RESUMEN

BACKGROUND: The incidence of neuroendocrine neoplasm (NEN) and related carcinoid syndrome (CaS) has increased markedly in recent decades, and women appear to be more at risk than men. As per other tumors, gender may be relevant in influencing the clinical and prognostic characteristics of NEN-associated CS. However, specific data on carcinoid syndrome (CaS) are still lacking. PURPOSE: To evaluate gender differences in clinical presentation and outcome of CaS. METHODS: Retrospective analysis of 144 CaS patients from 20 Italian high-volume centers was conducted. Clinical presentation, tumor characteristics, therapies, and outcomes (progression-free survival, PFS, overall survival, OS) were correlated to gender. RESULTS: Ninety (62.5%) CaS patients were male. There was no gender difference in the site of primary tumor, tumor grade and clinical stage, as well as in treatments. Men were more frequently smokers (37.2%) and alcohol drinkers (17.8%) than women (9.5%, p = 0.002, and 3.7%, p = 0.004, respectively). Concerning clinical presentation, women showed higher median number of symptoms (p = 0.0007), more frequent abdominal pain, tachycardia, and psychiatric disorders than men (53.3% vs 70.4%, p = 0.044; 6.7% vs 31.5%, p = 0.001; 50.9% vs. 26.7%, p = 0.003, respectively). Lymph node metastases at diagnosis were more frequent in men than in women (80% vs 64.8%; p = 0.04), but no differences in terms of PFS (p = 0.51) and OS (p = 0.64) were found between gender. CONCLUSIONS: In this Italian cohort, CaS was slightly more frequent in males than females. Gender-related differences emerged in the clinical presentation of CaS, as well as gender-specific risk factors for CaS development. A gender-driven clinical management of these patients should be advisable.

RESUMEN

BACKGROUND: Sellar/parasellar lesions have been studied in the adult and paediatric age range, but during the transition age their epidemiology, clinical manifestations, management and treatment outcomes have been poorly investigated. MATERIALS AND METHODS: An Italian multicentre cohort study, in which hospital records of patients with diagnosis of sellar/parasellar lesions during the transition age and young adulthood (15-25 years), were reviewed in terms of prevalence, clinical and hormonal features at diagnosis, and outcomes where available. Both pituitary neuroendocrine tumours (pituitary tumours, Group A) and non-endocrine lesions (Group B) were included. RESULTS: Among Group A (n = 170, 46.5% macroadenomas), the most frequent were prolactin and GH-secreting tumours, with a female predominance. Among Group B (n = 28), germinomas and Rathke cells cysts were the most common. In Group A, the most frequent hormonal deficiency was gonadal dysfunction. Galactorrhoea and amenorrhoea were relatively common in female patients with prolactinomas. Pre-surgical diabetes insipidus was only seen in Group B, in which also hormone deficiencies were more frequent and numerous. Larger lesions were more likely to be seen in Group B. Patients in Group B were more frequently male, younger, and leaner than those of Group A, whereas at last follow-up they showed more obesity and dyslipidaemia. In our cohort, the percentage of patients with at least one pituitary deficiency increased slightly after surgery. CONCLUSIONS: The management of sellar/parasellar lesions is challenging in the transition age, requiring an integrated and multidisciplinary approach. Hormone and metabolic disorders can occur many years after treatment, therefore long-term follow-up is mandatory.

RESUMEN

PURPOSE: Risk factors for sporadic GEP-NENs are still not well defined. To identify the main clinical risk factors represents the aim of this study performed by three Italian referral centers for NENs. METHODS: We performed a retrospective case-control study including 148 consecutive sporadic GEP-NENs and 210 age- and sex-matched controls. We collected data on clinical features, cancer family history and other potential risk factors. RESULTS: Mean age was 58.3 ± 15.8 years; 50% males, primary site was pancreas (50.7%), followed by ileum (22.3%). The 62.8% and 29.1% of cases were G1 and G2, respectively; the 40% had locally advanced or metastatic disease at diagnosis. Independent risk factors for GEP-NENs were: family history of non-neuroendocrine GEP cancer (OR 2.16, 95% CI 1.31-3.55, p = 0.003), type 2 diabetes mellitus (T2DM) (OR 2.5, 95% CI 1.39-4.51, p = 0.002) and obesity (OR 1.88, 95% CI 1.18-2.99, p = 0.007). In the T2DM subjects, metformin use was a protective factor (OR 0.28, 95% CI 0.08-0.93, p = 0.049). T2DM was also associated with a more advanced (OR 2.39, 95% CI 1.05-5.46, p = 0.035) and progressive disease (OR 2.47, 95% CI 1.08-5.34, p = 0.03). Stratifying cases by primary site, independent risk factors for pancreatic NENs were T2DM (OR 2.57, 95% CI 1.28-5.15, p = 0.008) and obesity (OR 1.98, 95% CI 1.11-3.52, p = 0.020), while for intestinal NENs family history of non-neuroendocrine GEP cancer (OR 2.46, 95% CI 1.38-4.38, p = 0.003) and obesity (OR 1.90, 95% CI 1.08-3.33, p = 0.026). CONCLUSION: This study reinforces a role for family history of non-neuroendocrine GEP cancer, T2DM and obesity as independent risk factors for GEP-NENs and suggests a role of metformin as a protective factor in T2DM subjects. If confirmed, these findings could have a significant impact on prevention strategies for GEP-NENs.

