The ultimobranchial remnants were investigated in the thyroid gland of the adult camel. The vestiges of this structure were appeared in various forms and shapes. The most common shapes were large follicles with various arts, distended cysts, solid cell nests and small irregular follicles. The lining epithelium of those follicles and cysts was found to be variable. The solid cell nests were represented by masses of basophilic epithelial cells surrounded with connective tissue. Immunohistochemical staining of the ultimobranchial remnants against calcitonin was performed and different intensities were recorded. The most intense stain was detected at the solid cell nests. Our immunohistochemical findings confirm that the remnants of the ultimobranchial body is also present in the thyroid glands of adult camel
