Pediatric inflammatory myofibroblastic tumor of the bladder with ALK-FN1 fusion successfully treated by alectinib.

An inflammatory myofibroblastic tumor (IMT) is a mesenchymal neoplasm characterized by the proliferation of myofibroblasts and inflammatory cell infiltration. Although radical resection is the only established treatment strategy for IMT, it can cause functional disorders when vital organs are affected. We describe a case of pediatric IMT of the bladder with FN1-ALK (fibronectin 1-anaplastic lymphoma kinase) fusion.

A Rare Case of Immature Sacrococcygeal Teratoma With Lymph Node Metastasis in a Neonate.

This is the first report of an immature sacrococcygeal teratoma with inguinal lymph node metastasis, providing the histologic transformation of an immature teratoma in association with chemotherapy. Incomplete tumor resection with coccygectomy was performed, and the histopathologic diagnosis was a grade 3 immature teratoma. Following the initial surgery, the residual tumors enlarged and the tumors metastasized to the inguinal lymph node, demonstrating immature teratoma without yolk sac tumor components.

Clostridium tertium Peritonitis and Bacteremia in a Neonate With Congenital Intestinal Atresia: A Case Report.

We report a 1-day-old girl who was affected by peritonitis and bacteremia caused by Clostridium tertium following perforation of congenital intestinal atresia. Splenic infarction was also suspected during C. tertium bacteremia.

Long-term functional outcome of sacrococcygeal teratoma after resection in neonates and infants: a single-center experience.

Purpose: This study aimed to evaluate the incidence and factors associated with long-term functional outcomes of sacrococcygeal teratoma (SCT) after resection in neonates and infants.

Methods: Twenty-nine patients with a minimum of 3 years of follow-up who underwent resection and were histologically diagnosed with SCTs between 1982 and 2017 at our institution were included.

Results: The median age at the time of the study was 10.

Clinical outcomes and protocol for the management of isolated congenital diaphragmatic hernia based on our prenatal risk stratification system.

Background/purpose: The aim of this study was to evaluate our prenatal risk stratification system for risk-adjusted management in fetuses with isolated congenital diaphragmatic hernia (CDH).

Methods: Ninety-four infants prenatally diagnosed with isolated CDH treated between 1998 and 2017 at our institution were included in this retrospective single-center cohort study.

Results: The patients were prenatally classified into four risk groups: Group A (n = 54), which consisted of infants with neither liver-up nor a contralateral lung-to-thorax transverse area (L/T) ratio <0.

Effective kissing stent to severe stenosis of the superior mesenteric artery replacing the common hepatic artery.

Background: Endovascular therapy (ET) for chronic mesenteric ischemia (CMI) is a effective treatment to relieve the symptoms, such as postprandial abdominal pain, food fear, and progressive weight loss. CMI is not known to be caused by rare anatomical variation of severe stenosis of the superior mesenteric artery (SMA), with replaced the common hepatic artery to the SMA. The treatment of such a rare anatomical variation using ET technique has not been discribed.

Needlescopic video-assisted wedge resection combined with the subcostal trans-diaphragmatic approach for undetermined peripheral pulmonary nodules.

Background: Reduced mortality from lung cancer by computed tomography (CT) screening facilitates the use of video-assisted thoracic surgery (VATS) lung wedge resection to obtain a definite diagnosis and to treat tiny nodules. The authors evaluated their initial experience using novel needlescopic VATS wedge resection combined with the subcostal trans-diaphragmatic (SCTD) approach for managing undetermined peripheral pulmonary nodules.

Methods: Between 2009 and 2012, 35 patients who had 36 operations underwent needlescopic VATS wedge pulmonary resection with the SCTD approach.
