Salivary duct carcinoma (SDC) is an aggressive form of salivary gland tumor, and SDC patients tend to be older men, more commonly in advanced stage with a poorer prognosis. Although the cytological characteristics of SDC on fine-needle aspiration cytology have been well-described at the primary site, they have not been explored in metastasis. Here we reported a case of HER2/HER3-positive metastatic SDC in the lung and pleural effusion. The patient was a man in his 50s who had undergone extended total parotidectomy in 2008...

IgG4-related disease is an inflammatory condition characterized by high levels of IgG4. It affects salivary and lacrimal glands, pancreas, lymph nodes, lungs or kidney. The diagnosis is based on identifying a histological pattern with a dense lymphocyte and plasmacyte infiltration, focal fibrosis or phlebitis, finding more than 10 IgG4 positive cells per high power field and/or IgG4/IgG ratio in plasma higher than 40%. We present a patient with Mikulicz's disease who meets histological findings required for the diagnosis of IgG4 related disease...

Herpesviruses are a large group of DNA viruses infecting mainly vertebrates. Murine gammaherpesvirus 68 (MHV68) is often used as a model in studies of the pathogenesis of clinically important human gammaherpesviruses such as Epstein-Barr virus and Kaposi's sarcoma-associated herpesvirus. This rodent virus appears to be geographically widespread; however, its natural transmission cycle is unknown. Following detection of MHV68 in field-collected ticks, including isolation of the virus from tick salivary glands and ovaries, we investigated whether MHV68 is a tick-borne virus...

BACKGROUND: Various trivalent radiometals are well suited for labeling of DOTA-conjugated variants of Glu-ureido-based prostate-specific membrane antigen (PSMA) inhibitors. The DOTA-conjugate PSMA-617 has proven high potential in PSMA radioligand therapy (PSMA-RLT) of prostate cancer as well as PET imaging when labeled with lutetium-177 and gallium-68 respectively. Considering the relatively short physical half-life of gallium-68 this positron emitter precludes prolonged acquisition periods, as required for pre-therapeutic dosimetry or intraoperative applications...

Mammary analogue secretory carcinoma (MASC) is a recently discovered salivary gland tumor described mostly in the major salivary glands and occasionally in the skin. We report a primary endobronchial tumor with histology, immunophenotype, and ETV6 rearrangement characteristic of MASC in a 62-year-old woman. The diagnosis was initially made on a transbronchial biopsy with FISH confirmation of ETV6 rearrangement. The patient underwent lobectomy demonstrating a large endobronchial mass. To our knowledge, this is the first report of MASC arising as a primary pulmonary tumor...

Adenoid cystic carcinoma (ACC) is a rare malignant tumor, mostly involving the minor salivary glands. Herein, we present a case of ACC in a 43-year-old man with symptoms of dental abscess as the initial presentation of the tumor. In spiral computed tomography (CT) scan, soft tissue mass with the erosion of maxillary sinus wall on the right side of the alveolar ridge was evident. Histopathological examination of the excised tumor with immunohistochemical studies (C-kit, Vimentin, pan-cytokeratin, p53, p63, and ki67 positive reaction) confirmed grade 2 ACC in the maxillary sinus...

A 16-year-old castrated male mongrel cat presented with swelling under the left pinna and a 3 -month history of voice change. Laryngeal endoscopy revealed circumferential oedema around the arytenoid cartilages and hypersecretion of saliva. Histopathological examination of the mass around the left ear canal was considered the primary lesion that originated from cutaneous apocrine adenocarcinoma or parotid gland adenocarcinoma, and it metastasized to the larynx, lung and medial retropharyngeal lymph nodes. This report provides new insights into feline laryngeal diseases which could result in laryngeal metastasis with slight mucosal irregularity alone and without obvious radiographic abnormalities...

Adenoid cystic carcinoma (ACC) is a rare epithelial malignancy arising from secretory glands, particularly the salivary glands. It tends to invade nerves and has a high potential for distant hematogenous metastasis, especially to the lungs, bone, liver and brain. The breast and hypophysis are not common sites of ACC metastatic disease. Herein, we report a case of ACC of the head and neck region with two unusual sites of metastases, the hypophysis and breast.

Herpesviruses have coevolved with their hosts over hundreds of millions of years and exploit fundamental features of their biology. Cytomegaloviruses (CMVs) colonize blood-borne myeloid cells, and it has been hypothesized that systemic dissemination arises from infected stem cells in bone marrow. However, poor CMV transfer by stem cell transplantation argues against this being the main reservoir. To identify alternative pathways for CMV spread, we tracked murine CMV (MCMV) colonization after mucosal entry. We show that following intranasal MCMV infection, lung CD11c(+) dendritic cells (DC) migrated sequentially to lymph nodes (LN), blood, and then salivary glands...

