BACKGROUND: Tenosynovial giant cell tumor (TSGCT), also known as giant cell tumor of tendon sheath or pigmented villonodular synovitis, is the most common benign tumor of the tendon and synovium. The intra-articular diffuse type can present as a large infiltrative mass involving adjacent soft tissue and sometimes causes secondary destruction of bone, which leads to radiographic and clinical concern for malignancy. The tumor may also be purely extra-articular. CASE: Here, we report the fine needle aspiration cytology findings of 2 cases of diffuse-type TSGCT with large mononuclear cells with eccentric nuclei, finely granular cytoplasm, and a peripheral well-defined cytoplasmic rim of hemosiderin ("ladybird cells")...

Given the unique intra-peritoneal anatomic location of the adnexa, tubo-ovarian diseases can commonly spread into the peritoneal cavity. Peritoneal seeding may occur in a spectrum of adnexal conditions including infectious diseases, endometriosis, and benign or malignant primary or secondary ovarian tumors. CT is usually the imaging modality on which the concomitant involvement of the peritoneum and the ovary is depicted. The first diagnosis to be considered by the radiologist is generally peritoneal carcinomatosis from ovarian cancer but other conditions cited above have also to be borne in mind and may be suggested on the basis of careful assessment of CT findings or on further MR findings...

Cancers develop secondary to genetic and epigenetic changes that provide the cell with a survival advantage that promotes cellular immortality. Malignancy arises when tumors use mechanisms to evade detection and destruction by the immune system. Many malignancies seem to elicit an immune response, yet somehow manage to avoid destruction by the cells of the immune system. Cancers may evade this immune response by numerous mechanisms. Several targeted immune therapies are available that block some of these inhibitory signals and enhance the cell-mediated immune response...

BACKGROUND: Collision tumors are uncommon but well described clinical entities composed of distinct tumor histologies occurring within the same anatomic site. Optimal management of patients with collision tumors remains highly variable and depends on clinical characteristics such as the involved tumor types, predominant histology, as well as the extent of disease. Comprehensive genomic profiling is a means of identifying genomic alterations to suggest benefit from targeted therapy. CASE PRESENTATION: A 78-year-old woman presented to medical oncology with liver metastases occurring within the background of a 1-year history of uveal melanoma...

Recent massive parallel sequencing data have evidenced the genetic diversity and complexity of Sézary syndrome mutational landscape with TP53 alterations being the most prevalent genetic abnormality. We analyzed a cohort of 35 patients with SS and a control group of 8 patients with chronic inflammatory dermatoses. TP53 status was analyzed at different clinical stages especially in 9 patients with a past-history of mycosis fungoides (MF), coined secondary SS. TP53 mutations were only detected in 10 patients with either primary or secondary SS (29%) corresponding to point mutations, small insertions and deletions which were unique in each case...

Early malignant syphilis is a rare and severe variant of secondary syphilis. It is clinically characterized by lesions, which can suppurate and be accompanied by systemic symptoms such as high fever, asthenia, myalgia, and torpor state. We report a diabetic patient with characteristic features of the disease showing favorable evolution of the lesions after appropriate treatment.

The occurrence of multiple primary melanomas in a single individual is rare. Most commonly, malignant melanocytic lesions subsequent to the initial diagnosis of melanoma are secondary cutaneous metastases. We report a patient with gastrointestinal bleeding from gastric metastasis of cutaneous melanoma. During clinical evaluation and staging, we discovered a brain metastasis associated with 3 synchronous primary cutaneous melanomas. We suggest the research on the mutation in the cyclin-dependent kinase inhibitor 2A (CDKN2A) (INK4a) in such cases...

The DNA-alkylating cytotoxic agent cyclophosphamide (CTX) is commonly used in the clinic to treat hematological malignancies like lymphomas and leukemias as well as solid tumors, but shows dose-dependent potentially life-threatening toxicities and can induce secondary malignancies. Thus, the clinical utility of CTX would be improved if a companion drug could be identified that allows lowering the CTX dose, while maintaining or even increasing its antineoplastic therapeutic efficacy. In mouse models, high-dose CTX (300 mg/kg) is effective in treating T-lymphomas, while low dose (defined here as 100 mg/kg) is ineffective...

BACKGROUND: Organ transplant recipients (OTRs) are at an increased risk of developing a de novo malignant neoplasm compared to the general population. The primary contributor to skin cancer in all patients is sun exposure. OBJECTIVE: In this study, we aim to ascertain both OTR skin cancer awareness and photoprotection practices. METHODS: A questionnaire-based study of Saskatchewan transplant recipients. RESULTS: Nearly all respondents were aware that sun exposure is the best-known cause of skin cancer and that as an OTR, they are at increased risk of skin cancer (99...

