Voluminous Amygdaloid Cyst: A Case Report

Abstract

Amygdaloid cysts also known as lymphoepithelial cysts or branchial cleft cysts are rare and benign dysembryological cystic tumors that develop in the antero-lateral part of the neck; they represent 2% of laterocervical tumors of the neck. Originating from the second branchial cleft, due to the persistence of the cervical sinus during the differentiation of the branchial apparatus. We report the case of a 34-year-old man who consulted for a huge right laterocervical swelling that had been gradually increasing in volume for 8 months without any other associated symptoms. A cervicotomy and a complete resection of the cyst was performed, histopathological examination of the surgical specimen confirmed the diagnosis of the amygdaloid cyst without signs of malignancy. The aims of this study are to analyze the anatomo-clinical features and to discuss the modalities of care and the therapeutic indications of this affection.
