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.

Endobronchial chondroma is a cartilaginous benign tumor, which arises from bronchial cartilage. As a rare benign tumor, endobronchial chondroma differs from cartilaginous hamartoma in that it includes cartilage components only, but hamartoma contains lipomatous and lymphoid tissue. The clinical manifestations of endobronchial chondroma are associated with the extent of mechanical obstruction of bronchus. Symptoms of endobronchial chondroma are nonspecific, such as cough, sputum, fever, or dyspnea on exertion. Endobronchial chondroma is often misdiagnosed as other diseases, such as asthma, chronic obstructive pulmonary disease, or pulmonary tuberculosis. The treatment is usually surgical procedures, such as resection of lung segment or lobe by thoracostomy, or resection of tumor by bronchoscopy. We report a case of the patient who was diagnosed to have endobronchial chondroma treated by bronchial resection and end to end anastomosis.

Soft-tissue chondroma was very rare in incidence and thought to be benign. Recently, we operated upon a 13 year-old female with a chondroma of the middle mediastinum, which was incidentally detected in chest X-ray as mediastinal mass, measured about 10x8x7 cm in size and completely resected via thoracotomy.

Intracapsular and paraarticular chondroma is a rare benign lesion of the large joints (mostly the knee). We report a case of intracapsular and paraarticular chondroma in the infrapatellar Hoffa’s fat pad that presented as a painful palpable mass in 15-year-old woman. A physical examination revealed a firm, movable and tender mass in the infrapatellar area. Magnetic resonance images showed an ovoid, well-defined, soft tissue mass with focal calcification in the infrapatellar fat pad. The final pathology revealed an intracapsular and paraarticular chondroma.

Periosteal chondroma is a rare, slow-growing, benign cartilaginous tumor that develops between the periosteum and cortex, but there are no reports of multiple periosteal chondroma of the toes. A 19-year-old male presented with a palpable mass of the right fourth toe with tenderness for one year. A radiology examination revealed multiple, radio-lucent lesions with mild cortical irregularity. The magnetic resonance imaging findings were chondrogenic tumors with multiple, well-defined T1-low and T2-high signal enhanced lesions involved in the fourth proximal, middle, and distal phalanges. The tumors were removed by a surgical resection and curettage. Histologically, the tumors were proven to be periosteal chondroma.

Maffucci's syndrome is generally characterized by chondromatosis with vascular lesions of mesodermal origin, however, intracranial chondroma is rare. We present a case of Maffucci syndrome with paracellar chondroma and the review of literatures.

Purpose: Soft tissue chondroma is a rare benign tumor, found mainly on the palm and sole and grows slowly. Typically, mature hyaline cartilage is the dominant pathological feature. There are reports that assert soft tissue chondromas to be a cause of median nerve entrapment syndrome. However, this is the first case report showing soft tissue chondroma to be a cause of simultaneous median and ulnar neuropathy. Methods: A 62 year-old woman presented with chief complaints of numbness and hypoesthesia of her right palm for 4 to 5 years, and a palpable mass on her right palm that had been increasing in size slowly for 3 years. Physical examination revealed a firm, mobile, non-tender and about $3{\times}3\;cm^2$ sized mass in the center of the right palm. Electromyography showed entrapment neuropathy of the median and ulnar nerve. Ultrasonography showed an approximately $5.7\;cm^2$ mass below the flexor tendon of ring finger. Upon surgical excision, a $3{\times}3\;cm^2$ mass attached to the flexor digitorum profundus of ring finger and redness and hypertrophy of both the median and ulnar nerve were discovered. Mass excision was performed gently and the specimen was referred for histopathologic study. Mass excision resulted in median and ulnar nerve release. Results: The pathology report confirmed the mass to be a soft tissue chondroma with mature hyaline cartilage. The patient exhibited post-operative improvement of her symptoms and did not show any complications. Conclusion: This is the first case report showing soft tissue chondroma to be a cause of simultaneous median and ulnar neuropathy.

These cases of Chondroma of the Temporo-madibular region and ChondroSarcoma of the mandibular retromolar areawhich are presented because of its comparative rarity. Its offen difficult to differentiate between Chondroma and Chondro-Sarcoma, by clinically by Roentgenogram, but in this Case revealed typical Sarcemd Sign by microscopically. No observed recurrence after 6 months fall ming excision.

Extra-skeletal chondroma, characterized by its lack of connection with the adjacent bone, includes synovial chondromatosis, intra-articular and para-articular chondroma, and soft tissue chondroma. Among them, the last two lesions are extremely rare. This is the case about 20-year-old soldier, who had complained of tenderness of the knee, pain and fullness during knee flexion and limitation of motion after a hard military training. We found a mass in the x-ray and MRI and resect the mass surgically, which was a $5.5{\times}4{\times}3$ cm size hard solitary mass. On microscopic finding, it was consisted of lobulated hyaline cartilage and outer fibrous capsule, and we ascertained it as para-articular chondroma. We experienced a case of para-articular chondroma in the infrapatellar fat pad of the knee joint and present its clinical, radiologic and pathologic findings with literature review.

Periosteal chondroma is a slow growing benign chondroid tumor. It erode the surface of cortex and induce a saucer shape defect. Histologically, it occasionally show hypercellularity, mitosis which can lead to the erroneous diagnosis of malignant tumor. Clinical, radiographic and pathological investigations are necessary to establish the diagnosis. Marginal excision proved an effective treatment. To our knowledge, this benign chondroid tumor of humerus has never been previously reported in Korea. We report a case of periosteal chondroma of proximal humerus mimicking periosteal chondrosarcoma.
