Lepromatous leprosy in darker-skinned individuals is characterized by widespread skin lesions, nodules, and thickening of the skin, often leading to facial disfigurement and loss of sensation. The condition, which is the most severe form of leprosy, can also cause nerve damage and deformities due to the high bacterial load. Treatment involves a multi-drug therapy (MDT) regimen consisting of dapsone, rifampicin, and clofazimine, which helps to reduce the bacterial load and prevent complications, with close monitoring to manage side effects and potential nerve damage.
