Concurrent occurrence of hemangioendothelioma in the spleen and liver of a 1-year-old child is a rare clinical case.She had a history of good health. Laboratory tests showed elevated inflammatory markers, but all other parameters were within normal range. In this article, we exhibit the typical clinical presentation and Pathology imaging features of this disease.CT imaging revealed a 9.8 cm×8.6 cm mass in the spleen, with areas of non-enhancing liquefactive necrosis. The mass exhibited heterogeneous enhancement during the arterial phase and progressive enhancement during the venous phase. Multiple nodules were observed in liver segments S2 and S4, the largest being approximately 3.7 cm×3.5 mm, with enhancement patterns similar to the splenic lesion. The patient underwent splenectomy, left hemihepatectomy, and cholecystectomy. Intraoperatively, the splenic mass exhibited some areas appearing spongy. Multiple nodules were observed in the left liver, presenting as gray-brown solid masses with a spongy texture. Pathology confirmed a diagnosis of hemangioendothelioma, supported by positive immunohistochemical staining for CD31, CD34, ERG, and FLI-1.

Splenic hemangioma is the most common pathological classification of splenic tumors, and its surgical indication and treatment have been controversial. Before, open splenectomy was usually used to treat splenic hemangioma. Following the rapid development of laparoscopic techniques, people's requirements for minimally invasive treatment have gradually increased, and laparoscopic splenectomy has gradually become the main treatment method.

Introduction: Littoral cell angioma (LCA) is a new subtype of vascular tumor, which has been reported infrequently worldwide. It is associated with visceral malignancies and other immunologic conditions.
Clinical Case: We present a case of a 70-year-old Caucasian male with a 6-year history of myelodysplastic syndrome, which was investigated for splenomegaly and pancytopenia.

Article Synopsis
- Splenic hemangioma is a rare benign tumor that can cause life-threatening issues if it ruptures; safe management is crucial due to the spleen's importance in immunity and blood filtration.
- A 51-year-old patient with a large spleen hemangioma was treated successfully with embolization, preserving the spleen and avoiding complications.
- The case report highlights the procedure's safety, symptom relief without surgery, and lower complication rates compared to traditional surgical methods, with a notable 2-year follow-up showing significant size reduction of the hemangioma.

Background: Robotic-assisted partial splenectomy (RAPS) is a superior approach for treating splenic cysts and splenic hemangiomas, as it preserves the immune function of the spleen and reduces the risk of overwhelming post splenectomy infection. Currently, there are no standardized guidelines for performing a partial splenectomy.
Case Summary: Four patients with splenic cysts or splenic hemangiomas were treated by RAPS.
Epidermoid cyst in intrapancreatic accessory spleen (ECIPAS) is a rare benign condition that occasionally mimic malignant pancreatic neoplasms. We present a case of ECIPAS in a 53-year-old asymptomatic male, initially discovered incidentally during imaging for a suspected hepatic hemangioma. The lesion, located in the pancreatic tail, demonstrated characteristic imaging features on contrast-enhanced computed tomography and superparamagnetic iron oxide (SPIO)-enhanced magnetic resonance imaging (MRI), including a cystic component with peripheral solid tissue exhibiting splenic enhancement patterns.
