摘要:
&NA;Conventional squamous cell carcinoma (SCC) of the larynx presents as a largely flat or ulcerated lesion and is usually categorized histologically asin situ, superficially invasive, or deeply invasive. Papillary and exophytic squamous cell carcinomas of the larynx represent uncommon but distinct subtypes of SCC. As implied by their designations, these tumor types show predominant papillary or exophytic growth in the form of finger‐like or filiform and broad‐based bulbous fronds, respectively. Both tumor types are composed of cytologically malignant squamous epithelium. The following case illustrates the clinical and pathologic features of papillary squamous cell carcinoma and emphasizes the importance of distinguishing this entity from conventional squamous cell carcinoma of the larynx.
