Abstract:
Ultimobranchial body (UBB) remnant was considered as an enigma till the last few years, then it was recognized as a necessary organ where it is the origin of the parafollicular cells. The samples were fixed and processed for the histological and electron microscopic examination. Macroscopically, the UBB remnant appeared as a white mass at the end of the cranial one-third of the thyroid lobe. It was composed of solid cell nest, cluster of cells and small thyroid follicles. Transmission electron microscope showed some round cells containing euchromatic nuclei, numerous parafollicular cells with darkly stained granules and paler ones. It also showed some mast cells with heterochromatic nuclei and large darkly stained granules. The parafollicular cells were distributed throughout the thyroid gland but concentrated within the UBB remnant. To our knowledge, our findings represent very unique histological manifestations specially the ultra-structural ones which revealed an original finding about the new clear type of cells suggested to be a UBB remnant and ensure those of the light microscope.
