*Cutaneous infection may become a part of systemic infection
*Mostly caused by [[Protozoa|''Leishmania'']]
*Transmitted by [[Insecta|sandflies]]
*Occurs in dogs, cats and rodents (also humans)
*Grossly in dog:
**Generalised alopecia
**Silvery white scales
**Nodules and ulcers if more severe
**Mainly on muzzle, ears and eyes where flies feed
*Microscopically:
**[[Skin Glossary - Pathology|Hyperkeratosis, parakeratosis, crusts]]
**Granulomatous nodules in dermis
**Macrophages, some lymphocytes and plasma cells - periadnexal pattern, may affect sebaceous glands
**Organisms may be found extra or intracellularly
