Littoral cell angioma is a benign vascular tumour of the spleen, and malign transformation is seldom. The angioma is associated with a high risk of simultaneous occurrence of other primary cancers, and it is of utmost importance to perform extensive diagnostic investigations to detect other cancers. Definitive treatment of littoral cell angioma is surgical resection of the spleen. This is a unique case report about a 73-year-old woman who had a simultaneous adenocarcinoma of the colon and a gastrointestinal stromal tumour. She underwent simultaneous splenectomy with colonic and gastric resection.

According to the UEMS (Union Europeene des Medicins Specialises) Section of surgery Board of Surgery, "Emergency Surgery" can be defined "as surgery that is required to deal with an acute threat to life, organ, limb or tissue caused by external trauma, acute disease process, acute exacerbation of a chronic disease process, or complication of a surgical or other interventional procedure". Performance of emergency surgery require complex and varied skills and abilities to achieve procedures from different fields of surgery: abdominal, urologic, thoracic, vascular, soft tissue, skeletal) within an interval of 24 hours (1). In U.S., since 2008, Acute Care Surgery concept was introduced, and nowadays is an evolving specialty with three essential components- trauma, critical care and emergency surgery (2). In UK there is an increasing subspecialisation within general surgery over the last ten years. More recently, there has been an increase in focus on emergency general surgery (3,4). This may not come as a surprise given the fact that trafic crashes kill 1.2 million people annually around the world (3242 people/day) and 90% are in middle and low income countries. In US trauma is the leading cause of death in persons up to 40 years. Optimal care for emergency surgical patients is one of the major challenges for every healthcare system worldwide. An emergency surgery mai intervene during the daily schedule of elective interventions and create pressure on both the organisation and costs (5). Since it's birth, in 2007, the Romanian Society for Emergency Surgery and Trauma was involved in supporting the development of practice in emergency surgery in Romania by many actions: each year, during biannual National Congres and National Conference of the Romanian Society of Surgery 2 sessions were dedicated to emergency surgery, with invited foreign speakers; oragnisation of European Congres of Emergency and Trauma Surgery in 2017 in Bucharest, 1 tematic issue of Chirurgia Journal dedicated to surgery of the cirrhotic patients. This tematic isssue includes varia subjects from emergency surgery in valuable articles. The management of open abdomen management are depicted by Anastasiu et al, in a review summarizing definition, classification, indications, methods of temporary abdominal closure and fascial closure, and enterocutanous fistula. Turculet et al, perfomed a review of the litterature to describe the main advantages and disadvantages of the trauma systems in Europe and to present the last concepts regarding the management of the polytrauma patients and the newest sets of measures to prevent car crashes in European Union. A rare case of small bowel hemangioma with hemoperitoneum mimicking trauma is described by Iordache et al, with a review of the litterature. The series of reviews ends with an interesting article for daily practice in emergency hospitals about the diagnostic and therapeutic peculiarities in abdominal trauma associated with spinal cord injurie by Grigorean et al. Abdominal trauma is addressed in 7 original papers. The definitive surgery for liver trauma in tertiary HPB center, the nonoperative treatment of abdominal trauma involving liver and spleen, the timing of splenic interventional radiology, the management of colon trauma at a level II trauma, challenges raised by the retroperitoneal hematoma in abdominal trauma, predicition of evolution of patients with abdominal trauma using the usual biological parameters, and clinico-pathological correlations in the acute surgical abdomen in the pre and post COVID-19 pandemic period are presented, analysed and discussed in papers coming from specialized surgical units from Fundeni Clinical Institute, Emergency Clinical Hospital Bucharest, Emergency University Hospital of Bucharest, "Bagdasar-Arseni" Clinical Emergency Hospital, "St. Pantelimon" Clinical Emergency Hospital, Clinical County Emergency Hospitals of Craiova and Tg-Mures. The surgical technique of intraomental splenic implant and an attempt of reassessement is presented in a paper by Beuran et al. We hope that this tematic issue will be an interesting and very useful lecture for our readers and bring useful informations for those involved in emergency surgery.

