Low-grade ovarian serous adenocarcinoma is rarely encountered in the neck region. The diagnosis of this rare malignancy entity in the neck is challenging for both clinicians and pathologists. A 53-year-old female with a chief complaint of a right lower neck mass that had been growing for approximately 2 weeks. The ultrasound-guided fine needle aspiration cytology favored malignancy. The positron emission tomography/computed tomography scan revealed the clustered enlarged lymph nodes with increased radioactivity uptake in the right neck level V, and strong radioactivity uptake was also displayed in the right ovarian regions. Pelvis magnetic resonance imaging displayed right adnexal complex mass supporting the ovarian cancer. An en bloc resection of the right neck lymph node was conducted. Ovarian serous adenocarcinoma with metastasis of lymph nodes in the neck was confirmed through histopathological findings. This study reviews the clinical features of low-grade ovarian serous carcinoma metastasizing to lymph nodes in neck. Although very rare, ovarian cancer with neck metastasis should be considered in the differential diagnosis of a neck mass lesion. The clinical staging would be relatively high due to the quiet entity of the cancer.

Ectopic salivary tissue is commonly found in intraparotid and periparotid lymph nodes. Warthin tumor is the most common tumor arising in ectopic salivary gland tissue and in intraparotid lymph nodes. Although rare, neoplastic transformation of the ectopic salivary tissues is conceivable and other types of salivary gland neoplasms arising in intraparotid lymph nodes have been reported. Herein we report a rare case of a 32-year-old Kuwaiti male who presented with a mass in the right parotid gland. A preoperative fine needle aspiration suggested Warthin tumor. The patient underwent a superficial parotidectomy. The specimen showed a mass within the parotid parenchyma abutting the deep margin. Hematoxylin and Eosin stained sections of the lesion showed solid islands and cysts composed of epidermoid cells, mucus cells, and intermixed smaller “intermediate” cells within an intraparotid lymph node. The tumor was seen infiltrating the parotid parenchyma at the deep margin. Metastasis from distant sites was ruled out clinically, and the diagnosis rendered was MEC, low-grade, arising from ectopic salivary tissue in an intraparotid lymph node. Such cases are extremely rare and the presence of malignancies within lymph nodes may pose a diagnostic pitfall, which can affect patient management.

Summary Aim: To visualise the sentinel lymph nodes (SLNs) of the prostate we injected the radiotracer into the parenchyma of the prostate. The activity was deposited in liver, spleen, bone marrow, urinary bladder and regional lymphatic system. The aim of this work is to determine biokinetical data and to estimate radiation doses to the patient. Methods: The patients with prostate cancer received a sonographically controlled, transrectal administration of 99mTc-Nanocoll®, injected directly into both prostate lobes. In 10 randomly selected patients radionuclide distribution and its time course was determined via regions of interest (ROIs) over prostate, urinary bladder, liver, spleen and the lymph nodes. The uptake in the SLNs was estimated from gamma probe measurements at the surgically removed nodes. To compare tumour positive with tumour free lymph nodes according to SLN-uptake and SLNlocalisation we evaluated 108 lymph nodes out of 24 patients with tumour positive SLN. For calculating the effective dose according to ICRP 60 of the patients we used the MIRD-method and the Mirdose 3.1 software. Results: The average uptake of separate organs was: bladder content 24%, liver 25.5%, spleen 2%, sum of SLN 0.5%. An average of 9% of the applied activity remained in the prostate. The residual activity was mainly accumulated in bone marrow and blood. Occasionally a weak activity enrichment in intestinal tract and kidneys could be recognized. The effective dose to the patient was estimated to 7.6 μSv/MBq. The radioactivity uptake of the SLN varied in several orders of magnitude between 0.006% and 0.6%. The probability of SLN-metastasis was found to be independent from tracer uptake in the lymph node. The radioactivity uptake of the SLNs in distinct lymph node regions showed no significant differences. Conclusion: The radiotracer is transferred out of the prostate via blood flow, by direct transfer via the urethra into the bladder and by lymphatic transport. Injecting a total activity of 200 MBq leads to a mean effective dose of 1.5 mSv. It is not recommended to use the tracer uptake in lymph nodes as the only criterion to characterize SLNs.

