Adenoid cystic carcinoma of arytenoid: a rare tumor at a rare site
Keywords:Pedunculated primary adenoid cystic carcinoma, Pedunculated polyp of arytenoid, Arytenoid
Pedunculated primary adenoid cystic carcinoma of larynx is an uncommon form of malignant neoplasm. This case is an extremely rare entity and hence reported. Until today this type of carcinoma is not reported in medical literature. A 55 year old female patient came with 6 months history of dyspnoea and foreign body sensation in throat and occasional change of voice. Micro laryngeal surgical excision of the pedunculated polyp was done under general anaesthesia using diathermy cautery and specimen was sent for histopathological examination, perineural spread of the tumour is highlighted. The pedunculated polyp from the arytenoid looked like a benign lesion and histopathological examination showed the lesion to be adenoid cystic carcinoma.
