OBJECTIVES: Approximately 1 % of all malignant solid tumours of the head and neck area are metastases from primary tumours beneath the clavicles. The aim of this study was to analyse the distribution of primary tumours since meta-analyses might have been biased due to the usually extraordinary character of case reports. MATERIALS AND METHODS: All patient files from 1970 to 2012 from the Oral and Maxillofacial Surgery unit at a University Hospital were analysed regarding the existence of metastases to the head and neck area from distant primaries...

Background: Although the role of epigenetic abnormalities has been studied for several years in cancer genesis and development, epigenetic-targeting drugs have historically failed to demonstrate efficacy in solid malignancies. However, successful targeting of chromatin remodeling deficiencies, histone writers and histone reader alterations has been achieved very recently using biomarker-driven and mechanism-based approaches. Epigenetic targeting is now one of the most active areas in drug development and could represent novel therapeutic opportunity for up to 25% of all solid tumors...

A young adult, female, free-ranging Japanese raccoon dog ( Nyctereutes procyonoides viverrinus) with scabies infection was found dead as a result of traumatic injuries presumed to reflect vehicular trauma. Necropsy showed a large solid mass located on the left ovarian region, occupying a third of the abdominal cavity. Histologically, the mass contained complex tissues derived from three germinal layers, with areas of cuboidal or columnar epithelium, keratinized squamous epithelium, bone, cartilage, and adipose tissue...

BACKGROUND: Taxanes are drugs used in various chemotherapeutical protocols to treat solid tumors. They have multiple systemic adverse effects, such as bone marrow suppression, alopecia, nausea, and vomiting, and may rarely cause ocular symptoms. In the past decade, a few reported cases have shown the occurrence of a cystoid macular edema with significant visual loss after the use of a taxane-based chemotherapy. The aim of this study was to compare the central macular thickness (CMT) before and after the initiation of a taxane-based therapy in visually asymptomatic patients and to elucidate the possible impact of these drugs on the vision of cancer patients...

Primary leiomyosarcoma arising from the ovarian vein is extremely rare, with only 10 cases reported in the literature. We report on a case of leiomyosarcoma of the left ovarian vein in a 67-year-old woman who presented with abdominal discomfort. Pelvic ultrasound revealed a large, solid, irregular mass in close relation to the left ovary. The patient subsequently underwent a total hysterectomy with bilateral salpingo-oophorectomy. Histologically, the tumor was composed of interlacing fascicles of spindle cells with abundant eosinophilic cytoplasm, hyperchromatic nuclei, and prominent nucleoli...

Microcystic stromal tumors (MCST), first described in 2009 by Irving et al., are rare ovarian neoplasms. The entity was introduced into the 2014 WHO classification of tumors of female reproductive organs in the group of sex cord-stromal tumors, which is rather heterogeneous. We studied three cases of ovarian tumor with the characteristic morphological features and immunohistochemical marker profiles of MCST. The three tumors showed micro, and macrocystic patterns with solid areas, and were composed of small round to spindle-shaped cells, without atypia...

NHERF1 is an adaptor protein expressed in the apical membrane of polarized epithelia, which interacts with the EZRIN-Radixin-Moesin (ERM) family of proteins connecting signaling pathways to the cell cytoskeleton. NHERF1 and EZRIN cooperate in the maintenance of the apical microvilli in polarized epithelial cells. In several types of cancers, NHERF1 and EZRIN are displaced from the apical compartment to the cytoplasm and nuclei of cancer cells. At the present, the distribution of NHERF1 in ovarian tumors is not well known...

Primary ovarian carcinoid tumors are exceptionally rare entities accounting for approximately 0.1% of all ovarian neoplasms. This report describes a primary ovarian neuroendocrine tumor arising in association with a mature cystic teratoma in a 65 year-old woman. Macroscopically, the unilateral adnexal tumor was composed of cystic, solid and mucinous elements which resolved into a dual component lesion histologically. The majority of the tumor displayed an organoid architecture with mild to moderate pleomorphism and no discernible mitotic activity, while approximately 10% consisted of sheets and groups of cells with highly pleomorphic nuclei, necrosis and occasional mitoses...

Coccidioidomycosis is a common infection in the desert southwestern USA; approximately 3 % of healthy persons in Arizona alone become infected annually. Coccidioidomycosis may be severe in immunocompromised persons, but experience among patients with solid organ cancer has not been fully described. Therefore, we aimed to describe the clinical courses of patients whose cancers were complicated by coccidioidomycosis at our institution, which is located in an area with endemic Coccidioides. To do so, we conducted a retrospective review from January 1, 2000, through December 31, 2014, of all patients with breast, colorectal, or ovarian cancer whose cancer courses were complicated by coccidioidomycosis...

INTRODUCTION: Over recent years our understanding of DNA damage repair has evolved leading to an expansion of therapies attempting to exploit DNA damage repair deficiencies across multiple solid tumours. Gastric cancer has been identified as a tumour where a subgroup of patients demonstrates deficiencies in the homologous recombination pathway providing a potential novel treatment approach for this poor prognosis disease. AREA COVERED: This review provides an overview of DNA damage repair and how this has been targeted to date in other tumour types exploiting the concept of synthetic lethality...
