In patients without systemic manifestations of tuberculosis, isolated brainstem tuberculous abscesses are infrequently observed. The present study reports a rare case of two cystic tuberculous abscesses involving the dorsal aspect of the medulla oblongata in an otherwise healthy 14-year-old Chinese girl, whose primary complaint was respiratory distress. These lesions were successfully treated using a microsurgical excision approach and anti-tuberculosis therapy. Although rare, tuberculous abscesses should be considered in the differential diagnosis of isolated cystic brainstem lesions...

The clinical and histopathological distinction between keratoacanthoma (KA) and squamous cell carcinoma (SCC) is essential, but frequently difficult to make. The utility of CK17 and Ki-67 expression in distinguishing between KA and SCC was investigated. Immunohistochemical staining patterns for CK17 and Ki-67 were evaluated in 24 KA and 27 SCC cases. The pattern of staining was evaluated as central, peripheral or diffuse, according to the basal/peripheral and suprabasal/central cell staining of tumor lobules...

Breast cancer is the second most common cause of mortality in women; therefore, the identification of novel putative markers is required to improve its diagnosis and prognosis. Selenium is known to protect mammary epithelial cells from oxidative DNA damage, and to inhibit the initiation phase of carcinogenesis by stimulating DNA repair and apoptosis regulation. Consequently, the present study has focused attention on the selenoprotein family and their involvement in breast cancer. The present study performed a global analysis of the seleno-transcriptome expression in human breast cancer MCF-7 and MDA-MB231 cell lines compared with healthy breast MCF-10A cells using reverse transcription-quantitative polymerase chain reaction...

The diagnosis of neuroendocrine differentiation (NED) is made primarily on the basis of ultrastructure and/or immunohistochemistry (IHC). Synaptophysin (Syn) and chromogranin A (CgA) are two important frequently used NED markers in colorectal cancer (CRC). The association between NED and the prognosis of stage II CRC remains controversial. Administration of adjuvant chemotherapy remains challenging for stage II CRC. Identification of reliable factors that improve the selection of patients with stage II CRC at high risk following surgery is of great importance...

A 72-year-old female was referred for further evaluation of epigastralgia. Abdominal contrast computed tomography revealed numerous tumors in the two lobes of the liver. Liver biopsy and immunohistochemical staining revealed that the tumor cells were positive for factor VIII-associated antigen, platelet endothelial cell adhesion molecule 1 and human hematopoietic progenitor cell antigen, concordant with a diagnosis of hepatic epithelioid hemangioendothelioma (HEH). To elucidate the etiology of HEH, particularly the microRNA (miRNA) profiles, tissue samples obtained from normal and tumor tissues were analyzed using a miRNA array system...

Sarcomatoid urothelial carcinoma of the urinary tract is associated with poor prognosis. The majority of sarcomatoid urothelial carcinomas are found in the urinary bladder, while a small minority have been shown to arise from the ureter. In the present case, a 72-year-old male patient was diagnosed with sarcomatoid urothelial carcinoma with chondrosarcomatous differentiation of the left ureter, and subsequently underwent nephroureterectomy and retroperitoneal lymph node dissection. Two lymph nodes from the renal hilum and one paraaortic lymph node were also found to have metastatic involvement; however, the patient refused to receive chemotherapy or radiotherapy and succumbed to bone and omentum metastasis at 6 months after the initial diagnosis...

Neutropenia in the setting of acute hematological malignancies may impact disease prognosis, thus affecting therapy dose intensity. This is often due to chemotherapy-induced aplasia as well as to the disease itself. However, chronic neutropenia deserves further investigation, as the management of reversible concomitant causes may avoid treatment delay. The present study describes a case of an acute promyelocytic leukemia patient with chronic severe neutropenia of multifactorial origin, including acute leukemia itself, chemotherapy, autoimmune activation with anti-platelets and anti-neutrophil antibodies positivity, and the rare association of large granular lymphocyte (LGL) expansion...

Within neuropsychology, the term dispersion refers to the degree of variation in performance between different cognitive domains for an individual. Previous studies have demonstrated that cognitively normal individuals displaying higher dispersion are at an increased risk for progressing to mild cognitive impairment (MCI) and Alzheimer's disease (AD). Therefore, we determined 1) whether increased dispersion in older adults was associated with amyloid plaques and neurofibrillary tangles (NFTs) and 2) whether increased cognitive dispersion accurately differentiated MCI and AD from non-cognitively impaired (NCI) individuals...

