ReviewCutaneous photosensitivity diseases induced by exogenous agents.
Cutaneous photosensitivity diseases may be idiopathic, produced by endogenous photosensitizers, or associated with exogenous photosensitizers. Those caused by exogenous agents include phototoxicity, photoallergy, and the exacerbation or induction of systemic disorders in which photosensitivity is a prominent clinical manifestation. Phototoxic disorders have a high incidence, whereas photoallergic reactions are much less frequent. ⋯ Drugs capable of causing phototoxic reactions include psoralens, porphyrins, coal tar, antibiotics, and nonsteroidal antiinflammatory agents. Drugs capable of causing photoallergic reactions include topical antimicrobial agents, fragrances, sunscreens, nonsteroidal antiinflammatory agents, plants, and psychiatric medications. Drug-induced systemic diseases in which photosensitivity is a prominent component include drug-induced lupus erythematosus, porphyria, and pellagra.

Symmetric areas of erythema and induration developed on the cheeks of a 17-day-old black girl after ice packs were applied to her face for treatment of supraventricular tachycardia. To our knowledge, this is the first report of cold panniculitis caused by treatment of a cardiac arrhythmia with ice packs.

Case ReportsTreatment of cutaneous and pulmonary sarcoidosis with thalidomide.
Many therapeutic agents have been proposed for treatment of steroid-resistant sarcoidosis. Because administration of low doses of thalidomide has been successful in treating other inflammatory diseases, it was used in a patient with systemic sarcoidosis who was unresponsive to corticosteroids and in a patient with pulmonary sarcoidosis, in whom Kaposi's sarcoma developed after a course of corticosteroid therapy. Thalidomide, 200 mg/day for 2 weeks followed by 100 mg/day for 11 weeks, was given. ⋯ No relapse has occurred. Thalidomide, particularly because of its inhibition of the macrophage function, may be a useful alternative therapy in steroid-resistant cases. In addition, the correlation between the angiotensin-converting enzyme level and the clinical improvement observed in our patients suggests a direct parallel between angiotensin-converting enzyme and the activity of the granulomatous process.
