[Skin manifestations in leishmaniasis in dogs]

In 23 dogs with clinically apparent leishmaniosis the observed skin lesions were analyzed with respect to appearance, type and localization. The diagnosis could be established in 22 cases by cytological or histological demonstration of the parasite, positive serodiagnosis and typical clinical findings. The following lesions-in order of frequency-were found on the mucous membranes and the skin including foot pads and nails as well as on the mucocutaneous junctions: 1) desquamation with formation of characteristical light scales, 2) localized or symmetrical alopezia, 3) erythema, 4) ulceration and depigmentation was seen especially at the acrae, 5) granulomatous nodules and pustular dermatitis were less common. Hyperkeratosis of the foot pads, onychogriposis and onychorrhexia occurred at the paws. These various cutaneous manifestations of leishmaniosis should be considered in the differential diagnosis of canine skin disease.