Review
CONTEXT.—
Even though immunohistochemistry is routinely used by pathologists, evaluation of immunohistochemistry in splenic lesions remains difficult for many. Classification of benign and splenic lesions often requires a combination of hematoxylin-eosin evaluation, immunophenotyping, and sometimes molecular testing. Immunohistochemical staining is essential in evaluating many splenic lesions, and requires an understanding of the normal compartments of the spleen.
OBJECTIVE.—
To address different immunohistochemical features used for identification and subclassification of different lesions of the spleen, as well as in the normal compartments of the spleen.
DATA SOURCES.—
The information outlined in this review article is based on our experiences with a variety of spleen cases, on the current World Health Organization classification of hematopoietic and lymphoid tumors, and on a review of English-language articles published during 2018.
CONCLUSIONS.—
Features for phenotyping normal spleen as well as a variety of splenic lesions, including littoral cell angioma and splenic marginal zone lymphoma, are discussed. Suggested immunopanels are provided to assist in the diagnosis of different lesions of the spleen.

BACKGROUND
Spontaneous splenic rupture (SSR) is a rare, often life-threatening, acute abdominal injury that requires immediate diagnosis and early treatment. SSR is mainly treated surgically or conservatively. A few cases of interventional embolization for SSRs have been reported.
CASE PRESENTATION
A 30-year-old male patient complaining mainly of left upper abdominal pain underwent emergency abdominal computed tomography (CT) and showed enlargement of the spleen with a massive mixed-density shadow approximately 10.0 × 8.0 × 12.5 cm in size. The boundary was unclear and showed obvious progressive enhancement. Considering the intrasplenic tumor lesions with rupture and hemorrhage, the possibility of vascular tumors was high, with intraperitoneal blood and fluid accumulation. Digital subtraction angiography of the splenic arteriography and embolization of the ruptured splenic artery branches were performed. Postoperative hemoglobin progressively decreased, inflammatory indicators, such as white blood cell counts, procalcitonin (PCT), and C-reactive protein (CRP) were significantly increased, and 2 days after embolization, the patient developed severe hypoxemia, shock, pulmonary edema, and acute respiratory distress syndrome. CT re-examination 9 days after embolization showed reduced lesion absorption. After stabilization of the condition, splenectomy was performed, and postoperative platelet count increase, anticoagulant improvement, and discharge were observed. Postoperative pathological examination revealed extensive hemorrhage and necrosis, vascular tissue with abnormal hyperplasia in the surrounding area, vascular tissue in the bleeding area and outer wall (elastic fiber staining +), and local myofibroblast hyperplasia. Immunohistochemistry showed actin (SM +) and Ki67 (10% +).
CONCLUSION
SSR caused by splenic hemangioma is rare, and the choice between surgical treatment or splenic artery embolization remains dependent on the patient's hemodynamic stability and imaging findings.

The present study aimed to explore the clinical efficacy of laparoscopic partial splenectomy in the treatment of benign lesions of the spleen and partial splenic rupture. The clinical value of laparoscopic partial splenectomies performed between March 2015 and May 2022 was retrospectively analyzed. Cases considered included the following: 14 spleen cysts, five spleen hemangiomas, one spleen hamartoma and two splenic ruptures. Lesion diameters of cases ranged from 5.0-11.3 cm. Results indicated that all 22 patients had an uneventful surgery, including 11 cases with lesions located in the upper pole of the spleen, nine in the lower pole of the spleen, one in the upper middle pole and one in the middle and lower pole. Operation time ranged from 75-180 min (mean: 120±17 min) and intraoperative bleeding ranged from 80-300 ml (mean: 178±70 ml). The average duration of postoperative hospitalization was 6±2 days, with all patients followed up for 10-12 months. Patients reported no symptoms of discomfort and had platelet levels within normal range. In conclusion, laparoscopic partial splenectomy allows for lesion resection while retaining normal splenic function and may be effectively used for treating benign spleen tumors and partial splenic rupture. However, the operation is difficult and surgeons must be able to perform minimally invasive techniques and strictly screen cases.

