Background: The worldwide increase in road traffic crashes and use of firearms has increased the incidence of duodenal injuries. Upper gastrointestinal radiological studies and computed tomography (CT) in resource settings may lead to the diagnosis of blunt duodenal injury. Exploratory laparotomy remains the ultimate diagnostic test if a high suspicion of duodenal injury continues in the face of absent or equivocal radiographic signs. Although the majority of duodenal injuries may be managed by simple repair, high-risk duodenal injuries are followed by a high incidence of suture line dehiscence and should be treated by duodenal diversion.
Case presentation: We report a case of a failed primary repair of a blunt injury to the second part of the duodenum (D2) in a 24-year-old African man. This was successfully managed by a tube duodenostomy, a bypass gastrojejunostomy and a feeding jejunostomy in a low resource setting.
Conclusions: Detailed knowledge of the available operative choices in duodenal injury and their correct application is important. When duodenal repair is needed, conservative repair techniques over complex reconstructions should be utilised. The technique of tube duodenostomy can be successfully applied to cases of large defects in the second part of the duodenum (D2), failed previous repair attempts and with defects caused by different aetiology. It may remain especially useful as a damage-control procedure in patients with multiple injuries, significant comorbidities and/or haemodynamic instability.

Background: Breast implant-associated anaplastic large-cell lymphoma (BIA-ALCL) is a rare malignancy. Many cases of BIA-ALCL are identified based on the presence of late-onset effusion and/or masses. Importantly, the United States Food and Drug Administration noted that in all cases diagnosed in patients with textured implants, the patients either had a history of mixed implantation of smooth and textured devices or no clinical history was supplied for review. In Japan, the first case of BIA-ALCL was reported in 2019, and we encountered the third case in Japan in December 2021. There have been a total of five cases of BIA-ALCL previously reported at Japanese academic conferences (Japan Oncoplastic Breast Surgery Society. http://jopbs.umin.jp/medical/index.html ), of which only the first case has been published. Unlike the first case, this patient had clinical features that were highly suggestive of the postoperative chest wall recurrence of breast cancer, with a mass and rash on the skin.
Case presentation: The patient was a 45-year-old woman who had undergone breast reconstruction after breast cancer surgery of the right breast 8 years previously. The patient presented with a mass and skin rash inside the inframammary area, and we suspected a damaged silicone breast implant (SBI) or chest wall recurrence. We examined the mass by a core needle biopsy and made a pathological diagnosis of BIA-ALCL. Imaging findings suggested internal thoracic lymph node swelling and lymphoma infiltration beyond the capsule but no metastatic lesions (cStage III). After en bloc resection of the SBI and lymphoma, adjuvant systemic therapy was performed.
Conclusion: We encountered the third case of BIA-ALCL in Japan. This was a case with clinically advanced stage of disease; however, the BIA-ALCL was found to be in remission.

Background: Ehlers-Danlos syndrome (EDS) is a rare inherited connective tissue disease characterized by hyperextensibility of the skin and joints and tissue fragility of the skin and blood vessels, Vascular EDS is the most severe form of EDS, with abnormal arterial fragility. There have been no reports of breast cancer occurring in patients with vascular EDS. Here, we report here a very rare case of breast cancer in a patient with vascular EDS.
Case presentation: A 46-year-old woman with vascular EDS underwent partial left mastectomy and sentinel lymph node biopsy for left breast cancer (cStage 0) detected by medical examination. The final pathological diagnosis was invasive ductal carcinoma of the breast (pStage IA) [hormone receptor-positive, HER2 score 2 equivocal (FISH-positive), Ki-67LI 18%, luminal-HER2 type]. BluePrint was submitted as an aid in determining the postoperative treatment strategy, BluePrint Molecular Subtype HER2-type. However, the 10-year breast cancer mortality risk using Predict was low (5%). After consultation with the patient, the decision was made to administer postoperative radiation to the preserved breast along with hormone therapy only. There was no delay in postoperative wound healing, and the patient was free of metastatic recurrence for 9 months after surgery.
Conclusion: We performed surgery, postoperative radiotherapy, and hormonal therapy in a breast cancer patient with vascular EDS without major complications.

