We report a case of Grzybowski's generalized eruptive keratoacanthoma which demonstrates the characteristic features of this rare condition. The recurring nature of the eruption each summer supports the suggestion that UV irradiation may act as a precipitating factor in eruptive keratoacanthoma.
The oral retinoids isotretinoin and etretinate are uniquely effective in the treatment of severe cystic acne and keratinisation disorders. Because of their known teratogenicity, there are strict prescription guidelines, but exposure during pregnancy still occurs. A dedicated effort by women and their clinicians is required, involving patient selection, education and informed consent, detailed contraceptive counselling, and careful monitoring and management, including pregnancy testing before commencement of therapy.
The oral retinoids, isotretinoin and etretinate, are highly teratogenic drugs which have been available in Australia since 1985 because of their unique effectiveness in severe cystic acne, psoriasis and other keratinization disorders. Only dermatologists can prescribe them, but in spite of strict guidelines by the manufacturers and the College of Dermatologists, exposed pregnancies have occurred. We attempted to determine the circumstances of exposure to these drugs for the 18 pregnancies terminated in South Australia in 1985-1993, using questionnaires to medical practitioners who notified the terminations under legislation. The main reason for their occurrence was the lack of compliance with the use of effective contraception by the women. In South Australia, some prescriptions of oral retinoids by unauthorized doctors have been dispensed during this period. Using statistics on prescriptions dispensed, an estimate was made of 1 termination of pregnancy for 319 courses of treatment for women with isotretinoin. Extension of guidelines for prescription and more detailed counselling in relation to the use of contraception are recommended. It is also suggested that doctors intending to recommend terminations obtain consent to discuss exposure with the dermatologists concerned, who may not be aware of the exposed pregnancy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
