Primary Combined Small-Cell and Squamous Cell Carcinoma of the Supraglottis: Case Report and Literature Review.
Combined small-cell carcinoma and squamous cell carcinoma of the larynx is an exquisitely rare and underreported primary tumor the head and neck region, with an English literature review revealing only 17 documented cases. There is limited information on how best to treat these patients oncologically, given the low number of reported cases. A subset of the reported cases also detail a unique local spread of this combined carcinoma, further obscuring the clinical picture of these patients. Here, we detail an 18th case, with nodal metastasis of only one component of the primary tumor, and discuss the published literature surrounding this etiology.
