Squamous cell carcinoma in the posterior larynx: A rare localization of supraglottic T1 laryngeal cancer. Case report.

Laryngeal squamous cell carcinoma (SCC) is a common malignancy of the head and neck, typically presenting in older patients with a history of smoking or alcohol use. However, its progression can be unpredictable, with cases of long-term dormancy followed by rapid progression. We report a case of a 71-year-old male with an 18-year history of otolaryngological treatment who presented with a newly diagnosed laryngeal SCC after multiple benign findings in previous laryngoscopies. The patient underwent CO2 laser excision of the tumour, and subsequent histopathological examination confirmed the presence of SCC. Follow-up imaging and microlaryngoscopy revealed no residual tumour or metastasis. The patient remains under surveillance.
