Extraskeletal chondroma in the auricle.

Extraskeletal chondroma is a rare benign tumor that develops in soft tissues, and histologically, it is a lobulated nodule surrounded by a fibrous capsule, and the inside consists of mature cartilage cells and diffuse hyalinized matrix. It occurs preferentially in the hand and foot area of adults, and the development in the head and neck area is very rare. We had a very rare case of extraskeletal chondroma that developed in the auricle and report the case together with a review of the literature.