RESUMEN

BACKGROUND: Following the development of gender medicine in the past 20 years, more recently in the field of oncology an increasing amount of evidence suggests gender differences in the epidemiology of cancers, as well as in the response and toxicity associated with therapies. In a gender approach, critical issues related to sexual and gender minority (SGM) populations must also be considered. MATERIALS AND METHODS: A working group of opinion leaders approved by the Italian Association of Medical Oncology (AIOM) has been set up with the aim of drafting a shared document on gender oncology. Through the 'consensus conference' method of the RAND/University of California Los Angeles (UCLA) variant, the members of the group evaluated statements partly from the scientific literature and partly produced by the experts themselves [good practice points (GPPs)], on the following topics: (i) Healthcare organisation, (ii) Therapy, (iii) Host factors, (iv) Cancer biology, and (v) Communication and social interventions. Finally, in support of each specific topic, they considered it appropriate to present some successful case studies. RESULTS: A total of 42 articles met the inclusion criteria, from which 50 recommendations were extracted. Panel participants were given the opportunity to propose additional evidence from studies not included in the research results, from which 32 statements were extracted, and to make recommendations not derived from literature such as GPPs, four of which have been developed. After an evaluation of relevance by the panel, it was found that 81 recommendations scored >7, while 3 scored between 4 and 6.9, and 2 scored below 4. CONCLUSIONS: This consensus and the document compiled thereafter represent an attempt to evaluate the available scientific evidence on the theme of gender oncology and to suggest standard criteria both for scientific research and for the care of patients in clinical practice that should take gender into account.

RESUMEN

OBJECTIVE: The percentage of patients with thyroid cancer incidentally diagnosed during a (18) F-fluorodeoxyglucose Positron Emission Tomography with computed tomography (CT) (FDG-PET/CT) for nonthyroid diseases ranges between 26% and 50%. DESIGN: Retrospective assessment of the clinical and pathological features of thyroid incidentalomas at FDG-PET/CT, aiming to identify potential predictors of malignancy. PATIENTS: Fifty-two patients with incidental thyroid uptake at FDG-PET/CT were retrospectively included [38 W, age 64·1 ± 12·5 years (mean ± SD)]. An arbitrary cut-off level of 5·0 for the 'maximum standardized uptake value' (SUV max) was chosen to differentiate benign from malignant tumours. Complete thyroid function, neck ultrasonography (US) features, and cyto-histological results were reported for all cases. RESULTS: In our institution, the prevalence of incidental thyroid (18) F-fluorodeoxyglucose ((18) F-FDG) uptake was nearly 1·76%. The prevalence of focal uptake correlated with greater risk of malignancy (P < 0·01). In particular, the euthyroidism (P < 0·003) and a SUV max >5·0 (P < 0·0001) were associated with the diagnosis of thyroid cancer. Diffusely increased FDG-PET/CT uptake in the thyroid was related to benign conditions. CONCLUSIONS: The presence of focal uptake with high SUV max and euthyroidism correlate with high likelihood of malignancy. Performing a neck US would have to be recommended in all patients with euthyroidism and an incidental FDG-PET/CT focal thyroid uptake. We do not suggest to use FDG-PET/CT as a screening tool for thyroid cancer in the general population, because of both its high cost and low incidence of thyroid incidentaloma at FDG-PET/CT.

