A case of canine cutaneous reactive histiocytosis over the body trunk in an adult pit bull terrier

Abstract

Abstract The objective of this report is to present a case of canine cutaneous reactive histiocytosis with a high number of dendritic cells. A 7‐year‐old male pit bull terrier was presented with a 5‐month history of skin nodules and plaques on the trunk of varying diameter, along with corneal oedema and anterior uveitis. No other clinical signs were observed. Histopathological findings showed that the main cell type of the dermal subcutaneous infiltrate was histiocytoid cells, with a high number of dendritic cells. Treatment with systemic use of cyclosporine A for 6 weeks was effective.
