Background: Indians have a wide variety of skin color. Colored skin is more prone to a number of hyperpigmented skin conditions. This study was undertaken to study the prevalence and pattern of various hyperpigmented skin conditions in Western Uttar Pradesh, India.
Methods: A retrospective record based analysis of all patients presenting with complaints of skin hyperpigmentation during a period of one year from January to December 2016 was done. The diagnosis of all such conditions was noted and percentage calculated. The diseases were categorized into one of the etiological groups.
Results: Melasma was the commonest cause of hyperpigmentation seen in 2396 (33.63%) patients followed by post inflammatory hyperpigmentation in 892 (12.52%) patients, acquired melanocytic nevi in 533 (7.48%) patients, lichen planus pigmentosus in 525 (7.37%) patients and ephelids in 491 (6.89%) patients. As an etiologic group, endocrinal cause was the commonest due to the inclusion of melasma in the group.
Conclusion: Melasma was the leading cause of hyperpigmentation. Post inflammatory hyperpigmentation and lichen planus pigmentosus are important causes of pigmentation in colored skin, unlike in fair skinned individuals.