Review
Cross-sectional imaging of the upper abdomen, especially if intravenous contrast has been administered, will most likely reveal any acute or chronic disease harbored in the spleen. Unless imaging is performed with the specific purpose of evaluating the spleen or characterizing a known splenic lesion, incidentally discovered splenic lesions pose a small challenge. Solitary benign splenic lesions include cysts, hemangiomas, sclerosing angiomatous nodular transformation (SANT), hamartomas, and abscesses, among others. Sarcoidosis and tuberculosis, although predominantly diffuse micronodular disease processes, may also present as a solitary splenic mass lesion. In addition, infarction and rupture, both traumatic and spontaneous, may take place in the spleen. This review aims to describe the imaging features of the most common benign focal splenic lesions, with emphasis on the imaging findings as these are encountered on routine cross-sectional imaging from a multicenter pool of cases that, coupled with clinical information, can allow a definite diagnosis.

BACKGROUND
Hepatic epithelioid hemangioendothelioma (HEHE) is a rare hepatic vascular tumor with unpredictable malignant potential. The etiology, characteristics, diagnosis, treatment, and prognosis of HEHE are not well-understood, and large-scale retrospective studies are required to understand better this disease.
AIM
To determine the characteristics of HEHE and identify its optimal treatments and prognostic factors.
METHODS
The clinical data of two patients diagnosed with HEHE at the Fourth Hospital of Hebei Medical University and 258 previously reported cases retrieved from the China National Knowledge Infrastructure and PubMed databases between 1996 and 2021 were combined and summarized. All cases were pathologically identified as HEHE. Information such as clinical features, laboratory examination findings, imaging findings, pathological characteristics, treatment, and survival periods was reviewed. Kaplan-Meir curves were used for survival analysis. Prognostic factors were identified by Cox regression analysis.
RESULTS
HEHE primarily affected middle-aged women. The typical manifestations included epigastric pain, hepatosplenomegaly, inappetence, distension, weight loss, and fatigue. Tumor markers were expressed normally. The incidence of extrahepatic metastasis was 34.5% at the time of diagnosis. The most common sites of extrahepatic involvement were the lungs (22.3%), lymph nodes (5.6%), peritoneum (3.6%), bones (6.6%), and spleen (5.1%). Furthermore, "capsular retraction", "target sign", and "lollipop sign" were the characteristic features of HEHE on imaging. The immunohistochemical profile for HEHE (expression of vascular markers, such as factor VIII-related antigen, CD31, and CD34; expression levels of D2-40) can facilitate and ensure an accurate diagnosis. The management options for patients with HEHE include liver resection (29.7%), liver transplantation (16.1%), palliative treatments (12.7%), transhepatic arterial chemotherapy and embolization (TACE, 10.2%), chemotherapy (11.0%), antiangiogenic therapy (15.3%), and other treatments (5.1%); the mean survival time was 158.6, 147.3, 4.2, 90.8, 71.4, 83.1, and 55.0 mo, respectively. The survival time of patients who underwent surgical treatment was longer than that of patients who did not. TACE and antiangiogenic therapy tended to prolong survival compared with other nonsurgical treatments. The 1-, 5-, and 10-year survival rates were 82%, 71%, and 64%, respectively. Multivariate analysis showed that liver function ( = 0.045), intrahepatic metastasis ( = 0.029), and treatment ( = 0.045) were independent prognostic factors. The presence of extrahepatic metastases was not an independent risk factor for poor prognosis ( = 0.558).
CONCLUSION
The clinical course of HEHE is rare and variable, and patients with intrahepatic metastases and liver dysfunction may have a poorer prognosis than those without. Surgical intervention, whether liver resection or transplantation, might be warranted regardless of extrahepatic metastasis. For patients without the option for surgery, clinicians should consider the use of TACE with antiangiogenic drugs in the treatment of HEHE.

