유척삭종(parachordoma)은 팔, 다리, 가슴에 주로 발생하며 천천히 자라는 저등급 악성 종양으로 알려져 있다. 대표적인 감별진단으로는 척삭종(chordoma), 뼈외 점액양 연골육종(extraskeletal myxoid chondrosarcoma) 등이 있으며, 조직학적 검사와 함께 면역조직화학적 검사가 감별진단에 도움이 된다. 저자는 우측 흉벽에 발생한 유척삭종을 광범위 절제 및 흉벽 재건술 후 16개월 동안 재발없이 추적 관찰한 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다.

Chondrosarcomas are uncommon tumors. Approximately 5-10% are located in the head and neck. Nasal septal chondrosarcoma is exceedingly rare, with an extensive review of the world literature revealing only 50 reported cases. Most occur in middle-aged man. Surgical resection is the definitive treatment of choice. Radiation and chemotherapy are reserved for residual or recurrent diseases and palliation. We present a case of nasal septal chondrosarcoma treated with craniofacial resection and postoperative radiation therapy.

Mesenchymal chondrosarcoma is a rare malignant tumor of bone and soft tissue. This aggressive form of chondrosarcoma represents only 3% to 9% of all chondrosarcomas. This neoplasm is characterized by sheets or clusters of undifferentiated spindle or round cells surrounding discrete nodules of well-differentiated cartilage. We experienced a case of mesenchymal chondrosarcoma on mandibular body. Two years ago, the patient had been treated the intrabony cystic lesion on mandiblular left body. At that time, cartilage portion was not detected in the cystic specimen. Two years after cyst enucleation, the recurred large neoplasm in the mandibular left body was noted, and it was diagnosed as 4.5 cm sized mesenchymal chondrosarcoma. The mandibular tumor was widely resected and rigid-plate and cervical musculocutaneous flap were used for reconstruction of resected bone and soft tissues. No complications and recurrence were noted for 6 months postoperatively.

간엽성 연골육종은 전형적인 연골육종과는 달리 매우 드문 것으로 알려져 있으며, 골격계 부위에서는 하지, 특히 대퇴골에서 대부분 발생하며, 다음으로 두안면부, 골반부에서 발생하는 것으로 보고되어 왔다. 11세 남아가 좌측 후족부 통증으로 타 병원에서 양성 골 종양 추정 하에 수술적 제거술을 시행 받고, 수술 후 조직검사 결과, 악성 종양으로 진단되어, 본원으로 전원 되었다. 조직 재 판독 결과, 좌측 종골 간엽성 연골 육종으로 진단되어, 슬하부 절단을 시행하였다. 외래 경과 관찰 중 술 후 3개월에 흉부 컴퓨터 촬영상 다발성 폐 전이성 결절 소견 보여 전이절제술 및 항암 치료를 시행하였다. 문헌상 간엽성 연골육종이 족저부 연부 조직에 발생한 경우는 1예가 있으나 종골 골조직에 발생한 경우는 없어 문헌 고찰과 함께 보고하는 바이다.

Multicentric chondrosarcoma other than the mesenchymal subtype is rare separate entity. We experienced a case with nonmonomelic synchronous multicentric chondrosarcoma without any preexisting lesions of Oilier's disease or Maffucci's syndrome. To our knowledge, there was no report of synchronous nonmonomelic multicentric chondrosarcoma. A thirty-three year old man had right distal thigh pain of one and half year. Bone scan showed hot lesions on medial condyle of right femur and shaft of left femur. Plain X-ray showed osteolytic lesion on right femur and slight cortical thickening and calcific lesion was observed on left femoral shaft. Curettage and bone cement filling was done on both lesions. The pathology reports were grade I chondrosarcoma on both side of femur. At one month from operation, pathologic fracture of left femur occurred on bone cement-host bone junction. Conservative treatment and radiotherapy of 60Gy was done. At 8 months from operation, nonunion was evident. Segmental resection of left femur with contralateral fibula graft and second look operation on right condyle lesion were done. At 6 months from revision, fracture occurred at host-graft bone junction. We removed previous hardware and applied long DCP and massive autogenous bone graft. Afterwards, the patient looks good and union was progressing. But at 4 years from last operation, hypertrophic nonunion occurred. Another revision was done with condylar plate and bone graft and now he is well without any sign of local recurrence or metastasis.

