It is usually associated with an acneiform component (papules, pustules, and oily skin). It usually occurs in middle-aged and older people. The cheeks, nose, and chin, on the entire face, may have a rosy hue. Burning or stinging often accompanies episodes of flushing. It is much more common than lupus erythematosus, with which it is often confused. Rosacea is distinguished from acne by age, the presence of the vascular component, and the absence of comedones. Folliculitis Folliculitis is characterized by red-ringed papules and pustules at hair follicles. Gram­ negative folliculitis may be spread by contaminated hot tubs. Gram stain and culture will help to differentiate bacterial from non­ bacterial folliculitis. History is important for pinpointing the cause of non-bacterial folliculitis. Impetigo Superficial honey-colored serous crusts are characteristic of this disorder. It is usually caused by a staphylococcus infection. Culture is rarely reliable. Seborrheic Keratoses These lesions are benign overgrowths of epithelium, largely appearing on the torso, face, and neck. They are seen on almost every­ one over the age of 50. The borders are typically irregular, and they range in color from beige or gray-white to very dark brown. These "barnacles" of older skin can number only a few to as many as hundreds. Although often raised and dry, they can be flatter and greasier (seborrheic) in texture. Granuloma Pyogenicum This is a vascular reactive nodule that develops as a response to a minor injury. The overgrowth of capillaries leads to a raised red lump which bleeds profusely when torn. Lentigo Simplex These lesions occur on sun-exposed skin, especially face, arms, and hands. Lesions are flat, and pigmented in shades of brown, with characteristically sharp borders. They tend to fade with sun avoidance. Varicella Chicken Pox The rash is pruritic and most prominent on the face, scalp and trunk. It appears as multitudes of red­ ringed papules and vesicles in varying stages of development. Crusts eventually form and slough off in 7 to 14 days. Nondermatomal distribution and lesions of varying stages distinguish primary varicella from herpes zoster. Fever and malaise may be mild in children and much more severe in adults.