Extraskeletal osteosarcoma is a rare malignant soft-tissue sarcoma that is difficult to diagnose. Surgery is a common treatment, although chemotherapy and radiotherapy are also used. Patients at risk of bleeding can undergo embolization combined with resection. The occurrence of primary splenic extraskeletal osteosarcoma in humans does not seem to have been reported in the literature. A 50-year-old woman who complained of pain in the left upper abdomen for 1 day was initially diagnosed with "splenic hemangioma with a high possibility of rupture and bleeding" and urgently underwent digital subtraction angiography, combined with splenic arteriography and embolization. Abdominal pain worsened 2 days postoperatively, with a hemoglobin level of 106.0 g/L. Consequently, emergency laparotomy combined with splenectomy was performed. The clinical and imaging features, pathological diagnosis, and embolization treatment of this case were analyzed retrospectively. CT of the upper abdomen revealed splenomegaly, an irregular low-density shadow in the spleen, and a flake-like calcification in the lateral margin of the left kidney. Nuclear MRI of the upper abdomen showed splenomegaly and a mass (approximately 8.4 cm × 5.7 cm × 6.3 cm) below the spleen with clear boundaries-this exhibited an uneven signal, which was slightly low in T1-weighted imaging (T1WI) and slightly high in T2-weighted imaging (T2WI). Several small cystic lesions or cystic cavities were observed in the mass, which exhibited a longer T2 signal. During the enhanced scan, the signal of the lesion showed progressive enhancement, and the enhancement range increased in the delayed phase scan, as well as a hematoma below the spleen capsule and calcification below the lesion (nodular T1WI/T2WI hypointense, approximately 3.3 cm × 3.6 cm). Postoperative biopsy pathology showed splenic soft tissue tumor: at low magnification, the multinucleated giant cells were scattered; at medium magnification, osteoclast-like multinucleated giant cells were observed; and at high magnification, lace- or grid-like tumor osteogenesis was detected. Immunohistochemistry showed that the expression of CD31, CD34, F8, s-100, desmin, SMA, and CD99 was negative, whereas the expression of β-catenin, BCL-2, SATB-2, and P16 was positive. CD68 and MDM-2 showed low expression, while 50% of the cells were positive for Ki-67 expression. No abnormal concentration of radioactivity was found on the bone scan with Tc-MDP after the operation, further ruling out the occurrence of other bone tumors. The patient was diagnosed with primary extraskeletal osteosarcoma. It is necessary for multidisciplinary teams to diagnose malignant extraskeletal osteosarcomas.

A strain of avian leukosis virus (ALV) belonging to a new envelope subgroup J (ALV-J) emerged in 1988 as a new subgroup of ALV and spread rapidly throughout the world. Due to the infection and spread of ALV-J, the global poultry industry experienced a significant loss. Although the disease had been prevented and controlled effectively by culling domestic chickens in the infected zone, a few field cases of ALV-J infection were reported in China in recent years. This study was conducted to characterize the genome and analyze the lesions and histopathology of the ALV-J strain named HB2020, which was isolated from layer chickens in Hubei Province, China. The full-length proviral genome sequence analysis of ALV-J HB2020 revealed that it was a recombinant strain of ev-1 and HPRS-103 in the gene in comparison to ALV-J prototype HPRS-103. In the 3'-untranslated region (3'UTR) of the nucleotide sequence, there were found 205-base pairs (bp) deletion, of which 175 were detected in the redundant transmembrane (rTM) region. Besides, the surface glycoprotein gene had five mutations in a conservative site, whereas the transmembrane protein gene was relatively conserved. The animal experiments conducted later on this strain have shown that HB2020 can cause various neoplastic lesions in chickens, including enlarged livers with hemangiomas and spleens with white nodules. Additionally, as the exposure time increased, the number of tumor cells that resembled myelocytes in the blood smears of infected chickens gradually increased. These results indicated that HB2020 on recombination with ALV subgroup E (ALV-E) and ALV-J could induce severe hemangiomas and myelocytomas. This inference might provide a molecular basis for further research about the pathogenicity of ALV and emphasize the need for control and prevention of avian leukosis.
