    Abstract Introduction Intramedullary spinal cord metastasis is very rare. The majority are discovered incidentally during autopsy. Most symptomatic patients present with rapidly progressive neurological deficits and require immediate examination. Few patients demonstrate features of Brown-Séquard syndrome. Radiotherapy is the gold-standard of therapy for Intramedullary spinal cord metastasis. The overall prognosis is poor and the mortality rate is very high. We present what is, to the best of our knowledge, the first case of Intramedullary spinal cord metastasis of colorectal carcinoma presenting as Brown-Séquard syndrome. Case presentation We present the case of a 71-year-old Caucasian man with colonic adenocarcinoma who developed Intramedullary spinal cord metastasis and showed features of Brown-Séquard syndrome, which is an uncommon presentation of Intramedullary spinal cord metastasis. Conclusion This patient had an Intramedullary spinal cord metastasis, a rare form of metastatic disease, secondary to colonic carcinoma. The metastasis manifested clinically as Brown-Séquard syndrome, itself a very uncommon condition. This syndrome is rarely caused by intramedullary tumors. This unique case has particular interest in medicine, especially for the specialties of medical, surgical and radiation oncology. We hope that it will add more information to the literature about these entities.

    Hepatocellular carcinoma (HCC) is the most common primary malignancy of liver. Distant metastasis to various organs is well known. Skeletal metastasis is also reported to various locations. Vertebral metastasis has been reported mostly to thoracic spine. However, cervical spinal cord involvement leading to cord compression has been reported very rarely in literature. We present a case of 58-year-old male with liver cirrhosis presenting as neck pain. Further work-up revealed metastatic HCC to cervical spinal cord resulting in acute cord compression. Patient has been treated with neurosurgical intervention. PMID:28299213

    Full Text Available Abstract Introduction Although vertebral and epidural metastases are common, intradural metastases and intramedullary spinal cord metastases are rare. The indications for the treatment of intramedullary spinal cord metastases remain controversial. We present the first biopsy-proven case of an intramedullary spinal cord metastasis from adenocarcinoma of the prostate. Case presentation Our patient was a 68-year-old right-handed Caucasian man with a Gleason grade 4 + 3 prostate adenocarcinoma who had previously undergone a prostatectomy, androgen blockade and transurethral debulking. He presented with new-onset saddle anesthesia and fecal incontinence. Magnetic resonance imaging demonstrated a spindle-shaped intramedullary lesion of the conus medullaris. Our patient underwent decompression and an excisional biopsy; the lesion’s pathology was consistent with metastatic adenocarcinoma of the prostate. Postoperatively, our patient received CyberKnife® radiosurgery to the resection cavity at a marginal dose of 27Gy to the 85% isodose line. At three months follow-up, our patient remains neurologically stable with no new deficits or lesions. Conclusions We review the literature and discuss the indications for surgery and radiosurgery for intramedullary spinal cord metastases. We also report the novel use of stereotactic radiosurgery to sterilize the resection cavity following an excisional biopsy of the metastasis.

    Thyroid carcinoma initially presents with clinical symptoms due to metastatic lesions in less than 5% of cases. Spinal cord compression from an epidural metastatic lesion as a first symptom is extremely rare. One would expect such a presentation to occur much later in the course of the disease. We are presenting a case report of a follicular thyroid carcinoma that presented with spinal cord compression from a thoracic epidural metastatic lesion in a previously healthy 55-year-old male. A single metastasis of follicular thyroid carcinoma presenting with posterior spinal cord compression is rare. In this particular case, our management included a mid-thoracic laminectomy, followed by resection of the epidural lesion. Once the surgical pathology confirmed the diagnosis of a follicular thyroid carcinoma, the general surgery team performed a near total thyroidectomy, after which he received radioactive iodine therapy. The patient is symptom-free at his three-year follow-up. Initial presentation of follicular thyroid carcinoma with symptomatic thoracic myelopathy from an epidural metastasis is very uncommon. An early diagnosis and prompt surgical intervention provided an excellent outcome.

    Full Text Available The bone is a common site for metastasis in hepatocellular carcinoma (HCC. However, bone marrow metastasis from HCC is rarely reported, and its frequency is unclear. Here we report a rare case of bone marrow metastasis that presented as bicytopenia originating from HCC without bone metastasis. A 58-year-old man was admitted for investigation of a liver mass with extensive lymph node enlargement that was detected when examining his general weakness and weight loss. Laboratory findings revealed anemia, thrombocytopenia, mild elevated liver enzymes, normal prothrombin time percentage and high levels of tumor markers (α-fetoprotein and des-γ-carboxyprothrombin. Abdominal computed tomography showed multiple enhanced masses in the liver and multiple enlarged lymph nodes in the abdomen. A bone marrow biopsy revealed only a few normal hematopoietic cells and abundant tumor cells. Despite its rarity, bone marrow metastasis should always be suspected in HCC patients even if accompanied by cirrhosis.

    We report a case of rare involvement of the eye with choroidal metastasis from renal cell carcinoma presenting 08 years after the primary tumor was removed. The patient initially presented with cataract most probably induced by the tumor. After cataract extraction, tumor was detected when it induced vitreous involvement and retinal detachment. Enucleation was performed and an extraocular mass was also excised. Histopathology confirmed the diagnosis of metastasis from renal cell carcinoma in the ocular tumor, extraocular mass and the vitreous. (author)

    Full Text Available Medulloblastomas are highly malignant brain tumours, but only rarely produce skeletal metastases. No case of medulloblastoma has been documented to have produced skeletal metastases prior to craniotomy or shunt surgery. A 21-year-old male presented with pain in the hip and lower back with difficulty in walking of 3 months′ duration. Signs of cerebellar dysfunction were present hence a diagnosis of cerebellar neoplasm or skeletal tuberculosis with cerebellar abscess formation was considered. MRI of brain revealed a lesion in the cerebellum suggestive of medulloblastoma. Bone scan revealed multiple sites of skeletal metastases excluding the lumbar vertebrae. MRI of lumbar spine and hip revealed metastases to all lumbar vertebrae and both hips. Computed tomography-guided biopsy was obtained from the L3 vertebra, which revealed metastatic deposits from medulloblastoma. Cerebrospinal fluid cytology showed the presence of medulloblastoma cells. A final diagnosis of cerebellar medulloblastoma with skeletal metastases was made. He underwent craniotomy and histopathology confirmed medulloblastoma.

