Ectopic submandibular thyroid tissue is a rare entity and poses difficult diagnostic and management problems. The first case of ectopic submandibular thyroid with a normotopic multinodular goitre is presented

We report a case of an abscess from an ’ectopic’ accessory parotid gland in the cheek demonstrated by sialography and computed tomography (CT). The accessory parotid gland was ectopically located anterolateral to the masseter muscle and isolated from the main parotid gland. The orifice and ductal system of the ectopic accessory parotid gland were separated from those of Stensen’s duct. The abscess developed from this ectopic accessory gland, and the main parotid gland was free of inflammation. Using sialography and CT, we confirmed the presence of this ectopic accessory gland.

Ectopic thymic tissue in the neck is rarely reported in medical literature. This paper presents the case of a young female, who presented with a soft, fluctuating mass in the left side of her neck. Surgical excision revealed an ectopic thymic cyst. Ectopic thymic tissue may be an infrequent finding, but it should be included in the differential diagnosis of neck masses, especially in children. This case report is accompanied by a short review of the relative literature.

Ectopic thyroid tissue within the submucosa of the trachea is a rare cause of upper airway obstruction. Primary neoplasms arising from such thyroid nests are rare. This report describes a case of tall cell variant of papillary carcinoma arising from ectopic thyroid tissue in the trachea.

Ectopic thyroid is an uncommon embryological aberrationcharacterized by the presence of thyroid tissue at a site other than in its usual pretracheal region. Usually it occurs along the path of descent of the developing thyroid primodium from the foramen caecum, commonest being lingual followed by sublingual and in the anterior midline of neck at, or below, the level of the hyoid bone. It is unusual for lingual thyroid to present simultaneously with another ectopic thyroid; reported here are two such cases.
