Comparison of the classification by microscopic level (stage) of malignant melanoma by three independent groups of pathologists

Abstract

The ability of groups of pathologists to classify and stage malignant melanoma varies with their familiarity with the new nomenclature proposed for that process. Primary lesions of malignant melanoma from 79 patients were independently examined and classified by community pathologists, university pathologists, and a referee pathologist all without access to each others diagnoses. The diagnoses of these groups were compared for agreement in variety of melanoma as well as depth of dermal penetration (stage or level). Greatest success (agreement with the referee) of both the community pathologists and the university pathologists was achieved when assessment of level of invasion (+/- 1) of the referee was compared (community pathologists = 94% +/- 12% agreement, university pathologists = 99% +/- 2% agreement). Our survey demonstrates that only a relatively small number of community pathologists (23%) employ the new nomenclature, but they do so with a facility equal to that of the university pathologists. Based upon this study and our continuing experiences, we recommend the review of all primary lesions of malignant melanoma by a pathologist or group experienced in the diagnosis and microscopic staging of the disease.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Alzheimer's Disease: MS4A

Variants within the membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease in genome-wide association studies. Here is the latest research on Alzheimer's disease and MS4A.

Pediculosis pubis

Pediculosis pubis is a disease caused by a parasitic insect known as Pthirus pubis, which infests human pubic hair, as well as other areas with hair including eye lashes. Here is the latest research.