    Full Text Available Abstract Background Solid tumor metastasis to the epididymis is a rare occurrence and is mostly discovered incidentally at autopsy or after therapeutic orchidectomy for prostate cancer. Other primary carcinomas that have been demonstrated to metastasize to the paratesticular region include those originating in the stomach, kidney, ileum, and colon. Case presentation A 72-year-old gentleman presented with a firm and tender mass involving the right epididymis. On examination, he was jaundiced. Computed tomography of the abdomen demonstrated an obstructive stricture of the extra-hepatic bile ducts, in keeping with a cholangiocarcinoma, through which a metal stent was endoscopically inserted for symptomatic relief. Subsequent right radical orchidectomy yielded a diffusely infiltrative adenocarcinoma obliterating the epididymis, extending into the rete testis, vas deferens and spermatic cord and showing widespread vascular and perineural invasion. Residual epididymal, rete, and testicular tubules showed no in situ neoplasia. Morphologically and immunohistochemically the features were in keeping with a metastasis from a primary cholangiocarcinoma. Conclusion Only two cases of bile duct carcinoma metastasising to the male genital tract have previously been reported in the literature, the testis being the main site of metastasis in both cases. To our knowledge, this is the first described case of cholangiocarcinoma metastasising primarily to the epididymis, and presenting as a solitary epididymal metastasis in the absence of disseminated disease. It serves to highlight the importance of performing a thorough examination of the male external genitalia both clinically, in the follow up of cancer patients, and at autopsy.

    Full Text Available Most breast masses arise from the breast. Metastasis to the breast is fairly uncommon, but can occur in breast skin and parenchyma. In particular, leukemia and lung cancers, and MM may metastasize to the breast. Breast metastasis might be the first symptom or may occur during the course of other malignancies. Our case presented with a fixed mass in the upper-medial quadrant of her left breast during regular follow-up visits. The mean time to breast metastasis in patients with MM is 62 months (13-178. In our case this time was 48 months. In a case series with 7 patients hematological malignancies (Hodgkin lymphoma, non-Hodgkin lymphoma, and leukemia were the leading cause of breast metastasis, whereas in only 1 case the cause was MM. In another case series of 15 MM patients with metastasis to the breast, the primary tumor was frequently localized to the upper extremities and trunk. In a report of 250 conjunctival MM cases the mortality rate was significantly higher in patients with tumors >4 mm in vertical thickness. In another 45-case MM series tumors with a diameter >10 mm were associated with higher mortality rates. In our case the thickness of the tumor was 5 mm. In conclusion, histopathological evaluation should be mandatory in patients with known primary malignancies in order to differentiate new primary tumors, metastases, and benign tumors.

    With the progress of image-guided localization, body immobilization system, and computerized delivery of intensity-modulated radiation delivery, it became possible to perform spine radiosurgery. The next question is how to translate the high technology treatment to the clinical application. Clinical trials have been performed to demonstrate the feasibility of spine radiosurgery and efficacy of the treatment in the setting of spine metastasis, leading to the randomized trials by a cooperative group. Radiosurgery has also demonstrated its efficacy to decompress the spinal cord compression in selected group of patients. The experience indicates that spine radiosurgery has a potential to change the clinical practice in the management of spine metastasis and spinal cord compression.

    Primary urethral carcinoma is extremely rare, accounting for less than 1% of all female genitourinary tract cancers. To the best of our knowledge, this patient is the first reported case of primary urethral carcinoma presenting metastasis to eyes. The diagnosis of metastasis involving the choroids should be suspected in patient with history of carcinoma and a decreased visual acuity or any other visual symptom. Case presentation: A 43-year-old woman underwent a total hysterectomy, cystectomy and bilateral pelvic lymphadenectomy due a primary adenocarcinoma of the proximal urethra. Adjuvant pelvic radiotherapy and six cycles of chemotherapy using cisplatin were performed. The patient made follow-up with no evidence of oncologic disease. However, nine months later, the patient reported visual alterations. Ophthalmoloscopic examination showed choroid lesions in both eyes that were compatible with metastatic choroids tumor and nuclear magnetic resonance suggested bilateral retinal metastasis and left meningioma parasagittal in parietal region. She was undergoing a new palliative chemotherapy, but the disease developed and there were metastasis to bone four months later. The patient died fourteen months after the surgery. (author)

    Full Text Available Abstract Background Gastrointestinal metastsasis from the breast cancer are rare. We report a patient who presented with intestinal obstruction due to solitary caecal metastasis from infiltrating ductal carcinoma of breast. We also review the available literature briefly. Case presentation A 72 year old lady with past history of breast cancer presented with intestinal obstruction due to a caecal mass. She underwent an emergency right hemicolectomy. The histological examination of the right hemicolectomy specimen revealed an adenocarcinoma in caecum staining positive for Cytokeratin 7 and Carcinoembryonic antigen and negative for Cytokeratin 20, CDX2 and Estrogen receptor. Eight out of 11 mesenteric nodes showed tumour deposits. A histological diagnosis of metastatic breast carcinoma was given. Conclusion To the best of our knowledge, this is the first case report of solitary metastasis to caecum from infiltrating ductal carcinoma of breast. Awareness of this possibility will aid in appropriate management of such patients.

  17. Thyroid metastasis as initial presentation of clear cell renal carcinoma.

    2015-01-01

    Metastatic tumors account for 1.4-2.5% of thyroid malignancies. About 25-30% of patients with clear cell renal carcinoma (CCRC) have distant metastasis at the time of diagnosis, being the thyroid gland a rare localization [5%]. A 62-year woman who underwent a cervical ultrasonography and a PAAF biopsy reporting atypical follicular proliferation with a few intranuclear vacuoles "suggestive" of thyroid papillary cancer in the context of a multinodular goiter was reported. A total thyroidectomy was performed and the histology of a clear cell renal carcinoma (CCRC) was described in four nodules of the thyroid gland. A CT scan was performed and a renal giant right tumor was found. The patient underwent an eventful radical right nephrectomy and the diagnosis of CCRC was confirmed. Thyroid metastasis (TM) from CCRC are usually apparent in a metachronic context during the follow-up of a treated primary (even many years after) but may sometimes be present at the same time than the primary renal tumor. Our case is exceptional because the TM was the first evidence of the CCRC, which was subsequently diagnosed and treated. The possibility of finding of an incidental metastatic tumor in the thyroid gland from a previous unknown and non-diganosed primary (as CCRC in our case was) is rare and account only for less than 1% of malignancies. Nonetheless, the thyroid gland is a frequent site of metastasis and the presence of "de novo" thyroid nodules in oncologic patients must be always considered and studied.

