Medical Reference Related to Skin Problems & Treatments

  1. Furuncle: S. Aureus

    Furuncle: S. aureus. Soft-tissue swelling of the forehead with central abscess formation, nearing rupture.

  2. Erythema Nodosum

    Erythema nodosum. Red, tender, subcutaneous nodules on the extensor aspects of the legs between knees and ankles are a common condition of many causes, some clear, some likely, and many obscure. The most important conditions that are heralded or attended by erythema nodosum are such infections as streptococcal upper-respiratory infections, ulcerative colitis, histoplasmosis, coccidioidomycosis, tuberculosis, syphilis, and leprosy. Another condition that is sometimes revealed by investigation of erythema nodosum is sarcoidosis. Drugs, including oral contraceptives, appear to be the cause of particular cases of erythema nodosum. In many cases, however, no clear cause can be found.

  3. Port-Wine Stain after Laser Treatment

    Marked resolution of the port-wine stain after multiple treatments with pulsed dye laser.

  4. Keloid

    Keloid. Spontaneous keloids on the chest of an adolescent.

  5. Hand Foot Mouth Disease in Mouth

    Hand-foot-mouth disease. This common and benign viral disease of childhood is usually caused by the A16 strain of coxsackievirus, although other strains of the same virus have been implicated. It most often occurs in late summer and early fall. The prodrome consists of low-grade fever and malaise. Shortly thereafter, vesicular lesions arise on the soft palate, tongue, buccal mucosa, and uvula. The lips are usually spared. Occasionally, these lesions may be painful and cause some difficulty in eating. The cutaneous lesions develop 1 or 2 days after those in the mouth. They consist of asymptomatic round or oval vesiculopustules that evolve into superficial erosions. The edges of the palms and soles are a favored location.

  6. Clubbed Nails

    Clubbed nails. Increased curvature of the nail plate may be due to a wide variety of causes. In this patient, the large, convex nails are a hereditary anomaly and were found to be present in both father and brother. Other causes of clubbing of the nails in children include cyanotic congenital heart disease, cystic fibrosis, and chronic inflammatory bowel disease.

  7. Dysplastic Nevi (Atypical Moles) Close-Up

    Dysplastic nevi are moles that are larger than average (larger than a pencil eraser) and irregular in shape. They tend to have uneven color with dark brown centers and lighter, uneven edges.

  8. Head Lice

    Lice are tiny insects that live on humans and feed on blood. When a large number of lice live and multiply on a person, it is called an infestation.

  9. Varicella-Zoster Virus Infection

    Varicella-zoster virus infection: varicella. Multiple, very pruritic, erythematous papules, vesicles (“dewdrops on a rose petal”), and crusted papules on erythematous, edematous bases on the face and neck of a young female. The spectrum of lesions, arising over 7 to 10 days, is typical of varicella.

  10. Signs and Symptoms of Bedbug Bites

    The first sign of bedbugs may be red, itchy bites on the skin, usually on the arms or shoulders. Bedbugs tend to leave straight rows of bites, unlike some other insects that leave bites here and there.
