1. Tinea pedis is also known as “athlete’s foot.” What is the most common presentation of athlete’s foot? According to the CDC, athlete's foot is typically characterized by skin fissures or scales that can be red and itchy. Additionally, tinea pedis is a common dermatophyte infection and can present with many different signs and symptoms. It may present in classic ringworm pattern, involve interdigitally, and in the soles of the foot. 1. Interdigital - Erythema and scaling between the 4th and 5th toes, although any digit can be affected. 2. Mocassin type - Affects entire sole and chronic silvery white scale may also occur in the palms of the hand. The creases of the palms and the soles are thickened and the creases are white. 3. Vesicular-type - Appears on the sole or top of the foot. Blisters may involve remote site. 2. Describe the etiology of lymphedema. The swelling that results from lymphedema is nonpitting. It may be primarily due to congenital or inherited conditions, or secondary caused by damage to the lymphatic system, cancers (usually breast, ovarian, and prostate), infection, inflammation, or obesity. Chronic lymphedema is commonly due to surgery, radiation, or infection that damages the lymphatic system. 3. Cellulitis is most commonly caused by which pathogens? Cellulitis is commonly caused by groups A, B, C, and G beta-hemolytic streptococci, Staphylococcus aureus [both methicillin susceptible (MSSA) and methicillin resistant (MRSA)], and occasionally a gram-negative organism. It can also be caused by human or animal bite pathogens. 4. Your 78-year-old patient comes in yearly for a skin check. She was a self-proclaimed “sun worshipper” in her younger days. She has multiple freckles over her face, arms, and back. She is concerned about a freckle on her back that seems to be getter larger. This is what you see, what is your impression? The patient's lesion appears to me as a melanoma. This fits the description of melanoma which is a flat to slightly raised pigmented lesions with irregular borders. Melanoma is a type of skin cancer and the incidence of all skin cancers increase with age, degree, and intensity of sun exposure. This patient is 78 years old and reported she was a "sun worshipper" so there has been a lot of exposure to the sun in her younger days that puts her at risk to developing melanoma. The picture also shows a nevi and some literature has shown that the presence of multiple and atypical nevi are contributing factors to developing melanoma.
