A Case of Auricular Chondroma

Extraskeletal chondroma is a rare benign tumor that develops in the soft tissues, and it manifests as a solitary subcutaneous nodule or a slowly growing tumor. It occurs preferentially in the hand and foot area of adults, and the development in the auricle is very rare. We report a rare case of chondroma that developed in the auricle, which were treated with wedge excision and reconstructed using a Burow's triangle, with a review of the literature.

Extraskeletal Chondroma of Finger in a Young Woman: A Case Report / 대한골관절종양학회지

Extraskeletal chondroma is a benign soft tissue tumor which is composed of hyaline cartilage but arises from the fibrous stroma rather than from mature cartilaginous or osseous tissue. Extraskeletal chondroma is relatively rare and occurs most frequently in the soft tissue around the joints of hands and feet. We present one case of extraskeletal chondroma in a finger of a young woman.

Subungual Extraskeletal Chondroma / 대한피부과학회지

Extraskeletal chondroma is a relatively uncommon, benign soft tissue tumor that usually occurs adjacent to the periarticular tissues or tenosynovium, without any adhesion to the underlying bone. The most common site of occurrence is the hands, with more than 60% of all extraskeletal chondromas being located here. Histologically, it can resemble hyaline cartilage or chondrosarcoma of bone, which is more cellular. Whatever the histologic appearance is, the behavior is uniformly benign and it does not metastasize, therefore the recommended treatment is local excision. We report here on a case of subungual extraskeletal chondroma in a 22-year-old female who presented with a subungual nodule of the left big toe.

A Case of Extraskeletal Chondroma of the Face / 대한피부과학회지

Extraskeletal chondroma is a relatively-uncommon, benign, cartilagenous tumor of the soft tissue unrelated to bone. It occurs most frequently in the hands and feet of adults in the fourth and fifth decades and presents as a solitary, painless, slowly-growing mass usually measuring <3 cm in diameter. Histologically, it can resemble hyaline cartilage or chondrosarcoma of bone, which is more cellular. Whatever the histologic appearance is, the behavior is uniformly-benign and it does not metastasize so the recommended treatment is local excision. We report a rare case of extraskeletal chondromas in a 30 year-old female who presented with a skin-colored, hard and movable nodule on her right cheek.

A Case of Extraskeletal Chondroma of the Foot / 대한피부과학회지

Among various soft tissue tumors, extraskeletal chondroma is a rare benign cartilaginous tumor most frequently found in the hands, adjacent to periarticular tissue. We recently experienced a case of extraskeletal chondroma in a 47-year-old woman. The skin lesion showed a slowly-growing, solitary nodule on the dorsal aspect of her foot, causing pain and tenderness. An excisional biopsy was undertaken, revealing a well-encapsulated subcutaneous nodule which was mainly composed of mature hyaline cartilage.

A Case of Extraskeletal Chondroma of External Auditory Canal / 대한이비인후과학회지

Chondroma is a relatively common tumor that occurs in any areas of the body and is characterized by the formation of abundant hyaline cartilage. However, benign extraosseous cartilaginous lesions are uncommon and extraskeletal chondroma of the bony external auditory canal (EAC) is extremely rare. We recently experienced a case of extraskeletal chondroma of the bony EAC in a young female who was treated with simple excision. This case is reported along with a brief review of the literature.
