Mild forms of dark spots (hyperpigmentation) on the skin are not usually medically significant. Sunspots on the hands of a middle-aged, fair-skinned woman, for example, may be a cosmetic concern to her, but they are typically benign and in no way endanger her health. However, if these spots were to grow or get darker in a dramatic fashion, it would be best to consult a dermatologist to discern if they are in fact harmless or not.
As summer tans fade, we may see remnants on our skin of those happy hours spent in the sun. That is because the cells (melanocytes) that produce skin tone or pigment (melanin) are stimulated by sun exposure to produce more melanin. Excess melanin can cause visibly uneven areas of darker skin, a condition called hyperpigmentation. Conversely, other areas may lose melanin, resulting in pale or white spots, a condition called hypopigmentation.
This morning I was doing my usual morning scan of CNN for interesting stories and found that they published a Q&A for "What can I eat to keep my skin looking younger?" Below you will find an article written by Dr. Andrea Pennington that was originally posted on Skinsight on October 19, 2009 (link to original post and some great related topics are below). - Jeremy, VisualDx Staff Is Your Diet Aging You? I can tell what my 3-year-old daughter has been snacking on because it’s visible all over her precious face. Would you be surprised to learn that the telltale signs of what you have been eating – or avoiding – are equally noticeable just by looking at your face? It’s true. Dermatologists explain that our skin is a window into our overall health and can show clues of what’s going on under the surface.

Diagnosis Synopsis Cocaine Levamisole Toxicity : Cocaine contaminated with levamisole has been detected in the United States since 2003, and the incidence of toxicity caused by this contamination has been increasing rapidly since 2008. Use of cocaine that has been adulterated with levamisole can lead to a constellation of symptoms including agranulocytosis, neutropenia, and a vasculitis-like purpuric tender skin eruption. The most common sites of purpura are the external ears and cheeks. The purpura is generally followed by skin necrosis, but resolves several weeks after cessation of cocaine use. Recurrent use of contaminated cocaine generally results in recurrent skin eruptions.
Measles has been on the rise in the US. This is due, in part, to concerns regarding the safety of the MMR vaccine. Although recent research has provided strong evidence against the association of autism with MMR vaccine administration, some parents still choose to request one or more vaccine exemptions on the basis of personal beliefs for their child to attend day care or school.
November is healthy skin month. This is a good reminder that, even though we’re exposed to less sun now, it is still a great time to protect the appearance of and marvel at the uniqueness of our body’s largest organ. I’ve always admired the visual beauty of different skin tones. But understanding the science and purpose behind the various shades of our human tapestry expands my appreciation even more. This month, in a blog called Skin Tones, I share some insights on why we all have ”skin of color.”
With infestations on the rise recently, bedbugs have been quite popular in the news. Bedbug bites are extremely uncomfortable and lead to itchy skin reactions similar to other insect bites, such as mosquito bites. Their notoriety comes both from increasing numbers of hotels, apartments, and retail stores with large infestations and from the difficulty of eradicating these pests.
