Background Chordomas are rare primary tumors of the bone that arise from embryonic notochord. They are locally aggressive tumors with a high tendency for postsurgical recurrence. On the other hand, distant metastases are rare. When they occur, they involve lungs, liver, lymph nodes, and bones. Skin and subcutaneous tissue involvement is even rarer and usually occurs by direct extension of the primary tumor or by local recurrence. Distant cutaneous metastasis from chordoma is an exceptional finding, with fewer than 20 cases reported in the literature. All the cutaneous metastases described derive from sacral chordomas, except for 2 cases in which the source of metastasis is skull-base chordomas. Case Description We report the case of a 55-year-old man with skin metastasis from a cervical chordoma. Conclusions Metastasis has to be taken into account in the differential diagnosis when a new skin lesion appears in a patient with a past medical history of chordoma. To the best of our knowledge, this is the first case of cutaneous metastasis from spinal cervical chordoma. A systematic literature review was performed.

Thoracic disk herniation (TDH) after traumatic injury is a relatively uncommon disease with few cases reported in the literature. Herniated disks in this location typically may result in progressive myelopathy and refractory pain. In the presence of these symptoms, surgical treatment may be indicated since spontaneous regression in this area is less common than that of disk herniations in the cervical or lumbar spine. Herein, we present the case of giant traumatic TDH that occurred at the T9–T10 level and spontaneously resolved after 5 months.We highlight the fact that regression of a herniated disk at the thoracic level may occur even in the absence of treatment. When considering this phenomenon, conservative management of these cases with clinical and radiological monitoring may be an appropriate first-line management for patients without signs of progressive myelopathy or severe refractory pain.

Osteoid osteoma is a benign osteoblastic tumor, quite uncommon in the spine. We report a case of an osteoid osteoma involving the atlas in a 6-year-old boy, who presented with suboccipital pain and torticollis. Initial radiological findings were ambiguous as magnetic resonance imaging showed mainly edema of upper cervical soft tissues. The subsequent computed tomography depicted a lesion of left lamina of C1. As conservative treatment failed, the lesion was surgically resected and the patient became pain free. To our knowledge, this is the first case of osteoid osteoma involving the atlas associated with abnormal soft tissue reaction reported in literature.

BACKGROUND Cranioplasty (CPL) is a surgical procedure that has still a high rate of complications, although it is commonly considered an easy and routine operation. In the literature, cranioplasty complications may rise up to 41% of cases, and the most frequently reported are infections, autologous bone flap resorption, and hematomas. Although possible, poor cosmetic results are rarely mentioned. METHODS We retrospectively analyzed the cases of 313 patients who underwent 377 surgical procedures for cranioplasty and reoperations for complications between 2008 and 2014. In other 2 patients we performed a new surgical procedure for the prosthesis fracture. Pediatric patients (aging from 5 to 17 years) have been included in this series in order to compare the complication rate between adult and pediatric populations. The clinical-radiological follow-up of these 313 patients lasted between 1 and 6 years. RESULTS Overall complications for cranioplasty were seen in 38 (12.14%) out of the 313 patients. However, complications requiring surgical therapy were seen in 28 patients who underwent 64 new surgical procedures. Adult male patients represented the majority of the group with cranioplasty complications. In the pediatric group we have not observed any complication requiring more than a clinical observation. Infections and autologous bone resorption were the most frequent complications reported in this series; however, we observed a poor cosmetic result as a concomitant but separate complication in more than 26% of our 313 patients. CONCLUSIONS In this paper we present an overview of all the possible complications of cranioplasty reported in the literature, comparing them with those observed in our series. We also discuss critically the most evident causes of complications, suggesting, when possible, solutions to avoid or limit them.
