    背景:肺泡软组织肉瘤是一种罕见的软组织肿瘤,大多位于四肢的肌肉或深层软组织。在极少数情况下,这种肿瘤在腹部或骨盆的深层组织中发展。
    方法:在本案例报告中,我们描述了一例46岁的男性,他发展为原发性脾肺泡软组织肉瘤。肿瘤表现出典型的形态肺泡方面,以及免疫组织化学谱,特别是TFE3核染色。分子生物学中ASPSCR1外显子7::TFE3外显子6融合转录本的检测和FISH中TFE3重排的检测证实了诊断。
    结论:我们描述了第一例原发性脾肺泡软组织肉瘤,这再次质疑这种罕见肿瘤的起源细胞。
    BACKGROUND: Alveolar soft part sarcoma is a rare tumour of soft tissues, mostly localized in muscles or deep soft tissues of the extremities. In rare occasions, this tumour develops in deep tissues of the abdomen or pelvis.
    METHODS: In this case report, we described the case of a 46 year old man who developed a primary splenic alveolar soft part sarcoma. The tumour displayed typical morphological alveolar aspect, as well as immunohistochemical profile notably TFE3 nuclear staining. Detection of ASPSCR1 Exon 7::TFE3 Exon 6 fusion transcript in molecular biology and TFE3 rearrangement in FISH confirmed the diagnosis.
    CONCLUSIONS: We described the first case of primary splenic alveolar soft part sarcoma, which questions once again the cell of origin of this rare tumour.

    脾梗塞是一种以脾脏血流受损为特征的医学疾病,导致部分或完全的器官梗塞。这种情况通常在血栓形成风险增加的患者中观察到,如真性红细胞增多症(PV)。一名40岁的女性患者表现出疲劳,弱点,和肿大的脾脏,进一步的测试显示血红蛋白水平升高,白细胞,和血小板。骨髓活检和JackII突变阳性证实了PV的诊断。患者后来出现门静脉高压,静脉曲张,和脾梗死.本病例报告旨在提高对PV潜在并发症的认识,并强调早期干预以预防脾梗死等严重后果的重要性。此外,它强调了脾切除术在治疗PV相关并发症中的作用.
    Splenic infarction is a medical condition characterized by compromised blood flow to the spleen, resulting in partial or complete organ infarction. This condition is commonly observed in patients with an increased risk of thrombosis, such as those with Polycythemia Vera (PV). A 40-year-old female patient presented with fatigue, weakness, and an enlarged spleen, further tests revealed elevated levels of hemoglobin, white blood cells, and platelets. A bone marrow biopsy and positive Jack II mutations confirmed the diagnosis of PV. The patient later developed portal hypertension, varices, and splenic infarction. This case report aims to raise awareness about the potential complications of PV and emphasizes the importance of early intervention to prevent serious consequences such as splenic infarction. Additionally, it highlights the role of splenectomy in managing complications associated with PV.

    BACKGROUND: Cancer of cervix often fails locally and/or within the pelvis. One to two percent of cervical squamous cell carcinoma patients have lung metastases at presentation, and 5-35% develop pulmonary metastases later on. Common sites of metastases are the liver, bone, and bowel. We report a rare case presentation of cervical squamous cell cancer where heterochronous metastasis occurred in the skin, spleen, and pancreas without loco-regional recurrence and skipping of visceral organs such as the lung, liver, and brain.
    METHODS: A 55-year-old, postmenopausal lady presented with a complaint of bleeding of the vagina for 2 months duration. Cervical biopsy revealed squamous cell carcinoma of the cervix, and she was staged as a case of FIGO stage IIIB. She received external beam-beam radiotherapy of 50 Gy in 25 fractions along with concurrent weekly cisplatin at 35 mg/m2 followed by 3 fractions of intracavitary brachytherapy of 6 Gy each. After 30 months of follow-up, she presented with a skin lesion of 6 × 5 cm2 in the infrascapular region for 2 months duration. Biopsy revealed metastatic squamous cell carcinoma. Her metastatic work-up revealed no other lesions. Palliative radiotherapy to local site of 8 Gy in single fraction was delivered. The lesion disappeared within 4 weeks. She was given 6 cycles of cisplatin and paclitaxel salvage chemotherapy. After 30 months of follow-up, she presented with a skin lesion of 6 × 5 cm2 in the infrascapular region. Biopsy revealed metastatic squamous cell carcinoma. Her metastatic work-up revealed no other lesions. Palliative radiotherapy to the local site was planned, and a dose of 8 Gy in a single fraction was delivered. The lesion disappeared within 4 weeks. She was given 6 cycles of cisplatin and paclitaxel salvage chemotherapy. Six months after the completion of salvage therapy, she reported with the complaints of recurrent bouts of hematemesis and melena. Her CECT scan revealed 2 × 1.5 cm2 growth in the body of the pancreas and a subcentric splenic hilum node. She underwent open splenectomy with distal pancreatectomy. Histopathology report showed metastatic infiltration in pancreatic tissue by squamous cell carcinoma and one metastatic node in the splenic hilum. Post-treatment, 6 months, the patient was asymptomatic with no recurrence.
    CONCLUSIONS: This is a rare heterochronous metastatic presentation of cervical cancer without loco-regional recurrence and visceral organs such as the lung, liver, and brain. The optimal treatment remains undefined for these patients. Multimodality treatment is necessary to manage the patients.