RESUMEN

BACKGROUND AND AIM: Familial adenomatous polyposis (FAP) is an autosomal inherited syndrome characterized by hundreds to thousands colorectal adenomatous polyps with oncological transformation lifetime risk of 100%. FAP is mainly associated with mutations in APC (autosomal dominant inheritance) or MUTYH (autosomal recessive inheritance) genes. Affected individuals are at increased risk of developing extra-intestinal tumors. Lifetime risk of developing thyroid carcinoma has been described in previous reports of about 2-12%, mainly in females, and the mean age is below 30 yr. About 95% of cancers are papillary thyroid carcinomas (PTC), mostly multifocal. The aim of this study was to evaluate the frequency of PTC among our series of FAP patients and to assess the type of gene mutation associated with the disease. METHODS: Fifty-four subjects from 36 FAP families were selected (29 females/25 males) and the mean age (±SD) at diagnosis was 28.8±10.8 yr. All patients underwent blood examination for thyroid hormones and antibodies, germline mutational analysis of APC and/or MUTYH genes, thyroid ultrasound, and endocrinological evaluation. RESULTS: In 13/54 (24.1%) subjects, an eumetabolic thyroid disease was found: plurinodular disease in 7/54 (13.0%); single nodule in 4/54 (7.4%); in 2/54 patients (3.7%), we found a malignant nodule characterized after total thyroidectomy as a classical PTC. Both patients were female and showed a classic FAP phenotype. Mutational analysis revealed in the first patient the APC germline mutation 3183_87del ACAAA and in the second patient the del9-10 (del9080dup11) novel APC variant; the first mutation has been already reported in association with PTC; to our knowledge the second mutation has never been previously reported in association with FAP. CONCLUSIONS: In the population examined, the estimated prevalence of thyroid malignant diseases was 3.7%. In both patients, the identified APC gene pathogenetic variants mapped within the 5' region of the gene, previously reported as a PTC-associated mutational hot spot. Both patients had classic FAP phenotype and genetic analysis revealed two pathogenetic APC mutations: c.3183_87delACAAA, a recurrent pathogenetic variant and del9-10 (del9080dup11), a novel, not previously described genomic rearrangement. In agreement with previous studies, the morpho-functional surveillance of thyroid in FAP series should be recommended. A better insight into the overall genotype-phenotype correlation of APC gene mutations would be helpful for the identification of at-risk individuals.

RESUMEN

Excess free iodide in the blood (ingested or injected) may cause thyrotoxicosis in patients at risk. Iodinated contrast solutions contain small amounts of free iodide and may be of significance for patients affected by Graves' disease, multinodular goiter or living in areas of iodine deficiency. Herein, we report a 57 elderly woman with a clinical history of multinodular goiter presented with a thyrotoxicosis induced by an iodinate contrast agent used during computed tomography scan. Because of the patient's resistance to conventional antithyroid drugs, she was treated with therapeutic plasma exchange (TPE). TPE is used in the treatment of several immunologic and nonimmunologic disorders. Temporary improvement after TPE in cases with thyrotoxicosis has been reported. In our patient's case, we observed an improvement in the thyroid hormone laboratory values as well as clinical findings. TPE can be an addition treatment when standard therapies for thyrotoxicosis fail providing the clinician with an adjuvant tool for rapid preparation of such a patient for thyroidectomy surgery.

RESUMEN

Gender- and sex- related differences represent a new frontier towards patient-tailored medicine, taking into account that theoretically every medical specialty can be influenced by both of them. Sex hormones define the differences between males and females, and the different endocrine environment promoted by estrogens, progesterone, testosterone, and their precursors might influence both human physiology and pathophysiology. With the term Gender we refer, instead, to behaviors, roles, expectations, and activities carried out by the individual in society. In other words, "gender" refers to a sociocultural sphere of the individual, whereas "sex" only defines the biological sex. In the last decade, increasing attention has been paid to understand the influence that gender can have on both the human physiology and pathogenesis of diseases. Even the clinical response to therapy may be influenced by sex hormones and gender, but further research is needed to investigate and clarify how they can affect the human pathophysiology. The path to a tailored medicine in which every patient is able to receive early diagnosis, risk assessments, and optimal treatments cannot exclude the importance of gender. In this review, we have focused our attention on the involvement of sex hormones and gender on different endocrine diseases.

