PURPOSE: To disclose, using an ex vivo study, the histopathological mechanism behind in vivo thickening of the endothelium/Descemet membrane complex (En/DM) observed in rejected corneal grafts (RCGs). METHODS: Descemet membrane (DM), endothelium, and retrocorneal membranes make up the total En/DM thickness. These layers are not differentiable by high-definition optical coherence tomography; therefore, the source of thickening is unclear from an in vivo perspective...

BACKGROUND: Hyponatremia has recently been associated with subsequent cancer risk. This population-based nationwide study assessed whether the diagnosis of hyponatremia can predict a cancer diagnosis within most common cancers. MATERIAL AND METHODS: Using Danish medical registries, we identified 16,220 patients with a first-time diagnosis of hyponatremia, without a cancer diagnosis, from January 2006 through November 2013. We quantified the relative risk of a subsequent cancer diagnosis by standardized incidence ratios (SIRs), comparing observed cancer incidence among patients diagnosed with hyponatremia to that expected, based on national cancer incidence during that period...

<p>Seborrheic keratosis (SK) is a benign epidermal keratinocytic tumor that is extremely common, particularly in individuals over the age of 50. Most individuals with SK will have more than one lesion and the presence of over 10 lesions in the same person is not uncommon. Although the clinical morphology of most SK with their stuck-on, symmetric, keratotic, and waxy appearance makes them easy to identify, many manifest a morphology resembling melanoma or squamous cell carcinoma. One can argue that such cases will ultimately not prove to be problematic since a simple biopsy will easily reveal their benign nature and eliminate any concerns...

Certain groups of individuals seem to have an increased risk of committing suicide, and a number of studies have reported an increased risk of suicide among cancer patients. In this study, we aim to estimate the risk of suicide among cancer patients in Lithuania over the period 1993-2012. The records of patients diagnosed with primary cancer were extracted from the population-based Lithuanian Cancer Registry and 273 511 cases of first cancer were included in the analysis. Sex, age and calendar period-standardized mortality ratios (SMRs) were calculated by dividing the observed numbers of suicides among cancer patients by the expected number using national rates...

Cutaneous leiomyosarcoma is an uncommon superficial soft tissue sarcoma and mainly found in the middle aged to elderly males. It can occur in any part of the body, mostly affecting the extremities and rarely affecting the face. It grows relatively slowly, can be diagnosed by biopsy and is treated by surgical excision. It needs to be distinguished from other spindle cell neoplasms, and immunohistochemical markers are usually required to attain an accurate diagnosis. We report a case of cutaneous leiomyosarcoma appeared on the left cheek within 6 month of a 73-year-old female patient suspected with malignant melanoma before surgery...

We describe a case of a giant conjunctival nevus presented in a 12-year-old girl with suspicious clinicomorphological appearance. The lesion was noticed by the parents at the age of 3 years as a "fleshy spot" on the bulbar conjunctiva. The lesion remained unchanged until approx. 6 months before recent admission. On slit-lamp examination, a large conjunctival lesion with variegate pigmentation and indistinct margins was detected on the superonasal part of the bulbar conjunctiva of the left eye. Intralesional cysts and vessels were detected with AS-OCT examination...

Malignant Melanoma (MM) is among the most dangerous malignancies with some of the least known survival rates. Melanoma most commonly metastasizes to regional lymph nodes, the lungs, and brain. Metastatic disease of the gallbladder (GB) is exceptionally rare making it difficult to diagnose. The fact that typically patients do not present until they are symptomatic-only after widespread metastatic disease has already occurred-is further complicating the diagnosis of MM of the GB. For this reason, MM of the GB is rarely discovered in living patients...

Objectives: Accurate diagnosis of malignant peripheral nerve sheath tumor (MPNST) is often challenging on fine-needle aspiration (FNA) or core needle biopsy. Recurrent mutations in EED and SUZ12, which encode subunits of polycomb repressive complex 2 (PRC2), have been identified in 70% to 92% of MPNSTs; PRC2 inactivation leads to loss of trimethylation of lysine 27 of histone H3 (H3K27me3). We evaluated the utility of H3K27me3 immunohistochemistry for distinguishing MPNST from its cytomorphologic mimics...

BACKGROUND: Skin cancer patients are primarily at increased risk of developing subsequent skin cancers of the same type. Shared risk factors might also increase the occurrence of a different type of subsequent skin cancer. OBJECTIVE: To investigate risks of different skin tumor combinations after a first melanoma, squamous cell carcinoma (SCC) and basal cell carcinoma (BCC). METHODS: All melanoma and SCC patients included in the national Netherlands Cancer Registry (NCR) and all BCC patients included in the regional Eindhoven Cancer Registry (ECR) between 1989 and 2009 were followed until diagnosis of a subsequent different skin cancer (melanoma, SCC or BCC), date of death or end of study...

