“…Less common locations include the chest and abdominal wall, lung, fallopian tube, and other visceral organs. In the head and neck, extraskeletal chondromas are most prevalent in the tongue [3, 4] and rare in the cheek [6, 7], parotid gland [8, 9], neck [10], masticatory space [11], parapharyngeal space [12], and masseter muscle [13]. Our literature survey found only one previous account of a chondroma in the preauricular region [5].…”

An extraskeletal chondroma is a rare benign cartilaginous tumor that develops in soft tissue. Histologically, it is a lobulated nodule surrounded by a fibrous capsule; the inside consists of mature hyaline cartilage containing a few normal chondrocytes. We present a rare case of extraskeletal chondroma in the preauricular region. A 43-year-old man presented with a 2-cm-diameter right preauricular tumor that had been developing for 1 year. Magnetic resonance imaging showed a solid lobulated tumor in the right preauricular region, which was proximate to the capsule of the right temporomandibular joint (TMJ). This was subsequently resected under general anesthesia. The tumor was not in contact with the TMJ capsule and had not invaded the surrounding tissue, facilitating en bloc excision. Histopathologically, the tumor comprised mainly of hyaline cartilage containing chondrocytes with chondrocytic lacunae and was diagnosed as a chondroma. The postoperative period was uneventful, and there was no evidence of recurrence at the 2-year followup. We describe the clinical characteristics of our case and review the literature, emphasizing the differential diagnosis.

“…This tumor typically arises in the extremities but rarely is found in the neck, tongue, auricle, cheek, parotid gland, parapharyngeal space, and masticator space (81)(82)(83). It is thought that soft tissue chondroma develops from embryonal remnants ance with low to intermediate signal intensity on T1-weighted images, high signal intensity on T2-weighted images, and peripheral or septal contrast enhancement.…”

The World Health Organization (WHO) system for defining and classifying soft tissue tumors is usually applied to lesions that occur in the trunk and extremities, but it also provides an excellent framework for characterizing nonepithelial extraskeletal tumors of the head and neck. Although nonepithelial extraskeletal tumors are in the minority among head and neck lesions, they are by no means rare. The WHO classification system recognizes nine major types based on histologic differentiation: adipocytic, fibroblastic or myofibroblastic, fibrohistiocytic, smooth muscle, skeletal muscle, vascular, pericytic, and chondro-osseous tumors, as well as soft tissue tumors of uncertain differentiation. Tumors of each histologic type may be further subclassified on the basis of their biologic behavior as benign, intermediate (ie, having malignant potential), or malignant. Imaging plays an important role in the noninvasive diagnosis and characterization of nonepithelial soft tissue tumors of the head and neck, providing clues about tumor grade, composition, extent, and involvement of adjacent structures. Although the imaging characteristics of many such tumors are nonspecific, consideration of the clinical history in concert with the imaging findings may help limit the differential diagnosis or even allow reliable diagnosis of some of these tumors.

“…The etiology of soft tissue chondroma is uncertain. One theory is that these lesions develop from residual embryonal tissue in an area of pre‐existing fetal cartilage, the other is that pluripotential mesenchymal cells undergo metaplasia, differentiating into cartilage as a result of some irritating stimulus (7, 10).…”

Soft tissue chondromas are rare benign tumors unrelated to bone that arise primarily in the distal extremities, especially in the fingers of middle-aged adults. We report an extremely rare case of congenital soft tissue chondroma, arising in the left great toe of a new-born infant. The present case is, to our knowledge, the first to be described in the dermatologic literature and the second reported case of congenital soft tissue chondroma.
