Plantar warts are warts that develop on plantar surfaces -- that is, the soles (or bottom) of the feet. Normal standing and walking tends to force them into the skin, and the pressure makes the feet very painful.
Iododerma and bromoderma. Iodides and bromides are drugs that can cause severe adverse cutaneous reactions, and of these, the worst are acneiform, furuncular, carbuncular, chancriform, pyodermatous, or granulomatous. Iodides and bromides are widely distributed, not only in foods and in the environment but also in proprietary and formally prescribed medicaments. These figures are of still relatively minor consequences of adverse reactions from the two halides, of which bromides are usually worse than iodides. Lesions like those of acne or folliculitis caused by an iodide are shown.
Phytophotodermatitis. In addition to perfumes, a number of plants, grasses, fruits, and vegetables contain psoralen as a photosensitizer. The child who helps mother or father slice limes before a trip to the park may develop an identical eruption on the hands. Celery and parsley may present similar problems. It is important to recognize this entity since some affected infants and children have been mistakenly thought to have bruising from child abuse.
