RESUMEN
An 85-year-old woman had been followed up by a local doctor for a cystic lesion of the right breast for 3 years. The lesion was frequently treated with fine needle drainage due to its tendency to slowly increase in size over time. Following the latest drainage of the cystic lesion, the patient became aware of intermittent bleeding from the drainage site, and thus, visited our emergency department. At the time of her hospital visit, the patient had a tense fist-sized mass centered on the C area of the right breast, and the mass was eruptively bleeding from the puncture scar. We performed fine needle drainage and obtained approximately 150 cc of bloody fluid. The bleeding lesion was compressed with a sink and chest band and the patient was hospitalized. When we released the pressure the next day, her right breast was as tense as the initial presentation and purpura were observed. Based on the patient's hematological findings, which showed worsening anemia, we suspected intermittent bleeding from an intracystic tumor. The patient underwent right mastectomy three days after admission. Pathologically, a diagnosis of cholesterol granuloma of the breast was confirmed.

In recent years, bridge to surgery(BTS), in which surgery is performed after colorectal stenting for obstructive colorectal cancer, has gradually become popular, and laparoscopic surgery is also a treatment option. From January 2020 to December 2022, we retrospectively evaluated clinicopathological factors in 18 colorectal cancer cases who underwent radical resection after colorectal stenting. We found no difference in patient background, histopathological factors, primary anastomosis rate, stoma creation rate, operative time, postoperative complication rate and length of hospital stay between the laparoscopic surgery(L)and open surgery(O)groups. Blood loss was significantly lower in group L. In T4 patients, laparoscopic surgery after colorectal stenting can be safely performed, but conversion to open surgery may be necessary. Surgery after colorectal stenting should be performed based on preoperative accurate imaging and sufficient experience.

BACKGROUND: Intravascular papillary endothelial hyperplasia (IPEH) is a reactive lesion histopathologically characterized by papillary growth of vascular endothelial cells. IPEH is most commonly found in the skin and subcutaneous tissues of the head, neck, and extremities. Furthermore, it has been reported to occur in oral surgery, but its occurrence in bone is extremely rare. CASE PRESENTATION: We present the case of a 77-year-old man with a chief complaint of left knee arthralgia. The knee joint X-ray showed Kellgren-Lawrence grade 4 osteoarthritis and a mass lesion with decreased permeability within the bone in the medial part of the proximal tibia. Computerized tomography (CT) scan of the left knee showed a localized mass in the left proximal tibia with clear margins and granular internal calcification. The preoperative diagnosis was left knee osteoarthritis and a benign tumor of the left proximal tibia (enchondroma or hemangioma). The patient requested surgical treatment, so left total knee arthroplasty (TKA) and resection of the tumor were performed. The pathology revealed a rare intraosseous IPEH with marked calcification. CONCLUSIONS: Since intraosseous IPEH could not be considered from the clinical findings, the pathological diagnosis was the decisive factor. This report showed the world's first case of intraosseous IPEH with marked calcification. Similar to the calcification of intraosseous hemangiomas, we considered the possibility that, in IPEH, the thrombus may fibrosis and organize in concentric circles, causing necrosis at the center and resulting in calcification. TKA was performed on the degenerative knee joint with IPEH, and a good patient outcome was obtained.

A 72-year-old man was presented with anemia and diagnosed with sigmoid colon cancer by colonoscopy. CT showed a soft tissue density around the retroperitoneum, leading to the diagnosis of retroperitoneal fibrosis. Stenosis of left ureter, inferior mesenteric artery, and left colic artery due to the soft tissues were detected. Sigmoidectomy and retroperitoneal biopsy were performed, and colorectal anastomosis was completed after confirming the intestinal blood flow by ICG fluorescence angiography. In retroperitoneal fibrosis, identifying blood vessels intraoperatively can be difficult. ICG fluorescence angiography is useful for reliable anastomosis in colorectal cancer surgery with retroperitoneal fibrosis.

Hepatocellular carcinoma is associated with a relatively high rate of paraneoplastic syndrome, but the frequency of erythrocytosis is low. We report a case of hepatocellular carcinoma with preoperative erythrocytosis and hypererythropoietinemia. The case is a 50-year-old man who has been cured by interferon treatment for hepatitis C 20 years ago(SVR). He visited our hospital with the complaint of right hypochondrial pain, and was diagnosed with hepatocellular carcinoma, which occupied S8/5/7 of the liver, and showed erythrocytosis and high erythropoietin(Epo)as tumor-related symptoms. A right hepatic lobectomy was performed, and the patient was discharged 13 days after the operation. The red blood cell count and Epo were normalized immediately after the operation. One year and 2 months after the operation, multiple lung metastases recurred, and chemotherapy is currently underway. Hepatocellular carcinoma with erythrocytosis and hypererythropoietinemia has been reported to have a poor prognosis, and multimodal treatment and strict surveillance are considered necessary.

