Lichenoid eruption following penicillamine. A case report with some biochemical observations

The phenomenon of lichenoid eruptions following medication with antimalarial, anti-arthritis and antibacterial medication is well documented in the literature. We report here the first case to be described as a result of anti-arthritis treatment with penicillamine, together with some biochemical studies of the effect of this compound on the enzyme glucose-6-phosphate dehydrogenase.
