Myxofibrosarcoma involving the external saphenous nerve: a case report.

Myxofibrosarcoma, also known as "myxoid malignant fibrous histiocytoma" is one of the most common soft tissue sarcomas in the extremities of adult patients. Most cases are characterized by a multinodular and/or infiltrative pattern with a tendency to infiltrate along fascial planes. We report a case of myxofibrosarcoma with an unusual presentation. Despite the clinical impression of a complete surgical resection, microscopic sarcomatous foci extended along the perineurium of the external saphenous nerve proximally up to 20 cm away from the main tumour. This unique case represents an extreme example of the locally agressive behaviour of soft tissue sarcomas and illustrates the microscopic tumour invasion along major nerves.Case ReportsJournal ArticleSCOPUS: ar.jinfo:eu-repo/semantics/publishe

Thyroid carcinoma metastasis to the sternum: resection and reconstruction.

Metastases of thyroid carcinoma to the sternum are not so frequent and ablative surgery enables the patients to live longer with a better quality of life. After such a resection, the surgical defect has to be covered either by autogenous or artificial substitutes. We present a 62 years old patient with an asymptomatic sternal metastasis of a poorly differentiated follicular thyroid carcinoma. After radical excision, including the sternum, both clavicular heads and an upper mediastinal dissection, the defect was reconstructed in two layers, combining a Marlex mesh and a pedicled pectoralis major muscle flap. Postoperative course was uneventful and respiratory function was not disturbed.Case ReportsJournal Articleinfo:eu-repo/semantics/publishe

Extended esophagolaryngeal resection with parathyroid autotransplantation

Esopharyngolaryngeal resection for carcinoma of the cervical esophagus must he accompanied by resection of the thyroid gland, parathyroid bodies, and regional lymph nodes. In order to reduce long-term morbidity associated with the procedure, we performed parathyroid autotransplantation in two patients who underwent esophagolaryngeal resections. Grafting of the upper two parathyroid glands into the sternocleidomastoid muscle was carried out successfully in both cases. Graft function was rapidly restored. During the third postoperative week, blood levels of intact parathormone (PTH) reached 20 pg ml(-1) in the first case and 15 pg ml(-1) in the second, and the patients were successfully weaned off calcium and vitamin D supplementation. Parathyroid autotransplantation should be attempted in all cases of esophagolaryngeal resections provided that parathyroid glands are free of malignancy