RESUMEN

Insulin-secreting tumors are the commonest hormone-producing neoplasm of the gastrointestinal tract. They occur with an incidence of 4 cases per million per year. About 10% of them are metastatic and malignant insulinomas very rarely observed in children and in elderly. We report a rare case of very large malignant insulinoma in a 71-year-old woman admitted in our Oncological Institute on October 2005. She presented with fasting hypoglicemia (blood glucose 35 mg/dl) and high serum insulin levels (insulin 115.9 microU/ml). A computerized tomographic scan showed a pancreatic tail lesion of about 6 cm in max diameter and multiple liver metastases. A whole body scintiscan using 111In-DTPA-D-Phe1-octreotide was made and an increased uptake in the tail of the pancreas has been found. The patient was submitted to liver biopsy and the diagnosis of a metastatic insulin-secreting tumor was immunoistochemically confirmed. Due to the presence of some hypoglicemic episodes uncontrolled by medical treatment, on December 2005 the patient was admitted to surgical intervention with a body and tail pancreatic resection. Post-operatively the patient experienced again syncope with hypoglycemia and hyperinsulinemia. It was then decided to start a schedule of treatment with somatostatin analog (octreotide subcutaneously 500 microg three times a day) with a good control of blood glucose levels (101 mg/dl). A trans-arterial chemioembolization was planned but the patient died for pancreatic and cardiovascular complications before this treatment started.

RESUMEN

To verify whether the use of second generation ultrasonographic contrast agents leads to an improvement in the differential diagnosis of thyroid nodules, twenty patients, eligible for uninodular goiter surgery were studied. All patients previously underwent complete hormonal profile, bidimensional thyroid ultrasonographic, Colour Doppler evaluation and 99 mTc scintiscan. All nodules were as well evaluated before and after sulphur-hexafluoride administration. Wash-in time, contrast agent intra-nodular flow and wash-out time were evaluated. These data were compared with the cytology and histology findings. On the basis of the histological examination we divided our study population in 2 groups: in the group of neoplastic lesions (4 follicular adenomas and 6 carcinomas) an early wash-in was observed, with an homogeneous peripheral pattern enhancement, a rapid centripetal progression and an extended persistence of the contrast agent inside the nodule. In 6 out of 10 cases of thyroid neoplasia a fast wash-out was observed. In the group of benign lesions, in the patients affected by nodular goiter, an intra-nodular perfusion as opposite to the healthy surrounding parenchyma was observed. Even though ultrasound contrast agent technique has a limited invasivity and is more expensive than Fine Niddle Aspiration (FNA), the preliminary data of this pilot study suggest that this method might prove useful, to differentiate benign from malignant thyroid nodules.

RESUMEN

Few cases of malignant glucagonomas have been described in the literature. In this paper we present a case of a 77-year-old woman with necrolytic migratory erythema and high plasma glucagon and chromogranin A levels caused by a neuroendocrine tumour. An abdominal CT scan suggested a pancreatic lesion and two liver metastases. The patient underwent pancreatic debulking and liver metastasectomy. Histological and immunohistochemical investigations revealed a well differentiated neuroendocrine tumour with vascular invasion and scattered immunopositivity for somatostatin receptors. The patient was treated with octreotide (20 mg i.m. every 28 days) for three years without side effects. Three months after surgery symptoms of disease recurred accompanied by hyperglucagonaemia and newly diagnosed liver lesions. The patient was treated with octreotide (30 mg i.m. every 28 days) and interferon-alpha (6 MU s.cc 3 times per week) plus three cycles of hepatic chemoembolisation. Symptoms resolved after the first month of therapy, hormone levels decreased compared to untreated levels and metastatic growth slowed as observed by radiographic evidence. The patient is now asymptomatic with persistent hepatic disease and normal serum glucagon levels forty months after primary treatment. So far, only few immunohistochemical studies are reported on malignant glucagonoma and combined treatment schedules. We demonstrated, for the first time, a scattered immunopositivity for somatostatin receptors in a malignant glucagonoma. For this reason, the somatostatin analogs therapy was instituted. A combined antiproliferative medical treatment and the hepatic chemoembolization have been able to control tumor growth and disease symptoms for a long time after surgery.

