The presence of atypical vessels (p = 0.02) and shiny white structures (p = 0.02) were significantly associated with invasive melanoma.Įvaluation for certain evolving dermoscopic features in melanocytic lesions monitored by SDDI and TBP is efficient in assisting clinical decision making. Features most strongly associated with melanoma included the development of neovascularisation, asymmetry and growth in pigment network, additional colours, shiny white structures, regression, structureless areas and change to a multi-component pattern. Histopathologically confirmed melanoma and benign naevi that underwent SDDI and TBP with a minimum follow-up interval of 3 months were included.Įighty-nine melanomas (38.2% invasive, median Breslow thickness 0.35 mm, range: 0.2-1.45 mm) and 48 benign naevi were evaluated by three experienced dermatologists for dermoscopic changes. Histopathology reports from a private specialist dermatology clinic from January 2007 to December 2019 were reviewed. This study aims to identify and compare dermoscopic features in developing melanomas and benign naevi that underwent SDDI and TBP to understand which dermoscopic features may be associated with a malignant change.
#Sequential photography serial
Dermoscopic features specific to melanoma have been well described, however, dynamic changes on serial imaging are less understood.
When I find the link I will post it.Sequential digital dermoscopic imaging (SDDI) and total body photography (TBP) are recommended as a two-step surveillance method for individuals at high-risk of developing cutaneous melanoma. It was shot sometime in the 60's and the barge company bought the images to use in safety class. There are about 4-6 frames of the whole incident. The pictures are shot by someone who was just there and happened to have a camera. The only thing that saved the pilot and engineer (deckhands went with the load) was the fact that the engine room doors were shut tight and they had poured concrete as ballast in the engine room, otherwise the boat would have filled up and gone down quickly. When the boat got to the other side it popped right side up and you could see water flowing out of the pilot house. The boat swung sideways and hit the bridge, then the current took the boat under water. The story was that the barge pilot was going to let his cargo flow down the river under the bridge and pick it up on the other side because he was too tall to get under with the water so high, but the current wouldn't let him reverse or turn around, so under the bridge he went. It was on the Kentucky river I believe and at high water. I saw on the web one place, I am still trying to find the link but haven't yet, of a barge pulled under a bridge and capsizing only to come out on the other side and right itself. Unfortunately I forgot to consider including some time atthe end to also capture allīut the very beginning of the spread of the dust cloud, which would have made aĭramatic coda to the sequence as the people who ignored safety warnings startedīut the details in sequence I did get are great, the clear light of morning was perfectĪnd in the film you can clearly see individual bricks flying away from the facade oftheīuilding and in somecases the flash of indiviual explosions.
