BACKGROUND:  Melanoma incidence has increased in recent decades in the United States. Uncertainty remains regarding how much of this increase is attributable to greater melanoma screening activities, potential detection bias and overdiagnosis. OBJECTIVE: Use a cross-sectional ecological analysis to evaluate the relationship between skin biopsy and melanoma incidence rates over a more recent time period than prior reports. METHODS: Examination of the association of biopsy rates and melanoma incidence (invasive and in situ) in SEER-Medicare data (including 10 states) for 2002-2009...

IMPORTANCE: Basal and squamous cell carcinoma are the most common types of cancer in the United States and represent the vast majority of all cases of skin cancer; however, they rarely result in death or substantial morbidity, whereas melanoma skin cancer has notably higher mortality rates. In 2016, an estimated 76,400 US men and women will develop melanoma and 10,100 will die from the disease. OBJECTIVE: To update the 2009 US Preventive Services Task Force (USPSTF) recommendation on screening for skin cancer...

AIM OF STUDY: Incidence rates of melanoma, generated by cancer registries (CRs), are susceptible to reporting inconsistencies due to increasing decentralisation of diagnosis. We therefore independently assessed the burden of melanoma in Austria. METHODS: We collected histopathological reports on melanoma of all patients diagnosed in Austria in 2011. Demographic and clinical characteristics, histopathological tumour stages were assessed. Their regional distributions and incidence rates were analysed and compared with data of national and international CRs...

BACKGROUND: A disproportional increase in in situ or thin melanomas may point at underlying causes such as increased melanoma awareness, as well as 'overdiagnosis' of melanoma in diagnostically equivocal small lesions. OBJECTIVES: The purposes of this study were to estimate trends in melanoma incidence by sex, Breslow thickness (thin melanomas subdivided into four subgroups: <0.25 mm, 0.25-0.49 mm, 0.50-0.74 mm, and 0.75-1.0 mm), age and location, and to compare these with trends in subgroups of thicker melanomas...

BACKGROUND: In Europe skin melanoma (SM) survival has increased over time. The aims were to evaluate recent trends and differences between countries and regions of Europe. METHODS: Relative survival (RS) estimates and geographical comparisons were based on 241,485 patients aged 15years and over with a diagnosis of invasive SM in Europe (2000-2007). Survival time trends during 1999-2007 were estimated using the period approach, for 213,101 patients. Age, gender, sub-sites and morphology subgroups were considered...

Jérôme Viguier
The past 20 years have seen major advances in screening for different cancer types. Screening is however destined to evolve, in terms of target populations, procedures used and the overall positioning of screening in the fight against the different forms of cancer. At the same time, screening is expected progressively to become more closely tailored to the level of risk; the type of tests and the frequency with which they are used will be adjusted in a more personalized approach. A critical issue is also to provide the population at large with more extensive information on the advantages and disadvantages, particularly of screening programmes known for the potentially high rate of overdiagnosis...

OBJECTIVE: To determine the optimal method for quantifying and monitoring overdiagnosis in cancer screening over time. DESIGN: Systematic review of primary research studies of any design that quantified overdiagnosis from screening for nine types of cancer. We used explicit criteria to critically appraise individual studies and assess strength of the body of evidence for each study design (double blinded review), and assessed the potential for each study design to accurately quantify and monitor overdiagnosis over time...

BACKGROUND: It is often assumed that increases in cancer survival reflect true progress against cancer. This is true when these increases are accompanied by decreased burden of disease: Fewer people being diagnosed or dying from cancer (ie, decreased incidence and mortality). But increased survival can also occur even when incidence is increasing and mortality is unchanged. OBJECTIVE: To use trends in cancer burden-incidence and mortality-to illustrate when changes in survival reflect true progress...

AIMS: Melanocytic naevi on the umbilicus have been described as a form of flexural naevi, with the most common feature being a 'nested and dyshesive pattern'. We have encountered a distinct group of umbilical naevi with more significant atypia and prominent fibrosis, not reported previously. This study aimed to characterize these naevi more clearly. METHODS AND RESULTS: Eighty-one umbilical naevi from 2000 to 2013 were reviewed retrospectively, 20 cases of which showed lamellar fibrosis and atypia and were designated as atypical umbilical naevi (AUN)...

Angiomatoid fibrous histiocytoma is an uncommon soft-tissue tumor of intermediate malignancy that is often misdiagnosed initially. As there is not one immunohistochemical marker that consequently stains positive or negative for angiomatoid fibrous histiocytoma, molecular diagnostics are becoming more widely used. So far three translocations have been reported to arise in angiomatoid fibrous histiocytoma: FUS-ATF1, EWSR1-CREB1, or EWSR1-ATF1. We present a case of angiomatoid fibrous histiocytoma on the upper arm of a 40-year-old female, which was initially misdiagnosed as metastatic melanoma in a lymph node...

