BACKGROUND: Accurate nodal restaging is becoming clinically more important in patients with locally advanced rectal cancer (LARC) with the emergence of organ-preserving treatment after a good response to neoadjuvant chemoradiotherapy (nCRT). PURPOSE: To evaluate the accuracy of MRI in identifying negative N status (ypN0 patients) in LARC after nCRT. MATERIAL AND METHODS: 191 patients with LARC underwent MRI before and 6-8 weeks after nCRT and subsequent total mesorectal excision...

BACKGROUND: Sarcoidosis and hypersensitivity pneumonitis (HP) are two distinct clinical entities that share granulomatous inflammation, although each of them has specific clinical, radiologic and pathologic profiles. Coexistence of the two diseases have been described, suggesting, at least in some cases, a common biologic background. CASE PRESENTATION: We describe two patients showing the concurrent diagnosis of sarcoidosis and hypersensitivity pneumonitis. Case 1: a 51-year old never smoker man had a history of occupational exposure, episodes of acute exacerbations and positive serum precipitins to Penicillium spp suggestive of HP, while the positivity of serum angiotensin converting enzyme (ACE) favored sarcoidosis...

AIM: Evaluate impact of lymph node ratio as prognostic factor in gastric cancer. METHODS: We studied 463 patients with gastric cancer who underwent curative gastric surgery with D1 or D2 lymphadenectomy, Data were collected from May 1996 through December 2010 at Department of General Surgery of Parma University Hospital. We divided patients in two groups according to number of nodes removed Results: The results of the present nonrandomized retrospective single centre study confirm the promising role of the LNR as an independent prognostic factor...

INTRODUCTION: Ano-rectal melanoma is an uncommon finding in patients complaining of rectal bleeding and/or anal mass often misinterpreted as a haemorroidal pile. CASE REPORT: A 55-years-old woman, complaining of rectal bleeding, frequent anal pain and anal mass suspected for haemorroidal thrombosis was referred for evaluation and possible treatment. A brown polypoid mass arising from the anal canal/lower rectum with a maximum diameter of 6 cm was diagnosed. The hystological examination of the neoplasm, transanally removed, revealed the presence of a polypoid melanoma partially involving the resection margin...

BACKGROUND: The use of laparoscopy for the treatment of gastric cancer suffered some resistance among surgeons around the world, gaining strength in the past decade. However, its oncological safety and technical feasibility remain controversial. AIM: To describe the results from the clinical and anatomopathological point of view in the comparative evaluation between the surgical videolaparoscopic and laparotomic treatments of total gastrectomy with linphadenectomy at D2, resection R0...

The subject of this study is methods and results of treatment of 21 cases of lip cancer between 2007 and 2012, which included 15 men and 6 women, aged 48-63. In 18 cases it was squamous cell carcinoma, in other 3 basocellulare carcinoma. Of the hospitalized patients the following clinical stages were found: T1 - five, T2 - five, T3 - seven, T4 - four. We operated with several techniques, we performed: V-incision and surgery according to the Webster - one patient, Rutkowski - four, Estlander - four, Karpandzic - three; in the treatment of cancer of upper lip the frontal flap was used...

Imaging techniques, such as ultrasound imaging, computed tomography, positron emission tomography or magnetic resonance imaging, are highly accurate procedures for the detection of lymph node enlargement, but none of them has the same sensitivity in the biological definition and in the cause of enlargement. Therefore, a direct evaluation of corresponding lymph nodes is necessary in most cases and fine needle cytology (FNC) is one of the most frequently used techniques for this purpose. The same imaging procedures are often used to perform targeted biopsies including FNC...

INTRODUCTION: Neuroendocrine bladder cancer is extremely rare, with an estimated incidence of 0.35-0.70% of all bladder tumors. The small-cell carcinoma represents the most frequent histologic variant described. Small-cell carcinoma is an epithelial tumor associated with a more aggressive behavior and poorer prognosis than transitional cell bladder carcinoma. The overall survival rate at 5 years does not exceed 8%. At the time of presentation 59% of patients have clinical stage >T2 and 56% show metastatic disease...

AIM: In the last 20 years the laparoscopic surgery rapidly and successfully diffused for the treatment of benign diseases and recently also for the treatment of malignancy; newerteless, the laparoscopic gastrectomy for gastric cancer is still controversial, in relation to extreme difficulty of a radical surgical resection performing with an accurate lymphadectomy. The authors present a surgical experience of patients affected by advanced gastric cancer who underwent total or subtotal gastrectomy with videoassisted or entirely laparoscopic technique in order to evaluate the safety, feasibility, advantages and limits of this surgical approach...

Usually, left colon cancer metastasis concerns liver, abdominal lymph nodes and lungs. Other localizations are quite rare occurrences. In spite of this, some uncommon metastasis sites are reported in literature, such as: peritoneum, ovaries, uterus, kidney testis, bones, thyroid, oral cavity and central nervous system. We report two cases of unusual localizations of left colon cancer metastasis localization, one into the retroperitoneal space and the other at the left axillary lynphnodes and between liver and pancreas...