OBJECTIVE: Fibroblast growth factor receptor 2 (FGFR2) has been proposed as a novel druggable target in unresectable gastric cancer. FGFR2 alteration has been reported as associated with poor prognosis even in patients with gastric cancer who received systemic chemotherapy. This study aimed to evaluate the frequency of FGFR2 overexpression and gene amplification in clinical specimens from Japanese patients with recurrent or unresectable gastric cancer. METHODS: This observational study enrolled patients who were histologically or cytologically confirmed with unresectable HER2-negative or unknown gastric or gastroesophageal junctional adenocarcinoma treated with at least one previous chemotherapy. FGFR2 overexpression and gene amplification in the specimens were evaluated by immunohistochemical staining and fluorescence in situ hybridization methods, respectively. RESULTS: In a total of 173 eligible cases, FGFR2 immunohistochemistry score was evaluated as 0, 1, 2, 3 and 4 for 20, 80, 35, 28 and 10 cases, respectively. In 151 evaluable cases with FGFR2 immunohistochemistry scores of 1-4, FGFR2 copy number expressed as fluorescence in situ hybridization signals were detected as <4, ≥4 < 10 and ≥10 copies for 123, 16 and 12 cases, respectively. FGFR2 copy number showed an increasing tendency along with higher FGFR2 immunohistochemistry scores in the corresponding specimen. The response rate and time to treatment failure for first line chemotherapy did not have any obvious relationship to FGFR2 immunohistochemistry score and FGFR2 copy number. CONCLUSIONS: Although FGFR2 overexpression and gene amplification were shown in Japanese patients with unresectable gastric cancer, these alterations did not impact the effects of cytotoxic agents as first line chemotherapy.

Tumor lysis syndrome (TLS) is an oncologic emergency caused by release of intracellular tumor components due to massive tumor lysis and is rare in patients with hepatocellular carcinoma (HCC). We describe a case of TLS with rupture of HCC induced by lenvatinib in a patient with advanced HCC. A 72-year-old man who presented with right upper abdominal pain was diagnosed as having advanced HCC with a high tumor burden by contrast-enhanced computed tomography and percutaneous hepatic tumor biopsy. He was started on lenvatinib 12 mg once daily when his tumor progressed despite one-shot hepatic arterial infusion chemotherapy. On day 2 of treatment with lenvatinib, he developed severe upper abdominal pain and was diagnosed as having TLS with HCC rupture by laboratory tests and contrast-enhanced computed tomography. Urgent treatment with transarterial embolization, hemodialysis, and blood transfusion therapy was successful. The patient was then restarted on oral lenvatinib at a reduced dose without recurrence of TLS. TLS is a rare potential complication of lenvatinib in patients with advanced HCC and a high tumor burden.

