Chondroma (benign)
Overview
A chondroma is a benign cartilaginous tumor, which is encapsulated with a lobular growing pattern. Tumor cells (chondrocytes, cartilaginous cells) resemble normal cells and produce the cartilaginous matrix (amorphous, basophilic material). Characteristic features of this tumor include the vascular axes within the tumor, which make the distinction with normal hyaline cartilage.
Symptoms
A chondroma is a benign cartilaginous neoplasm neoplasm or tumor, tissue composed of cells that grow in an abnormal way. Normal tissue is growth-limited, i.e., cell reproduction is equal to cell death. ..... Click the link for more information.. Cartilaginous tumors make up the second-largest group of bone neoplasms. They are rare in the head and neck region; most lesions are found in the long bones, pelvis, and ribs. (1) When they do arise in the head and neck, the sites of predilection are the maxillofacial region, the larynx, and the nasal septum.
Causes
Enchondroma protuberans is a rare tumour that rises from an intramedullary enchondroma with an exophytic growth pattern. Although it causes an interesting clinical picture it is benign, and marginal resection of the tumour with bone grafting of the intramedullary defect is curative
