Ticlopidine hydrochloride Received: Jul 5, 2013 inhibits platelet aggregation and is widely used for the prevention of thrombosis. There have been only a Revised: Dec 30, 2013 few reports of ticlopidine-induced lupus. Here, we review 13 previously reported cases and describe the Accepted: Jan 2, 2014 case of a 71-year-old man with ticlopidine-induced subacute cutaneous lupus erythematosus. His diagnosis was supported by the appearance of papulosquamous skin lesions on sun-exposed areas and Keywords: detectable anti-Ro/SS-A antibodies, shortly after drug initiation as well as the gradual resolution of these lupus erythematosus symptoms after the discontinuation of ticlopidine. Our case highlights that when a patient presents with ticlopidine subacute cutaneous lupus erythematosus-like skin lesions, ticlopidine should be considered as a po- tential causative agent.
