Abstract
Leishmaniasis is an infectious zoonotic disease caused by protozoan parasites of the genus Leishmania. In the Mediterranean basin, leishmaniasis is caused by Leishmania infantum and transmitted by bites of sandflies of the genus Phlebotomus, with the dog as the main reservoir host. The most common form is cutaneous leishmaniasis (CL), although visceral cases also occur. The aim of this study was to assess the underestimation of CL in an endemic Mediterranean region. Thus, a retrospective study was performed on all CL cases diagnosed and treated in the Dermatology Service of Manacor Hospital (Majorca, Balearic Islands), and the data obtained were compared with those of local government epidemiological bulletins for the same period. The different clinical presentations were compiled, and data related to sex, age, and lesion type and number were analyzed. The results reveal a clear sub-notification, which indicates that the real incidence of human CL in this area is unknown.
