Abstract
Extraskeletal chondroma is a benign cartilaginous tumor that occurs predominantly in the soft tissues near small joints of the hands and feet. There are rare reports of the lesion in other sites, such as the head, neck, trunk, oral cavity, larynx, and pharynx. We present a case of an axillary mass in a 15-year-old girl who underwent MRI examination and resection, with the ultimate diagnosis of an extraskeletal chondroma, in order to expand the differential diagnosis of an axillary soft tissue mass in an adolescent.

Extraskeletal chondroma, referred to as chondroma of soft parts [1], is a benign soft tissue tumor composed mainly of hyaline cartilage with no connection to bone or periosteum
Extraskeletal chondroma is a lesion that can be found at any age, but it usually occurs in adults and is very rare in children, with only a few case reports in the literature [4,5,6,7,8]
We present a case of an axillary mass in a 15-yearold girl who underwent magnetic resonance imaging (MRI) examination and resection, with the ultimate diagnosis of an extraskeletal chondroma, in order to expand the differential diagnosis of an axillary soft tissue mass in an adolescent
Summary
Extraskeletal chondroma, referred to as chondroma of soft parts [1], is a benign soft tissue tumor composed mainly of hyaline cartilage with no connection to bone or periosteum. It is usually small, measuring less than 3 cm in diameter and of similar histology to a juxtacortical or periosteal chondroma, which is located between the bone and periosteum. The most frequent sites of involvement for an extraskeletal chondroma are the hands and feet [2]. We present a case of an axillary mass in a 15-yearold girl who underwent magnetic resonance imaging (MRI) examination and resection, with the ultimate diagnosis of an extraskeletal chondroma, in order to expand the differential diagnosis of an axillary soft tissue mass in an adolescent
