Total thyroidectomy without prophylactic central neck dissection in clinically node-negative papillary thyroid cancer: is it an adequate treatment?
Identification alone versus intraoperative neuromonitoring of the recurrent laryngeal nerve during thyroid surgery: experience of 2034 consecutive patients
Background: The aim of this study was to evaluate the ability of intraoperative neuromonitoring in reducing the
postoperative recurrent laryngeal nerve palsy rate by a comparison between patients submitted to thyroidectomy
with intraoperative neuromonitoring and with routine identification alone.
Methods: Between June 2007 and December 2012, 2034 consecutive patients underwent thyroidectomy by a
single surgical team. We compared patients who have had neuromonitoring and patients who have undergone
surgery with nerve visualization alone. Patients in which neuromonitoring was not utilized (Group A) were 993,
patients in which was utilized (group B) were 1041.
Results: In group A 28 recurrent laryngeal nerve injuries were observed (2.82%), 21 (2.11%) transient and 7 (0.7%)
permanent. In group B 23 recurrent laryngeal nerve injuries were observed (2.21%), in 17 cases (1.63%) transient
and in 6 (0.58%) permanent. Differences were not statistically significative.
Conclusions: Visual nerve identification remains the gold standard of recurrent laryngeal nerve management in
thyroid surgery. Neuromonitoring helps to identify the nerve, in particular in difficult cases, but it did not decrease
nerve injuries compared with visualization alone. Future studies are warranted to evaluate the benefit of intraoperative
neuromonitoring in thyroidectomy, especially in conditions in which the recurrent nerve is at high risk of injury.

Follicular nodules (Thy3) of the thyroid: is total thyroidectomy the best option?
BACKGROUND: Identification of the best management strategy for nodules with Thy3 cytology presents particular problems for clinicians. This study investigates the ability of clinical, cytological and sonographic data to predict malignancy in indeterminate nodules with the scope of determining the need for total thyroidectomy in these patients. METHODS: The study population consisted of 249 cases presenting indeterminate nodules (Thy3): 198 females (79.5%) and 51 males (20.5%) with a mean age of 52.43 ± 13.68 years. All patients underwent total thyroidectomy. RESULTS: Malignancy was diagnosed in 87/249 patients (34.9%); thyroiditis co-existed in 119/249 cases (47.79%) and was associated with cancer in 40 cases (40/87; 45.98%). Of the sonographic characteristics, only echogenicity and the presence of irregular margins were identified as being statistically significant predictors of malignancy. 52/162 benign lesions (32.1%) and 54/87 malignant were hypoechoic (62.07%); irregular margins were present in 13/162 benign lesions (8.02%), and in 60/87 malignant lesions (68.97%). None of the clinical or cytological features, on the other hand, including age, gender, nodule size, the presence of microcalcifications or type 3 vascularization, were significantly associated with malignancy. CONCLUSIONS: The rate of malignancy in cytologically indeterminate lesions was high in the present study sample compared to other reported rates, and in a significant number of cases Hashimoto’s thyroiditis was also detected. Thus, considering the fact that clinical and cytological features were found to be inaccurate predictors of malignancy, it is our opinion that surgery should always be recommended. Moreover, total thyroidectomy is advisable, being the most suitable procedure in cases of multiple lesions, hyperplastic nodular goiter, or thyroiditis; the high incidence of malignancy and the unreliability of intraoperative frozen section examination also support this preference for total over hemi-thyroidectomy
Tall Cell Variant versus Conventional Papillary Thyroid Carcinoma: A Retrospective Analysis in 351 Consecutive Patients
Background: The aim of this retrospective study was to investigate clinical and pathological characteristics of the tall cell variant of papillary thyroid carcinoma compared to conventional variants. Methods: The clinical records of patients who underwent surgical treatment between 2009 and 2015 were analyzed. The patients were divided into two groups: those with a histopathological diagnosis of tall cell papillary carcinoma were included in Group A, and those with a diagnosis of conventional variants in Group B. Results: A total of 35 patients were included in Group A and 316 in Group B. All patients underwent total thyroidectomy. Central compartment and lateral cervical lymph node dissection were performed more frequently in Group A (42.8% vs. 18%, p = 0.001, and 17.1% vs. 6.9%, p = 0.04). Angiolymphatic invasion, parenchymal invasion, extrathyroidal extension, and lymph node metastases were more frequent in Group A, and the data reached statistical significance. Local recurrence was more frequent in Group A (17.1% vs. 6.3%, p = 0.02), with two patients (5.7%) in Group A showing visceral metastases, whereas no patient in Group B developed metastatic cancer (p = 0.009). Conclusions: Tall cell papillary carcinoma is the most frequent aggressive variant of papillary thyroid cancer. Tall cell histology represents an independent poor prognostic factor compared to conventional variants
Surgical management of gynecomastia: Experience of a general surgery center
Aim. Gynecomastia is a common finding in male population of all ages. The aim of our study was to present our experience and goals in surgical treatment of gynecomastia. Patients and Methods. Clinical records of patients affected by gynecomastia referred to our Department of Surgery between September 2008 and January 2015 were analyzed. 50 patients were included in this study. Results. Gynecomastia was monolateral in 12 patients (24%) and bilateral in 38 (76%); idiopathic in 41 patients (82%) and secondary in 9 (18%). 39 patients (78%) underwent surgical operation under general anaesthesia, 11 (22%) under local anaesthesia. 3 patients (6%) presented recurrent disease. Webster technique was performed in 28 patients (56%), Davidson technique in 16 patients (32%); in 2 patients (4%) Pitanguy technique was performed and in 4 patients (8%) a mixed surgical technique was performed. Mean surgical time was 80.72±35.14 minutes, median postoperative stay was 1.46±0.88 days. 2 patients (4%) operated using Davidson technique developed a hematoma, 1 patient (2%) operated with the same technique developed hypertrophic scar. Conclusions. Several surgical techniques are described for surgical correction of gynecomastia. If performed by skilled general surgeons surgical treatment of gynecomastia is safe and permits to reach satisfactory aesthetic results

Metastasi mammaria solitaria da carcinoma renale. Descrizione di un caso clinico
Metastasis to the breast are rare. A case of solitary breast metastasis from renal carcinoma is reported. A 75-year-old woman presented with a 4.5 cm, non-tender, mobile, well circumscribed lump in the upper quadrants of the right breast in march 1995. In September 1988 she had undergone right nephrectomy for a renal adenocarcinoma. Mammography revealed a mass with irregular borders and a fine needle aspiration biopsy was non diagnostic. An excisional biopsy revealed a breast metastasis from clear cell adenocarcinoma. Staging showed no evidence of further metastatic disease. The patient was disease-free until October 1999 when a liver ultrasound revealed a 4-cm metastasis and an abdominal CT scan 3 metastatic lesions in adrenal glands and duodenum. The patient died in December 2000. The recognition of breast neoplasm as being metastatic is important to prevent unnecessary radical surgery and to ensure appropriate therapy. Clinical and radiological diagnosis is not simple. In the case reported, in presence of a non-diagnostic cytology, the decision to proceed with an excisional biopsy permitted to avoid unnecessary radical surgery. The rare possibility that a breast lump is a metastasis should be kept in mind by physicians, radiologists and pathologists, in order to ensure appropriate treatment
