Histopathologic examination of the biopsy specimen showed epidermal hyperplasia with a diffuse superficial and deep inflammatory infiltrate and pseudoepitheliomatous epidermal hyperplasia with a predominantly lymphocytic dermal infiltrate and parasitized macrophages (Figure 2, original magnification ×40). There were numerous 2- to 4-μm round to oval organisms, with kinetoplasts located at the periphery of vacuolated cytoplasm of macrophages, consistent with amastigotes (Figure 3), original magnification ×600). These findings supported the diagnosis of cutaneous leishmaniasis, eventually speciated as Leishmania panamensis.
