RESUMO
Angiosarcoma of the thyroid is a rare and aggressive primary malignant tumour of the thyroid. We report the case of a 69-year-old woman who presented with a red and sore skin area at the right-anterior region of the neck. Ultrasound examination and computed tomography scan showed a non-homogeneous mass in the right thyroid lobe. Fine needle aspiration cytology was suggestive of atypical vascular proliferation and so the patient underwent right thyroid lobectomy. The specimen measured 6 × 5 × 2.5 cm, and a reddish nodule was found, including a whitish central area of maximum 4 cm in diameter. Immunohistochemistry showed CD31 and ERG positivity, while thyroglobulin, calcitonin and TTF-1 expression were negative, indicating a diagnosis of angiosarcoma.

OBJECTIVE: The p16 (p16(Ink4a)) tumor-suppressor protein is a biomarker for activated expression of human papillomavirus oncogenes. However, data are insufficient to determine whether p16 overexpression predicts the risk for progression of low-grade cervical intraepithelial neoplasia (CIN). This study was aimed at evaluating the risk for progression to CIN2 or worse during a 3-year follow-up of an unselected series of 739 patients with CIN1 biopsy specimens tested for p16 expression. METHODS: Positivity of p16 was defined as a diffuse overexpression in the basal/parabasal cell layers. Selection biases were ruled out using a control group of 523 patients with CIN1 biopsies not tested for p16 expression. Analysis was based on the ratio of progression rates. RESULTS: In the first year of follow-up, the 216 patients (29%) with p16-positive CIN1 had a higher progression rate (12.3%) than did the 523 patients with p16-negative CIN1 (2.2%) (rate ratio, 5.5; 95% confidence interval [CI], 2.59-11.71). In the second and third years, differences were smaller (rate ratio, 1.32 and 1.14, respectively) and not significant. The patients with p16-positive CIN1 also had a lower risk for regression to normal in the first year of follow-up (rate ratio, 0.55; 95% confidence interval, 0.42-0.71) and nonsignificant changes in the second and third years (rate ratio, 0.81 and 0.84, respectively). CONCLUSIONS: The patients with p16-positive CIN1 had an increased risk for progression that was concentrated in the first year of follow-up. Immunostaining of p16 could have a role in short-term surveillance of patients with CIN1. Further research should focus on midterm/long-term outcomes of p16-positive CIN1.

OBJECTIVES: To evaluate the frequency and correlates of non-adherence to follow-up among patients conservatively treated for CIN2-3. STUDY DESIGN: Study population comprised 1560 patients aged 25-64 years from a screening programme in northern Italy. The regional standard protocol was used as a reference. Multinomial logistic regression analysis was used to estimate the odds ratio probability of a patient being lost to follow-up (no check-ups within 27 months of treatment) or incompletely followed-up (1-3 negative check-ups) versus having 4 negative check-ups. RESULTS: Three hundred twenty-six patients (21%) were lost to follow-up, 678 (43%) were incompletely followed-up, 352 (23%) presented for 4 negative check-ups and 204 (13%) were diagnosed with persistent disease. The probability of no or incomplete follow-up was greater for patients who lived in the urban district, who were treated in private settings (versus screening centres), who exhibited a visibile squamocolumnar junction on pre-treatment colposcopy, who were treated with cold knife excision and local destructive therapy (versus loop diathermy excision), and whose surgical specimens had positive excision margins. CONCLUSIONS: Adherence to the reference protocol was poor. Factors involved in follow-up failures require greater clinical attention.
