RESUMO
The short- and long-term outcomes of 34 patients with refractory malignant ascites who underwent peritoneovenous shunt (PVS) therapy were retrospectively reviewed. The primary disease was gastrointestinal cancer in 31 patients and gynecologic cancer in 3 patients. Regarding performance status, 21 patients had Eastern Cooperative Oncology Group Performance Status (PS) 2 and 13 patients were PS 3;thus, many were in a poor general condition. After treatment, abdominal distention disappeared in 79.4% of patients, and appetite improved in 60.9%. The median postoperative survival time was 38 days (range, 1-294 days), and 18 patients (52.9%) were discharged. Disseminated intravascular coagulation with clinical symptoms was observed in 3 patients (8.8%), and heart failure was observed in 7 patients (20.6%). PVS therapy was useful in improving the subjective symptoms of patients with refractory malignant ascites and in enabling them to receive care at home. However, serious postoperative complications are a concern, and appropriate preoperative evaluation is necessary.

Mammary-type myofibroblastoma (MTMF) is a rare benign tumor of mesenchymal cells that occurs in the inguinal region, abdominal wall, buttocks, back, and vaginal wall. When a soft tissue mass develops in the inguinal region, there may be a risk of misdiagnosing it as an inguinal hernia, especially if it is asymptomatic. We report a rare case of mammary-type myofibroblastoma occurring in the inguinal region. The patient was a 40-year-old male who noticed swelling in the right inguinal region two years prior and consulted a nearby medical clinic. He was diagnosed with a right inguinal hernia and referred to our hospital. On physical examination, a protrusion was observed in the right inguinal region, and due to difficulty in reduction, emergency surgery was performed, suspecting intestinal incarceration. Intraoperatively, no inguinal hernia was found, but a mobile yellowish mass was identified. There were no malignant features, and the mass was excised. The pathological examination revealed mammary-type myofibroblastoma. When we examine a patient with a complaint of inguinal swelling, it is important to consider not only inguinal hernia but also other conditions such as soft tissue tumors.
RESUMO
Among immune-related adverse events, pneumonitis is relatively uncommon, and nivolumab-related pneumonitis may present with a reversed halo sign.
RESUMO
The vascular type of Ehlers-Danlos syndrome (vEDS) is a rare inherited disease of the connective tissues, and is caused by abnormal type III collagen resulting from heterogeneous mutations of the type III collagen COL3A1 gene. We herein report the case of a vEDS patient who developed a sigmoid colon perforation and was given a definitive diagnosis by a genetic and biomolecular assay. The patient demonstrated clinical manifestations caused by tissue weakness such as frequent pneumothorax events and a detached retina. During the operation, we noticed easy bruising and thin skin with visible veins on the patient's abdominal wall. Finally, a diagnosis was confirmed by the reduction of type III collagen synthesis and by the identification of a mutation in the gene for type III collagen. We conclude that it is difficult to diagnose a vEDS patient without clinical experiences and specialized genetic methods. Furthermore, all organs must be treated gently during therapy, because the tissues of vEDS patients are extremely fragile.

BACKGROUND: Although many reports indicated an association between thyroid diseases and breast cancer, such an association still remains controversial. The present study was aimed to clarify the association of thyroid diseases with the breast cancer incidence. In the patients with benign and malignant thyroid tumor or tumor-like disorders, the incidence of other malignancies was surveyed, and the frequency of thyroid cancer in patients with breast cancer was also surveyed. PATIENTS AND METHODS: Between 1982 and 2005, a total of 201 female patients received surgery for tumor or tumor-like disorders, including 65 carcinoma, 68 adenoma, 61 adenomatous goiter and 7 chronic thyroiditis cases. Their outcomes were surveyed in December 2006. Furthermore, during the same periods, 340 female patients underwent breast cancer surgery and their outcomes were also surveyed in December 2006. RESULTS: The overall incidence rate of breast cancer was 16.4% (33/201) in the patients, who received thyroid surgeries and was much higher than other malignancies: 2.0% gastric cancer, 1.0% uterine and colorectal cancer. The incidence rate of breast cancer in each disease was 13.8% for thyroid cancer, 16.2% for adenoma and 21.3% for adenomatous goiter, but no incidence for chronic thyroiditis. On the other hand, in the patients with breast cancer during the same period in our department, the frequency of thyroid cancer was only 2.1% (7/340). CONCLUSION: It appears that thyroid cancer, adenoma and adenomatous goiter were associated with the risk of breast cancer, but chronic thyroiditis was not related.