Background: Automatic stapling devices are commonly utilized in pulmonary resections, including sublobar segmentectomy. Large tumors can develop around the staple line, posing challenges in distinguishing them from cancer recurrence or inflammatory changes. In this report, we present two cases of symptomatic staple granulomatous lesion effectively managed with medications.
Case presentation: A 74-year-old man presented with a persistent cough and sputum production six years post-segmentectomy for a hamartoma in the left upper lobe. Chest computed tomography (CT) revealed a large tumor around the staple line. Laboratory investigations and bronchoscopic examination revealed no malignancy. The patient received corticosteroids and a cyclooxygenase-2 inhibitor; despite experiencing adverse reactions to steroids, both tumor size and respiratory symptoms were significantly reduced. The second case involved a 78-year-old woman who underwent pulmonary resection for suspected lung cancer. Despite a non-malignant tumor diagnosis, she reported a cough six months post-surgery. Chest CT revealed extensive shadow around the surgical staple, which was diagnosed as mycobacterium granuloma. Low-dose erythromycin induced inflammatory changes but effectively reduced the lesion.
Conclusions: Granulomatous lesions around the staple can be effectively managed with medication, and monitoring the treatment response proves valuable in distinguishing them from tumor recurrence post-pulmonary resection.

Background: Supine hypotension syndrome (SHS) has been reported to occur due to compression by a giant tumor such as ovarian tumor. We herein report a case of retroperitoneal ganglioneuroma with SHS treated with laparoscopic resection.
Case presentation: The patient was an 11-year-old male with right-sided abdominal pain. He had a pale complexion and tachycardia while falling asleep. Computed tomography (CT) and magnetic resonance imaging (MRI) showed a giant mass lesion (60 × 35 mm) with compression of the inferior vena cava (IVC) and duodenum ventrally and the right kidney caudally. The IVC was flattened by mass compression. Abdominal ultrasonography (US) revealed narrowing of the IVC due to the mass and accelerated blood flow after IVC stenosis in the supine and left lateral recumbent position. His pale complexion and tachycardia while falling asleep was thought to be due to decreased venous return caused by the tumor compressing the IVC, resulting hypotension. 123I-MIBG scintigraphy revealed no abnormal findings. Tumor markers were normal. He was diagnosed with SHS due to a right adrenal gland tumor. The tumor compressed the IVC from the dorsal side, and hemostasis was expected to be difficult during bleeding. Therefore, a guidewire was inserted from the right femoral vein into the IVC for emergency balloon insertion during bleeding. A laparoscopic tumor resection was performed. A histopathological examination confirmed the diagnosis of primary retroperitoneal ganglioneuroma.
Conclusions: The treatment of symptomatic retroperitoneal tumors requires a multidisciplinary approach.

Background: Papillary thyroid carcinoma rarely undergoes anaplastic transformation. Some risk factors for anaplastic transformation of thyroid cancer are known, but such transformation is difficult to predict in practice. We report a case demonstrating elevations of neutrophil-to-lymphocyte ratio (NLR) and C-reactive protein (CRP) over time as a precursor to anaplastic transformation of thyroid carcinoma.
Case presentation: The patient was an 89 year-old woman with a history of chronic aortic dissection. She was referred to our department after her local doctor detected thyroid nodules. She had previously been found to have multinodular goiter and enlarged left cervical lymph nodes on computed tomography. Her chief complaint was cervical discomfort and hoarseness. Blood tests revealed: white blood cells (WBCs), 4900 /µL; CRP, 0.29 mg/dL; neutrophils, 64.4%; and lymphocytes, 25.4%. A 21 mm mass was identified in the upper left lobe. Left III (16 mm) and left VI (16 mm) lymph node were enlarged on ultrasonography. Fine-needle aspiration cytology diagnosed malignant papillary carcinoma. However, due to the advanced age and medical history of the patient, a non-surgical policy was implemented. The primary tumor grew to 4 cm in diameter by 9 months after diagnosis, and blood tests showed: WBC, 7700 /µL; CRP, 0.18 mg/dL; neutrophils, 65.3%; and lymphocytes, 22.3%. By 10 months after diagnosis, the tumor had increased rapidly in diameter to 8 cm, with blood tests showing: WBC, 6500 /µL; CRP, 1.01 mg/dL; neutrophils, 68.2%; and lymphocytes, 19.3%. Anaplastic transformation of papillary thyroid carcinoma was diagnosed, and the patient was placed on treatment under a policy of best supportive care. Multiple lung metastases appeared 11 months after diagnosis, and blood test results showed: WBC, 13,300 /μL; CRP, 11.28 mg/dL; neutrophils, 93.6%; and lymphocytes, 2.3%. Unfortunately, the patient died of disease progression 63 days after identification of undifferentiated metastasis.
Conclusions: Chances to see the natural history of anaplastic transformation of thyroid cancer are rare. Elevations in NLR and CRP over time may be precursors to anaplastic transformation.

