Nasal chondromesenchymal hamartoma in infancy:report of a case with review of the literature

Objective To report a rare case of chondromesenchymal hamartoma in nasal cavity. Methods The tissue sections of the tumor were stained by HE method and observed with a microscope. Results Histologically, the tumor was characterized by a mixture of various mesenchymal elements, including spindle cells, collagen fibers, and irregular islands of osseous and chon-droid tissues. The pathologic mitosis was rarely seen in the tumor cells. Conclusion This tumor has a benign biological behav-ior, and complete resection is the treatment of choice. It is apt to be misdiagnosed as mesenchymal chondrosacoma.
