Four Cases of Pseudosarcomatous Carcinoma of the Larynx / 대한이비인후과학회지

ABSTRACT

Pseudosarcomatous carcinoma is a kind of squamous cell carcinoma having biphasic pattern, with both squamous and spindle cell components. Pseudosarcomatous carcinoma of head and neck mucosa is a very rare high-grade malignancy that may cause diagnostic and therapeutic controversies. The tools used for diagnosing pseudosarcomatous carcinoma are histopathological analysis and immunohistochemical analysis. We experienced four cases, a 60-year-old male patient with pseudosarcomatous carcinoma located at the left false vocal fold, a 68-year-old female patient with the same carcinoma located at both false vocal folds, 73-year-old male patient with the same carcinoma at the epiglottis, and a 69-year-old male patient with the same carcinoma at the left true vocal fold. We report these four cases with a brief review of literatures.
