Lithium-induced Linear Psoriasis: A Rare Presentation

Shimona Garg et al. J Clin Aesthet Dermatol. 2019 Apr.

Abstract

Atypical forms of psoriasis are frequently seen. However, linear psoriasis precipitated by drugs is extremely rare. We report a case of an adult woman who presented with lithium-induced unilateral psoriasis arranged in Blaschko lines on the left leg. A brief discussion on etiology and differential diagnosis is included, as well as treatment methods.

Keywords: Blaschko lines; Psoriasis; linear; lithium.
