Diffuse cystic lung diseases are characterized by cysts in more than one lung lobe, the cysts originating from various mechanisms, including the expansion of the distal airspaces due to airway obstruction, necrosis of the airway walls, and parenchymal destruction. The progression of these diseases is variable. One essential tool in the evaluation of these diseases is HRCT, because it improves the characterization of pulmonary cysts (including their distribution, size, and length) and the evaluation of the regularity of the cyst wall, as well as the identification of associated pulmonary and extrapulmonary lesions...

INTRODUCTION: Glandular lesions of the female genital tract (FGT) are quite uncommon compared to squamous lesions. Their cytological diagnosis is difficult because of their architectural and cytological complexity, as well as the lack of experience of many cytopathologists in this field. The aim of this study was to determine the significance of Papanicolaou (Pap) smears in the diagnosis of glandular FGT lesions. METHODOLOGY: All Pap smears reported during the period of January 2012 to December 2013 were retrieved...

Hepatocellular cancer is the most common type of primary liver cancer. Cirrhosis is the main risk factor that generates this malady. It has been proven that caloric restriction protocols and restricted feeding schedules are protective in experimental carcinogenic models. We tested the influence of a time-caloric restriction protocol (2 h of food access during the daytime for 18 weeks) in an experimental model of cirrhosis-hepatocarcinoma produced by weekly administration of diethylnitrosamine. Our results indicate that time-caloric restriction reduced hepatomegaly and prevented the increase in blood leukocytes promoted by diethylnitrosamine...

PURPOSE: To present the clinical features of patients with parotid gland metastasis, and compare the results with previously published series. Most of the relevant literature arises from case reports, while there are only few series reported, as secondary neoplastic lesions of the parotid gland are uncommon. METHODS: The medical records of patients with parotid gland metastasis, treated at the ENT Department of the University Hospital of Ferrara, between January 1st 1965 and December 31th 2014, were retrospectively reviewed...

Brown tumors seen in hyperparathyroidism are rare, non-neoplastic lesions because of abnormal bone metabolism, and they can mimic benign bone tumors or malignancy. Although biopsy is considered as the gold standard for diagnosis, it can be inconclusive. As the diagnosis of brown tumors is often challenging, a high index of suspicion is essential for diagnosis. We present a case of 21-year-old woman who presented with multiple painful bony lesions, which were initially misdiagnosed as fibrous dysplasia. Due to persistent bone pain and deterioration in her physical mobility, she was referred to tertiary care centre...

p53 deficiency, a frequent event in multiple kinds of malignancies, decreases the sensitivity of diverse targeted chemotherapeutics including the BCL-XL/BCL-2 inhibitor ABT-263. Loss of p53 function can activate mTOR complex 1 (mTORC1), which may make it a vulnerable target. Metformin has shown anti-neoplastic efficiency partially through suppressing mTORC1. However, it remains unknown whether mTORC1 activation confers ABT-263 resistance and whether metformin can overcome it in the p53-defective contexts. In this study, we for the first time demonstrated that metformin and ABT-263 synergistically elicited remarkable apoptosis through orchestrating the pro-apoptotic machineries in various p53-defective cancer cells...

While dietary polyphenols are widely recognized for cancer-preventing characteristics, the relative effectiveness and mechanisms of action of different polyphenols is not clear. In the present study, we investigated the protective effects of six different polyphenols against benzo[a]pyrene (B[a]P)-induced oxidative stress and neoplastic transformation in the Bhas 42 cell carcinogenesis assay. All of the polyphenols completely prevented the increased intracellular ROS generation by B[a]P at 12 h, and most inhibited after 3 days...

Rosai-Dorfman disease (RDD) is a rare condition similar to lymphomas, presenting with cervical lymphadenopathy in young adults. Extra-nodal involvement is relatively common but involvement of the central nervous system (CNS) is rare. Cranial RDD presents with symptoms of raised intracranial pressure, focal or generalised seizures, while spinal RDD presents with pain, peripheral neurological deficits and radiculopathy. In contrast to other similar neoplastic or degenerative conditions affecting the CNS, RDD is a benign, non-infective, granulomatous disorder...

Newcastle disease (ND) is one of the most important diseases of poultry worldwide. In the last decades, molecular research has gained a lot of new information about its causative agent, newcastledisease virus (NDV). In poultry industry, certain strains of NDV have been used for preventive vaccination for more than 60 years. NDV has also been applied to cancer patients with beneficial effects for about 50 years, but this is less well known. The molecular basis for these differential effects of NDV in birds and man have been elucidated in the last decades and are explained in this review...

