Old World eyelid cutaneous leishmaniasis: a case report

Abstract

Leishmania is a protozoa that may infect the skin, mucous, and viscera. The geographical distribution of cutaneous leishmaniasis (CL) is mainly determined by the sandfly vectors. The Old World type is mainly attributed to Leishmania major and Leishmania tropica, and in South of Europe only to Leishmania infantum. A 63-year-old woman, who noted a pimple on the external third of the left upper eyelid 6 months before. The lesion was nodular, well-defined and measured 1.1 cm in diameter and in height, simulating a basal cell carcinoma. It was surgically excised. CL diagnosis was made upon the histologic examination, which showed histiocytes with intracellular leishmania organisms. At 2 years followup, no evidence exists of cutaneous, mucous, or visceral involvement. Apart from carcinomas, nodular lesions with central ulceration are rare on the eyelid. A single cutaneous lesion of leishmania (oriental sore) has to be considered in the differential diagnosis, along with malignant eyelid neoplasms.
