A Case of Auricular Chondroma

Abstract

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 walling the temporomandibular joint: Report of a rare case and review of the literature

“…Within the head and neck area the tongue is primarily affected [ 5 ]. Extraskeletal chondroma has also been described within the buccal mucosa, the cheeks, the parotid glands, the nasal cavity, the paranasal sinuses, the larynx, the parapharyngeal space, the tonsils, the auricle, the soft and hard palate, the masticatory space, the masseter muscle, the dura mater and the scalp [ 3 , [6] , [7] , [8] , [9] , [10] ]. Only one other case of extraskeletal chondroma has been reported in the preauricular region so far [ 4 ].…”

“…The treatment of extraskeletal chondroma involves complete resection, including removal of the fibrous capsule. Recurrence rates of 10%–15% are reported [ 7 , 8 ]. In these cases, a second resection is recommended [ 6 ].…”

Formation of metal interconnects and their resistance-change behavior during tensile stretching for stretchable packaging applications

“…Recently wearable devices as well as IoT technology have been extensively developed and commercialized as innovative driving forces to replace the smartphone business for unremmiting growth of ICT industy [1][2][3][4][5][6][7][8][9][10][11]. For many wearable devices such as smart skin patch systems and healthcare monitoring systems, considerable degree of stretchability as well as flexibility is necessary for their proper operation [1][2][3][4][5][6][7][8][9][10][11][12].…”

“…In addition to easy thickness control of a PDMS substrate with simple spin coating process, it is also chemically inert and stable at high temperature [1,2,13,[16][17][18][19]. However, metal films deposited as interconnects on a PDMS substrate easily crack due to the thermal expansion mismatch between metals and PDMS even before stretching of a PDMS substrate.…”
