Acquired ichthyosis associated with an overlap syndrome of systemic sclerosis and systemic lupus erythematosus.

Acquired ichthyosis is a condition accompanying many systemic illnesses such as lymphoma, sarcoidosis, dermatomyositis and systemic lupus erythematosus (SLE). Overlap syndromes are defined as clinical entities which satisfy each of the diagnostic criteria of two different connective tissue diseases concurrently or consecutively. The coexistence of SLE with systemic sclerosis has been very rarely reported. We describe a 33-year-old woman with an overlap syndrome consisting of systemic sclerosis and SLE who developed ichthyosis on her extremities.
