Invasive lobular carcinoma of the breast is known to produce intracellular mucin and has been recognized in single-case reports to show extracellular mucin production, as well. This latter morphology is not only rare but must also be under- or misdiagnosed. The aim was to better characterize this entity. Cases of lobular cancers demonstrating extracellular mucin formation were identified in a multi-institutional effort and their clinical and morphologic features were assessed. Immunohistochemistry was used to characterize the E-cadherin-membrane complex, neuroendocrine differentiation, and to some extent, mucin formation...

Male sex differentiation is driven by 2 hormones, testosterone and anti-müllerian hormone (AMH), responsible for the regression of müllerian ducts in male fetuses. Mutations inactivating AMH or its receptor AMHRII lead to the persistent müllerian duct syndrome (PMDS) in otherwise normally virilized 46,XY males. Our objective was to review the clinical, anatomical, and molecular features of PMDS based upon a review of the literature and upon 157 personal cases. Three clinical presentations exist: bilateral cryptorchidism, unilateral cryptorchidism with contralateral hernia, and transverse testicular ectopia...

PURPOSE: Long-term survival of women with advanced-stage ovarian cancer is relatively rare. Little is known about quality of life (QOL) and survivorship concerns of these women. Here, we describe QOL of women with advanced-stage ovarian cancer surviving for 8.5 years or longer and compare women with 0-1 recurrence to those with multiple recurrences. METHODS: Participants (n=56) recruited from 5 academic medical centers and the Ovarian Cancer Research Fund Alliance completed surveys regarding QOL (FACT-O), mood (CESD), social support (SPS), physical activity (IPAQ-SF), diet, and clinical characteristics...

BACKGROUND: Two key issues in prostate cancer (PCa) that demand attention currently are the need for a more precise and minimally invasive screening test owing to the inaccuracy of prostate-specific antigen and differential diagnosis to distinguish advanced vs. indolent cancers. This continues to pose a tremendous challenge in diagnosis and prognosis of PCa and could potentially lead to overdiagnosis and overtreatment complications. Copy number variations (CNVs) in the human genome have been linked to various carcinomas including PCa...

OBJECTIVE: The prognosis from acute ischemic stroke (AIS) is worsened by poststroke medical complications. The incidence, risk factors, and outcomes of gastrointestinal bowel obstruction (GIBO) in AIS are not known. METHODS: We queried the Nationwide Inpatient Sample (2002-2011) to identify all patients with a primary diagnosis of AIS and subsets with and without a secondary diagnosis of GIBO without hernia. Multivariable analysis was utilized to identify risk factors for GIBO in AIS patients and the association between GIBO, in-hospital complications, and outcomes...

The clinical management and treatment of cervical cancer, one of the most commonly diagnosed cancers and a leading cause of cancer-related female death, remains a huge challenge for researchers and health professionals. Cervical cancer can be categorized into two major subtypes: common squamous cell carcinoma (SCC) and adenocarcinoma (AC). Although it is a relatively rare histological subtype of cervical cancer, there has been a steady increase in the incidences of AC. Therefore, new strategies to treat cervical cancer are urgently needed...

Metastases to the colon are rare and a high-frequency primary region is the stomach. In cases of metastases to the colon, the morphological type of the metastatic region is mostly the infiltrating type of poorly differentiated or undifferentiated adenocarcinoma with lymph and blood vessel invasion. A case of cancer metastasis to the transverse colon that originated from advanced gastric cancer, which shows the difficulties in the precise diagnosis of metastases to the colon, is presented. In the present case, the gastric carcinoma was determined to be an advanced infiltrative ulcerative adenocarcinoma and the colon carcinoma was determined to be a superficial depressed adenocarcinoma...

The role of parathyroid hormone (PTH) serum levels for prediction of outcome is ill defined for parathyroid cancer, which is a very rare disease. This investigation of 17 consecutive patients with parathyroid cancer, (re-)operated on at a tertiary referral center between 1994 and July 2016, with a mean follow-up of 179.6 months (15 years) aimed to clarify the suitability of PTH serum levels for prediction of clinical outcome after comprehensive operative management of parathyroid cancer. Cancer-specific mortality occurred significantly more often with the performance of sternotomy before or at first operation at this institution (80 vs...

Cryotherapy has been used in treatment of lung cancer for decades. The utility of cryotechnology in diagnosis of lung diseases is emerging and gaining popularity. Cryobiopsy (CB) of the lung, when compared with conventional transbronchial forceps lung biopsy, has proposed to have a higher diagnostic yield in interstitial lung disease by providing larger biopsy specimen and less crush artifact. Acute exacerbation of interstitial lung disease (AEILD) has been well described with surgical lung biopsies and, rarely, with conventional transbronchial forceps biopsy...

Neuroblastoma is the most common extracranial solid tumor in children and accounts for 8% to 10% of all childhood cancers. The spread of metastases is both lymphatic and hematogenous. Hematogenous route occurs most commonly in bone marrow and cortical bone; pancreatic metastases are very rare, and there are few reports about this topic in medical literature. We report the case of a 14-year-old boy who suffers a third relapse of neuroblastoma: in this patient I-MIBG confirms that lesions detected by CT were due to a relapse in pancreatic tissue and influenced subsequent therapeutic management...