The development of sentinel lymph nodes biopsy rouses a newer interest to internal mammary lymph nodes region. We report a case of internal mammary sentinel lymph nodes biopsy of a woman with breast cancer leaded to stage migration. A 71 years old woman with upper medial quadrant left breast cancer is reported. The tumor is 2.5 cm in size. Marking of SLN with radionuclide (Tc99m) and with 2 dyes (Patent blue V and Indocyanin green) are done. Only internal mammary lymph node is established with lymphoscintigrapgy...

Insulin like-growth factor I (IGF-I) has been involved in the pathogenesis of a variety of human neoplasia due to the mitogenic and anti-apoptotic properties of its cognate receptor. In human thyroid carcinomas, we have previously documented an increased immunoreactivity of both IGF-I and the IGF-I receptor (IGF-I R) associated with up regulation of IGF-I mRNA . Immunoreactivity of IGF-I and cognate receptor positively correlated with tumor diameter and wide intrathyroidal extension but not with patient's gender and age or with the stage of the tumors and the occurrence of limph node metastases...

BACKGROUND: Villous duodenal adenomas are rare, tend to malignant alteration and recurrency if surgical procedures are not sufficiently radical. They are mostly localized in the second portion of the duodenum and close to a papilla and are prone to malignant alteration. CASE REPORT: In this paper we presented a 79-year-old female patient already operated on twice elsewhere due to obstructive jaundice caused by villous duodenal adenoma, using, firstly, cholecystectomy and T-tube drainage of the choledoclus, and, then, an unsuccessful attempt of radical surgery--duodenopancreatectomy...

The axillary lymph node status is the most important prognostic factor in breast cancer, and the axillary dissection as the gold standar for staging. It requires radical surgery, which is accompanied by importants postoperaive problems. Axillary lymph nodes can be imaged with a wide variety of available diagnostic radiological test (ultrasonography, mammography, computed tomography and magnetic resonance imaging). In these anatomic imaging, the limph nodes whit metastatic disease appear dense, enlarged or spiculated...

99mTc-MIBI scintigraphy has proven utility as a clinically valuable technique for the diagnosis of various primary and recurrent malignant lesions. We report the case of a 65 year old man with penile squamous cell carcinoma and clinically questionable bilateral inguinal lymph nodes. 99mTc-MIBI scan shows increased focal uptake in both groins and in the right iliac region. The patient underwent penile amputation with bilateral lymphadenectomy. Histopathologic report revealed metastatic lymph nodes in all lymphatic basins seen with 99mTc-MIBI...

BACKGROUND: Cutaneous T-cell lymphoma (CTCL) includes several lymphoproliferative disorders involving mature T-lymphocyte proliferation initially confined to the cutis. These affections, after variable periods, may progress to the blood, limph nodes and visceral organs. Mycosis fungoides (MF) is the most frequent form of CTCL and has an indolent clinical course. The therapy of CTCL depends on the stage of the disease and the patient's general conditions. For advanced cases it includes chemotherapy, retinoids, and interferon-alpha...

The Authors, using a personal dyeing method, specific for mast cells, that they described in a former work, (a modification of May-Gruenwald-Giemsa dye) observed crowd of mast cells in the subcutaneous tissue, below the site of thermal skin burns, in rats. They clearly demonstrate the phenomenon of mast cells degranulation. The granules are released in the subcutaneous tissue, then they go away along the limph vessels, and it is possible to follow them until the limph nodes. There is also crowd of limphocytes and plasma cells; nevertheless, there is evidence that mast cells are the early cells which react to burns in rats...

The role of the involvement of regional limph-node relays is already known, in the genesis of secondary lymphatic oedemas. With regard to the primary lymphatic oedemas however the role of regional lymph-nodes is considered to be limited. Following a complex investigation of an important clinical material the authors conclude that, in cases of primary lymphatic oedemas the determinat lesion is in the regional lymph nodes, and that it consists in an alteration of the filtration capacity, as well as in a reduction of the processing capabilities by the lymph nodes of the lymph flowing from the afferent lymph vessels...

A detailed representation is made of the technique used in the performance of thyroidography and an analysis is carried out of the authors' personal experience Thyroidography and thyroido-limphography have been applied in 40 patients with various diseases of the thyroid gland. The authors evaluate the method as being simple to perform, accessible, well tolerated and capable to provide significant morphological data (size of the lobes, the presence of retrosternal thyroid tissue, structure of the gland), also allowing for visualization of the cervical limph-nodes...

The semi-deep radiotherapy, performed by high-kilovoltage technique, fills a gap between superficial and megavolttherapy, as it renders possible an irradiation in focal depth of 2--4 cm, while largely preserving the deep underlying tissue. Besides which, every form of radiotherapy can be used, as under conventinal conditions. A further advantage exists in the markedly greater skin tolerance and in the low bone absorption of high-kilovoltage radiation, so that much higher focal doses can be achieved. This means that--in superficial processes--the high-voltage technique can replace the much more expensive therapy with accelerated electrons...
