Autoimmune Hepatitis and Systemic Lupus Erythematosus Overlap Syndrome: A Case Report and Literature Review.

Autoimmune hepatitis-systemic lupus erythematosus (AIH-SLE) overlap syndrome is a rare disease entity. In some cases, a delay in the occurrence of overlap is observed, where the diagnosis of one of the conditions precedes the other. However, other patients have features of both disorders simultaneously upon initial presentation, leading to a direct diagnosis of AIH-SLE overlap syndrome.