PURPOSE OF REVIEW: Childhood skin cancers are relatively rare and may indicate an underlying genetic disorder. The increasing elucidation of genetic pathways is changing the diagnosis and management of genetic skin cancer susceptibility syndromes. In this review, we provide an overview of genetic conditions that predispose to skin cancer development in childhood and signs that providers should assess when evaluating affected individuals. RECENT FINDINGS: In basal cell nevus syndrome (BCNS), the patched2 (PTCH2) and suppressor of fused (SUFU) genes have been implicated in disease pathogenesis...

BACKGROUND: Sarcomas are rare and heterogeneous cancers. We assessed the contribution of DICER1 mutations to sarcoma development. METHODS: The coding region of DICER1 was sequenced in 67 sarcomas using a custom Fluidigm Access Array. The RNase III domains were Sanger sequenced in six additional sarcomas to identify hotspot DICER1 variants. RESULTS: The median age of sarcoma diagnosis was 45.7 years (range: 3 months to 87.4 years). A recurrent embryonal rhabdomyosarcoma (ERMS) of the broad ligament, first diagnosed at age 23 years, harboured biallelic pathogenic somatic DICER1 variants (1 truncating and 1 RNase IIIb missense)...

Cigarette smoking is the most frequently encountered risk factor for chronic obstructive pulmonary disease and lung cancer. The latest American Thoracic Society÷European Respiratory Society classification of idiopathic interstitial pneumonia includes two entities related to smoking habits: respiratory bronchiolitis-associated interstitial lung disease and desquamative interstitial pneumonia. The new approach to diagnosis is to combine pathological pattern with clinical and radiological data. Lung biopsy is no longer considered the "gold standard" for diagnosis, but as a part of the diagnosis, which shall be set only after the pulmonologist, radiologist and pathologist reviewed all clinical, imaging and pathological aspects...

Autoamputated ovary with mature cystic teratoma (MCT) is a rarely reported gynecologic entity with an unknown prevalence. A 34-year-old woman referred to our clinic for presumed left ovarian tumor. Pelvic examination, ultrasonography and computed tomography scan revealed a 5-cm, cystic ovarian mass with calcification and fat component, and tumor markers were as follows, cancer antigen (CA) 125; 10.4 U/mL, CA19-9; 2 U/mL. Laparoscopy was performed. The mass was identified in the left adnexal region without any ligamentous or direct connection with the pelvic organs...

Phosphatase and tensin homolog (PTEN) is the protein encoded by the PTEN gene (10q23.3). PTEN mutations are related to a variety of rare diseases referred to collectively as PTEN hamartoma tumor syndromes (PHTS), which include Cowden Syndrome, Bannayan-Riley-Ruvalcaba syndrome, Proteus Syndrome, and Proteus-like syndrome. These diseases are associated with an increased risk of malignancy and for this reason an accurate and early diagnosis is essential in order to institute cancer surveillance. PTEN is a regulator of growth and homeostasis in immune system cells, although there are limited data describing immune dysregulation caused by PTEN mutations...

Paclitaxel (PTX) is a natural alkaloid isolated from the bark of a tree, Taxus brevifolia, and is currently used to treat a variety of tumors. Recently, it has been found that low-dose PTX is a promising treatment for some cancers, presenting few side effects. However, antitumor mechanisms of low-dose PTX (<1 nM) have rarely been illuminated. Here we report a new antitumor mechanism of low-dose PTX in colorectal carcinoma cells. We treated colorectal carcinoma HCT116 cells with PTX at 0.1 and 0.3 nM for 0, 1, 2, or 3 days, and found that low-dose PTX inhibits cell growth without altering cell morphology and cell cycle...

In the United States in 2015, an estimated 74,000 new cases of bladder cancer were diagnosed and approximately 16,000 deaths were due to bladder cancer. We present a rare case of a patient with aggressive bladder cancer who presented with multiple inguinal and scrotal skin lesions that were proven to be metastatic urothelial malignancy. Bladder malignancy can involve the skin by direct tumor invasion, hematogenous routes, lymphatic spread, and direct seeding due to iatrogenic implantation. The cutaneous lesions have an extremely variable appearance, are resistant to therapies, and signify a dismal prognosis...

Stimulator of Interferon Gene (STING) is a key mediator of innate immune signaling. STING plays a pivotal role in the pathogenesis of many diseases including infectious diseases, auto-immune diseases and cancer. Many studies have been carried out recently in the field of STING-regulated pathway, however, rarely of transcriptional mechanisms. To characterize the murine STING (mSTING) promoter, we cloned a series of different nucleotide sequences of the 5'-flanking region of the mSTING gene. Transient transfection of promoter-reporter recombinant plasmids and luciferase assay illustrated the region (-77/+177) relative to the transcription start site (TSS) of the mSTING gene was sufficient for full promoter activity...

IL-1 is a pleiotropic cytokine that controls inflammation, immunity, and hemopoiesis. The major IL-1 agonistic molecules are IL-1α and IL-1β, which bind to IL-1R type I (IL-1R1) and induce similar biologic functions. The IL-1R antagonist (IL-1Ra) is a physiologic inhibitor of IL-1R1 signaling. In the tumor microenvironment, IL-1 is expressed by malignant, stromal, and infiltrating cells and supports tumor invasiveness and progression. We have shown that in the tumor microenvironment, the IL-1 agonistic molecules act different as a result of their local amounts and their compartmentalization within the producing cells...
