Background: Human leishmaniasis is on increase in the Mediterranean Europe. However, the exact prevalence of cutaneous leishmaniasis (CL) is largely unknown as underdiagnosis and under reporting are common.
Objective: To evaluate epidemiological, clinicopathological and microbiological aspects of CL cases occurring in the Bologna Province, north-eastern Italy.
Methods: We performed a retrospective, observational study on CL cases diagnosed in the Bologna Province between January 2013 and December 2015.
Results: During 2013-2015, 30 cases of CL were identified in the Bologna Province with an average incidence of 1.00/100 000, with an increase of fourfold to 12-fold as compared to previous years. 16 of 30 (53%) CL cases presented as single, typical lesions. CL diagnosis was carried out by histological and molecular techniques, although in 7 of 29 (24%) PCR-positive cases, amastigotes were not visible on histology.
Conclusions: We report new evidence of CL cases in a focal area of north-eastern Italy in 2013-2015. Our study highlights the importance of CL surveillance in the Mediterranean basin and emphasizes the need for the molecular laboratory surveillance of CL in endemic areas.
