A Case of Spindle Cell Carcinoma Originating from the Maxillary Sinus / 대한이비인후과학회지

ABSTRACT

Spindle cell (sarcomatoid) carcinoma of the upper respiratory tract is a rare malignancy, and its diagnosis, treatment, and prognosis still remain controversial. Histopathologic examination of this uncommon tumor shows surface epithelialcarcinoma and an underlying spindle-shaped proliferation. In the head and neck region, it is found predominantly in the larynx and oral cavity. To our knowledge, spindle cell carcinoma of the paranasal sinus has been rarely reported. We report a 57-year-old woman with a spindle cell carcinoma originating from the maxillary sinus. She was treated with surgery and post operative radiotherapy. After 8 months of close follow-up, she shows no sign of recurrence or distant metastasis. We offer this case and a review of the related literature in an effort to increase awareness of this rare malignancy.