    Metastatic epididymal and spermatic cord adenocarcinoma from epithelial tumors are a rare condition. The most frequent primary cancers are prostate, lung, kidney, gastrointestinal tumors and breast. In literature, there are very low number of cases reporting metastasis from pancreatic cancer to epididymis and spermatic cord. We report a case of 70-years old man with history of left orchiectomy for undescended testicle, who presented to our department with a palpable nodule in the right scrotum. Scrotal ultrasound revealed an inhomogeneous hypoechoic nodule of epididymis and/or spermatic cord. Neoplastic markers showed high levels of CEA (carcinoembryonic antigen) and bHCG (beta Human Chorionic Gonadotropin). The patient underwent right surgical scrotal exploration with orchifunicolectomy. Pathologic examination revealed pathologic tissue showing rare glandular structures. Immunohistochemistry profile was compatible with malign epithelial neoplasm with glandular differentiation. Total body CT-scan revealed pathologic tissue in pancreas between head and body and a suspect pathologic lesion in liver and 18-FDG PET-scan confirmed the pancreatic neoplastic mass and a suspect secondary hepatic lesion. Biopsy of pancreatic pathologic area was positive for ductal pancreatic adenocarcinoma. The patient was sent to oncologic evaluation and started chemotherapy. Malignancies of epididymis and spermatic cord are rare entities and, in literature, very low number of cases of metastasis from pancreatic carcinoma to epididymis and spermatic cord are described. Early differential diagnosis is fundamental mostly in those patients with age range unusual for testis cancers.

    2017-01-01

    A 65-year-old woman underwent surgery for right breast cancer (TIN1aM0) in December 2005. In March 2011, the breast cancer recurred with multiple lung and lymph node metastases. In February 2013, because of multiple brain metastases whole-brain radiation therapy was performed. In January 2014, she developed paralysis of the left leg. Spinal cord magnetic resonance imaging revealed a mass lesion (Th12 to L1 level) in the spinal cord, and she was diagnosed with intramedullary spinal cord metastasis (ISCM) from the breast cancer. Spinal cord irradiation reduced the metastasis and improved her paralysis. Although pharmacotherapy was continued, her metastases, with the exception of ISCM, progressed and she died of the disease in November 2014. It is necessary to diagnose ISCM at the time of its onset. Additionally immediate therapeutic intervention can significantly reduce the volume of ISCM, resulting in symptomatic relief from neurological deficit; in this case, radiation therapy was effective.

    Purpose : Primary sphenoid carcinoma is rare. It accounts for 0.3% of all primary paranasal sinus malignancies. Because of the rarity of sphenoid carcinoma, large series of patients with outcome and survival statistics are currently unavailable. So we followed up the 1 case of sphenoid sinus carcinoma treated in our hospital and reported the course of the disease. In a review of case reports and small series of patients, 2-year survival was 7%. Our case is alive at 29 months after diagnosis of sphenoid sinus carcinoma. Intramedullary spinal cord metastasis (ISCM) is an unusual complication of cancer. In our case rapidly progressive paraparesis and urinary retention developed at 25 months after diagnosis of sphenoid sinus carcinoma. MRI of the thoracic spines showed the intramedullary spinal cord tumor mass at T3 and T4 level with accompanying syringomyelia. Here we report a case of ISCM associated with syringomyelia which has developed after primary sphenoid sinus carcinoma with a review of literature about the clinical behavior and treatment of this lesion

    Full Text Available Thyroid gland is an uncommon site of metastasis, and metastasis to the gland secondary to nasopharyngeal carcinoma is seldom seen. We were only able to identify eight reported cases in the literature. A 61-year-old man, diagnosed case of nasopharyngeal cancer–second primary ( first primary-oropharynx, was found to have a thyroid nodule on routine follow-up positron emission tomography-computed tomography (PET-CT scan. There was no evidence of metastases at any other sites. The thyroid nodule was confirmed as metastatic carcinoma by fine needle aspiration cytology. He was treated with multimodal treatment comprising of surgery followed by reirradiation with concurrent chemotherapy. Subsequently, at the first follow-up (2 months after completion of all treatment, the patient remained asymptomatic, but the response assessment with PET-CT scan was suggestive of lung metastases with no evidence of locoregional disease. Although thyroid parenchymal metastasis is an uncommon occurrence and signifies a poor prognosis, in appropriately selected patients, aggressive therapy with reirradiation and chemotherapy may improve local control and quality of life.

    Distant metastasis of primary neoplasms is the main factor that limits the success of antineoplastic therapy. It can be regarded as an early or late event in the neoplastic process, and varies considerably with tumor type. The metastatic potential of a given tumor greatly influences prognosis. Tumor metastasis is not a single neoplastic event, rather, it involves several major steps: invasion of cells from the primary tumor into tissue, and penetration of blood and lymph vessels; release of tumor cell emboli into the circulation; arrest of the emboli in capillary beds of distant organs; invasion of the wall of the arresting vessel, infiltration into adjacent tissue, and multiplication; and growth of vascularized stroma into the new tumor as proliferating tumor cells invade the distant organ. Lodgement and invasion are complex events that are not fully defined. Arrest and lodgement appears to require a thromboembolic event in which the metastatic embolis (1 cell) contacts vascular endothelium and adheres to the wall with thrombis formation following aggregation of platelets and fibrin to the tumor cell(s). Invasion may involve: formation of collagenases by tumor cells; mechanical disruption; chemotactic factors. Metastatic patterns depend on the route of metastasis, tumor type, and target organ (favored soil). In general, carcinomas metastasize via lymphatics and sarcomas via hematogenous routes. Others, melanoma, mast cell tumors, etc., show mixed patterns. This knowledge is important when one is attempting to prognostically stage a tumor, especially when thoracic radiographs are negative. The question of enlarged regional lymph nodes will be discussed in lecture relative to specific tumor types. 4 refs., 1 tab.