The Difference

AbstractLow-grade serous carcinoma (LGSC) is an infrequent subtype of ovarian cancer, corresponding to 5% of epithelial neoplasms. This subtype of ovarian carcinoma characteristically has molecular features, pathogenesis, clinical behaviour, sensitivity to chemotherapy, and prognosis distinct to high-grade serous carcinoma (HGSC). Knowing the difference between LGSC and other ovarian serous tumours is vital to guide clinical management, which currently is only possible histologically. However, imaging can provide several clues that allow differentiating LGSC from other tumours and enable precise staging and follow-up of ovarian cancer treatment. Characteristically, LGSC appears as mixed lesions with variable papillary projections and solid components, usually in different proportions from those detected in serous borderline tumour and HGSC. Calcified extracellular bodies, known as psammoma bodies, are also a common feature of LGSC, frequently detectable within lymphadenopathies and metastases associated with this type of tumour. In addition, the characterisation of magnetic resonance imaging enhancement also plays an essential role in calculating the probability of malignancy of these lesions. As such, in this review, we discuss and update the distinct radiological modalities features and the clinicopathologic characteristics of LGSC to allow radiologists to be familiarised with them and to narrow the differential diagnosis when facing this type of tumour.

IntroductionThere is limited evidence favoring the use of the sentinel lymph node technique in ovarian cancer, and no standardized approach has been studied. The objective of the present pilot study is to determine the feasibility of the sentinel lymph node technique by applying a clinical algorithm.MethodsPatients with confirmed ovarian cancer were included. 99mTc and indocyanine green were injected into the ovarian and infundubulo-pelvic ligament stump. A gamma probe and near-infrared fluorescence imaging were used for sentinel lymph node detection.ResultsThe sentinel lymph node technique was performed in ten patients with a detection rate in the pelvic and/or para-aortic region of 100%. The tracer distribution rates of sentinel lymph nodes in the pelvic and para-aortic regions were 87.5% and 70%, respectively.ConclusionThe detection of sentinel lymph nodes in early-stage ovarian cancer appears to be achievable. Based on these results, a clinical trial entitled SENTOV (SENtinel lymph node Technique in OVarian cancer) will be performed.

Here, we describe a case of a wild female badger (a sow) with disseminated serous adenocarcinoma of the ovary which corresponds to a group of low grade serous carcinomas of the ovary in humans. Beside grossly apparent dissemination of the disease we observed a scale of histological features classifiable as a precursor lesion – borderline serous tumour of the ovary with implant metastases at the peritoneum, and features of the borderline tumour transformation in the carcinoma. The latter features included invasion of some of the metastatic peritoneal implants into the adipose tissue of the mesentery, retroperitoneum, and in the muscle of diaphragm with lymphangioinvasion and with blood-borne metastatic disease in the lungs. The primary tumour and its metastases had a uniform cytological appearance without atypia of the tumour cells. Mitotic activity was exceptional. The proliferation activity as demonstrated by immunohistochemical investigation of Ki-67 protein expression (revealing all active phases of the cell cycle – G1, S, G2, M) showed a low proliferation activity of the tumour cells, comparable with findings in low grade carcinomas or borderline tumours of the ovaries in women. WT1 protein was expressed in the whole tumour cell population. All these features were diagnostic of serous carcinoma of the ovary with low grade malignant potential. Tumours of the ovaries in wildlife have been described previously but they are infrequent and are rarely classified histopathologically. This case report offers a parallel with serous carcinomas in human pathology including features of transformation from a precursor lesion of a borderline serous tumour into a serous low grade carcinoma.