Background: Esophageal carcinosarcoma (ECS) is a relatively rare malignancy, accounting for < 1% of all esophageal cancers. Its etiopathogenesis remains unknown. This study analyzed the genomic abnormalities in sarcomatous tumors from two patients undergoing subtotal esophagectomy using whole genome sequencing to elucidate the key characteristics of ECS.
Case presentation: We identified TP53 driver mutations, copy number gains in 11q13 (including CCND1), and Apolipoprotein B mRNA editing enzyme catalytic polypeptide (APOBEC) signature enrichment in both ECS patients. Along with common genetic abnormalities, we identified CDKN2A driver mutations in case 1 and RAC1, NOTCH1, and TTC28 as novel fusion gene partners of MECOM in case 2. Notably, we detected germline pathogenic variant in Fanconi anemia (FA) complementation group I (FANCI) and group G (FANCG), which are involved in repairing DNA double-strand breaks by homologous recombination, for the first time, in ECS blood samples. These germline variants were truncating-type, Lys1221fs of FANCI (rs1567179036) for case 1 and Gln365Ter of FANCG (rs121434426) for case 2. We also identified somatic changes in cancer-associated pathways, such as PI3K/Akt/mTOR, cell cycle, and NOTCH signaling pathways, and structural chromosomal defects such as chromosome doubling.
Conclusions: Our findings indicate that therapeutic drugs targeting the activation signal or FA pathway might be effective in treating ECS, however, their therapeutic significance should be elucidated in future studies.
背景:食管癌肉瘤(ECS)是一种相对罕见的恶性肿瘤,多见于病例:我们在两名食管癌患者中均发现了 TP53 驱动基因突变、11q13(包括 CCND1)拷贝数增高和载脂蛋白 B mRNA 编辑酶催化多肽(APOBEC)特征富集。除了常见的遗传异常,我们还在病例 1 中发现了 CDKN2A 驱动基因突变,在病例 2 中发现了 RAC1、NOTCH1 和 TTC28 作为 MECOM 的新型融合基因伙伴。值得注意的是,我们首次在 ECS 血液样本中检测到范可尼贫血(FA)补体 I 组(FANCI)和 G 组(FANCG)的种系致病变体,这些变体通过同源重组参与 DNA 双链断裂的修复。这些种系变异是截断型的,病例 1 是 FANCI 的 Lys1221fs(rs1567179036),病例 2 是 FANCG 的 Gln365Ter(rs121434426)。我们还发现了癌症相关通路(如 PI3K/Akt/mTOR、细胞周期和 NOTCH 信号通路)的体细胞变化,以及染色体结构缺陷(如染色体加倍):我们的研究结果表明,针对激活信号或FA通路的治疗药物可能对治疗ECS有效,但其治疗意义还需在今后的研究中进一步阐明。

Background: Spontaneous mesenteric hematoma is a rare condition that is diagnosed when clinical and pathological findings do not identify an obvious causative disease. Various treatment options for spontaneous mesenteric hematoma exist; however, there are no clear treatment criteria. Herein, we report a case of spontaneous mesenteric hematoma that was successfully treated surgically and discuss the optimum treatment strategy based on similar cases.
Case presentation: A 63-year-old man with abdominal persisting for 3 days presented to our hospital after going into shock without any triggers. The patient had a history of atrial fibrillation, stroke, and an aneurysm, and was receiving antithrombotic therapy. Abdominal contrast-enhanced computed tomography revealed a mass structure within the sigmoid mesentery, which was suspected to be a hematoma. The patient was admitted to the hospital for follow-up observation after initial infusion and vital stabilization. However, the following day, the patient developed acute generalized peritonitis with necrosis of the sigmoid colon; therefore, emergency Hartmann's surgery was performed. Intraoperative and histopathological examinations revealed no evidence of bleeding.
Conclusion: Spontaneous mesenteric hematomas tend to be associated with intestinal necrosis and may require surgical treatment with bowel resection owing to the difficulty in identifying the responsible vessel. Moreover, our results suggest that the presence of antithrombotic therapy may be an important factor affecting spontaneous mesenteric hematoma development.