    Full Text Available Spinal arterial vascularization is supplied by a large anastomotic net, making spinal ischemic events far less common than ischemic cerebral strokes. Polycythemia vera, due to blood hyperviscosity and activated platelet aggregation, is associated with a higher risk of arterial and venous thrombotic events. We report a patient with spinal cord transient ischemic attacks, a rarely presenting manifestation, and polycythemia vera, which highlights the thrombotic potential of this disease, and the requirement of exhaustive diagnostic workout of a spinal ischemic event.

    Full Text Available Purpose. Understanding the presentation of spinal cord injury (SCI due to tumours considering population distribution and temporal trends is key to managing SCI health services. This study quantified incidence rates, function scores, and trends of SCI due to tumour or metastasis over an 18-year time period in a defined region in Spain. Methods. A retrospective cohort study included in-and outpatients with nontraumatic SCI due to tumour or metastasis admitted to a metropolitan hospital in Spain between 1991 and 2008. Main outcome measures were crude and age- and sex-adjusted incidence rates, tumour location and type, distribution by spinal level, neurological level of injury, and impairment ASIA scores. Results. Primary tumour or metastasis accounted for 32.5% of nontraumatic SCI with an incidence rate of 4.1 per million population. Increasing rates with age and over time were observed. Major pathology groups were intradural-extramedullary masses from which meningiomas and neurinomas accounted for 40%. Lesions were mostly incomplete with predominant ASIA Grade D. Conclusions. Increasing incidence rates of tumour-related SCI over time in the middle-aged and the elderly suggest a growing need for neurooncology health resources in the future.

    Split cord malformation (SCM) is a rare form of spinal dysraphism in which the spinal cord is divided in the sagittal plane, forming a double neural tube. In addition to being associated with a variety of malformations, SCM may occur with spinal cord tumors, with only exceptional cases involving teratomas. As only eight patients with a teratoma associated with SCM have been reported, their presentation characteristics and treatment are currently unclear. We review the literature of all patients with SCM with concurrent spinal teratoma, discuss the potential dysembryology, and report the first case of SCM with concurrent spinal teratoma in an elderly patient. The mean age of those with concurrent SCM and teratomas was 39.4 years, with 55.6% occurring in females. The lumbar spine was the most frequent location for teratomas (66.7%), with the Type II malformation more commonly occurring with these tumors (75%). The duration of symptoms varied widely, ranging from 1 month to 5 years, with the average duration being nearly 2 years. Back pain (87.5%) and lower extremity weakness (75%) were the most common presenting symptoms. As SCM may be associated with progressive neurological deterioration and teratomas can contain immature or malignant components, surgery should be attempted with the goal of gross total resection. Nonetheless, in patients with a concurrent tumor and spinal dysraphism, spinal teratomas should be considered in the differential diagnosis. Gross total resection of these lesions may be safely achieved even in the presence of SCM using intraoperative electrophysiologic monitoring. Copyright © 2013 Elsevier Ltd. All rights reserved.

    It is well-known that malignancies, particularly pancreatic and brain cancers, often present as venous thromboembolism. However, stroke and angina attributable to arterial occlusion are relatively common presentations as well. We are reporting a patient, with treatment-naïve hepatitis C and multiple liver nodules, was admitted for deep vein thrombosis (DVT) and pulmonary embolism (PE). Subsequently, she developed an ascending paralysis due to spinal cord infarct (SCI) despite adequate anticoagulation. She also had an enlargement of left supraclavicular lymph node, which was confirmed histologically metastatic cholangiocarcinoma. To our best knowledge, this is the first literature report showing the association linking SCI to metastatic cholangiocarcinoma as a consequence of hypercoagulable state of malignancy.

    2008-01-01

    Detailed herein are two cases of small cell lung cancer first presenting with orbital metastasis. Orbital metastasis from solid tumors is a rare entity. The predominating primaries in Western countries are breast and lung tumors; hepatocellular and gastric malignancies lead in Japanese series. Clinical symptoms and findings reflect the mass effect and the degree of extra-ocular muscle invasion. Treatment is guided by the cancer type and the tumor histology. The prognosis is grim, and with the exception of rare cases secondary to hormone-responsive tumors, the majority of patients succumb to their disease within a year of diagnosis.

    Brain metastasis from uterine cervical cancer is rare, with an incidence of 0.5%, and usually occurs late in the course of the disease. We report a case of uterine cervical cancer with brain metastasis as the initial site of presentation. A 50-year-old woman with headache, vertigo, amnesia and loss of appetite was admitted for persistent vomiting. Contrast enhanced computed tomography showed a solitary right frontal cerebral lesion with ring enhancement and uterine cervical tumor. She was diagnosed with uterine cervical squamous cell carcinoma with parametrium invasion and no other distant affected organs were detected. The cerebral lesion was surgically removed and pathologically proved to be metastasis of uterine cervical squamous cell carcinoma. The patient underwent concurrent chemoradiotherapy, followed by cerebral radiation therapy, but multiple metastases to the liver and lung developed and the patient died 7 months after diagnosis of brain metastasis. © 2015 The Authors.

    2015-01-01

    Full Text Available Background. Gestational choriocarcinoma (GC is a recognized clinicopathological subtype of gestational trophoblastic neoplasia that usually metastasizes hematogenously to highly vascular organs like the lung, liver, and brain. However, orbital metastasis to the choroid and lacrimal gland is a rare occurrence. Case Presentation. A 21-year-old female presented with headache and left orbital swelling one year after resection of a complete hydatidiform mole followed by adjuvant methotrexate chemotherapy. A metastatic imaging screening revealed multiple metastases in the lungs, brain, and adrenal gland, in addition to the choroid and lacrimal gland. Based on her modified WHO risk factors scoring she was started on chemotherapy and whole brain radiotherapy, which resulted in a complete response. At two-year follow-up, serum b-HCG level was with normal limits; imaging surveillance was uneventful. Conclusion. We present the first case of lacrimal gland metastasis in a young girl from GC relapse.

    Metastasis of a phyllodes tumor to the stomach is an extremely rare condition with important clinical implications. A 44-year-old woman was initially diagnosed with a phyllodes tumor in her right breast in 2008, and subsequently presented to an outpatient clinic with dizziness on December 16, 2013. We found that she had severe anemia (hemoglobin levels, 6.7 g/dL), and we quickly performed esophagogastroduodenoscopy to identify the cause. This procedure revealed large ulcerofungating masses with active bleeding in the stomach. Histopathological examination revealed that the masses were consistent with phyllodes tumor metastases. In patients with a metastatic phyllodes tumor presenting as anemia, gastric metastasis should be considered as one of the differential diagnoses because overlooking the possibility might have dire consequences if cytotoxic chemotherapy were administered.