AML1-ETO leukemia is the most common cytogenetic subtype of acute myeloid leukemia, defined by the presence of t(8;21). Remarkable progress has been achieved in understanding the molecular pathogenesis of AML1-ETO leukemia. Proteomic surveies have shown that AML-ETO forms a stable complex with several transcription factors, including E proteins. Genome-wide transcriptome and ChIP-seq analyses have revealed the genes directly regulated by AML1-ETO, such as CEBPA. Several lines of evidence suggest that AML1-ETO suppresses endogenous DNA repair in cells to promote mutagenesis, which facilitates acquisition of cooperating secondary events...

CONTEXT: Multiple endocrine neoplasia type 1 (MEN1) is a hereditary condition characterised by the predisposition to hyperplasia/tumours of endocrine glands. MEN1 related disease, moreover malignancy related to MEN1, is increasingly responsible for death in up to two-thirds of patients. Whilst patients undergo radiological and biochemical surveillance, current recommendations for radiological monitoring are based on non-prospective data with little consensus or evidence demonstrating improved outcome from this approach...

This study was designed to estimate radiation-induced secondary cancer risks from high-dose-rate (HDR) brachytherapy and external radiotherapy for patients with cervical cancer based on measurements of doses absorbed by various organs. Organ doses from HDR brachytherapy and external radiotherapy were measured using glass rod dosimeters. Doses to out-of-field organs were measured at various locations inside an anthropomorphic phantom. Brachytherapy-associated organ doses were measured using a specialized phantom that enabled applicator insertion, with the pelvis portion of the existing anthropomorphic phantom replaced by this new phantom...

Adenoviruses are common pathogens that usually cause self-limited infections. However, in the immunocompromised host they can cause severe infections involving multiple organs including the liver. A search of the pathology database at Stanford University Medical Center (1995 to 2016) identified 12 cases of adenovirus hepatitis including biopsy and autopsy specimens. There were 8 pediatric patients, 7 of which had received orthotropic liver transplants and 1 of which was receiving chemotherapy for lymphoblastic leukemia...

BACKGROUND: Out of respect for terminal patients' dignity and to decrease end-of-life suffering, patients in Taiwan can choose to sign do-not-resuscitate (DNR) orders and use hospice care when they are in a terminal condition. OBJECTIVES: To explore the trends and characteristics of hospice care utilization and DNR status among terminal cancer patients. Design and Setting/Subjects: A secondary data analysis was conducted to examine the rate of DNR orders, hospice care utilization, the survival time after DNR order, the duration of survival (DOS) after hospice care enrollment, and the rate of late referral to hospice care among patients who died from malignant cancers in a tertiary hospital in Taiwan between 2008 and 2014...

Hematological abnormalities are very common in the course of systemic lupus erythematosus (SLE). Myelofibrosis is a bone marrow disorder in which there is excessive fibrous tissue formation in the bone marrow. Various benign and malignant disorders can cause or be associated with a diffuse increase in the bone marrow reticular tissue. Some diseases such as infections, neoplasms, and autoimmune diseases may also induce bone marrow fibrosis (secondary myelofibrosis). Cytopenia from autoimmune myelofibrosis (AIMF) in SLE is a rare condition...

BACKGROUND: The historic association of Actinomyces israelii infection with intrauterine devices (IUDs) has long been recognized. In recent years, the risk of developing pelvic inflammatory disease with a copper or levonorgestrel IUD has been less than 1% in women who are low risk for sexually transmitted infections. IUD-related pelvic infections secondary to actinomyces have largely vanished from contemporary practice. CASE: A 49-year-old using a copper IUD for contraception with poorly controlled type II diabetes mellitus was admitted for suspected tubo-ovarian abscess on the basis of abdominopelvic pain, leukocytosis, and computed tomography findings...

OBJECTIVES: In long bones, cementoplasty alone does not provide sufficient stability, which may cause secondary fractures. This study reviewed the safety and efficacy of reinforced cementoplasty (RC) (percutaneous internal fixation using dedicated spindles combined with cementoplasty) for unstable malignant lesions of the cervicotrochanteric region (CTR) of the proximal femur. METHODS: Eighteen consecutive patients (nine women [50%] and nine men [50%]; mean age 55...

High-dose chemotherapy and autologous stem-cell transplantation (ASCT) is standard therapy in relapsed/refractory aggressive lymphoma. The optimal therapy of relapsed/refractory disseminated marginal-zone lymphoma (MZL) has not been defined. Limited data on ASCT in this setting suggests outcomes are similar to what is expected in follicular lymphoma. International guidelines suggest that ASCT should be considered in follicular lymphoma in second or subsequent remission, in particular in high-risk disease, or following disease transformation...
