Spectacle frame induced chemical leucoderma: A case report

Chemical leucoderma is an acquired hypopigmented dermatosis caused by repeated exposure to specific chemical compounds, notably the aromatic or aliphatic derivatives of phenols andcatechols which are commonly present in the rubber and plastic materials. Herein, we report a case of chemical leucoderma in a 55-year-old male, appearing bilaterally over the retroauricular areas, which appeared afte...

Leucoderma in early syphilis.

CASE 1 A 25-year-old man first noticed depigmented lesions on the face and neck; a few days later he developed asymptomatic erythematous papular and scaly lesions over the trunk and extremities, and moist papular lesions on the scrotal skin. Two weeks later when he reported to us, some of the trunk lesions had also become depigmented. Four months earlier after an extramarital sexual exposure, t...

Cell proliferation and chemical carcinogenesis: symposium overview.

Cancer, by definition, is a proliferative disease. The fundamental scientific issue explored at the international symposium "Cell Proliferation and Chemical Carcinogenesis" was the impact of chemically enhanced cell proliferation on the dynamic carcinogenic processes. This conference, held at the National Institute of Environmental Health Sciences January 14-16, 1992, provided an open forum for...
