Mesenchymal chondrosarcoma (MCS) was originally reported by Lichtenstein and Bernstein in 1959. A limited number of cases, however, has been reported to the present. Histological findings of several parts of this tumor are similar to those of the hemangiopericytoma (HP), reticulum cell sarcoma, and other small-cell tumors.<BR>The present report demonstrates a 23-year-old female with MCS of the left maxillary region. The histological diagnosis was considered to be HP based on the findings of a small biopsied specimen. Partial maxillectomy was performed under general anesthesia. The histological findings of the various parts of the resected tumor, however, provided a diagnosis that the tumor was MCS with similar histological features of HP in some parts.<BR>In this report, we have discussed the difference in clinical findings between MCS and HP.
