Cutaneous leishmaniasis and leprosy are diseases both caused by intracellular pathogens that represent a major health predicament even today. Both these diseases have some characteristics in common, such as the involvement of mucocutaneous tissue, a course with a chronic granulomatous response, a broad clinical spectrum in relation to the host's immunity, and they often affect the poor population in tropical countries. Co-infection of the two diseases, although known to occur, is rarely encountered and reported. Even though new cases of leprosy are diagnosed in the region of coastal Karnataka of India, cutaneous leishmaniasis is rarely reported. We hereby describe a patient who presented with concurrent leprosy and diffuse cutaneous leishmaniasis.

Dermatosis papulosa nigra is a benign unaesthetic condition seen in Fitzpatrick skin types IV-VI. The diagnosis is mainly clinical; however, in a few cases histopathology and dermoscopy aid in differentiating it from other benign and malignant tumors. Dermoscopy, in particular, being a noninvasive investigative moiety is a rapid and accurate diagnostic tool.
