Abstract
|
|
|
Chondroblastoma is a rare benign bone tumor most frequently found in the epiphyseal region of long bones. The most common locations are the knee and proximal humerus, but the rib is an unusual site. Second decade is the most common age group.
The ossification centers for the rib appear in the second fetal month and ossify in a caudal-tocranial direction. There are also epiphyseal centers at the head and tubercle of the rib that appear at puberty and ossify in the third decade. The
epiphyseal
plates of the head and tubercle may be the site of origin of posterior chondroblastomas; the anterior lesions may arise from the costochondral junction.
The histologic features consist of polygonal chodroblast, small foci of chondroid production, osteoclast-like giant cell, and are diagnostic of chondroblastoma.
We experienced a case of the chondroblastoma arising from the rib, and its clinical and histologic features were discussed. (Korean J Thoracic Cardiovas Surg 1994; 27:494-6)