    Full Text Available Abstract Background Excavated pulmonary metastasis are rare. We present two cases of excavated pulmonary nodules proved to be metastases from osteosarcoma and gallblader lymphoma. Case presentation The first one is 39-year-old man in whom cholecystectomy made the diagnosis of primary non-Hodgkin's lymphoma of the gallbladder. He presented in chest CT scan excavated nodules that had been biopsied and confirmed the diagnosis of non hodgkin lymphoma. He underwent 8 courses of chemotherapy CHOP 21 with complete remission. The second one is an 21 years old man who presented a right leg osteoblastic osteosarcoma with only excavated pulmonary nodules in extension assessment. He had 3 courses of polychemotherapy API (doxorubicin, platinum, and ifosfamide with partial response. Unfortunately, he died following a septic shock. Review of the literature shows that excavated pulmonary nodules as metastasis are rare but we should consider this diagnosis every time we are in front of a cancer. Chest computed tomography is the best diagnosis imaging that could make this diagnosis. Differential diagnosis between benign and malignant bullous lesions is important because surgical excision affects survival in some malignancies. Conclusions Although pulmonary nodules are the most common cancer metastasis, a differential diagnosis of a concurrent primary malignancy should always be considered every time we have excavated lesions, even in patients with known malignant disease. Thorough chest evaluation is important, as multiple primary malignancies may occur concomitantly.

    Wegener’s granulomatosis (WG) causing spinal cord compression is very rare with only few cases reported in literature. We present a case report with review of literature. A 55-year-old lady with known WG presented with acute on chronic spinal cord compression. MRI scan revealed spinal cord compression anteriorly and posteriorly at T2–T5 level. Patient underwent urgent surgical decompression with excision of the posterior dural lesion with synthetic duraplasty. Patient made good neurological recovery. Histopathology revealed features consistent with WG. A rare case of spinal cord compression from WG is presented. Urgent surgical decompression with duraplasty resulted in good neurological outcome.

    2017-01-01

    Full Text Available Tumors of thymus gland are rare and account for 0.2% to 1.5% of all the neoplasms. They constitute a heterogeneous group that has an unknown etiology and a complex as well as varied biology. This has led to difficulty in their histological classification and in predicting their prognostic and survival markers. Among them, thymic carcinoma is the most aggressive thymic epithelial tumor exhibiting cytological malignant features and a diversity of clinicopathological characteristics that can cause diagnostic dilemmas, misdiagnosis, and therapeutic challenge. We herein describe a case of a 60-year-old man who while undergoing evaluation for the cause of pancytopenia was discovered having bone marrow metastasis from an asymptomatic thymic carcinoma. Bone marrow metastasis is an extremely rare initial presentation of thymic carcinoma with only few cases reported in the literature.

    Anaplastic thyroid cancer is the rarest tumour of the thyroid gland, representing only 2% of clinically recognised thyroid cancers. The most common metastatic sites are lungs, followed by the intrathoracic and neck lymph nodes. We report the case of a 62-year-old woman who presented to our setting with multiple soft tissue nodules, thyroid mass, head swelling and weight loss. Radiological investigation showed a large thyroid mass with widespread metastasis in subcutaneous tissues of both upper limbs, chest and abdomen. Metastasis was also found in lungs, skull and adrenal glands after which the patient was diagnosed with stage IVc anaplastic thyroid carcinoma (ATC). After careful consideration of patient's clinical condition with multiple poor prognostic factors, medical therapy was withheld and she was discharged on hospice care. The patient expired after 1 month. In ATC, metastasis to subcutaneous tissue is an extremely rare occurrence of which there is hardly any evidence in literature. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

  6. An Unusual Clinical Presentation of Gastrointestinal Metastasis From Invasive Lobular Carcinoma of Breast

    Directory of Open Access Journals (Sweden)

    Bathmapriya Balakrishnan MD

    2016-03-01

    Full Text Available Introduction. We present an unusual case of metastatic lobular breast carcinoma. Typical areas of metastasis include bone, gynecological organs, peritoneum, retroperitoneum, and gastrointestinal (GI tract, in order of frequency. With regard to GI metastasis, extrahepatic represents a rare site. Case. Two years after being diagnosed with invasive lobular breast carcinoma, a 61-year-old female complained of 3 months of nonspecific abdominal pain and diarrhea. A colonoscopy revealed 5 tubular adenomatous polyps in the ascending and transverse colon. Contrast computed tomography (CT of the abdomen and pelvis was done 7 months after the colonoscopy to further evaluate persistent diarrhea. The CT results were consistent with infectious or inflammatory enterocolitis. Despite conservative management, symptoms failed to improve and a repeat diagnostic colonoscopy was obtained. Random colonic biopsies revealed metastatic high-grade adenocarcinoma of the colon. Discussion. Metastatic lobular breast carcinoma to the GI tract can distort initial interpretation of endoscopic evaluation with lesions mimicking inflammation. The interval between discovery of GI metastasis and diagnosis of lobular breast cancer can vary widely from synchronous to 30 years; however, progression is most often much sooner. Nonspecific symptoms and subtle appearance of metastatic lesions may confound the diagnosis. A high index of suspicion is needed for possible metastatic spread to the GI tract in patients with a history of invasive lobular breast carcinoma. Perhaps, patients with nonspecific GI symptoms should have an endoscopic examination with multiple random biopsies as invasive lobular carcinoma typically mimics macroscopic changes consistent with colitis.

    1991-01-01

    A 64-year-old woman presented with periorbital induration of 6 months' duration. Computed tomography (CT) revealed enlargement of extraocular muscles. A biopsy specimen of the orbicularis muscle and indurated preaponeurotic fat demonstrated an infiltrating carcinoma, and immunoperoxidase studies for surface antigens suggested a metastatic adenocarcinoma. Extensive evaluation revealed a 1-cm subareolar breast mass, with histopathological features identical to those of the orbital lesion. Orbital metastasis presenting before the diagnosis of a primary breast cancer is unusual, particularly in the absence of other disseminated disease.