RESUMEN

In papillary thyroid carcinoma lymphnode metastases at presentation do not seem to adversely affect survival, but do increase the risk of loco-regional tumor recurrence. The value of systematic versus selective lymphadenectomy is far less standardized, whereas the role of postoperative radioiodine in preventing either nodal recurrence or cancer death remains controversial. Clinical data of 36 N+ patients with papillary thyroid carcinoma who had undergone from 1990 to 1996 ipsilateral or bilateral neck dissection were retrospectively reviewed, to analyse the value of systematic lymphadenectomy. In our series of 50 extensive lymph node dissections (levels 2-6), the number of metastases in each specimen (mean value: 5) and the incidence of multiple level metastases (36%) were high. In 37.5% of the metastases at level 6 and in 11.1% at level 4, coexisting nodal involvement at level 2 was observed, without metastasization at intermediate levels. Multiple levels metastases and skip metastases were present in at least one third of the patients and could be excised only performing a complete dissection of the levels 2-6. Extra-capsular spread was found in 56% of the specimens. In 64.3% of these cases a functional neck dissection was performed. A modified radical or radical neck dissection was carried out in the other 35.7% of the cases. These patients received modified radical neck dissection (functional dissection with sacrifice of internal jugular vein) in 60% of the cases and radical neck dissection in the other 40%. In papillary thyroid carcinoma extensive lymphnode dissection at presentation has been stated to offer no advantage versus selective lymphadenectomy, causing increased morbidity. However, experienced surgeons report a low incidence (less than 5%) of accessory spinal nerve and cervical plexus permanent sequelae after functional neck dissection. In our opinion, patients with cervical lymph node metastases require a complete loco-regional neck dissection. Systematic lymphadenectomy, performed by lateral neck plus upper anterior mediastinal dissection, can yield a high disease-free survival. Moreover, this can limit the overall radio-iodine therapeutic dose and the risk of de-differentiation of recurrent tumor to the anaplastic type in patients with a long-term and near normal life-span.

RESUMEN

No data are currently available on the humoral autoimmune response against self heat shock proteins (hsps) possibly occurring in patients suffering from autoimmune thyroid disorders. Therefore, a preliminary research was carried out to assess whether anti-self hsps autoantibodies are present in human autoimmune thyroiditis (AIT). Serum samples from 14 patients with AIT were tested both in western blotting and in ELISA for antibody binding to protein extracts of human cultured cells (both unstimulated and heat-shocked) as well as to purified hsp 73 and hsp 72. It was found that 7 out 14 (50%) patients with AIT have autoantibodies of the IgM isotype strongly reacting with hsps 73/72. By contrast, autoantibodies to hsps 73/72 were detected only occasionally in sera from patients suffering from non-autoimmune thyroid disorders (1 out 11) as well as in sera from healthy individuals (2 out 9). No obvious clinical differences were detected between AIT patients who had autoantibodies to hsps 72/73 and those who did not. Clearly, more patients would have to be examined to determine whether the anomalous anti-hsps 73/72 autoimmune response occurring in a significant proportion of patients with AIT is in some way related to the pathogenesis and/or to the progression of the disease.

RESUMEN

Patients with thyroid microcarcinoma (TMC) have favourable long-term prognoses. However, recurrences in the neck and distant metastases have been reported. The authors investigated independent factors associated with recurrence in an effort to define therapeutic guidelines. In this study they report the results of a retrospective review of patients followed at one Institution. 120 patients ( 96 females and 24 males; mean age 45.2 years) with a papillary thyroid microcarcinoma (PTC) < or =1 cm in greatest dimension were analyzed. All of them were followed for 5 to 15 years. 106 of them were managed aggressively (total thyroidectomy), the remainder treated with lobectomy alone. Radioiodine therapy was performed in 62/106 patients submitted to total thyroidectomy. Despite the different treatment and the presence of neck node metastases at the time of the diagnosis in 26 of the reported 120 patients (22%) and local invasion beyond the thyroid capsule in 20 (17%), only 1.7% of patients had neck nodal local recurrence. No patient died or developed distant metastases. In this preliminary study the authors conclude that the outcome of PMC is generally favourable, even in presence of lymph-node metastases and local invasion, independently of the primary treatment.

