[Role of surgery in patients with metastases from melanoma. A case report].

Introduction: The prognosis of patients with melanoma varies according to the staging of disease at the moment of diagnosis. Melanoma can metastasize to every organ or tissue, but the most common site involved is locoregional. In selected patients surgery plays a central role with the possibility of changing the prognosis at distance.

Papillary microcarcinoma of the thyroid gland: analysis of prognostic factors including histological subtype.

Objective: To evaluate the prognosis of papillary microcarcinoma (PMC) of the thyroid.

Design: Prospective study.

Setting: Teaching hospital, Italy.

Prognostic factors of insular versus papillary/follicular thyroid carcinoma.

The study aims were to characterize patients with insular thyroid cancer and to provide data on patient outcome after surgical therapy. We compared nine patients with insular thyroid cancer at the Department of Surgical Science of "La Sapienza" University of Rome with 27 patients of similar age and tumor size who had follicular and papillary cancer, for a minimum follow-up period of 24 months (range, 24-72 months). All of the patients examined underwent total thyroidectomy.

Control results on a sample of patients subjected to total thyroidectomy for papillary carcinoma: proposal for a personal diagnostic-therapeutic follow-up.

Well-differentiated thyroid neoplasms may be included among the most frequently occurring thyroid carcinomas. Papillary ca. is without doubt the best behaved type.

Malignant thyroid nodules: comparison between color Doppler diagnosis and histological examination of surgical samples.

The aim of this study was to verify the reliability of the differential diagnosis between benign and malignant thyroid nodules on the basis of vascularization. The study was conducted on 108 patients with a scintigraphically "cold" thyroid nodule, including 54 carcinomas and 54 benign nodules. All patients underwent total thyroidectomy.
