Argyria an unrecognized cause of cutaneous pigmentation in Indian patients: A case series and review of the literature.

ABSTRACT

Argyria is an uncommon grey-blue pigmentation of skin and mucous membranes caused by prolonged silver exposure. The impetus behind this review is our experience with cases of generalized argyria resulting from a uniquely Indian socio-cultural practice and belief that it is under reported. Our objective is to increase the awareness for this esoteric entity through a review of the pertinent literature and to highlight clinical and histological features using our four well worked-up cases as examples.