Lymphoepithelioma-like carcinoma of esophagus is a rare tumor with about 20 cases reported worldwide. It can involve the salivary gland, esophagus, stomach, thymus, thyroid, breast, lung, uterus, cervix, urinary bladder, and the skin. Its association with Epstein Barr virus has been postulated. We report the case of a 45-year female who had been treated for hepatitis C and esophageal tuberculosis and recovered fully from these conditions. She presented with dysphagia of 2-3 month duration. Endoscopic examination revealed narrowing of the esophageal lumen with a fungating mass at the lower end of esophagus with no extension into the stomach...

As part of further investigations into three linked haemorrhagic fever with renal syndrome (HFRS) cases in Wales and England, 21 rats from a breeding colony in Cherwell, and three rats from a household in Cheltenham were screened for hantavirus. Hantavirus RNA was detected in either the lungs and/or kidney of 17/21 (81%) of the Cherwell rats tested, higher than previously detected by blood testing alone (7/21, 33%), and in the kidneys of all three Cheltenham rats. The partial L gene sequences obtained from 10 of the Cherwell rats and the three Cheltenham rats were identical to each other and the previously reported UK Cherwell strain...

Lysozyme amyloidosis (ALys) is a rare autosomal dominant hereditary systemic amyloidosis associated with a large spectrum of clinical manifestations. ALys phenotype mainly involves the digestive tract, liver and spleen, kidneys, lymph nodes, skin, and lachrymal and salivary glands. Very recently, cardiac involvement and peripheral neuropathy associated with a new p.Leu102Ser variant of lysozyme have been documented. In the present observation, we extend the phenotypic heterogeneity of ALys to the tracheobronchial tree with histologically proven bronchial ALys-amyloid deposits...

Members of the RNaseA family are present in various tissues and secretions but their function is not well understood. Some of the RNases are proposed to participate in host defence. RNase4 and RNase5 are present in cows' milk and have antimicrobial activity. However, their presence in many tissues and secretions has not been characterised. We hypothesised that these two RNases are present in a range of tissues and secretions where they could contribute to host defence. We therefore, determined the relative abundance of RNase4 and RNase5 mRNA as well as protein levels in a range of host defence related and other tissues as well as a range of secretions in cattle, using real time PCR and western blotting...

Adenoid cystic carcinoma is a very rare malignancy commonly originating from the salivary glands of the head and neck. It is again very scantily seen in sites like the bronchus. Surgical resection is the mainstay of treatment but many a times the tumour site and size preclude a favourable outcome of surgery and the patient is advised for other forms of local treatment like Radiotherapy. Here, we present a case report of a young female with primary adenoid cystic carcinoma of the bronchus. The tumour was located in the carina and the left bronchus which was obstructing the airway resulting in collapse of the left lung, this resulted in shifting the mediastinum and abdominal structures in to the thorax...

IgG4-related diseases represent a heterogeneous group of conditions characterised by elevated serum IgG4 levels and fibrotic or sclerosing changes in the affected organs or systems accompanied by IgG4-positive plasma cells. A disease associated with IgG4 may affect virtually any organ - salivary glands, periorbital tissue, kidneys, lungs, meninges, aorta, prostate, pericardium or skin. Histopathological findings are uniform, characterised by a major lymphoplasmocytic infiltrate and the presence of IgG4-producing plasma cells, irrespective of the affected site...

Heparanase is an endoglucuronidase that uniquely cleaves the heparan sulfate side chains of heparan sulfate proteoglycans. This activity ultimately alters the structural integrity of the ECM and basement membrane that becomes more prone to cellular invasion by metastatic cancer cells and cells of the immune system. In addition, enzymatically inactive heparanase was found to facilitate the proliferation and survival of cancer cells by activation of signaling molecules such as Akt, Src, signal transducer and activation of transcription (Stat), and epidermal growth factor receptor...

Salivary gland tumours are estimated to represent approximately 3% of all head and neck tumours. About 70-80% of these neoplasms occur in the major salivary glands, with the parotid gland being the most commonly affected site. The metastasizing pleomorphic adenoma (MPA) has histological characteristics of pleomorphic adenoma, but it has the capacity to generate local recurrences and distant metastases (mainly bones, lungs, and lymph nodes). Despite the fact that some authors consider it to be a benign neoplasia, the 2015 World Health Organisation (WHO) classification of head and neck tumours considers it to be malignant...
