 Malignant neoplasms, showing simultaneous presence of epithelial and nonepithelial elements are rare and these tumors are called as true carcinosarcoma, pseudeosarcoma or spindle cell squamous carcinoma according to the origins of sarcomatous component.

 This report describes the histological characteristics of spindle cell squamous carcinoma of the maxillary sinus as follows: 1) This tumor was mainly composed of anaplastic spindle cells. 2) Some epithelial cell clusters were observed at the peripheral portions. 3) Transitions from squamous to spindle-shaped cells were observed.

 These findings suggest that spindle cells of this tumor are epithelial in ther origin, and they reveals their own malignant potential.