Myelolipoma is a kind of rare benign tumour composed of mature adipocytes and hemopoietic elements, and is most often found in the adrenal glands. Primary mediastinal myelolipoma (PMM) more rarely happens and has no definite symptoms, and mediastinal masses are usually found in chest examination. The patients normally receive a surgical resection and have a favorable prognosis after postoperative pathological diagnosis. Here, we present the case of PMM, which was resected via video-assisted thoracic surgery (VATS), and investigate recent correlative literatures to summarize its etiology, histopathology, differential diagnosis and therapeutic method...

BACKGROUND: Pulmonary inflammatory myofibroblastic tumor (IMT) has been considered as a synonym for inflammatory pseudotumor (IPT) for a long time. Recent studies have indicated that IMT and IgG4-related IPT are distinct diseases. However, no consensus criteria have been recommended. Here we propose a set of criteria for the differential diagnosis. METHODS: Twenty-six archived IMT and IgG4-related IPT samples were examined for histological characteristics and the expression of IgG, IgG4, SMA and ALK-1...

Colorectal cancer (CRC) is one of the leading causes of cancer related deaths in the world. Many oncogenes and tumor suppressor genes are involved in the development of CRC. MicroRNAs (miRNAs) are a class of small, non-coding, endogenous RNAs in animals and plants. Recent studies have shown that miRNAs are associated with the mediation process of tumorigenesis, including inflammation, cell cycle, stress response, differentiation, apoptosis, migration, and invasion in cancer. These miRNAs have been linked to the development of CRC and recently studied as new potential biomarkers in the diagnosis and treatment for CRC...

Warthin-like papillary thyroid carcinoma (WLPTC) is a rare morphological variant of papillary thyroid carcinoma which mimics various benign and malignant lesions on thyroid aspiration cytology. As correct cytological diagnosis is the cornerstone for appropriate patient management, awareness of the salient cytomorphological characteristics of this tumor is essential. Here, we present cytological features of a case of WLPTC along with discussion of the common differential diagnoses and a brief review of the literature to ascertain the most consistent cytological findings of WLPTC...

BACKGROUND: Malignant pleural mesothelioma is a rare tumor with a dismal prognosis, usually presenting with recurrent effusions. However, the majority of malignant pleural effusions are due to lung adenocarcinoma (AdC). The distinction between these tumors has considerable therapeutic and medicolegal implications and can be very challenging both histologically and cytologically. Appropriate immunohistochemistry (IHC) is required to support the diagnosis. MicroRNA (miRNA) expression analysis could be a viable diagnostic tool for distinguishing between these tumors...

Pediatric melanoma, although rare, is the most common skin cancer in children. Our current knowledge on pediatric melanoma incidence trends is expanding, as several studies have addressed this issue with conflicting results. Known risk factors for pediatric melanoma include family history of melanoma, a previous history of malignancy, large congenital nevi, numerous melanocytic nevi, sunburns, increased UV exposure and a sun-sensitive phenotype. In younger children melanoma more often presents with atypical features, such as a changing, amelanotic or uniformly colored, often bleeding lesion, not fulfilling in most cases the conventional ABCDE criteria...

BACKGROUND: Discrepancy between informants (parents and teachers) in severity ratings of core symptoms commonly arise when assessing autism spectrum disorder (ASD). Whether such discrepancy yields unique information about the ASD phenotype and its clinical correlates has not been examined. We examined whether degree of discrepancy between parent and teacher ASD symptom ratings defines discrete, clinically meaningful subgroups of youth with ASD using an efficient, cost-effective procedure...

An 8-year-old female Boxer was examined for acute onset of seizures. On magnetic resonance imaging (MRI), an intra-axial mass with imaging features consistent with glioma was observed in the right cerebral hemisphere. A defect in the temporal bone adjacent to the mass was observed. Postmortem computed tomography (CT) confirmed temporal bone osteolysis and necropsy demonstrated a glioblastoma with associated calvarial erosion. Although occasionally described in human medicine, to our knowledge, this is the first description of a brain glioma causing calvarial erosion in a dog...

Background: Maternal alcohol use during pregnancy has repeatedly been associated with development of attention-deficit hyperactivity disorder (ADHD) in the offspring. It is, however not known whether this reflects a direct casual intra-uterine effect or a non-causal relationship due to confounding. We used three different approaches to control for measured and unmeasured confounding: statistical adjustment for covariates, negative control comparison against maternal pre-pregnancy alcohol use, and comparison among differentially exposed siblings...
