Ectopic thyroid is a rare developmental anomaly which may be either asymptomatic or present with thyroid dysfunction as well as pressure symptoms. Here we present a novel case of thyrotoxicosis associated with a hypopharyngeal multinodular thyroid in a female. Removal of the ectopic thyroid led to normalization of the thyroid status.
During vertebrate development, the thyroid gland undergoes a unique relocalisation from its site of induction to a distant species-specific position in the cervical mesenchyme. We have analysed thyroid morphogenesis in wild-type and mutant zebrafish and mice, and find that localisation of growing thyroid tissue along the anteroposterior axis in zebrafish is linked to the development of the vent...
Lingual thyroid is an uncommon condition and cases accompanying hemiagenesis are rarely documented. Patients with usually asymptomatic generally diagnosed incidentally. Herein, we reported the case of ectopic lingual euthyroidism presented regional symptoms.
INTRODUCTION A separate substernal goitre which is not continuous with the main cervical thyroid proves a unique challenge for resection. A trans-cervical approach is preferred but may be hazardous due to the possibility of ectopic thyroid tissue with alternate blood supply. PRESENTATION OF CASE A 72year old female who had a previous left hemithyroidectomy presents with a symptomatic central ...
sertion, and dysgenesis of the iridocorneal angle often leading to glaucoma. Although the exact etiology is unknown, CIE arises from late developmental arrest of the posterior migration of neural crest cells. Likewise, abnormal migration and differentiation of cells derived from the neural crest are implied in IND, a disease of the submucous enteric plexus characterized histologically by a larg...
