The attending physician should therefore always be informed if aplanned therapy involves off-label use. Previously approved alternatives should be considered and patients should be adequately informed. It can be stated that the enormous developments over the last few years and the increasingly good evidence offer in many cases very promising systemic treatment concepts despite the frequent lack of clinical studies in the field of dermatology. However, the often necessary off-label use can cause difficulties in everyday clinical practice. The attending physician should therefore always be informed if a planned therapy involves off-label use. Previously approved alternatives should be considered and patients should be adequately informed.The term cutaneous pseudolymphoma (C-PSL) is defined in the literature as a benign, reactive lymphoproliferation that clinically and/or histopathologically imitates cutaneous lymphoma. The exact etiopathogenesis has not been fully elucidated to date. A distinction is made between primary, idiopathic PSL without an identifiable cause and secondary PSL with a known stimulus. We report the occurrence of pseudolymphoma after treatment with medicinal leeches (hirudotherapy). To the best of our knowledge, a total of only nine cases of cutaneous PSL after hirudotherapy have been reported in the literature to date.The transmission of pathogens that cause leishmaniases occurs by the bite of female sand flies (Diptera Psychodidae) in their vertebrate hosts, which makes the identification of their bloodmeal sources an important step for the control and epidemiology of these diseases. In Brazil, the state of Roraima has a great diversity of sand flies, vertebrate hosts, and protozoan Leishmania, but little is known about the host blood-feeding preferences of sand flies. Thus, we evaluated the bloodme
