Arthroscopic Removal

We report a case of a subperiosteal osteoid osteoma on the talar neck that was removed arthroscopically. Intralesional excision, en bloc resection, and percutaneous ablation techniques have all been used for the treatment of osteoid osteoma. For intra-articular osteoid osteomas, arthroscopy-assisted removal of the tumor has been described in a few case reports. Obtaining a nidus fragment for pathologic evaluation is important during arthroscopic removal of intra-articular osteoid osteomas. Sometimes it is not possible to obtain a specimen for pathologic examination. In the present case, the osteoid osteoma on the talar neck was easily located, the nidus was completely removed, and the tumor was extirpated. (J Am Podiatr Med Assoc 97(3): 238–243, 2007)

Pathologic Evaluation

Endoscopic laser resection of early laryngeal carcinoma is an increasingly used treatment modality; however, the limited exposure achieved and the alteration of vocal function are still major problems. A new surgical procedure, “window” laryngoplasty, has been devised and tested in an in vivo study in 6 canines with 50 days' survival. The right vocal cord was incised endoscopically with the carbon dioxide laser, and the en bloc specimen with adjacent thyroid cartilage was removed through a window approach made in the thyroid cartilage. A sternohyoid muscle flap based superiorly was inserted into the cartilaginous window to reconstruct a pseudocord with coverage of either mucosa or fascia. A diode laser soldering technique was used to secure the mucosal graft in place. Epithelial transplantation can be accomplished externally with precise endoscopic guidance for reliable placement of the pseudocord. The results show that the new technique, a combination of endoscopic and open approaches, may be a better treatment choice than standard vertical partial laryngectomy in selected patients. Advantages of this technique include adequate en bloc resection, including adjacent cartilage for pathologic evaluation, preservation of the integrity of most of the laryngeal framework, avoidance of tracheotomy, and better functional results.

Disease Free

En bloc resection of chordoma has been shown to be critical for prolonging long-term survival and disease-free intervals in patients. Cervical spine chordomas pose special challenges because of the vertebral arteries and critical nerve roots involved. Multilevel chordomas pose even greater challenges because of the need to remove multiple segments of the spine in 1 piece without tumor violation. Although there have been 2 case reports describing multilevel spondylectomy for cervical chordoma, to the authors' knowledge, there are no reports of parasagittal osteotomies for en bloc resection of multilevel cervical chordomas. The use of these osteotomies allows us to avoid intralesional resection and adhere to the oncological principle of en bloc tumor excision. The authors report their management of 3 multilevel cervical chordomas and describe their technique of en bloc tumor removal using parasagittal osteotomy.

High Index Of Suspicion

This article describes two cases of juxta-articular osteoid osteoma of talar neck. Both patients were initially treated as having ankle sprains or arthritis before diagnosis of osteoid osteoma. A high index of suspicion and appropriate imaging studies are important to make an early diagnosis of this disorder. Once diagnosis is confirmed, en bloc resection and autogenous bone graft can cure the disorder.

Primary spinal chondrosarcoma (CS) is rare. Only a few previous case reports have included a detailed description of the surgical process used to treat the CS. In addition, a paucity of documentation exists comparing differences in the outcomes between the approaches in en bloc resection. Here, we present a case of CS in the lumbar (L) spine treated with two-stage (anterior and posterior approach) en bloc surgery and analyze the differences between one-stage and two-stage approaches in the treatment of primary lumbar CS. A 30-year-old male patient with an L3 vertebral body CS presented with back pain and lower limb weakness. Lumbar spine magnetic resonance imaging (MRI) showed an L3 vertebral body tumor with cord and root compression. Two-stage surgery comprising posterior total laminectomy and transpedicular screw fixation over L2–L4 in the first stage, with subsequent anterior corpectomy, cage implantation, and anterior lumbar interbody fusion was performed to achieve total tumor removal and stabilization. The patient’s symptoms improved postoperatively, with no recurrence as of the 2-year follow-up. The analysis of previous similar cases showed that two-stage surgery, compared with one-stage surgery, appears to be beneficial in lumbar spine multisegment disease, providing a lower recurrence rate.

Central Mucoepidermoid Carcinoma

The cornerstone modality of treatment of central mucoepidermoid carcinoma (CMEC) of the mandible is surgery, optimally, an en bloc resection with/without segmental or hemimandibulectomy. Notwithstanding the documentation of a survival benefit in few case reports with the addition of postoperative radiotherapy in carefully selected high-risk patients, there does not exist a clearly defined consensus regarding the role of adjuvant radiotherapy. We report the case of a 49-year-old man who presented with right lower jaw swelling which on imaging was found to be a multiloculated lesion causing bony expansion and cortical destruction of the mandible and was diagnosed with CMEC after radiological and histopathological criteria were met. He underwent right hemimandibulectomy and histopathology showed squamous and mucinous cells with positive mucicarmine staining and characteristic immunohistochemistry markers confirming the diagnosis of CMEC. He subsequently underwent adjuvant radiotherapy and is disease free 5 years since treatment completion.