    Brain tuberculosis is still prevalent in many developing countries, especially Asian countries. Tuberculomas should always be considered in the differential diagnosis of enhancing intra-axial lesions of the brain. Brain tuberculomas can present in many different clinical and radiological patterns clinically like headache, fits, cranial nerve palsies and very rarely as brain tuberculomas. We describe the case of a 48 years old male patient presenting with persistent headache and fits, referred for workup of brain metastasis or primary brain neoplasm. On further imaging, it turned out to be multiple tuberculomas of brain which resolved on anti-tuberculous treatment along with symptoms relief. (author)

  9. Umbilical cord prolapsed through urethra: An unusual presentation of a vesico-uterine fistula

    Aneela G Kamil

    2013-01-01

    Full Text Available Umbilical cord prolapse occurs when a loop of cord is present below the presenting part when the amniotic membranes are ruptured. The incidence is 0.2% of total births. The case presented here is unusual because the definition of cord prolapse cannot be applied to it and the lady did not complain of any history of urinary incontinence or hematuria. The presentation of umbilical cord through maternal urethra led to the speculation of an opening between the anterior uterine wall and the bladder. Fetal demise was diagnosed by abdominal ultrasound. At laprotomy, a communication was found between the bladder and the uterus thus letting the cord traverse through the bladder.

    Pituitary gland metastasis from primary tumours is uncommon on its own. Rarely, some of these primary tumours may be of unknown origin. This metastasis to the pituitary gland could manifest as diabetes insipidus, cranial nerve palsies, headaches, fatigue and other symptoms. In rare cases, it could present as loss of libido. We describe here this rare presentation, loss of libido, examine the diagnosis and management undertaken, and provide a systematic review of the literature for similar cases. 2015 BMJ Publishing Group Ltd.

    One of the most important prognostic factors in oral squamous cell carcinoma (OSCC) is the presence of lymph node metastasis. Therefore, the early detection of late-presenting cervical lymph node metastasis is important. Although many studies have assessed diagnostic modalities for detecting metastatic cervical lymph nodes, no study has evaluated the process, especially first signs, for detecting late-presenting cervical lymph node metastasis. A retrospective analysis comparing methods for detecting the first signs of late-presenting lymph node metastasis was performed. A total of 65 OSCC patients were assessed. These patients were identified retrospectively as having presented late metastasis during follow-up after initial treatment with curative intent. The findings of four detection methods were analyzed: palpation, ultrasonography, computed tomography, and subjective symptoms. The numbers of cases identified by each method were as follows: palpation, 31 (47.7%); ultrasonography, 17 (26.1%); computed tomography, 12 (18.5%); and subjective symptoms, 5 (7.7%). Palpation played a major role in the discovery of late-presenting lymph node metastasis. In contrast, metastatic lymph nodes were detected by other methods in about half of the cases. The results suggest a possible stratification of the various methods used for metastatic lymph node detection, depending on the characteristics of individual cases.

    Spinal cord involvement in gliomatosis cerebri (GC) is uncommon. We report two patients with GC, who initially presented with chronic meningitis and were treated with antituberculous drugs. Although tumor meningitis was suspected, due to the intractable clinical course, a correct diagnosis was established after performing a biopsy examination of the metastatic spinal lesion which was detected by magnetic resonance imaging (MRI). Cerebrospinal fluid examination, including cytology, should be performed repetitively for patients with chronic meningitis refractory to antibiotic treatment. Spinal MRI is necessary for the complete neurological workup, even when the patients do not show spinal symptoms. Copyright © 2012. Published by Elsevier B.V.

    Full Text Available Although brain has been the most common site for toxoplasma infection in acquired immunodeficiency syndrome patients, involvement of spinal cord by toxoplasma has been rarely found. Spinal cord toxoplasmosis can present as acute onset weakness in both lower limbs associated with sensory and bladder dysfunction. A presumptive diagnosis can be made in patients with CD4 count <100/mm 3 based on a positive serum Toxoplasma gondii IgG antibodies, no recent prophylaxis against toxoplasmosis, intramedullary ring enhancing lesion in spinal cord supported by similar lesions in brain parenchyma. Institutions of antitoxoplasma treatment in such patients result in prompt clinical response and therefore avoiding the need of unnecessary invasive diagnostic tests. Here, we report a case of toxoplasmic myelitis in immunocompromised patient presenting as myelopathy who showed significant clinical improvement after starting antitoxoplasma treatment. Hence toxoplasmic myelitis should be considered in toxoplasma seropositive immunocompromised patients presenting as myelopathy and imaging studies showing ring enhancing intramedullary lesion.

    2012-11-01

    Full Text Available This is a case study of a 61-year-old male who presented with difficult defecation for 1 month. A circumferential submucosal rectal tumor was noted on a digital rectal examination and colonoscopy. Laboratory examination revealed high serum levels of carcinoembryonic antigen (CEA; 43.75 ng/mL and carbohydrate antigen 19-9 (CA19-9; 11,790 U/mL. In addition, tumor biopsies revealed a poorly differentiated adenocarcinoma of the rectum with intact mucosa. The patient had history of advanced stage-T2 urothelial cell carcinoma of bladder, which had been downstaged to T0 by neoadjuvant chemotherapy followed by radical cystectomy 1 year prior. After investigating the initial bladder tumor specimens, a small portion of the tumor with high CEA expression comparable to the submucosal rectal tumor was found. The size of the tumor was reduced and the levels of the tumor markers decreased after administering FOLFIRI chemotherapy targeted at the adenocarcinoma. Although neoadjuvant chemotherapy may have a selective pressure to eliminate most urothelial cell carcinoma, physicians should be aware that it can lead to rectal metastasis via CEA-producing components.

