Leishmaniasis of the eyelid mimicking an infundibular cyst and review of the literature on ocular leishmaniasis

Abstract

Cutaneous leishmaniasis is an infection caused by protozoa belonging to the genus Leishmania. The disease is transmitted by sandflies. Reservoirs are represented by dogs, mice, rats, and wild rodents. Cutaneous leishmaniasis is usually characterized by a single, polymorphous lesion located in an uncovered area. We report a case of cutaneous leishmaniasis localized on the left upper eyelid in a 36-year-old woman. The disease was characterized by a single, asymptomatic nodule, which was clinically diagnosed as an inflammatory infundibular cyst. The lesion was excised surgically. Histopathological examination showed an inflammatory infiltrate consisting of lymphocytes, histiocytes, and plasma cells. Several Leishmania spp amastigotes were observed in the cytoplasm of macrophages. Culture examination on Novy-MacNeal-Nicolle medium was positive for Leishmania spp. PCR was positive for Leishmania infantum. No relapses were observed during follow-up (17 months). The purpose of this report is to emphasize the changeability of clinical presentation in cutaneous leishmaniasis.

Slowly Progressive Keratouveitis in a Patient with Known Systemic Leishmaniasis and HIV

“…The most frequent ocular manifestation is cutaneous eyelid disease, 3 though there are a few reports of conjunctival disease, fulminant anterior uveitis, and posterior uveitis. 4,5 The anterior uveitis caused by Leishmania is granulomatous in nature 4,5 and, despite intensive systemic treatment, there is a high degree of ocular morbidity with many cases resulting in blindness.…”

Cutaneous Leishmaniasis of the Eyelid: A Case Report

“…The most commonly involved sites are exposed areas. The face is the usual site in the cutaneous leishmaniasis; however, the low incidence on the eyelid is attributed to the frequent movements of the eyelid, which deter the insect from biting the skin in this region [5]. …”

Parasitic Eye Disease in India and the World- A Major Review

“…The disease is spread by the sand flies of the genus Phlebotomus and Lutzomyia. 17 It causes fever (Kala-azar) with darkening of skin, reduction in immunity, occurrence of opportunistic infections, occurrence of tuberculosis in many patients and ultimately wasting, emaciation and death. It can occur as co-infection in HIV-affected individuals.…”
