Generalized hyperpigmentation in Wilson's disease: An unusual association

Wilson's disease, an autosomal recessive disorder of copper metabolism, most commonly presents either with hepatic or neurological features. But, it may sometimes have certain atypical presentations posing diagnostic difficulties. We report here a case of Wilson's disease presenting with generalized hyperpigmentation of skin who also developed neurological manifestations subsequently. We aim to highlight the importance of keeping Wilson's disease as one of the differentials in patients who present with hyperpigmentation and neurological symptoms compatible with copper deposits in the central nervous system and proceed for investigations accordingly.
