This case report describes concurrent splenic peliosis and vascular Ehlers-Danlos syndrome (EDS) in a 59-year-old male patient. After splenic rupture due to peliosis, the complicated postoperative period hinted at the possibility of vascular EDS. This diagnosis was confirmed by genetic testing, which revealed a novel point mutation in the COL3A1 gene, c.2545G-->C, leading to a codon encoding for arginine instead of glycine (p.Gly849Arg). In addition, a histological diagnosis of splenic peliosis could be established.

We report the case of a 75-year-old woman who presented with fever, right back pain, paresthesia in the right extremities, erythema, purpura, and nodules. She had previously initiated dialysis due to rapidly progressive glomerulonephritis and was transferred to our hospital. Imaging studies revealed multiple cerebral and splenic infarcts and hemorrhage encapsulating the right kidney, likely due to microaneurysms in multiple renal arteries.

Microscopic polyangiitis (MPA) affects small and medium vessel, which sometimes leads to arterial aneurysms. In English database, only 15 reports refer to ruptured aneurysms in MPA. We experienced a fatal case with MPA who developed multiple visceral aneurysms, resulting in rupture of the hepatic aneurysm.

Immunologic thrombocytopenic purpura (ITP) is a condition that affects four to 18 per 100 000 children every year. In most cases, spontaneous remission occurs, but splenectomy may be proposed. Exploring the site of platelet sequestration can help to better predict potential poor responders to splenectomy, but In-radiolabeled platelet scintigraphy (IPS) can be difficult to perform in children with very few platelets.

Waterhouse-Friderichsen Syndrome (WFS) is a rare but life-threatening condition characterized by massive adrenal hemorrhage. WFS represents one of the features of the Overwhelming Post-Splenectomy Infection, which occurs any time after spleen removal and is recognized as the most serious complication in asplenic patients. We report a fatal case of WFS resulting from Streptococcus pneumoniae infection in a vaccinated and splenectomized patient.

Immune thrombocytopenia (ITP) is a common hematological disorder. Our previous study has found that exosomal miR-146a-5p derived from bone marrow mesenchymal stromal cells (BMSCs) regulate Th17/Treg balance to alleviate ITP. This work further investigated the role of miR-146a-5p in ITP with pregnancy.
