In cats, ESOSA has been reported to arise from orbital, ocular, intestinal, mammary and subcutaneous locations. Subcutaneous ESOSA occurs most commonly at sites used for vaccination including interscapular, dorsal lumbar or thigh areas. Previous reports of feline cases have not documented the use of advanced diagnostic imaging to exclude a primary bone tumour.<\/jats:p><\/jats:sec><jats:sec><jats:title>Objective<\/jats:title><jats:p>To describe the clinicopathological and advanced imaging findings of a subcutaneous ESOSA occurring in a metatarsal footpad of a cat and to report the one year follow\u2010up status.<\/jats:p><\/jats:sec><jats:sec><jats:title>Animal<\/jats:title><jats:p>A 9\u2010year\u2010old neutered male domestic short hair cat.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Physical, abdominal ultrasonographic and computed tomographic examinations, and excisional biopsy for histopathological and immunohistochemical evaluation.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The cat presented with mild focal erythematous swelling of the left metatarsal pad.