BACKGROUND: Double cancers of the biliary tract system are rare. Most of these cancers are synchronous double cancers of the gall bladder and bile duct, associated with pancreaticobiliary maljunction (PBM). Synchronous double cancers of the extrahepatic bile duct without PBM are especially rare, and only 4 cases have been reported. CASE PRESENTATION: A 78-year-old woman was admitted to our hospital for examination of hyperbilirubinemia and liver dysfunction. Contrast-enhanced abdominal computed tomography, Magnetic resonance cholangiopancreatography and endoscopic retrograde cholangiopancreatography revealed 2 stenotic regions in the common bile duct: at its junction with the cystic duct and in the distal bile duct. No findings suggested PBM, such as a markedly long common channel. The diagnosis based on endoscopic brush cytology from both stricture portions was adenocarcinoma. The patient had a pylorus-preserving pancreaticoduodenectomy with regional lymph node resection. Macroscopically, there were 2 stenotic regions at the cystic duct junction and in the distal bile duct. Microscopically, the tumor at the junction of the cystic duct was a well-to-moderately differentiated adenocarcinoma. On the other hand, the tumor of the distal bile duct was a poorly differentiated adenocarcinoma. There was no evidence of communication between these 2 cancers. CONCLUSION: Double cancers of the extrahepatic bile duct without PBM are very rare. Therefore, an accurate diagnosis prior to surgery is necessary. Furthermore, this rare condition seems to be associated with a poor prognosis.
RESUMO
Small cell carcinoma of the stomach, which is considered synonymous with neuroendocrine carcinoma, is rare. We encountered a case of mixed adenoneuroendocrine carcinoma. Gastrointestinal endoscopy revealed a type 0 IIa + IIc lesion in the stomach. Biopsy suggested well-differentiated adenocarcinoma. Endoscopic submucosal dissection was performed and gastric cancer comprising both well to moderately differentiated adenocarcinoma within the mucous membrane and small cell carcinoma invading to the submucosa with accompanying vessel invasion was found. Mixed adenoneuroendocrine carcinoma was diagnosed and the small cell carcinoma was thyroid transcription factor-1 positive. No tumor lesions were apparent in other organs, so distal gastrectomy and lymph node dissection were performed. Lymph node metastases were not observed. The patient is currently alive without recurrence. Thyroid transcription factor-1-positive gastric neuroendocrine carcinoma is very rare, and the thyroid transcription factor-1-positive rate may contribute to the prediction of prognosis and treatment selection. Accumulation of cases is thus very important.

BACKGROUND: Advanced or recurrent pancreatic cancer can sometimes cause obstruction or stenosis of the portal vein (PV), resulting in various symptoms of portal hypertension (PH), such as ascites, pancytopenia, hemorrhagic tendencies and liver dysfunction. We placed an expandable metallic stent into the PV to improve PH-associated complications and liver function. The placement of the PV stent was beneficial for administering chemotherapeutic agents and radiotherapy (RT) safely, and resulted in an improved response rate (RR) and survival. PATIENTS AND METHODS: In the present study, 14 patients with malignant portal obstruction due to advanced or recurrent pancreatic cancer received PV stent placement to manage their PH-associated symptoms. After a mini-laparotomy at the ileocecal region, the ileocecal vein was cut and an expandable metallic stent (6-8 mm in diameter and 6-8 cm in length) was inserted into the PV under image roentgenography. After placement of the PV stent, the patients received anti-coagulation treatment with heparin and biaspirin for 1-3 months. All patients received chemotherapy with UFT, cyclophosphamide (CPA) and gemcitabine (GEM), and 11 patients also received RT. RESULTS: The RR was 43% (3 complete (CR), 3 partial (PR), 3 stable disease (SD), and 5 progressive disease (PD)), and the mean survival times (MST) after the initiation of therapy or placement of the PV-stent were 12.6 and 9.5 months, respectively, while the 1-year survival rates were 54.5% and 35.1%, respectively. In the 3 CR patients, 2 died of carcinomatous ascites 13 and 21 months later, and 1 is still disease free. In the PR and SD patients, pain and PH-associated symptoms such as ascites and hyperglycemia were also improved. CONCLUSION: The placement of a PV stent is beneficial for improving PH-associated symptoms as well as facilitating chemo-RT and the efficacy of therapy.