    2017-05-01

    Renal Clear Cell Carcinoma (RCC) comprises over 80% of renal malignancies in adults. Thyroid gland metastasis is rare in RCC. Few studies have described cases of RCC mistaken for benign arteriovenous malformation (AVM). To the best of our knowledge, an AVM arising from underlying RCC metastasis to the brain has not yet been reported. The current study presents a case of RCC metastasis to the thyroid gland, with an AVM identified to be a result of metastatic involvement in the brain. A 45-year-old African-American female presented with left-sided weakness, slurred speech, facial droop and seizure. The patient's medical history was notable for a diagnosis of RCC, 2010 American Joint Committee on Cancer Tumor-Node-Metastasis Stage 1B (T1B, N0, M0) grade III status post-right partial nephrectomy. Computed tomography (CT) imaging revealed a soft-tissue mass, suspected to be metastasis, in the left lobe of the thyroid, in addition to a 1.9 cm right intracranial mass in the parietal lobe. Positron emission tomography/computed tomography revealed a hypermetabolic area in the thyroid. Fine needle aspiration of the thyroid, and subsequent histopathological analysis, suggested a diagnosis of RCC metastasis. Subsequent immunohistochemical analysis of the thyroid tumor confirmed RCC metastasis. The patient also underwent a right partial craniotomy with resection of the intra-axial mass. Initial pathology was suggestive of an AVM. After several months, the patient was readmitted with headache, nausea and vomiting. Repeat imaging revealed recurrence of a 3.9 cm mass that was negative for AVM on biopsy; however, the immunostaining markers were positive for RCC. Recent literature suggests a link between AVMs and RCC as each exhibit highly vascular characteristics. RCC is a particularly vascular tumor that has been demonstrated to lead to the abnormal expression of various angiogenesis-promoting growth factors, including vascular endothelial growth factor. These angiogenic factors

Between June 2000 and June 2013, 179 patients with chondrosarcoma in the extremities were treated at eleven hospitals. Twenty consecutive patients (11.2% developed lung metastases after initial treatment of primary chondrosarcoma in the extremities. We investigated the oncological outcome of 20 chondrosarcoma patients with lung metastasis. There were 14 males and six females with a mean age of 49 years. The mean duration between primary surgery and appearance of lung metastases was 34 months. The mean follow-up period was 48 months. We excluded patients with lung metastasis at the time of presentation from this study. At the final follow-up, four of 20 patients had no evidence of disease, four were alive with disease, and twelve had died of disease. The

    Renal cell carcinoma (RCC) is commonly known as the "internist's tumor" because of its unpredictable behavior. Metastasis to the thyroid gland is rarely found in clinical practice. We report a rare case of non-thyroid malignancies NTM from renal cell carcinoma 1.5 years after radical nephrectomy in a 58-year-old man with a rapidly growing neck mass. Malignant melanoma, breast carcinoma, lung, and skin cancer are the most common sources of non-thyroid malignancies (NTM). Although metastases of NTMs to the thyroid gland are uncommon in clinical practice, it should be considered in patients with a history of prior malignancy and a new thyroid mass. Isolated thyroid metastasis should be considered in patients with a previous history of cancer and newly developing thyroid mass. Copyright © 2014 The Authors. Published by Elsevier Ltd..

    Full Text Available Introduction. Hepatocellular carcinoma (HCC is the most frequent primary malignant tumor of the liver. It is usually seen in the 6th and 7th decades of life and chronic hepatitis B is the most frequent cause. Extrahepatic metastasis of HCC is an indicator of a poor prognosis and the most common sites are lungs, bones, lymph nodes, kidneys and adrenal glands. We reported a case of isolated metastasis in the right maxilla, which had been found initially, before the tumor in the liver was diagnosed. Case report. A 70-year-old man underwent dental surgery of the upper right molar. Prolonged bleeding control was difficult for up to two weeks, so the biopsy was performed. Histopathological analysis revealed a metastatic hepatocellular carcinoma. Computerized tomography (CT of the abdomen revealed a diffusely heterogeneous liver parenchyma with irregular borders and two foci of mass lesions. There were metastasis in the spleen and also two pathological retroperitoneal lymph nodes were detected, but no ascit, liver cirrhosis, cholestasis or portal vein thrombosis were seen. CT of the orbital and maxillary regions revealed a tumor mass in the right maxillary sinus, spreading to the alveolar sinus, nasal cavity and partially infratemporal space. A tumor mass was in the right orbit as well, infiltrating the surrounding bones and muscles. Clinically, there was proptosis of the right eye accompanied by amaurosis. The treatment started with chemotherapy based on 5-fluorouracil (sorafenib was not available. After three cycles, control CTs showed a stable disease in the liver, but progression in the right maxillary sinus and orbit. Enucleation of the right eye was performed and postoperative radiotherapy was planed. The patient deteriorated rapidly and died, about 6 months after the disease had been diagnosed. Conclusion. Extrahepatic metastasis of HCC represents a progressive phase of the disease with poor prognosis, so the main aim of the treatment should be

    Full Text Available Background: Mammary analogue secretory carcinoma (MASC is a pathological entity arising in the salivary glands first described by Skalova et al. [Am J Surg Pathol 2010;34: 599–608]. Here, we report the first case of MASC presenting as a cervical lymph node metastasis of unknown primary site together with a brief review of the literature. Case Report: We present a 74-year-old male with a painless lump in his left neck. Based on the fine-needle aspiration cytological findings, a possible malignant tumor was suspected. No evidence of a primary lesion was observed using imaging modalities including positron emission tomography/computed tomography. The patient underwent an ipsilateral modified radical neck dissection. Immunohistochemical staining showed that the neoplastic cells were positive for S100 protein and GATA3. A rearrangement of the ETV6 gene was noted during fluorescence in situ hybridization, and the final histopathological diagnosis was MASC. Conclusion: We encountered a MASC presenting as a cervical lymph node metastasis of unknown primary site. No adjuvant therapy was administered, and no local recurrence or metastatic disease has been detected during a follow-up period of 9 months. This is the first case report of MASC presenting as a cervical lymph node metastasis of unknown primary site and suggests the new properties of MASC.

    Optogenetics is currently one of the most popular technique in neuroscience. It enables cell-selective and temporally-precise control of neuronal activity. Good spatial control of the stimulated area and minimized tissue damage requires a specific knowledge about light scattering properties. Light propagation in cell cultures and brain tissue is relatively well documented and allows for a precise and reliable delivery of light to the neurons. In spinal cord, light must pass through highly organized white matter before reaching cell bodies present in grey matter, this heterogenous structure makes it difficult to predict the propagation pattern. In this work we investigate the light distribution properties through mouse and monkey spinal cord. The light propagation depends on a fibers orientation, leading to less deep penetration profile in the direction perpendicular to the fibers and lower attenuation in the direction parallel to the fibers. Additionally, the use of different illumination wavelengths results in variations of the attenuation coefficient. Next, we use Monte-Carlo simulation to study light transport. The model gives a full 3-D simulation of light distribution in spinal cord and takes into account different scattering properties related to the fibers orientation. These studies are important to estimate the minimum optical irradiance required at the fiber tip to effectively excite the optogenetic proteins in a desired region of spinal cord.

