The differential diagnosis of cutaneous leishmaniasis includes arthropod bites, basal cell carcinoma (BCC) and other malignancies. BCC is the most common form of skin cancer. We present a case of cutaneous leishmaniasis resistant to standard intralesional glucantime injection in an immunocompromised patient, which was proved to be BCC after surgical excision.KEYWORDS: Leishmaniasis, Basal Cell Carcinoma, Glucantime.