Background: Adenosquamous carcinoma of the pancreas (ASCP) accounts for only 1-4% of all pancreatic exocrine cancers and has a particularly poor prognosis. The efficacy of chemotherapy for ASCP remains unknown because of the small number of cases, and few studies have evaluated conversion-intended chemotherapy.
Case presentation: A 76-year-old woman was referred to our hospital because of epigastric pain and nausea. A preoperative contrast-enhanced multidetector row computed tomography (MDCT) scan revealed a 17 × 17 mm low-density tumor with an ill-defined margin at the arterial phase in the pancreatic head. The tumor involved the common hepatic artery, left hepatic artery bifurcated from the common hepatic artery, and gastroduodenal artery, and was in contact with the portal vein. Fluorodeoxyglucose-positron emission tomography (FDG-PET) showed an uptake in the pancreatic head but no evidence of distant metastasis. The tumor was diagnosed as an adenocarcinoma of the pancreatic head and staged unresectable because the common and left hepatic arteries were involved. Hence, the patient underwent seven courses of conversion-intended chemotherapy using gemcitabine and nab-paclitaxel for pancreatic ductal adenocarcinoma over 7 months. After chemotherapy, the tumor shrank to 10 × 10 mm on contrast-enhanced MDCT. Consequently, the boundary between the tumor and major vessels of the common and left hepatic arteries and the portal vein became clear, and the involvement of the arteries with the tumor was evaluated to be released. The contact of the tumor to the portal vein also reduced to less than half the circumference of the portal vein. FDG-PET showed decreased accumulation in the tumor. Hence, the tumor was judged resectable, and pancreaticoduodenectomy was performed. The tumor and major blood vessels were easily dissected and R0 resection was achieved. The patient experienced no major complications and was discharged on postoperative day 28. The tumor was revealed as ASCP via pathological examination. The patient is alive and recurrence-free seven months after surgery. This is the first report of successful R0 resection for an initially unresectable ASCP following conversion-intended chemotherapy using gemcitabine and nab-paclitaxel regimen.
Conclusions: Conversion-intended chemotherapy using gemcitabine and nab-paclitaxel regimen may be effective for ASCP.

Background: Bronchial bifurcation abnormalities are often discovered incidentally on chest computed tomography or bronchoscopy. As this condition is asymptomatic, it has little effect on the disease course of patients with lung cancer. However, this abnormality must be considered when performing lung resection.
Case presentation: Patient 1 was a 73-year-old man with suspected simultaneous triple lung cancers [cT1c (3) N0M0, Stage IA3] in the right and left upper lobes. He was initially scheduled to undergo right upper lobectomy and systematic nodal dissection. Chest computed tomography revealed a displaced B3 that arose from the right middle lobe bronchus. V1+2 was transected first, followed by the superior truncus of the pulmonary artery, and B1+2, respectively. After the branches of V3 were ligated, B3 was identified smoothly. Finally, the incomplete interlobar fissure between the upper and middle lobes was separated using an auto-stapler. No vascular abnormalities were observed. Patient 2 was a 62-year-old woman with suspected lung cancer (cT1cN0M0, Stage IA3) in the right upper lobe, and was scheduled to undergo right upper lobectomy and lobe-specific nodal dissection. Chest computed tomography revealed a right top pulmonary vein and a displaced B1 that arose from the right main bronchus independently. Because V1+3 was resected simultaneously during upper and middle lobe resection during robot-assisted thoracic surgery, the procedure was cool-converted to video-assisted thoracic surgery. An independently A1 was observed, followed by A2b and A3, which branched off as a common stem. A right top pulmonary vein was smoothly detected. Each blood vessel was transected using an auto-stapler. B2+3 was transected first using an auto-stapler, followed by B1.
Conclusions: The displaced anomalous bronchus is often accompanied by pulmonary arterial or venous abnormalities and an incomplete interlobar fissure. A "hilum first, fissure last" technique is often useful. Preoperative evaluation and surgical planning are important.