BACKGROUND AND AIMS: Hepatobiliary phase-hypointense nodules without arterial phase hyperenhancement (HHNs without APHE) on gadolinium-ethoxybenzyl-diethylenetriamine-enhanced magnetic resonance imaging (Gd-EOB-DTPA-enhanced MRI) are considered to be dysplastic nodules or early hepatocellular carcinoma (HCC) and have high risk of undergoing malignant transformation and progression to hypervascular HCC. The aim of this study was to evaluate the clinical outcome of HHNs without APHE diagnosed by Gd-EOB-DTPA-enhanced MRI before the eradication of HCV by direct-acting antiviral agents (DAAs). METHODS: We retrospectively investigated 221 consecutive patients with HCV infection who were treated with DAAs. Thirty patients with 65 HHNs without APHE were enrolled in a sustained virologic response (SVR) cohort and 22 with 43 HHNs without APHE who did not receive DAAs or had failed HCV eradication therapy were enrolled in a non-SVR cohort. Fifty-seven percent of patients in the SVR group and 64% of those in the non-SVR group had a history of HCC. The primary endpoint of this study was the development of hypervascular HCC from HHNs without APHE detected on imaging. The cumulative incidence and relative risk of progression to hypervascular HCC in relation to clinical characteristics were compared between the two cohorts. RESULTS: The 2-year cumulative incidence of progression to hypervascular HCC was 8.5 and 21.9% in the SVR and non-SVR cohorts, respectively. There was a significant reduction in progression of HHNs without APHE to HCC after the eradication of HCV (p = 0.022, log-rank test). Multivariate Cox regression analysis identified hyperintensity on T2-weighted images (relative risk 14.699, p < 0.001) and achieving SVR (relative risk 0.290, p = 0.043) as independent factors associated with the risk of HCC. During follow-up, 6 (9.2%) of the HHNs without APHE in the SVR cohort became undetectable on hepatocyte-phase images. CONCLUSIONS: Eradication of HCV by DAAs could reduce the hypervascularization rate of HHNs without APHE, and some of these nodules disappeared.
RESUMEN
BACKGROUND: A growing body of evidence suggests that inflammatory response markers such as the neutrophil-to-lymphocyte ratio (NLR) and lymphocyte-to-monocyte ratio (LMR) are associated with outcomes of various malignancies. However, no study has reported the prognostic value of NLR and LMR in patients with distal bile duct cancer (DBDC) to date. We investigated the prognostic significance of these inflammatory markers in patients with DBDC who underwent radical resection. METHODS: The study included 40 patients diagnosed with DBDC who underwent pancreaticoduodenectomy at Narita Red Cross Hospital between January 2000 and December 2017. The cutoff values for these markers were determined by receiver operating characteristic curve analysis. Survival curves are estimated for each group in the study considered separately using the Kaplan-Meier method. The association between overall survival (OS) and the NLR, LMR, and other prognostic factors was investigated using log-rank test and multivariate Cox proportional hazards regression analysis. RESULTS: Corresponding to the point with the maximum combined sensitivity and specificity on the ROC curve, the best cutoff value for NLR and LMR was determined to be 3.14 and 4.55, respectively. Most clinicopathological factors were not associated with the NLR and LMR based on these cutoff values. However, serum albumin levels were associated with both the NLR and LMR (P = 0.011 and P = 0.023, respectively), and serum carbohydrate antigen 19-9 (CA 19-9) levels were also associated with the LMR (P = 0.030). Univariate analysis showed that a high NLR (P < 0.001), low LMR (P = 0.002), hypoalbuminemia (P = 0.004), high serum CA 19-9 levels (P = 0.008), and lymph node metastasis (P = 0.033) were significantly associated with poor survival rates. Multivariate analysis showed that a high NLR (hazard ratio 5.799, 95% confidence interval 1.188-28.32, P = 0.030) and a low LMR (hazard ratio 4.837, 95% confidence interval 1.826-2.331, P = 0.025) were independent prognostic factors for OS. CONCLUSION: Both NLR and LMR may serve as significant independent preoperative prognostic indicators of disease in patients with DBDC who undergo radical resection.

Objective We aimed to examine the dynamics of serum Wisteria floribunda agglutinin-positive human Mac-2-binding protein glycosylation isomer (M2BPGi) in patients with acute liver injury. Methods Serum M2BPGi levels at the time of the diagnosis (n=77) and normalization of the serum alanine aminotransferase (ALT) level (n=26) were examined retrospectively. The difference in the serum M2BPGi level according to the etiology, and the correlations with other laboratory parameters were evaluated. Results The serum M2BPGi level at the time of the diagnosis was increased in 59 of 77 patients [2.3 cutoff index (COI); range, 0.31-11.1 COI] and was significantly decreased at the time of serum ALT normalization (0.68 COI; range, 0.15-1.87 COI; p<0.0001). The serum M2BPGi level was positively correlated with the duration for which serum ALT normalization was achieved (n=46, Spearman rho=0.53, p<0.0001). A multivariate analysis identified total bilirubin (T-bil), albumin, ALT, alkaline phosphatase, and etiology (e.g., drug-induced liver injury or etiology unknown) as independent factors for increased serum M2BPGi. In patients with infectious mononucleosis, the serum M2BPGi level was higher relative to the degree of increase of serum ALT or T-bil levels in comparison to other etiologies. Conclusion The serum M2BPGi level in patients with acute liver injury reflects the magnitude and duration of liver injury. However, it should be noted that the degree of increase of serum M2BPGi in patients with acute liver injury may differ according to the etiology.

