Summary Lichen planus pigmentosus is a fairly common disorder of pigmentation in Indians, but reports comprising a sizeable number of patients are lacking in the literature. We now describe the clinical and epidemiological features and histopathological findings for 124 lichen planus pigmentosus patients. A retrospective analysis of medical records of patients attending our centre during the past 12 years was undertaken. Of the 124 patients (56 male, 68 female), the majority (48.4%) had the disease for 6 months to 3 years. The face and neck were the commonest sites affected with pigmentation varying from slate grey to brownish‐black. The pattern of pigmentation was mostly diffuse (77.4%), followed by reticular (9.7%), blotchy (7.3%) and perifollicular (5.6%). Lichen planus was noted in 19 patients with typical histopathological changes of the disorder. Lichen planus pigmentosus, a distinct clinical entity commonly encountered in the Indian population, should be considered in the spectrum of lichenoid disorders as a variant of lichen planus.