Intracranial extraskeletal myxoid chondrosarcoma is extremely rare, with only seven patients previously reported. We present a case report of a 21-year-old woman admitted for weakness in her right extremities and symptoms of increased intracranial pressure. Magnetic resonance imaging (MRI) revealed hydrocephalus and a well-enhanced large mass around her left thalamus. A left parietal craniotomy and a cortisectomy at the superior parietal lobule were performed. Total surgical resection was also performed, and pathology results confirmed an extraskeletal myxoid chondrosarcoma. Postoperative MRI showed no residual tumor, and the patient underwent radiotherapy. After six months of radiotherapy, the patient's headache and weakness had improved to grade IV. This malignant tumor showed high rates of recurrence in previous reports. We here report another occurrence of this highly malignant and rare tumor in a patient treated using total surgical excision and adjuvant radiotherapy.

We report large tumors of the left thoracic cavity, which arose from the ribs, were diagnosed as chondrosarcoma in a 4-year-old male mixed dog. The dog was presented with swelling in the left side of the chest wall and lameness. The masses were found to be circumscribed, whitish-grey, large and firm. The cut surface revealed whitish-grey lobules of varying size with cartilaginous consistency. Those were subsequently metastasized to the lung and mandibular lymph node. Histologically, the tumors were made up of clusters of chondroid cells having pleomorphic hyperchromatic nuclei with occasional mitosis. A special and immunohistochemical staining was performed to confirm the diagnosis. Chondroid matrix in tumor showed a positive reaction for alcian blue-periodic acid-Schiff staining. Immunoreactivity to S-100 proteins was present in the cytoplasm and/or nucleus of chondrocytes in tumor. The final diagnosis was grade III chondrosarcoma in the rib, considering histological features in grading criteria.

An 8-year-old, spayed female Persian cat weighing 3.6 kg presented with a lumbosacral mass and bilateral weight bearing hindlimb lameness. Computed tomography (CT) and magnetic resonance imaging (MRI) revealed a dumbbell-shaped heterogeneous mass extending through the internal surface of the ileum and surrounding the lumbosacral junction. CT also revealed extensive osteoproliferation and bone lysis of the sacrum, but no evidence of any pulmonary metastasis. Furthermore, MRI revealed a focal area in the spinal cord showing connection with the adjacent tumor, suggesting tumor invasion into the spinal cord. Low-grade myxoid chondrosarcoma was histopathologically diagnosed. This is the first report describing CT and MRI findings of spinal cord chondrosarcoma in veterinary medicine. This study suggests that combining CT with MRI is a more sensitive tool for evaluating spinal tumors than using CT or MRI alone.

연골 육종은 가장 흔한 원발성 골육종 중 하나로, 간엽성 연골육종을 제외하면 대체로 저 악성도 병변이며, 다발성 발현이나 원격 전이가 드문 것으로 알려져 있다. 다발성 내연골종(Ollier's disease)과 Maffucci's 증후군에서 다발성 연골육종이 발생한 례가 드물게 보고되었으며, 아직까지 한 관절을 사이에 두고 그 근위부와 원위부에서 연골육종이 동시에 발생한 례는 보고된 적이 없었다. 저자들은 30세 남자 환자에서 폐나 내장의 전이를 동반하지 않고, 한쪽 견관절을 사이에 두고 견갑골의 견봉과 상완골에서 동시에 발생한 다발성 연골육종을 경험하였으며, 이를 "동시성 다발성 관절 근접 연골육종"이라 명하였다. 견봉에 위치한 병변은 소파술과 함께 동종 골이식과 시멘트 충전술을 시행하였으며, 근위 상완골 병변은 설상 절제술과 시멘트 충전술을 시행하였다. 수술 후 18개월까지 재발의 증거가 관찰되지 않았으며, 통증 없이 전 범위 운동이 가능하였다.
