Primary glomus tumor of the liver: A rare case report and review of the literature.

Glomus tumor is a rare neoplasm of the distal extremities. It occurs very rarely in the deep visceral organs such as stomach, lung, pancreas, ovary, and liver. Herein, we report a very rare case of glomus tumor of the liver in a 50-year-old woman presenting with abdominal mass which was diagnosed after surgery. The tumor was large and cystic; however, the morphology was similar to the ordinary soft-tissue glomus tumor. Tumor cells were reactive with CD34 and SMA. The patient's follow up failed to show any evidence of malignant behavior or tumor recurrence. This report is the third primary glomus tumor of the liver in the English literature.

Pathology of pediatric liver tumors, a single center experience from south of Iran.

Background: Pediatric hepatic malignancies are rare, accounting for 1-4% of all solid childhood tumors. The histopathology of childhood hepatic tumors guides the treatment and prognosis, and is the cornerstone for precise diagnosis. Until now, there has been no documented study on pediatric liver tumor cases from this center; in this report, we show our experience about the common types of childhood hepatic tumors during five years (2002-2007) and compare them with other studies. Materials and Methods: During five years (2002-2007), all the hepatic tumors of childhood (under 18 year-old) from the pathology file of Namazi Hospital of Shiraz University of Medical Sciences are recorded. This includes both resected specimens and biopsies. All the slides were reviewed and the pathologic diagnosis was confirmed. Results: We detected 53 liver tumor cases in children (below 18 years of age). Among these tumors, 36 (67.9%) were malignant. Male to female ratio was 1.5 to 1. Hepatoblastoma was the most common liver tumor in this age group accounting for 22 patients (41.5%). The second most common primary tumor was hepatocellular carcinoma (HCC), with five patients. Another malignant tumor was embryonal sarcoma. Benign tumors included adenoma, mesenchymal hamartoma, vascular tumors, focal nodular hyperplasia, and inflammatory pseudo tumor. There were also seven metastatic tumors during these five years. Conclusions: The spectrum of hepatic tumors in children is different from that found in the older age group (adults) and also different in different populations.

Early Postoperative Complications of Pediatric Liver Transplantation.

We reviewed records of 35 pediatric liver transplant recipients who were operated at the Shiraz Organ Transplant Center between April 1998 and April 2005 to gather demographic data, primary diagnosis, duration of hospital stay, source of graft, mortality, and surgical (vascular, biliary, fluid collection) and medical (infection, respiratory, neurological, cardiovascular, and gastrointestinal) complications. Among 23 male and 12 female pediatric liver transplant recipients (mean age: 11.8±4.9 years) with a mean hospital stay duration of 23.3±20.3 days, the postoperative complications included biliary leakage (7.20%), biliary stricture (3.10%), biliary obstruction (3.10%), pleural effusion (9.26%), lung collapse (n=1) pulmonary hemorrhage (n=1), and vascular complications of portal and hepatic vasculature (n=10, 28.6%); and infections of the peritoneum, lung, wound site, and urinary tract (n=10; 28.6%). Acute cellular rejection was documented in 6 (17.1%) recipients. Overall, 13 (37.1%) children died.