The incidence of cutaneous malignant melanoma is continuously increasing worldwide, but only minimal changes in mortality have been observed. This phenomenon has brought into question whether this increased incidence reflects a true or apparent melanoma epidemic. The most recent data suggest that this epidemiological trend may be explained by the existence of a certain degree of melanoma overdiagnosis, especially of thin lesions, which probably would never progress to advanced disease if left untreated. However, acute sun exposure and widespread use of sunbeds may also justify the increase in melanoma incidence...

BACKGROUND: Transepidermal melanocytic migration (TEM) is an important diagnostic criterion for malignancy, especially in association with cytologic atypia. However, TEM may also be observed in benign melanocytic tumors, such as Spitz nevus, acral nevi, or nevi in infancy. We discuss the value of TEM for the diagnosis of melanocytic tumors in a young patient previously diagnosed as having 11 cutaneous melanomas. OBSERVATION: A 17-year-old patient with a history of 11 cutaneous melanomas diagnosed in the past 3 years by different expert dermatopathologists presented in our department...

The rise in malignant melanoma incidence has been termed "epidemic". Closer scrutiny of epidemiologic data suggests overdiagnosis as the true cause of the dramatic rise in melanoma incidence. In epidemiologic terms, "overdiagnosis" describes lesions that are histologically malignant but biologically benign. Overdiagnosis is not unique to melanoma screening but is prevalent in screening for cancers of other organs, including the thyroid and prostate glands.

Wolfgang Weyers
In the past decades, the incidence of melanoma has been reported to rise in epidemic proportions. The chief reason for that pseudo-epidemic is improved criteria for diagnosis that allow melanomas to be recognized far more accurately and at earlier stages. The rising number of melanomas diagnosed has resulted in increased diagnostic scrutiny, more pigmented lesions being biopsied and more melanomas recognized, thus enhancing the 'epidemic' in self-perpetuating fashion. Regression of melanomas may, in part, explain why lesions undetected before did not result in a far higher mortality...

The pathology of melanocytic tumours remains one of the most challenging and controversial fields in diagnostic histopathology, and it is one of the leading causes for litigation against pathologists. This is due largely to the wide morphological spectrum and often only subtle differentiating features with potential for both under- as well as overdiagnosis of melanoma. Particular pitfalls include the diagnosis of rare and unusual melanoma variants and melanoma resembling naevi. Furthermore, a subset of benign naevi may show concerning features associated more typically with a diagnosis of melanoma...

The increased incidence of cutaneous malignant melanoma, together with only minor changes in mortality, has brought into question the existence of a melanoma epidemic. The discrepancy between incidence and mortality suggests that most newly diagnosed melanomas have indolent behaviour. This review summarizes the most recent epidemiological findings regarding the incidence of cutaneous malignant melanoma, mortality, Breslow thickness and clinical stage. Studies published between 2005 and 2010 with more than 2,000 test subjects were included in this review...

Nevi with site-related histological atypia have been reported in various locations, mainly on the female genitalia, along the anatomical milk line and in skin folds. Therefore, the literature focuses clearly on the atypical nevi of the female genitalia. In the present case, we describe a unique case of a combined perianal melanocytic nevus with architectural and cytologic atypia that differ from the histopathologic features of accepted criteria for atypical genital nevi. A suspicion of malignant melanoma was raised, but few pivotal histological features, the age of the patient and the clinical follow-up for 10 years proved otherwise...

BACKGROUND: There are limited data regarding melanocyte density and distribution on sun-exposed skin of the head and neck, in particular, comparing morphology (hematoxylin-eosin [H&E] staining) and immunohistochemistry (Melan-A staining) on formalin-fixed tissue. Furthermore, comparisons of melanocyte density between distinct geographic populations have not been made using these methods. This information would be useful for physicians who use histologic criteria to diagnose and treat lentigo maligna...

BACKGROUND: It has been debated that the epidemic of melanoma is largely due to overdiagnosis, since increases in incidence were mainly among thin melanomas and mortality rates remained stable. Our objective was to examine this controversy in The Netherlands. PATIENTS AND METHODS: Information on newly diagnosed melanoma patients was obtained from The Netherlands Cancer Registry. European Standardized Rates and estimated annual percentage change were calculated for the period 1989-2008...
