Presents a case study of an aged man who developed basal cell carcinoma. Medical history of the patient; Clinical presentation of the condition; Information on basal cell carcinoma.

Pattern recognition remains a valuable tool in the accurate diagnosis of dermatologic disease. A comprehensive patient history and physical examination denote cornerstones of medical evaluation, and in our specialty, dermoscopy can supplement data gathering to allocate cutaneous eruptions into appropriate categories. We present a case of acute onset palmar discoloration occurring in an otherwise healthy patient. Correct diagnosis transpired in the clinical setting with tailored questioning based on careful examination and adjunct dermatoscopic evaluation.

Background: Psychogenic excoriation describes patients who excoriate without apparent primary skin abnormality., Objective: This study compares the psychiatric profile of patients with psychogenic excoriation with a control group., Methods: Fifty consecutive patients with psychogenic excoriation were matched with 50 control patients and given a questionnaire related to psychiatric history., Results: Study and control groups differed significantly in relation to psychiatric comorbidity, use of psychotropic drugs, history of depression, and history of bipolar disorder. Psychogenic excoriation was not associated with personal history of other psychiatric disorders or family history of psychiatric comorbidity, except alcoholism., Limitations: Nonpsychiatrists may have made the psychiatric diagnoses., Conclusion: Psychogenic excoriation is significantly associated with psychiatric comorbidity, especially depression and bipolar disorder. Awareness by the patient of a link between the psychiatric disorder and the cutaneous condition may help patients in dealing with the distress caused by the unknown nature of the excoriating behavior.

As more individuals choose to maintain their fitness level year-round, they inevitably encounter skin problems. During these athletic pursuits, the skin must endure ongoing insult, serving as the interface between the athlete and environmental factors unique to the sport and season. Therefore, primary care physicians and dermatologists must understand how athletic activity and weather contribute to the development of dermatoses. By appropriately recognizing winter sport dermatoses, the practitioner can best provide tailored effective treatment that enables the patient to quickly return to the winter sport.

Methicillin-resistant Staphylococcus aureus infections have become an increasingly common condition among athletes. Physical contact, shared facilities and equipment, and hygienic practices of athletes all contribute to methicillin-resistant S. aureus transmission among sports participants. This review elucidates the risk factors predisposing to methicillin-resistant S. aureus infection in athletes and provides guidance for treatment and prevention.

Athletes face numerous hazards in their daily activities. An athlete's skin, in particular, endures repeated exposure to trauma, heat, moisture, and numerous allergens and chemicals. These factors combine with other unique and less well-defined genetically predisposing factors in the athlete's skin to cause both allergic contact dermatitis (ACD) and irritant contact dermatitis (ICD). As with other cases of contact dermatitis, these eruptions in athletes present as a spectrum of acute to subacute to chronic dermatitis. Recognizing the unique environmental irritants and allergens encountered by athletes is paramount to facilitate appropriate therapy and prevention. This review comprehensively examines the literature on contact dermatitis in athletes. The different types of contact dermatitis have been classified under sport-specific subheadings. Furthermore, within each subheading, both ACD and ICD types are discussed.

As the United States comes increasingly closer to being the heaviest nation on earth, many people are turning to exercise, especially running, to lose weight. Most runners, whether novice or professional, will have a skin disorder that may prompt them to seek medical attention. Although case reports and sports reviews have discussed, in a cursory fashion, the nature of these skin lesions, to our knowledge there has never been an extensive review of the literature that specifically addresses the skin diseases of runners. In this article, we present the epidemiology, origin, clinical characteristics, treatment, and prevention of skin diseases inherent to runners.

We report an exhaustive review of the hair and nail conditions related to participation in sports. It is important that medical professionals who care for athletes recognize the unique dermatologic conditions that may affect those athletes.

Sports participation may result in myriad cutaneous manifestations, from mundane findings to life-threatening illnesses. Skin infections are among the most common dermatologic ailments in athletes; herpes simplex is clearly among the most serious for the individual athlete, and ultimately the team. Herpes simplex infection most often involves athletes with extensive skin to skin contact. For a variety of reasons, wrestlers and rugby players seem particularly prone. The keys to thwarting epidemics and reducing an athlete's disqualification period include early diagnosis, rapid institution of therapy, and routine systematic preventative measures. This clinical review examines the classification, epidemiology, diagnosis, treatment, and prevention of herpes simplex virus infection as it relates to contact sports. Attention to evidence-based medicine is paid to treatment and prevention techniques. Practical implications for all concerned parties, including athletes, parents, coaches, trainers, and physicians, are discussed.

The most common injuries afflicting the athlete affect the skin. The list of sports-related dermatoses is vast and includes infections, inflammatory conditions, traumatic entities, environmental encounters, and neoplasms. It is critical that the sports physician recognises common and uncommon skin disorders of the athlete. Knowledge of the treatment and prevention of various sports-related dermatoses results in prompt and appropriate care of the athlete. Infections probably cause the most disruption to individual and team activities. Herpes gladiatorum, tinea corporis gladiatorum, impetigo, and furunculosis are sometimes found in epidemic proportions in athletes. Vigilant surveillance and early treatment help teams avoid these epidemics. Fortunately, several recent studies suggest that pharmacotherapeutic prevention may be effective for some of these sports-related infections. Inflammatory cutaneous conditions may be banal or potentially life threatening as in the case of exercise-induced anaphylaxis. Athletes who develop exercise-induced anaphylaxis may prevent outbreaks by avoiding food before exercise and extreme temperatures while they exercise. Almost all sports enthusiasts are at risk of developing traumatic entities such as nail dystrophies, calluses and blisters. Other more unusual traumatic skin conditions, such as talon noire, jogger's nipples and mogul's palm, occur in specific sports. Several techniques and special clothing exist to help prevent traumatic skin conditions in athletes. Almost all athletes, to some degree, interact with the environment. Winter sport athletes may develop frostbite and swimmers in both fresh and saltwater may develop swimmer's itch or seabather's eruption, respectively. Swimmers with fair skin and light hair may also present with unusual green hair that results from the deposition of copper within the hair. Finally, athletes are at risk of developing both benign and malignant neoplasms. Hockey players, surfers, boxers and football players can develop athlete's nodules. Outdoor sports enthusiasts are at greater risk of developing melanoma and non-melanoma skin cancer. Athletes spend a great deal of time outdoors, typically during peak hours of ultraviolet exposure. The frequent use of sunscreens and protective clothing will decrease the athlete's sun exposure. It is critical that the sports physician recognises common and uncommon skin disorders of the athlete. Knowledge of the treatment and prevention of various sports-related dermatoses results in prompt and appropriate care of the athlete.

Topical steroids play an extremely important role in the treatment of various dermatologic conditions. Use of topical steroids must be approached with caution, however, as they can have serious side effects. We report a case of iatrogenic perianal ulcers caused by twice-daily application of Lotrisone (clotrimazole and betamethasone dipropionate) in the perianal region. High-potency topical steroids should be used sparingly and briefly in intertriginous areas.
