The 2008 evidence-based clinical practice guidelines for the management of melanoma are currently being revised and updated in a staged process by a multidisciplinary working party established by Cancer Council Australia. The guidelines for definitive excision margins for primary melanomas have been revised as part of this process. Continue reading “Updated Practice Guidelines for Melanoma Management”
Complete removal of individual dysplastic nevi is often achieved by a second surgical procedure after the initial biopsy. The choice to perform the second procedure is strongly influenced by the histopathologic margins of the initial biopsy specimen.
A study recently published in the Journal of the American Academy of Dermatology evaluated the clinical and histopathologic outcomes of total biopsy of dysplastic nevi using a pre-determined margin of normal skin. Continue reading “Biopsy Margin for Total Removal of Dysplastic Nevi”
This week we have an engaging case from Dr Tim Aung. A 40-year-old female with concerns about a lesion presented for months.
Please review and describe the clinical and dermoscopic images. What is your evaluation, and differential diagnosis? What would you do? Continue reading “Case discussion: How would you treat this patient? [15 January]”
How does suturing technique affect cosmetic outcomes after facial surgery? Recent research published in the Journal of the American Academy of Dermatology sought to compare the cosmetic results of simple interrupted sutures versus running subcuticular sutures in facial surgery.
In a controlled trial, adults receiving dermatologic surgery on the face (for conditions such as skin cancer) were randomised to receive either simple interrupted sutures (73 patients) or running subcuticular sutures (69 patients). Continue reading “Suturing Technique for Best Cosmetic Outcomes”
A surgical margin of at least two millimetres around a cancerous skin lesion is the minimum requirement to ensure total removal of cancer cells and to avoid the need for further surgeries, according to a study by researchers at Perlmutter Cancer Center at NYU Langone Health.
The results of a study enlisting 138 skin cancer patients was published in the Journal of the American Academy of Dermatology, and found that excising a two millimetre margin beyond the edges of a suspicious mole was best practice for complete removal.
In this short video, experienced skin cancer doctor Colin Armstrong demonstrates how to use steri-strips for wound closures on thin skin, particularly on elderly patients. Continue reading “How to Close Wounds on Paper Thin Skin”
In this skin cancer update video, Associate Professor Giuseppe Argenziano discusses the revolutionary results of a study comparing lymph-node dissection with observation in patients with advanced metastatic melanoma. Of patients who had a positive sentinel-node biopsy, the study compared the outcomes of patients who underwent complete lymph-node dissection with the outcomes of patients who were just observed after a positive sentinel-node biopsy and did not undergo a dissection.
This week we have another great case from Dr Slavko Doslo. An older female presented for a skin check and there was an obvious standout lesion on her face.
We have the clinical and dermoscopy picture below. What do you think about the lesion? What are the next steps you would take to treat this patient? Continue reading “Case discussion: How would you treat this patient? [02 October]”
Skin cancer doctors and dermatologists may be tempted to over-treat patients with minor skin cancers in order to make a financial profit for performing higher-cost procedures, according to a symposium focusing on controversies in dermatology.
A presentation entitled “Inconvenient Truths in Skin Cancer Care” was delivered at the 26th European Academy of Dermatology and Venereology Congress by Dr Tamar Nijsten from Erasmus Medical Center in the Netherlands. The presentation highlighted concerns that dermatologists and skin physicians and might perform unnecessary treatments on minor skin cancers such as basal cell carcinoma, or prescribe high-cost drugs offering no advantage over generic-brand counterparts, because these approaches financially benefit the physicians.
This week we have an interesting case from Dr Colin Armstrong. An elderly lady presented for a skin check and had a suspicious lesion on calf muscle as shown.
We have the clinical and dermoscopy picture below. What do you think about the lesion? What are the next steps you would take to treat this patient?
