Squamous cell carcinoma is the most common tumor of the equine stomach.[1]. It can affect the cardia and upper squamous regions of the stomach, resulting in a persistent mild colic, commonly seen soon after feeding. The tumor can invade and metastasize to lymph nodes, the lungs and regions palpable on rectal examination.[1] The main clinical signs include weight loss and general ill health.(Merck) Hypertrophic osteopathy associated with this neoplastic disease has been reported in one horse.[2] Diagnosis is made by exclusion of other causes of weight loss and gastroscopy. In most cases, surgical resection is not possible[3] and the prognosis is grave.
