In intra-laryngeal extension, patients may present with symptoms such as hoarseness, dyspnea, and dysphagia, and it is challenging to differentiate endolaryngeal TGDCs from laryngeal cystic masses such as saccular cysts and laryngoceles. Also, malignancies arising from TGDCs are uncommon, and there is no clear consensus on their treatment. This study aimed to emphasize that TGDCs may also be present in the differential diagnosis of cystic laryngeal lesions by presenting our case of TGDC papillary carcinoma with intralaryngeal extension in a 37-year-old female patient.eninfo:eu-repo/semantics/openAccessArticle10.24179/kbbbbc.2022-904143042322361169155
