- Ewing sarcoma (ES) is a malignant neoplasm usually affecting the skeletal system. Extraskeletal ES is a rare tumor. To date, only 1 case of primary mesocolon ES has been previously reported in an adult. Herein, we present the first case of ES in the mesocolon in a child.
- A newborn female infant delivered after a normal pregnancy was found to have a large sacrococcygeal mass. Imaging and laboratory studies suggested this was a sacrococcygeal teratoma. On the 16th day of age, the tumor was completely removed. Histopathologic examination of the tumor showed malignant Triton tumor (MTT). Thus, we describe a female newborn without a family history of neurofibromatosis with an MTT that mimics a sacrococcygeal teratoma. To our knowledge, this is the first report of a sacrococcygeal MTT detected in a neonate.
- Ureteral injuries represent less than 1% of all traumatic genitourinary injuries. The rarity of traumatic ureteral injury is at least in part because the ureters are relatively well protected in the retroperitoneum. Ureteral injuries after blunt trauma are not common, and bilateral disruption of the ureteropelvic junction (UPJ) has only been previously reported in just one child. This is the first documented case of operative ureteral repair of bilateral complete UPJ disruption with double J ureteral stents in a child.
- A giant paraesophageal hiatal hernia with preduodenal portal vein, nonrotating gut, intrathoracic spleen, and left inferior vena cava has not been reported to date. This set of complex anomalies can have significant clinical implications. Awareness of these anomalies is essential to avoid further complications.
