Drug induced autoimmune syndromes have been recognized for many years. The classical presentation is that of drug-induced lupus, a generally milder version of the idiopathic disorder that is associated with production of antihistone antibodies. This pattern is now changing, in part due to the many new drugs that have been introduced into clinical practice for treatment of autoimmune diseases, including both conventional pharmaceuticals and biologicals. The number and complexity of drug-induced autoimmune syndromes has increased, and many are now associated with autoantibodies that have been classically defined as limited to idiopathic disease states. Furthermore, some of these drug-induced syndromes have life-threatening complications, so that recognition of drug-induced disease has become more difficult at a time when it is more urgent to establish a correct diagnosis. Many reports are limited to case descriptions, and few controlled investigations have been carried out. Nevertheless, it is possible to derive an approach to considering possible mechanisms by which these processes may take place. This chapter will consider these proposed mechanisms, using some of the implicated drugs to illustrate possible pathogenetic pathways.

Sweet's syndrome is an acute febrile neutrophilic dermatosis which usually presents as an idiopathic disorder but can also be drug induced, associated with hematopoetic malignancies and myelodysplastic disorders, and more, infrequently, observed in autoimmune disorders. Sweet's syndrome has been reported in three cases of neonatal lupus, three cases of hydralazine-induced lupus in adults, and in nine pediatric and adult systemic lupus erythematosus (SLE) patients. We describe three additional adult cases of Sweet's associated with SLE and provide a focused review on nondrug-induced, nonneonatal SLE and Sweet's. In two of three new cases, as in the majority of prior cases, the skin rash of Sweet's paralleled underlying SLE disease activity. The pathogenesis of Sweet's remains elusive, but evidence suggests that cytokine dysregulation may be central to the clinical and pathological changes in this condition, as well as in SLE. Further research is needed to define the exact relationship between the two conditions.

Dermal mucinosis is characterized by the deposition of glycosaminoglycans (mucin), either focally or diffusely within the dermis. This may occur as a primary idiopathic disorder or secondary to several dermatoses, most notably lupus erythematous, scleroderma, and dermatomyositis. The authors present an unusual finding of dermal mucinosis in association with chronic sclerodermoid graft-versus-host disease.
