Enorme kyste amygdaloïde cervical à propos d'un cas

Abstract: Les kystes amygdaloïdes sont des tumeurs bénignes kystiques dysembryologiques qui se développent au niveau de la partie antéro-latérale du cou, ils représentent 2% des tumeurs latéro-cervicales du cou, ils comptent parmi les plus fréquentes des anomalies branchiales, ils représentent 6,1 à 85,2% des anomalies de la deuxième fente. Ils sont dus à la persistance du sinus cervical au cours de la différenciation de l'appareil branchial. Ils se manifestent par une tuméfaction latéro-cervicale située au bord antérie… Show more

“…Histologically, the branchial cyst is lined by an epithelium of different types, most often squamous, but it can also be a ciliated columnar epithelium of ectodermal origin. Some authors consider the presence of keratin and lymphoid tissue to be mandatory criteria for the diagnosis of a branchial cyst [ 9 , 10 ]. Malignant transformation within the branchial cyst has been described in the literature but remains exceptional, only 15 cases have been published in the world literature, including 4 carcinomas in situ and 11 infiltrating squamous cell carcinomas [ 11 ].…”

“…Anomalies of the second cleft most often sit next to the anterior edge of the sternocleidomastoid muscle at the level of its middle third at the height of the hyoid bone. Amygdaloid cysts are among the most frequent anomalies of the second branchial arch, up to 85% of cases [1] [2]. Although it is a congenital anomaly, these cysts of the second branchial arch in adults are discovered late during the 2 nd and 3 rd decades of life without any sexual predominance.…”

“…These cystic malformations represent a frequent reason for consultation in pediatrics but they can also be found in adults. The amygdaloid cyst is one of the most frequent branchial anomalies, in particular up to 85% of those anomalies originate from the second bronchial arch [1] [2]. The circumstances of discovery are of two kinds, either discovery of a cervical swelling and/or a fistulous orifice chronic skin disease, or during an inaugural complication, with discovery of a cervical cystic swelling after an acute pharyngeal infectious episode.…”
