritis related to IgA vasculitis involving the skin and kidney after long-term use of infliximab and methotrexate.

A 32-year-old man was admitted for the evaluation of proteinuria (5.69 g/day). A light microscopic examination showed markedly dilated glomerular capillary loops with vacuolated areas in many glomeruli, and vacuolated areas were seen on peritubular capillaries in the tubulointerstitium. ⋯ A genetic analysis of apoE showed that the lipoprotein glomerulopathy was due to apoE-Sendai (Arg145Pro, p. R163P) heterozygosity, which was found in not only the patient but also his mother and twin brother.

A 26-year-old Japanese woman was admitted with a 1-month history of diarrhea, a high fever for a few days, and exacerbation of dyspnea. She was treated with an antifibrotic drug and long-term oxygen therapy for Hermansky-Pudlak syndrome-related pulmonary fibrosis. ⋯ Steroid pulse therapy and intravenous cyclophosphamide improved chest CT findings and diarrhea. Therefore, immunosuppressant treatment should be considered for systemic inflammation related to MPO-ANCA.
