Abstract:
During embryonic development the thyroid gland migrates through the thyroglossal duct from the pharyngeal endoderm to the anterior cervical region. The final step in this process is the total obliteration of the thyroglossal duct. A case is presented of a patient with a thyroglossal cyst together with a complete failure of the obliteration of the duct, which caused regurgitations of mucopurulent material after the expression of the cyst. This indicates a complete failure of the obliterative process. To the best of our knowledge, this phenomenon has not been described previously in the literature.

Nasopharynx
The nasopharynx, bordered by the conchae of the nasal cavity, serves exclusively as an air conduit. In its superior region, the pharyngeal tonsils or adenoids are located. These tonsils are clusters of lymphoid reticular tissue akin to a lymph node. The precise...
