Abstract

Polymorphous low‑grade adenocarcinoma is an uncommon malignant tumor derived from the terminal duct cells of the salivary glands. The present study described a rare case of polymorphous low‑grade adenocarcinoma, T2N0M0 stage 2, in a 65‑year‑old man, who presented with a sore throat and painful dysphagia. Computed tomography revealed an infiltrative heterogenous enhancing mass involving the left aryepiglottic fold. He underwent a tumor removal with frozen section for evaluating the surgical margin. Subsequent supraglottic laryngectomy was performed. Polymorphous low‑grade adenocarcinoma was diagnosed histologically, characterized by cytologic uniformly, morphologic diversity and an infiltrative growth pattern. Epiglottic cartilaginous invasion by the tumor is demonstrated. Clinical, radiological, endoscopic and pathological features with briefly reviewed relevant literatures are discussed. This is the first reported description in the literature, to the best of our knowledge, of an epiglottic polymorphous low‑grade adenocarcinoma receiving successful supraglottic laryngectomy with 7 year disease free survival.