    BACKGROUND: Portomesenteric vein thrombosis is a rare but documented complication of laparoscopic surgery. This rare complication is currently being encountered more frequently with the increase in the rates of laparoscopic bariatric surgery procedures being performed worldwide.
    METHODS: A retrospective analysis was performed on all bariatric procedures performed in our center between July 2012 & December 2017 to identify cases complicated by portomesenteric venous thrombosis. The cases were compared in terms of operative details, patient presentation, diagnosis, patient risk factors for developing thrombosis, demographics and thrombophilia analysis & subsequent treatment and prognosis.
    RESULTS: A total of 1030 bariatric procedures were performed between July 2012 & December 2017. Portomesenteric venous thrombosis complicated 3 of these cases (0.29%). Two of these cases had underwent a laparoscopic sleeve gastrectomy while the third had underwent a gastric band removal and a conversion to a single anastomosis gastric bypass. Amongst these patients, 2 were female while 1 was male with an average BMI 38.9 kg/m2. Only one of these patients was a smoker while none of them tested positive for thrombophilias. The diagnosis of portomesenteric venous thrombosis was confirmed with a contrast CT of the abdomen as all patients were re-admitted between 4-20 days post operatively after being discharged on postoperative day 2. All three cases were managed with systemic anticoagulants and none underwent invasive procedures or were re-explored surgically. All were subsequently discharged in good condition.
    CONCLUSIONS: Portomesenteric venous thrombosis is an uncommon yet potentially fatal complication of bariatric surgery. A high index of suspicion, early diagnosis and subsequent adequate management is required. Based on this case series and the potential risk of portomesenteric venous thrombosis, we altered our clinical practice to include a 1 week course of low molecular weight heparin to be administered to all patients after discharge.

    UNASSIGNED: Splenic rupture after laparoscopic surgery is a very rare complication. In this study, we report a case of a splenic laceration that occurred during a laparoscopic gastrostomy tube placement. The theorized mechanism in this case was acute disruption of a peri-splenic hematoma.
    UNASSIGNED: A 64-year-old African-American male presented after a motor vehicle accident with multiple injuries and was admitted to a surgical intensive care unit, where he declined from ICU days 6 through 11. The patient underwent tracheostomy and laparoscopic gastrostomy tube placement given his significant neurologic deficits. Intraoperatively, the patient developed hypotension, leading to the discovery of hemoperitoneum and necessitating an emergent open splenectomy.
    UNASSIGNED: Splenic rupture following laparoscopic procedures is a very rare phenomenon. In this case, we believe the splenic rupture was secondary to an acute disruption of a previously hemostatic splenic hematoma involving the abdominal wall during creation of capnoperitoneum.

    Primary splenic angiosarcoma carries a poor prognosis and is among the rarest forms of malignancy. An overwhelming majority of patients with splenic angiosarcoma will develop metastases. However, osseous metastatic disease is rare. We present an 83 year old hispanic female who was diagnosed with primary splenic angiosarcoma on bone marrow biopsy performed for a hematologic workup. We highlight key historical, laboratory, imaging, and pathological features of splenic angiosarcoma. The synthesis of both imaging features and clinical history is essential for establishing early diagnosis in these patients.

    Spleen is an unusual location for hydatid cyst. Here we report a case of primary splenic hydatid cyst in a 41-yr-old Iranian woman from Yasuj, southwest of Iran. The patient had been admitted to Shahid Beheshti Hospital because of abdominal pain. Abdominal sonography revealed a hypoechoic lesion of 150 X 130 mm in the spleen, suggestive of hydatid cyst. Splenectomy was performed for the patient and surgical interventions revealed a hydatid cyst occupying most of splenic parenchyma. She was discharged on the 5 day of her operation. Postoperative diagnosis and confirmation of hydatid cyst was done by histopathological, molecular and serological approaches. Histopathological evaluation revealed the classical laminated layer of hydatid cyst. DNA was extracted from a part of cyst and PCR amplified. Sequencing and analysis of PCR product revealed that the isolate has the most similarity with G1 strain of Echinococcus granulosus. Patient\'s serum was positive for IgG anti-hydatid cyst antibodies, using antigen-B ELISA.

    Splenic hamartoma (SH) is a rare benign tumor usually detected accidentally, which is composed of an aberrant mixture of normal splenic elements. Here, we report a case of 54-year-old man who presented with symptomatic multinodular SH and was admitted initially for thrombocytopenia and anemia. Physical examination revealed that the patients had an anemic appearance and palpable spleen, extending 10 cm below the costal margin. Preoperative ultrasound and computed tomography (CT) indicated splenomegaly with multinodular lesions. On enhanced CT scanning, during the arterial phase, the lesions demonstrated inhomogeneous enhancement, and in the portal phase the lesions were more hyperdense than the splenic parenchyma. The images were highly suggestive of a metastatic tumor. Splenectomy was performed 1 wk later. The tumor was eventually diagnosed as SH according to the morphological features and immunohistochemical detection, by which CD34 was positive in lining cells and some spindle cells, vimentin was positive in the tumor, factor-VIII-related antigen was positive multifocally in lining cells, and smooth muscle actin was positive in some spindle cells. Thrombocytopenia and anemia were cured after splenectomy.
