Thyroid cartilage at the suprasternal notch with low situated thyroid gland.

The thyroid cartilage and thyroid gland forming a lump at the suprasternal notch is a surprising congenital anomaly which I believe has not been previously reported. A case with co-existent low hyoid bone, pharyngo-oesophageal junction and intrathoracic cricoid cartilage with no cervical trachea is presented. Its pathogenesis is suggested and its surgical importance is discussed.