A 60-year-old man with an unruptured cerebral aneurysm and family history of moyamoya disease was admitted to our hospital with epigastric pain since the previous day. Serum levels of pancreatic enzyme were elevated and abdominal contrast-enhanced computed tomography showed localized enlargement of the pancreatic tail in the arterial phase and revealed numerous areas of fine mesh-like vascular hyperplasia consistent with an enlarged pancreatic tail. We diagnosed pancreatic arteriovenous malformation (P-AVM) with acute pancreatitis. Furthermore, in the pancreatic body, endoscopic ultrasonography showed lobularity (honeycombing type) and hyperechoic foci (non-shadowing), which suggests chronic pancreatitis. Acute management was performed with conservative treatment including administration of replacement fluids and proteolytic enzyme inhibitor. Distal pancreatectomy for P-AVM was performed because P-AVM is associated with acute pancreatitis recurrence, development of portal hypertension, progression of chronic pancreatitis, and refractory duodenal bleeding. Histological findings on the resected specimens revealed the anastomosis of abnormal arteries and veins, which suggested P-AVM. In addition, inflammation accompanied by fat necrosis due to ischemic infarction in the pancreatic tail, which suggested acute pancreatitis, and mild fibrosis in the pancreatic body, which suggested chronic pancreatitis, were shown. Although P-AVM is associated with various complications, symptomatic P-AVM should be considered a chronic and progressive disease.

A 37-year-old obese man who was a social drinker was admitted to our hospital to undergo a detailed examination for liver injury with anti-mitochondrial antibody positivity. Abdominal ultrasonography revealed moderate fatty liver. A histological analysis showed steatosis of approximately 30% of the hepatocytes, focal necrosis, a few ballooning hepatocytes and lobular inflammation suggestive of steatohepatitis, epithelioid granuloma and irregularity of the sequence of the bile duct epithelium accompanied by lymphocyte infiltration suggestive of chronic cholangitis. He was diagnosed with non-alcoholic steatohepatitis complicated with primary biliary cholangitis. His liver injury was improved by weight loss and high-dose ursodeoxycholic acid treatment.

Since diffuse hepatic hemangiomatosis (DHH) is an extremely rare disease especially in adults, the etiology and natural course of adult-onset DHH has not been well understood. We report a case of DHH complicated with multiple organic dysfunction and Kasabach-Merritt syndrome (KMS) in an 83-year-old female. She presented with mild abdominal distension and laboratory findings revealed thrombocytopenia and abnormal coagulation, indicating disseminated intravascular coagulation (DIC). Enhanced computed tomography revealed diffuse, hypodense hepatic nodules with delayed enhancement involving the whole liver, and multiple hypodense splenic legions. To obtain a definitive diagnosis, laparoscopic-guided biopsy was performed. Histological findings revealed irregularly dilated non-anastomotic vascular spaces, which were lined with flat endothelial cells without cellular atypia. We diagnosed this as DHH complicated with splenic lesions and KMS. Although the patient was treated with symptomatic treatment, such as anti-coagulation therapy, hemangiomatous lesions, especially in the spleen, progressed rapidly, leading to worsening of DIC. Finally, the patient died of multiple organ failure at 12 months after diagnosis. A postmortem examination demonstrated diffuse hemangiomatosis of not only the liver and spleen, but also the adrenal glands and bone marrow. Despite no malignant histologically, DHH can be fatal if it progresses rapidly within a short period of time.

The patient was a 59-year-old man who was hospitalized with diarrhea and general malaise. Massive ascites and systemic edema were observed upon initial physical examination. Blood test findings showed anemia, hepatic dysfunction, and increased tumor marker levels. Imaging examination revealed the presence of a primary tumor associated with stenosis, extending from the rectosigmoid junction to the upper rectum, multiple liver metastases, and massive ascites. Pathological examination indicated well-differentiated adenocarcinoma. A treatment strategy comprising colostomy and chemotherapy was implemented. Administration of 6 courses of mFOLFOX6 plus panitumumab(Pmab)and 4 courses of FOLFIRI plus Pmab led to marked shrinkage of the primary tumor and liver metastases and disappearance of the ascites. Chemotherapy was discontinued at the request of the patient. The patient developed melena after 2 years. Colonoscopy revealed enlargement of the rectal cancer, and surgical intervention was indicated. We adopted a treatment policy of 2-stage resection, and low anterior resection was performed. The liver was partially resected 3 months later. Hepatic recurrence was observed 9 months after the liver resection, and repeated resection of the liver was performed. An aggressive treatment approach can lead to improved prognosis even in cases involving multiple liver metastases and cancerous ascites.

The overlap of multiple liver diseases can cause the disease activity and severity to worsen rapidly in some cases. We rarely see patients with non-alcoholic steatohepatitis (NASH) with overlapping autoimmune hepatitis (AIH). A 64-year-old woman who had been prescribed oral drugs to treat diabetes and hypertension (metformin 500 mg/day and voglibose 0.9 mg/day, and termisartan 40 mg/day and amlodipine 5 mg/day, respectively) was diagnosed with NASH with histological confirmation. At 68 years of age, her liver injury worsened with an IgG of 2,871 mg/dL and a high serum anti-nuclear antibody (ANA) level of 2,560. We repeated the liver biopsy, which revealed NASH and mild interface hepatitis with some lobular focal necrosis consisting of overlapping AIH. Therefore, she was treated with 30 mg of prednisolone daily. The treatment led to an improvement in her IgG levels and ANA in the serum and an improvement in the histology results.

