Project description:Open resection of a large lipoma requires a large incision that may result in disfigurement from the scar. Endoscopic resection of the lipoma can have better cosmetic results. However, piecemeal removal of the lipoma has the disadvantage of fragmentation of the tumor before it can be determined whether it is benign or malignant. In this Technical Note, the technical details of endoscopically assisted en bloc resection of an anterior knee lipoma are described. This can provide a whole-block specimen for histologic examination.

Fatal bioprosthetic aortic valve endocarditis due to Cardiobacterium valvarum.

Project description:Cardiobacterium valvarum was isolated from the blood of a 71-year-old man with fatal aortic valve endocarditis. The API NH system was used for phenotypic characterization of the C. valvarum strain. This is the first case of infective endocarditis caused by C. valvarum in Germany and the first case worldwide affecting a prosthetic valve and lacking an obvious dental focus.

En bloc resection of a C4 chordoma: surgical technique.

Project description:The prognosis of aggressive benign and low-grade malignant tumors in the spine as in the limbs, seems to be mostly related to the feasibility of en bloc resection, while in the treatment of high-grade malignant tumors the protocols of treatment include the combination of chemotherapy, radiation and surgery. Indications, criteria of feasibility and surgical technique are extensively reported for the thoracic and lumbar spine. In the cervical spine few cases are reported of resection, due not only to anatomical constraint, but also to the rarity of finding a tumor accomplishing the criteria of feasibility. A case of double-approach vertebrectomy finalized to remove en bloc the body of C4 for a stage IA chordoma is reported. The first stage was posterior, aiming to remove the posterior healthy elements by piecemeal technique. The anterior approach consisted of contemporary right and left prevascular presternocleidomastoid approaches The specimen was submitted for the histological study of the margins, which resulted tumor-free. This technical note is finalized to confirm that en bloc resection of the vertebral body through total vertebrectomy is feasible in the midcervical spine by double approaches, provided the tumor involves only layers B and C, maximum extension sectors 5-8.
