Post kala-azar dermal leishmaniasis (PKDL) is a skin complication resulting from infection with Leishmania donovani (LD) parasite. It mostly affects individuals who have previously suffered from visceral leishmaniasis (VL) caused by LD. In some cases, PKDL develops among people infected with LD, but do not show any symptoms of VL. Clinical presentation includes hypopigmented macules/papules/nodules or polymorphic lesions (combination of two or more lesions). Except for skin lesions, PKDL patients are generally healthy and usually do not seek medical care. These patients play an important role in interepidemic transmission of the infection and subsequent VL outbreak. Therefore, proper diagnosis and treatment of PKDL patients is important for the control of VL in endemic countries, especially in the Indian subcontinent where VL is anthroponotic. Here, we report the challenges in the estimation of PKDL burden, its diagnosis, and treatment, and suggest possible solutions based on recent literature, reports, published manuals, and web-based information.
