Langerhans cell histiocytosis (LCH) is a rare hematologic disorder that results from the clonal multiplication and accumulation of immature dendritic Langerhans cells. Its reported incidence rate varies, but is considered to be 2.6-8.9 per million children who are <15 years of age each year. It may affect any system or organ. The present study reported 4 pediatric LCH cases in order to highlight the heterogeneity of the initial presentation, and the pitfalls that may mislead clinicians and delay diagnosis...

Minimally invasive colorectal resection (MICR) for colorectal cancer (CRC) is associated with elevated levels of seven proangiogenic proteins that persist for 2-4 weeks after surgery. The proangiogenic plasma may promote tumor growth postoperatively in patients with residual cancer. To the best of our knowledge, the impact of surgery on interleukin 8 (IL-8) levels is unknown. The aim of the present study was to evaluate plasma IL-8 levels after MICR for CRC. Patients with CRC enrolled in an institutional review board-approved plasma/data bank who underwent MICR were eligible...

The World Health Organization classifies atypical chronic myeloid leukemia (aCML) as a myeloproliferative/myelodisplastic hematological disorder. The primary manifestations are leukocytosis with disgranulopoiesis, absence of basophilia and/or monocytosis, splenomegaly and absence of Philadelphia chromosome or BCR/ABL fusion. Overall 50-65% of patients demonstrate karyotypic abnormalities, although no specific cytogenetic alterations have been associated with this disease. X chromosome alterations have been rarely reported in myeloid malignancies...

Oxaliplatin is a platinum-based antineoplastic agent used in cancer chemotherapy. Oxaliplatin-induced hepatic sinusoidal obstruction syndrome (HSOS) has been reported in the context of chemotherapy for liver metastasis of colorectal cancer. However, to the best of our knowledge, there is no report of oxaliplatin-associated HSOS in patients with gastric cancer. The present study reported a patient with gastric cancer who received proximal gastrectomy and oxaliplatin-containing chemotherapy. Contrast-enhanced computed tomography revealed that liver parenchyma appeared heterogeneous and demonstrated hypoattenuation in the portal phase...

In melanoma, a number of specific genetic and genomic aberrations have been identified to be important in tumorigenesis. In particular, the mutant B-Raf proto-oncogene, Serine/Threonine kinase (BRAF) gene is the target of tailored therapy with kinase inhibitor molecules. Identification of the array of mutations in patients with melanoma will be useful in determining a genetic profile of the tumor with potential implications for treatment decisions. A rare aminoacidic insertion in codon 599 of the BRAF gene (c...

Intraductal papillary mucinous neoplasms (IPMNs) are characterized by the papillary proliferation of atypical mucinous epithelial cells in the pancreatic ductal system. There are two recurrence patterns following resection of IPMNs: Metachronous multifocal occurrence of IPMNs, and distinct pancreatic ductal adenocarcinoma (PDAC) in the remnant pancreas. Several recent studies investigated the development of distinct PDAC during follow-up evaluation of IPMNs and the incidence rate ranged from 4.5 to 8%. Thus, IMPNs may be a good predictor for the early detection of PDAC during observation or after the resection of IPMNs...

Acute lymphoblastic leukemia (ALL) has been suggested as a long-term complication in patients with β-thalassemia major (β-TM). A 12-months-old male patient was diagnosed with β-TM. The patient required a blood transfusion weekly for 2 years. At the age of 4 years, a splenectomy was performed due to massive splenomegaly and frequent transfusion requirements. The histopathological analysis of the spleen revealed extensive hemosiderosis. ALL-L1 with the T immunophenotype and without central nervous system (CNS) involvement was diagnosed when the patient was 5 years old, and treated with anti-leukemic combination chemotherapy and CNS radiotherapy...
