Chordomas are rare malignant primary bone tumors, which most often occur in the sacral area. These tumors uncommonly affect the skin, and may not be recognized by dermatologists. We present a case of an adult woman with cutaneous metastasis of a primary sacral chordoma.

Chordomas constitute between 1% and 4% of primary malignant bone tumors. Approximately 50% originate in the sacrum, 35% at the base of the skull, and 15% in the true vertebrae. The majority of tumors are encountered from the fifth through seventh decades, with a male preponderance.

The clinical and radiological features of 44 cranial chordomas are recorded. Classical features of a mid-line partially calcified tumour, destroying the clivus and causing a soft tissue mass in the sphenoid sinus or nasopharynx were present in about half of the cases. The high incidence of unilateral bone erosion which occurred in nearly a third of the

All patients with chordomas that have been treated in the Dundee neurosurgical unit are reviewed. Five intracranial and two sacral chordomas have presented since the unit opened in 1966. Survival has ranged from one to fifteen years following treatment.

SUMMARY Three cases of clival chordomas are reviewed and the findings are compared to those in the recent literature. In the first case the tumour arose from the basion, spreading downwards to invade the upper cervical canal and the paravertebral fascial planes. The second case is a rare case since it affects a 12 year old pre‐adolescent boy. The third

✓ A series of 54 patients with spinal chordomas were treated at Memorial Sloan-Kettering Cancer Center between 1949 and 1976. Thirty-six lesions were located in the sacrococcygeal region and 18 involved the vertebral column at a higher level. The male to female ratio was 35:19. Vertebral chordomas generally occurred in a younger age group.

Ultrastructural Pathology, 1987
We reject the notion that the concept of "chondroid chordoma" be abandoned in favor of an interpretation of the cartilaginous origin of these lesions. We have demonstrated by electron microscopic and immunohistochemical means that these neoplasms can exhibit distinctly epithelial characteristics in their chondroid as well as their epithelial areas. The

In a 20 year period seven cases of craniocervical chordoma were seen and treated. Since it is not possible to completely resect these lesions, the aim of treatment has been to debulk the tumor as much as feasible and employ postoperative irridation. Palliation is the most that can be hoped for, and minimal success in delaying the natural history of the

We report a case of an 85-year-old white man with a diffuse form of psoriasis, who showed a large asymptomatic subcutaneous tumour in the sacrococcygeal region. On cut section there was a subcutaneous neoplasia with a glistening, friable surface. Histologically, the deep dermis was infiltrated by cords and nests of pleomorphic cells embedded in an ...