ObjectiveThe aim of this study was to document the need of including the perigastric area when performing omentectomy in patients with stage III to IV serous epithelial ovarian tumors.Patients and MethodsPatients undergoing omentectomy in the setting of surgery for advanced epithelial serous ovarian cancer between February and September 2015 were included. Patients with macroscopic involvement of the perigastric area, nonepithelial serous tumors, and recurrences of ovarian cancer were excluded. The perigastric area was isolated and comprehensively processed for pathological examination.ResultsTwenty-four patients were included. Six patients underwent primary debulking surgery, and 18 patients underwent an interval debulking surgery. The mean number of pathologic blocks in the perigastric area was 24 (range, 8–41). Microscopic involvement of the perigastric omentum area was found in 62.5% of the cases. One patient had a low-grade serous carcinoma, with microscopic involvement of the perigastric area. Among the 23 patients with a high-grade serous carcinoma, 10 (83%) of 12 patients with a gross involvement of the rest of the omentum had a microscopic involvement of the perigastric area. The presence of microscopic disease in the perigastric arcade was found in 4 (36.3%) of 11 patients with a macroscopically normal omentum.ConclusionsIn this study, evidence is given that total omentectomy including the perigastric area is a necessary component of complete cytoreductive surgery in advanced ovarian cancer, whatever the macroscopic appearance of the omentum.

Abstract Background Due to the difficulty of dissection, surgical trauma, postoperative complications and other factors, the promotion of 3-field lymph node dissection is subject to certain restrictions. We try to explore and summarize a method of lymph node dissection, ‘endoscopic 2.5 lymph node dissection ’, that is, thoracoscopy combined with laparoscopic radical abdominal field, chest field and lower cervical paraesophageal lymph nodes (including 101 group below thyroid artery). Methods Retrospective analysis of 240 patients with thoracic esophageal squamous cell carcinoma from November 1, 2015 to December 31, 2017. All patients underwent endoscopic 2.5-field lymphadenectomy. The average age is (58.2 ± 9.5) years old. During the thoracoscopic part, when we do the lymphadenectomy along recurrent laryngeal nerves in the upper mediastimun and lower neck, we used a combination of ‘esophageal suspension method’, ‘lymph node rolling dissection method’ and ‘multi-angle pulling method’ to reveal the lymph nodes (Figure 1). Surgical related factors were collected and analyzed. Continuous follow-up was performed to record the recurrence and metastasis of patients and postoperative survival. Results Lymphadenectomy level of the right recurrent laryngeal nerve could reach the level above the right inferior thyroid artery, and the left could reach the level of 101 station. All operations were successfully completed. The incidence of pulmonary infection was 11.7%, the incidence of anastomotic leakage was 1.3%, the hoarseness rate was 7.9% and the incidence of chylothorax was 4.2%. The average number of total, abdominal and thoracic lymph nodes dissected were higher than the number of guidelines requirement and most of the previous literature. The average postoperative hospital stay was 8.4 days. The local recurrence rate, metastasis rate and survival rate of all the patients were not inferior to those reported in the past. Conclusion In patients with thoracic esophageal squamous cell carcinoma, the use of ‘total endoscopic 2.5-field lymph noede dissection’, could expand the range of lymph node dissection, and reached the super-thoracic and lower cervical level, which is beneficial to improve the degree of dissection along the recurrent laryngeal nerves. The procedure is safe and feasible, the results of short-term follow-up results are good, and it is worth further promotion. Disclosure All authors have declared no conflicts of interest.

Abstract Background We previously reported the performance of mediastinoscopic esophagectomy with lymph node dissection (MELD) under pneumomediastinum using a transcervical and transhiatal approach as a method of radical esophagectomy. For more complete lymph node dissection, it is necessary to dissect via not only left cervical but also right cervical approach in pneumomediastinum. We herein report the dissection method for upper mediastinum using a cervico-pneumomediastinal approach including right cervical approach in pneumomediastinum and the short surgical outcome. Methods This method was applied to nine cases for esophageal cancer. The right recurrent nerve was first identified using an open approach. Pneumomediastinum was then initiated to allow for the 105 and 106recR lymph nodes to be completely dissected along the right mediastinal pleura, the right vagus nerve, the proximal portion of the azygos vein and the right bronchial artery. The left recurrent nerve (106recL) lymph nodes and 106tbL lymph nodes were dissected using a cross-over technique, as described previously. Results This operation using bilateral cervical approach in pneumomediastinum were performed for nine cases. The median operation time and bleeding is 606 minutes and 506 ml, respectively. The median post-operative stay is 15 days. Conclusion MELD is therefore considered to be a more minimally invasive and useful modality for radical esophagectomy than the thoracic approach, although the field of view is different from that of the thoracic approach.
