Disseminated giant porokeratosis and porokeratosis of M ibelli in B ankura and B ardhaman districts, W est B engal, I ndia

Porokeratosis of Mibelli ( PM ) is a rare genodermatosis. It is caused by proliferation of abnormal clones of epidermal cells in response to several stimuli, the most important of which is sunlight. Giant porokeratosis is thought to be a variant of PM . We report two cases of disseminated PM and one case of disseminated giant porokeratosis from the B ankura and Bardhaman districts of W est B engal in I ndia; presenting to a single observer in the summer of 2012. Interestingly we have noted that the majority of cases of porokeratosis in India have been reported from W est B engal. Few patients with a single lesion of giant porokeratosis have been reported in world literature. As far as we know, this is the first case report of disseminated giant porokeratosis in world literature.
