ABSTRACT

Cutaneous leishmaniasis is endemic in many countries, but nail unit involvement has rarely been reported. It is caused by an intracellular protozoan of the genus Leishmania, which is frequent in fingers, although it was also described in the great toe. The lesion appears as a chronic paronychia, ulceration, or may even be verrucous. Patients who live or have visited endemic areas with other skin lesions suggestive and unresponsive to antibiotic therapy are suspicious. Slit-skin smear, biopsy, and molecular diagnostic tests confirm the diagnosis.
