Cartilaginous choristoma of bony external auditory canal is very rare. Appearing as a horny sha-ped hard mass, cartilaginous choristoma can be found in the medial portion of anterior wall of external auditory canal. Histologically, it consists of adult-type hyaline cartilage without neoplastic features. If cartilaginous choristoma shows growing tendency or ear symptoms, surgical excision would be the treatment of choice. Here, we report a case of cartilaginous choristoma that occurred in the external auditory canal in an 8-year-old boy.

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.

BACKGROUND: To construct a sophisticated three-dimensional framework, numerous modifications have been reported in the literature. However, most surgeons have paid little attention to the anatomical configuration of the concha and more to its deepness and hollowness, leading to unsatisfactory outcomes. METHODS: For a configuration of the concha that is definitely anatomical, the author further developed and employed the conchal bowl element, which has been used by several surgeons although the results have not been published elsewhere. The author constructed the conchal bowl element in one of three patterns according to the amount of available cartilages: one block, two-pieces, or a cymba bowl element only. A total of 20 patients underwent auricular reconstruction using a costal cartilage framework between 2009 and 2012. The 8 earliest reconstructions were performed without a conchal bowl element and the latter 12 with a conchal bowl element. The patients were followed up for more than 1 year. The aesthetic results were scored by evaluating characteristics involving the stability of the crus helicis, the conchal definition, and the smoothness of the helical curve. RESULTS: The ears reconstructed early without a conchal bowl element showed a shallow and one or two incompletely separated concha with an obliterated cymba conchal space. They also did not have a realistic or smooth curve of the helix because of an unstable crus helicis. However, ears reconstructed later with the concha bowl element showed a definite crus helicis, deep cymba conchal space, and smooth helical curve. CONCLUSIONS: The construction of the conchal bowl element is simple, not time-consuming procedure. It is suggested that the conchal bowl element must be constructed and attached to the main framework for natural configuration of the reconstructed ear.

While many treatments have been performed to repair the chondral defects during last two decades, most of the repaired tissue has shown fibrocartilage or hyaline-like cartilage. Therefore, the clinical outcomes of conventional treatments are unrealiable and unpredictable. Cell-based treatments have recently emerged to regenerate the cartilage with better biomechanical properties and histological quality so that it resembles nature hyaline cartilage. This review discusses the current methodology of the cell-based treatments and their clinical outcomes.

OBJECTIVES: This study aimed to measure the dimensions of the nasal septal cartilage in adult Filipino Malay cadavers and calculate the cartilage area as well as the amount of graft material that can be harvested from the septal cartilage.

METHODS:
Design: Descriptive, cross-sectional
Setting: Pamantasan ng Lungsod ng Maynila College of Medicine Anatomy Laboratory
Subjects: Ten preserved adult cadavers dissected within a period from September 2010 to October 2010. The septal cartilages were harvested and the lengths of the cephalic margin, dorsal margin, caudal margin and ventral margin were measured. From these measurements, the total area of the cartilage and the amount of graft material that can be harvested were calculated.

RESULTS: The mean length of each margin of the septal cartilage was 25.9mm (cephalic edge), 22.3 mm (dorsal edge), 21.4mm (caudal edge) and 33.1 mm (ventral edge). The area of the septal cartilage had a mean value of 652.5 mm². The amount of septal cartilage which can be harvested had a mean area of 403mm².

CONCLUSION: This study showed a slight decrease in septal cartilage area to 652.5 mm² and in available graft material to 403 mm². While this decrease may reflect the apparently smaller noses of native Southeast Asians compared to East Asians and South Asians, the difference in values can also be due to the difference in the number of subjects or in methods of measurement and further studies are recommended to determine the extent of inter-racial variability.

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 chondroma is a benign bone tumor composed of mature hyaline cartilage which is slow growing and relatively rare. Most of the chonroma are found in the hand and foot, chiefly in the phalanges but is rare in the spine. We are reporting a case with severe radicular pain of the right arm and right paravertebral muscular atrophy in the cervical region.

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.

Extraskeletal chondromas are benign soft tissue tumor of hyaline cartilage. These tumors are rare and the pathogenesis is unclear. They are usually involves the hand or feet. We report the case of extraskeletal chondroma arising from subungual region of the finger with nail deformity and review of the literature.
