Primary combined small cell carcinoma of the larynx.
The clinical and pathologic findings of six cases of combined small cell carcinoma of the larynx are described. This tumor is a subtype of small cell carcinoma in which there is a definite component of oat cell carcinoma (or intermediate cell type carcinoma) together with squamous cell carcinoma or adenocarcinoma or both. The neoplasm seems to derive from a common cell with subsequent divergent differentiation into the Kulchitsky cells, squamous cells, and/or glandular cells. After histologic diagnosis, adequate evaluation for tumor staging is mandatory. Like pulmonary combined small cell carcinoma, this neoplasm may be best treated with systemic chemotherapy and radiotherapy. The prognosis is similar to that of other subtypes of small cell carcinoma of the larynx.
