Posterior trapezius myocutaneous flap.

Since last decade, myocutaneous flaps have appeared among the most versatile and safest options for the reconstruction of defects caused by large oncological resections, in the head and neck area. Undoubtedly, the myocutaneous flap of the pectoralis major muscle is the most widespread and accepted, due to the long experience obtained through its use. Nevertheless, it presents some restrictions related not only to its rotation arch, but also to the esthetic consequences for the donor site in females. Over the last years, there has been a growing interest in the posterior trapezius myocutaneous flap (PTMF), which proved to be a valuable alternative for reconstruction in selected cases. The experience of the Department of Head and Neck Surgery, at the University of São Paulo Medical School-Hospital das Clínicas, using this technique, is reported here in a detailed description.

[Brain metastases from papillary thyroid carcinoma: a case report and review of the literature].

Papillary carcinoma, the commonest thyroid malignancy, has a good prognosis and low incidence of distant metastases. Brain metastasis is extremely rare with a frequency of about 1% in reported series. In this paper we present the clinical details of one case of histologically proven brain metastasis from papillary thyroid cancer, first presented with neurological symptoms, initially treated with excisional biopsy and radiotherapy in other hospital, without clinical response. The patient was then referred to our service, where he underwent a total thyroidectomy and modified radical neck dissection, with the aim of posterior radioactive iodine treatment for the brain lesion. Unfortunately, he died of neurological complications, two months after the neck treatment. Also presented is a review of the literature of this unusual clinical presentation.

[Parathyroid cyst: case report].

Parathyroid cysts are very uncommon lesions, with about 200 cases in the literature. Differential diagnosis is difficult, particularly with thyroid mass and symptoms of cervical compression and hyperparathyroidism are described. We present a case in which the diagnosis was intraoperative and discuss the treatment of this unusual disease.
