A histiocytoma in the dog is a benign tumor that originates from histiocytes. most likely epidermal Langerhans cells of antigen-presenting cell lineage.[1] Most commonly histiocytomas are found in young dogs and appear as a small, solitary, hairless lump. Ulceration of the mass is common. Diagnosis is made through cytology of the mass. Most histiocytomas will regress within two or three months. Surgical removal may be necessary if the tumor does not regress or if it is growing rapidly to a large size. Histiocytomas can also be treated with an intralesional injection of a corticosteroid, but this is not always successful.
