This week we have another learning opportunity with a real-life scenario from Dr Colin Armstrong. This elderly lady had recently had a melanoma excised (you can see the scar). At a routine skin check, the below pigmented lesion was observed.
What is your evaluation and next steps (if any)?
This week we have an interesting case from Dr Tim Aung. A mid 60’s male was found with a suspicious pigmented lesion over his left mid-back during a consultation for other health problem.
Have a look at the images here and provide your evaluation and next steps (if any).
Because the incidence of cutaneous malignant melanoma (CMM) was reported to increase with increasing terrestrial UVR (290–400 nm) doses in the US back in 1975 and a recent publication showed no association exists with UVR exposure at all, we set out to fully elucidate the role of UVR in CMM. To achieve this goal, we analyzed the CMM incidences over latitude and estimated the average personal UVR dose in the US and numerous countries (> 50) on 5 continents around the world. Using data from the International Agency for Research on Cancer in 2005, we performed worldwide analysis of CMM over UVR dose by sex, age group (0–14, 15–29, 30–49, 50–69, 70–85+) and Fitzpatrick skin types I-VI. Surprisingly, increasing UVR doses, which represent erythemally-weighted doses comprised primarily of UVB (290–315 nm) radiation, did not significantly correlate with increasing CMM incidence for people with any skin type anywhere in the world. Paradoxically, we found significant correlations between increasing CMM and decreasing UVB dose in Europeans with skin types I-IV.
In this short video, Associate Professor Giuseppe Argenziano presents the new AJCC classification of melanoma which has just been released. There are two main changes as compared to the 2009 version which are important for your skin cancer practice.
Public health authorities in the United States are recommending that men, women and children reduce their exposure to sunlight, based on concerns that this exposure will promote skin cancer. On the other hand, data show that increasing numbers of Americans suffer from vitamin D deficiencies and serious health problems caused by insufficient sun exposure.
This week we have a case submission from Dr Tim Aung. An 89-year-old male with a history of melanoma presents for a regular skin check. During the skin examination the doctor noted a lesion on the mid-upper chest of his patient.
What is your evaluation, clinically and dermoscopically? What are your next steps?
In this short video skin cancer expert Giuseppe Argenziano presents a fascinating case of a patient with metastatic melanoma who refused all treatment. After a few years, the patient is still alive as her immune system was able to control the disease which will usually lead to death within a short period of time.
An 54-Year-old patient presented for a skin check with concern about this mole on his anterior chest.
Please describe what you see from the clinical and dermoscopy images. Is it Seb k or Melanoma? and Why?
Our research article this month is a follow-on from the one we posted recently, about having skin checks done by “intimate partners”. In this new analysis, June Robinson and colleagues looked at whether embarrassment among dyads (that is, pairs) was a barrier to having a skin check done by a partner, and whether confidence in ability to identify suspicious lesions could be enhanced.

The barriers to sunscreen adherence that are typically cited include cost, cosmesis, forgetfulness, societal influences, and confusing messages about efficacy and safety. Without doubt, the aesthetic or cosmetic properties of sunscreen, such as texture and feel, also contribute to sub-optimal use.
