Abstract
    A two-year-old neutered Shih Tzu male dog was referred to Urmia University Veterinary Hospital with the owner's complaint of a lump in the lumbar area with dimensions of 20×30×30 mm. In the evaluation of the mass, its consistency was relatively firm and painless, and no sign of inflammation, wound, or bleeding was seen. In the hematology and biochemical analysis, no abnormal findings were observed except mild anemia. According to the favorable clinical condition of the animal and the result of cytology, it was suggested to remove the mass by surgical method. Histopathological examination, which confirmed cutaneous myxoma, showed that the mass had no capsule and consisted of immature fibroblasts with different shapes of nuclei, including spindle, plump, and round, which were loosely arranged in a myxoid stroma. Despite the prominence of breed predisposition in Doberman pinschers and German shepherds, there are limited reports of myxoma in other breeds. This clinical report, which dealt with the occurrence of cutaneous myxoma in a young Shih Tzu dog, showed that this tumor does not necessarily occur in animals over eight years of age, and there is no breed limitation in its occurrence.