BACKGROUND: Recently, morbidities due to primary cytomegalovirus (CMV) infection have increased in young Japanese adults because of decreased anti-CMV antibodies in them. CMV infections are typically resolved naturally in immunocompetent individuals, and complications rarely occur. Here we present the case of an immunocompetent adult with CMV infection complicated by splenic infarctions and an esophageal ulcer. CASE REPORT: A 37-year-old male complaining of a prolonged fever and liver injury was admitted to hospital for a closed examination. The patient had general malaise and mild appetite loss but no abdominal pain. Symptoms of infectious mononucleosis, including liver injury, appearance of atypical lymphocytes in the blood, and hepatosplenomegaly, were observed. A primary CMV infection was confirmed by CMV-IgM positive and CMV-IgG negative serological tests. Enhanced abdominal computed tomography confirmed hepatitis and splenic infarction, and an upper gastrointestinal endoscopy revealed an esophageal ulcer. The patient exhibited no predisposing risk factors for thrombosis, and he was diagnosed with splenic infarctions associated with CMV infection. Because the patient was immunocompetent, he underwent symptomatic therapy without antiviral or anticoagulant therapies. The treatment improved his overall condition. Including the present case, only 11 cases of CMV infections with splenic infarction in immunocompetent individuals have been reported. Contrary to what is observed in immunocompromised hosts, upper gastrointestinal lesions with CMV infection are rare in immunocompetent individuals. The esophageal lesion observed in our patient was a typical punched-out ulcer. The immunohistochemical staining of the tissue biopsies revealed that the ulcer was associated with CMV. CONCLUSION: Although splenic infarctions and esophageal ulcers are rare, they should be considered as potential complications accompanying CMV infection in immunocompetent individuals. The administration of symptomatic therapy should be considered even when the patient is immunocompetent.

A 40-year-old man complaining of abdominal distention was referred to our hospital. Computed tomography of the abdomen demonstrated a very large abdominal mass with fat and calcification. The size of the mass rapidly increased from 30cm to 40cm over two weeks. The tumor was removed and diagnosed by pathological examination to be a retroperitoneal mature cystic teratoma that contained a 40-cm long, mature intestinal tract-like cyst, together with bone marrow and fat. The rapid growth of the tumor may have been caused by an increased secretion in the cyst.

A 45-year-old female who complained of high fever and jaundice was admitted to our hospital for severe liver failure. She had a history of treatment for chronic hepatitis B, which had not been observed for a long time. She was diagnosed with liver failure due to severe hyperthyroidism due to untreated Basedow disease and not due to acute exacerbation of chronic hepatitis B. She was successfully treated with artificial liver adjuvant therapy and total thyroidectomy. Hyperthyroidism should, therefore, be considered as one of the possible causes of acute-on-chronic liver failure.

Ascites accompanying a malignancy is often refractory to conventional treatment with saline diuretics, making it difficult to control. We administered a new diuretic, Tolvaptan, to 10 individuals with malignancy and heart failure accompanied by ascites, which was refractory to saline diuretics, and assessed its efficacy and adverse events. We observed a significant reduction in abdominal distension following 2 weeks of Tolvaptan administration. However, we also observed significant increases in serum potassium, urea nitrogen, and creatinine levels, but no serious adverse events. This suggests that Tolvaptan may also be effective as treatment for ascites.

Reports of conversion in cases of locally advanced colorectal cancer have been increasing. Here, we present 2 cases in which curative resection of locally advanced rectal cancer accompanied by intestinal obstruction was achieved after establishing a stoma and administering chemotherapy. The first case was of a 46-year-old male patient diagnosed with upper rectal cancer and intestinal obstruction. Because of a high level of retroperitoneal invasion, after establishing a sigmoid colostomy, 13 courses of mFOLFOX6 plus Pmab were administered. Around 6 months after the initial surgery, low anterior resection for rectal cancer and surgery to close the stoma were performed. Fourteen days after curative resection, the patient was discharged from the hospital. The second case was of a 66-year-old male patient with a circumferential tumor extending from Rs to R, accompanied by right ureter infiltration and sub-intestinal obstruction. After establishing a sigmoid colostomy, 11 courses of mFOLFOX6 plus Pmab were administered. Five months after the initial surgery, anterior resection of the rectum and surgery to close the stoma were performed. Twenty days after curative resection, the patient was released from the hospital. No recurrences have been detected in either case.