BACKGROUND: Differences in cancer survival exist across socio-economic groups for many cancer types. Standard metrics fail to show the overall impact for patients and the population. METHODS: The available data consist of a population of ∼2.5 million patients and include all patients recorded as being diagnosed with melanoma, prostate, bladder, breast, colon, rectum, lung, ovarian and stomach cancers in England between 1998 and 2013. We estimated the average loss in expectation of life per patient in years and the proportion of life lost for a range of cancer types, separately by deprivation group...

Melanoma accounts for the majority of skin cancer-related deaths, and its incidence continues to rise worldwide. While advanced disease has historically been associated with poor long-term survival, early-stage disease has a favorable prognosis and therefore, early diagnosis is paramount. Resection of primary melanoma requires a balance of maximizing oncological outcome while minimizing morbidity. Wide excision with 1-2 cm margins, depending on depth of the tumor, is the standard of care for surgical treatment of primary, invasive melanoma...

To present current melanoma diagnosis, staging, prognosis, and treatment algorithms and how recent advances in laser pump-probe microscopy will fill in the gaps in our clinical understanding. Expert opinion and significantly cited articles identified in SCOPUS were used in conjunction with a pubmed database search on Melanoma practice guidelines from the last 10 years. Significant advances in melanoma treatment have been made over the last decade. However, proper treatment algorithm and prognostic information per melanoma stage remain controversial...

Subungual melanoma is a rare subtype of cutaneous melanoma that arises from the structures of the nail apparatus. It presents most commonly in older patients and at an advanced stage. A retrospective review of all patients with subungual melanoma in a single institution over a 15-year period was performed. In total, 54 patients were included (26 males, average age 62.9 years), of which 28 cases involved the upper limb. Median tumour thickness was 4.5 mm. Eighteen patients had lymph node metastasis at diagnosis, including 11 of 36 patients with positive sentinel lymph node biopsy...

Early diagnosis and treatment of melanoma improve survival. New technologies are emerging that may augment the diagnosis, assessment, and management of melanoma but penetrance into everyday practice is low. In the current health care climate, greater emphasis will be placed on the incorporation of technology for clinically suspicious pigmented lesions to facilitate better, more cost-effective management.

Most melanocytic tumors can be characterized as a benign nevus or a melanoma by a trained pathologist using traditional histopathological methods. However, a minority demonstrates ambiguous features and continues to be a diagnostic challenge. Genetic expression profiling (GEP) assays have been developed in an effort to resolve this dilemma. These assays measure mRNA levels of specified genes using reverse transcription quantitative polymerase chain reaction technology. The development of GEP assays, methodology, challenges associated with GEP validation and testing, and the suitability of a currently available GEP test for clinical use are reviewed...

The assessment of melanoma by light microscopy with hematoxylin-eosin staining remains an often subjective process. However, there are additional diagnostic measures that may be of utility, such as immunohistochemical staining and genetic evaluation. Adjunctive genetic assessment to augment the diagnosis of melanoma includes comparative genomic hybridization or fluorescent in situ hybridization to assess for gains or losses in genetic material, or gene expression profiling in some form, to ascertain the expression of genes associated with malignancy...

Rossitza Lazova, Erin H Seeley
Mass spectrometry imaging can be successfully used for skin cancer diagnosis, particularly for the diagnosis of challenging melanocytic lesions. This method analyzes proteins within benign and malignant melanocytic tumor cells and, based on their differences, which constitute a unique molecular signature of 5 to 20 proteins, can render a diagnosis of benign nevus versus malignant melanoma. Mass spectrometry imaging may assist in the differentiation between metastases and nevi as well as between proliferative nodules in nevi and melanoma arising in a nevus...

Electrical impedance spectroscopy (EIS) is a noninvasive method that aims to help diagnose skin cancer. The EIS device consists of a handheld probe with a disposable electrode that is applied directly on the skin and uses electrical impendence differences to differentiate between normal and abnormal skin lesions. The EIS algorithm is best used on lesions that are deemed clinically or dermoscopically suspicious and has a high sensitivity in detecting malignant melanoma. The greatest usefulness of EIS is achieved in conjunction with a physician who has experience with this modality and excellent training in the clinical detection of suspicious lesions...

Multispectral analysis devices assess pigmented lesion disorganization at different levels using variable wavelengths of light. Computerized algorithms measure morphologic disorganization of the pigmented skin lesion. Aggregated data of 855 participants investigating the influence of multispectral digital skin lesion analysis (MSDSLA) on practitioner decisions to biopsy pigmented skin lesions revealed the overall sensitivity for detection of melanoma improved from 70% to 88%. Participant specificity increased from 52% to 58% after MSDSLA...