CCN5/WISP-2 is an anti-invasive molecule and prevents breast cancer (BC) progression. However, it is not well understood how CCN5 prevents invasive phenotypes of BC cells. CCN5 protein expression is detected in estrogen receptor-α (ER-α) -positive normal breast epithelial cells as well as BC cells, which are weakly invasive and rarely metastasize depending on the functional status of ER-α. A unique molecular relation between CCN5 and ER-α has been established as the components of the same signaling pathway that coordinate some essential signals associated with the proliferation as well as delaying the disease progression from a non-invasive to invasive phenotypes...

Matrix metalloprotease (MMP)-mediated tissue remodeling is one of the malignant changes driving colorectal cancer. Measurement of altered MMP expression/activity is not sufficient to fully understand the effect of MMP-mediated tissue remodeling. Biomarkers are required that specifically reflect the dynamic processes of the MMP-mediated degradation of signature proteins from colorectal tissue. The aim of the present study was to profile and characterize the release of MMP-degraded type III collagen (C3M) and citrullinated and MMP-degraded vimentin (VICM) from tumor tissue and corresponding non-neoplastic adjacent tissue (NAT) in a human colorectal cancer ex vivo model...

An 11-year-old female golden retriever dog had a mass at the right corner of the upper lip, which gradually increased in size and protruded into the oral cavity. The mass was removed surgically. The cut surface of the mass was smooth, whitish and solid, and covered by the oral mucosal membrane. Histopathologically, the mass consisted mainly of reticular pattern of short spindle cells that stained positively for cytokeratin AE1/AE3, α-smooth muscle actin and p63, suggestive of a myoepithelial cell phenotype...

Adult-onset Still's disease (AOSD) is a rare systemic auto-inflammatory disorder (SAID). Although the pathogenesis of the disease is complex and far from being fully understood, recent progresses in pathophysiological knowledge have paved the way to new diagnostic approaches. Indeed, AOSD diagnosis can be a real challenge, owing to its infrequency, and to the lack of specificity of the principal clinical features (high fever, arthralgia or arthritis, skin rash) and laboratory findings (elevated acute phase reactants, hyperleukocytosis ≥ 10,000 cells/mm(3) with neutrophils ≥80%)...

Multicystic peritoneal mesothelioma (MCPM) is a rare neoplasm, predominantly affecting female patients during their reproductive years. The lesion is usually distributed diffusely in the abdomen and pelvis, but the peritoneum of the pelvic organs is the most common site. MCPM is composed of fluid-filled translucent cysts, connected by varying amounts of fibrous tissue, and lined by a layer of mesothelial cells. Because of the rarity of this disease, the pathogenesis and natural history of MCPM remain poorly understood and continuously debated...

The Hippo pathway regulates cell proliferation and apoptosis and it has been noted that loss of critical components of this pathway can lead to uncontrolled cell growth. Yes-associated protein (YAP) is an important component of this Hippo pathway because YAP is the nuclear effector of the Hippo tumor suppressor pathway and it is crucial for the response to oxidative stress induced by cellular process and by different xenobiotics, including arsenic. It has been proposed that YAP dysregulation can contribute to a malignant cellular phenotype acting as both a tumor suppressor and an oncogene...

Intussusception is commonly seen in children but is rare in adults and represents only 5% of all intussusceptions causing 1% of intestinal obstructions. More than 50% of these intussusceptions in adults are due to intestinal neoplasms, including malignant lymphoma, e.g., Burkitt lymphoma. These lymphomas are more common in human immunodeficiency virus (HIV)-positive patients than in the general population. We present a case of a young male who was diagnosed with HIV when he developed intestinal obstruction and intussusception secondary to Burkitt lymphoma...

Chronic thyroiditis may present a focal lesion, often-palpable abnormality, simulating nodular disease. The number and morphology of the Hürthle cells (HC) vary in the thyroid aspirate. Distinguishing between neoplastic and non-neoplastic HC lesions is difficult when using the fine-needle aspiration cytology (FNAC). We present the case of a 46-year-old female with a large right nodular goiter and hypothyroidism and high titer of anti-thyroid peroxidase antibody (TPO). The thyroid ultrasound showed a large well-defined nodule (more than 6...
