Two cases of feline leishmaniosis in Switzerland.

Two cats with Leishmania species infections were investigated. The first had been imported from Spain with a non-healing, ulcerated nodule on a hindleg. The presence of Leishmania species was detected by histopathology and pcr on samples of skin. The lesion was unresponsive to treatment with allopurinol for three months but the cat was treated successfully by removing the lesion surgically. The second cat had lived in both Spain and Switzerland, and had a history of recurrent skin lesions on its head and neck. A diagnosis of pemphigus foliaceus was made on the basis of histopathology, but Leishmania species serology (elisa) and pcr of skin were positive, leading to a diagnosis of a Leishmania species infection combined with pemphigus foliaceus.