RESUMEN

To assess the potential value of cytokeratins (CK) 8,18,19 as tumor markers for thyroid diseases, a study was performed comparing serum CK 8,18,19 levels in patients affected from thyroid carcinoma, adenoma, other benign thyroid diseases and healthy volunteers as controls. One hundred cases (65 patients and 35 controls) were examined. Thirty patients had thyroid carcinoma (18 papillary--PTC, 8 follicular--FTC, 4 medullary--MTC), 19 non-toxic goiter, 10 thyroid adenoma, 6 chronic thyroiditis and 35 healthy volunteers as controls. These controls were matched by age and sex. The mean value of CK in benign thyroid diseases (46.1 U/L) was significantly higher (p<0.02) than that in healthy controls (29.6 U/L). The mean value of CK in carcinomas (68.1 U/L) was significantly higher than that in healthy controls (p<0.01) and benign thyroid diseases patients (p<0.05). The positive rate of CK in thyroid carcinomas was 28.1%, while in benign thyroid diseases was 17.8%. The CK sensitivity for thyroid carcinomas was 28.1%, with a specificity of 80% and accuracy of 70.4%. In PTC patients the mean CK value was not significantly higher than in the benign diseases' group and in healthy subjects. No evident correlation between CK levels and tumor mass was found. In FTC patients the mean value was significantly higher than in the benign diseases' group and in healthy subjects. Large tumors showed the highest levels, while small tumor values were similar to the control ones. In MTC patients the mean value was significantly higher than in the benign diseases' group and in healthy subjects, with the highest peaks in large tumors and metastatic tumors. The detection of increased values in thyroid carcinomas with high metastatic potential (FTC and MTC) seems to confirm the role of these antigens in predicting the malignancy's degree of the neoplasm. These findings, if confirmed in larger series, could play an important role in assessing the CK 8,18,19 serum level as a real prognostic factor. Further repeated serum determinations after total thyroidectomy might indicate the role of CK 8,18,19 as serum markers predicting the risk of metastases.

RESUMEN

Adrenal metastases from Malignant Melanoma (MM) represent a debated therapeutical problem particularly in the case of disseminated disease. Surgical treatment, however, seems to be able to provide improvement on survival. Laparoscopic adrenalectomy is considered a gold standard procedure in benign adrenal disease but its value in malignancy, in terms of oncological effectiveness, is not known. A case of bilateral adrenal malignant melanoma metastases is reported. The patient, affected by superficial spreading melanoma of the right foot, eleven years after the primary developed a right adrenal metastasis. The relapse was treated by laparoscopic right adrenalectomy. One year later the patient had a new metastasis in the left adrenal gland and was submitted to laparoscopic left adrenalectomy. The two step laparoscopic bilateral adrenalectomy showed to be quite easy to perform, providing a complete removal of the whole glands, without adrenal tissue crushing and without neoplastic tissue dissemination in abdominal cavity. The postoperative course was excellent and the patient was discharged within about 72 hours after the two procedures. In literature only few reports indicate the feasibility of laparoscopic adrenalectomy for malignancy. In the reported case of malignant melanoma metastasis, minimally invasive adrenalectomy was very satisfactory and the good results obtained suggest its routine use.

RESUMEN

Between 1990 and 1997, 36 thyroid cancer patients were observed at the III Department of Surgical Oncology, Regina Elena Cancer Institute in Rome. There were 31 (86.1%) women and 5 (13.9%) men, with a mean age of 47.7 years (range 17-72). Diagnostic data consisted of: papillary carcinoma in 25 patients, follicular carcinoma in 9 and Hürthle cell carcinoma in 1. Twenty patients were less than 45 years old (15 papillary and 5 follicular carcinoma) and 16 were more than 45 years old (10 papillary and 4 follicular carcinoma, 1 Hürthle cell carcinoma and 1 with undifferentiated cancer). We performed total thyroidectomy in 32 cases and isthmectomy in 3 (2 papillary carcinoma, T1, < 45 years, 1 follicular carcinoma with minimal invasion). At the time of diagnosis, 6 patients with papillary carcinoma showed signs of local metastasis. No patients exhibited distant diffusion. A follow-up was performed at mean 41 months (2-84 months). Two patients with follicular carcinomas had been treated with radioiodine and showed disease progression with distant metastasis. Our results coincide with the literature on this topic. Total thyroidectomy is preferred, in low-risk patients as well, because subsequent radioiodine treatment and disease relapse monitoring are facilitated. Lateral cervical lymphadenectomy was performed only in cases when there was clinical evidence of metastasis and recurrent disease at this level has never been observed.

RESUMEN

This paper report a case of autonomously functioning thyroid nodule, firstly occurred in a 13 years old women, complicated 9 years later by hyperthyroidism, with no response to thyreostatic treatment, hystologically diagnosed as papillary carcinoma, in a thyroid gland affected by Hashimoto's thyroiditis, with cervical bilateral lymph node metastasis. In literature the rate of coexisting hyperthyroidism, chronic thyroiditis and differentiated carcinoma is low; thus thyroid malignancies are very rare in young people. In this patient the large autonomously functioning nodule was entirely made of neoplastic tissue, while in the remaining thyroid there was no evidence of adenomatous tissue. Moreover, thyreostatic treatment failed in controlling hyperthyroidism. The Authors consider these facts as indirect evidences that this is a rare case of hyperfunctioning differentiated thyroid carcinoma.
