Background: The introduction of ultrasonography and fine needle biopsy (FNB) has changed the approach towards thyroid pathology. At the Division of Surgical Oncology of the National Institute for Cancer Research in Genoa we use a complex diagnostic system for the selection of patients affected by thyroid pathologies. Our aim is to analyze this methodology and find the best diagnostic procedure for the individual patient., Methods: Between January 1982 and June 1997, 2500 patients (pts) were found to be affected by thyroid pathologies. The diagnostic procedures for thyroid pathologies are: physical examination and anamnesis, scintigraphy, ultrasonography, fine needle biopsy, blood dosages, radiography of trachea and aesophagus; some cases require Computerized Tomography of the neck and Magnetic Nuclear Resonance. At the end of the examinations 409 pts underwent surgery; we will be evaluating the diagnostic system of these patients., Results: We found from our data, that the group with the highest incidence of malignant tumors is characterized by a large number of instrumental examinations. In fact, 55/73 pts underwent all the instrumental exams, and in 21.1% a malignant tumor was found. These data are interesting, but more important is that only 409 patients out of 2500 underwent surgery 16.3%., Conclusions: We believe that one single instrumental examination is not enough to detect the characteristic of a thyroid nodule; the three most important examinations, scintigraphy, ultrasonography and cytology, would make it possible to select those cases which need a surgical approach. We believe that the 20% incidence in these cases can be considered good result, considering that the incidence of malignant tumors in thyroid pathologies is about 5% and that in these cases although the tumors were not malignant, they were operated on for functional or mechanical disorder.

Sarcoma of the breast are a rare group of neoplasms representing less than 5% of Soft Tissue Sarcomas (STS). Between 1980 and 1995 in the National Institute foe Cancer Research (IST) of Genoa, 2188 patients were submitted to surgery for breast cancer. Seven of them were found to be affected by sarcoma, confirmed by histologic diagnosis. All the patients were between 39 and 87 years-old. Surgical treatments were: wide excision (1 case), total mastectomy (2 cases), radical mastectomy following Halsted (4 cases). A case of a 53 year-old woman with a phyllodes tumor initially transforming in to liposarcoma is reported. The patient was submitted to surgery (total mastectomy) and nowadays is alive and free of disease after 29 months. All authors agree that the treatment for sarcoma of the breast is early and complete surgical excision of the mass. The role of chemotherapy and radiotherapy is still uncertain. Outcome is based on histologic type, degree of differentiation and tumor size.

The paper reports the case of a 53-year-old man admitted to hospital with melena. The initial diagnosis was bleeding duodenal ulcer; after 8 weeks of therapy the duodenal ulcer was completely healed, but renewed intestinal bleeding occurred three months later. Angiography of the upper mesenteric artery revealed a clear tumour form. A tumour of the small intestine the size of a fist was found during surgery. An ileal resection was performed. Histopathological tests confirmed the diagnosis of leiomyoma of the small intestine.
