A case of canine cutaneous histiocytoma under neck skin is reported. A 7-year-old male bulldog was present- ed with a firm subcutaneous nodule under neck skin for more than 1 month. Histopathological examination showed masses of tumor cells consisting of fibroblast- and histiocyte-like cells containing haemosiderin, and there were multi- focal areas of irregular cavities in the masses full of red cells without endothelial lining. These findings were consistent with all histiocytoma.
