Tegumentary leishmaniasis (TL) includes cutaneous (CL) and mucosal (ML) leishmaniasis; despite being endemic in southern Europe, it is often underdiagnosed and underreported. This study aimed to retrospectively examine data collected from patients with TL in a selected area of northeastern Italy (Emilia-Romagna region, RER). A network of 10 diagnostic units within RER was established, and TL cases diagnosed in RER from 2017 to 2020 were evaluated. A total of 135 TL cases were collected (62% male, 38% female); patients ranged from 1 to 84 years, with a median age of 57. Among these cases, 113 (84%) were notified to the public health authorities. The average annual incidence of TL was 0.76 cases per 100,000 inhabitants. Infections were acquired within the RER in 84% of cases; the 113 autochthonous cases were distributed in the foothills areas of the region. We provide evidence of a defined spatial distribution of TL cases in a selected area of northeastern Italy, as well as a relevant number of ML cases. Our observations suggest the need to raise awareness about TL among clinicians and pathologists, promote the molecular confirmation of cases by reference laboratories, and encourage the establishment of surveillance networks for this neglected disease.