    Metastasis is the leading cause of most cancer deaths, as opposed to dysregulated cell growth of the primary tumor. Molecular mechanisms of metastasis have been studied for decades and the findings have evolved our understanding of the progression of malignancy. However, most of the molecular mechanisms fail to address the causes of cancer and its evolutionary origin, demonstrating an inability to find a solution for complete cure of cancer. After being a neglected area of tumor biology for quite some time, recently several studies have focused on the impact of the tumor microenvironment on cancer growth. The importance of the tumor microenvironment is gradually gaining attention, particularly from the perspective of biophysics. In vitro three-dimensional (3-D) metastatic models are an indispensable platform for investigating the tumor microenvironment, as they mimic the in vivo tumor tissue. In 3-D metastatic in vitro models, static factors such as the mechanical properties, biochemical factors, as well as dynamic factors such as cell-cell, cell-ECM interactions, and fluid shear stress can be studied quantitatively. With increasing focus on basic cancer research and drug development, the in vitro 3-D models offer unique advantages in fundamental and clinical biomedical studies.

    2012-05-01

    Vocal cord dysfunction (VCD) is a syndrome characterized by the intermittent, abnormal paradoxical adduction of the true vocal cords during respiration resulting in variable upper airway obstruction. It is also commonly referred to as paradoxical vocal fold motion disorder. Patients with VCD usually present with intermittent shortness of breath of varying intensity, wheezing, stridor, choking, throat tightness, voice changes, or cough, and these symptoms often resolve quickly after relaxation or cessation of activity. Since first described as a distinct clinical entity in 1983, VCD remains underrecognized and the underlying cause(s) is not fully understood. Several studies suggest psychogenic or laryngeal hyperresponsiveness as possible underlying causes. Although VCD may have many causes, it can be a unique problem, especially in athletes because it often mimics and can be easily mistaken for exercise-induced bronchospasm, which may result in unnecessary medical treatment and delay in diagnosis. A detailed history, physical examination, and pulmonary function tests with flow-volume loops are important for excluding other diagnoses; however, the gold standard method for diagnosing VCD is by observation of the vocal cords with flexible laryngoscopy. The mainstay of treatment includes behavioral management guided by a speech-language pathologist, but optimal therapy often requires a multidisciplinary team involving a variety of specialties, including certified athletic training, pulmonology, otolaryngology, speech-language pathology, gastroenterology, allergy and immunology, and psychology, as appropriate. We reviewed the medical literature for VCD specifically in athletes, and this article discusses in detail the definition, epidemiology, possible pathophysiology, diagnosis, and treatment options.

    Full Text Available This paper reports a case of nonpapillary and infiltrative transitional cell carcinoma (TCC of the urinary bladder with metastasis of lumbar vertebrae and spinal cord compression in an adult female ocelot (Leopardus pardalis, from the Mato Grosso state, Brazil. The ocelot had pelvic limb paralysis and skin ulcers in the posterior region of the body and was submitted to euthanasia procedure. At necropsy was observed a multilobulated and irregular shaped, yellowish to white nodule in the urinary bladder. The nodule had a soft consistency and arised from the mucosa of the urinary bladder extending throughout the muscular layers and the serosa. Nodules of similar appearance infiltrating the vertebral column the at L6 and L7 vertebrae with corresponding spinal canal invasion were also observed. The histological evaluation showed epithelial neoplastic proliferation in the urinary bladder with characteristics of nonpapillary and infiltrative TCC, with positive immunohistochemical staining for pancytokeratin, and strong immunostaining for cytokeratin of low molecular weight, and weak or absent labeling for high molecular weight cytokeratin. This is the first report of TCC of urinary bladder in ocelot in Brazil.

    2013-01-01

    Full Text Available Introduction. Follicular thyroid carcinoma (FTC frequently metastasizes to the lungs and bones. However, metastasis to the skeletal muscles is an extremely rare manifestation of FTC. To date, only seven cases of FTC have been reported in the literature. Skeletal muscle metastases from FTC usually remain asymptomatic or manifest as swelling and are associated with dismal prognosis. Case Presentation. A 45-year-old Saudi woman presented with right buttock swelling since 8 months. Physical examination revealed right gluteal mass of size  cm and right thyroid lobe nodule. The rest of examination was unremarkable. Magnetic resonance imaging (MRI showed  cm lobulated mass arising from the gluteus medius muscle, and tru-cut biopsy confirmed the metastatic papillary carcinoma of thyroid origin. The patient subsequently underwent palliative radiotherapy followed by total thyroidectomy and radioactive iodine ablation. At the time of publication, the patient was alive with partial response in gluteal mass. Conclusion. Skeletal muscles metastases are a rare manifestation of FTC, and searching for the primary focus in a patient with skeletal muscle metastasis, thyroid cancer should be considered as differential diagnosis.

    Children with spina bifida occulta require early surgery to prevent neurological deficits. The treatment of patients with a congenitally tethered cord who present in adulthood remains controversial. The authors studied the medical records of 61 adult patients who underwent surgical untethering for spina bifida occulta at three institutions between 1994 and 2003. Patients who had undergone prior myelomeningocele repair or tethered cord release surgery were excluded. The most common intraoperative findings were lipomyelomeningocele (41%) and a tight terminal filum (36%). The follow-up duration ranged from 10.8 to 149.5 months. Of the 34 patients with back pain, status improved in 65%, worsened in 3%, remained unchanged in 18%, and improved and later recurred in 15%. Lower-extremity pain improved in 16 patients (53%), remained unchanged in 23%, improved and then recurred in 17%, and worsened in 7%. Lower-extremity weakness improved in 47%, remained unchanged in 47%, and improved and then recurred in 5%. Finally, of the 17 patients with lower-extremity sensory changes, status improved in 35%, remained unchanged in 35%, and the information on five patients was unavailable. Surgical complications included three wound infections, one cerebrospinal fluid leak, and two pseudomeningoceles requiring surgical revision. One patient developed acute respiratory distress syndrome and sepsis postoperatively and died several days later. Adult-age presentation of a congenital tethered cord is unusual. Despite a slight increase in postoperative neurological injury in adults, surgery has relatively low risk and offers good potential for neurological improvement or stabilization. As they do in children, the authors recommend early surgery in adults with this disorder. The decision to undertake surgery, however, should be modulated by other factors such as a patient's general medical condition and risk posed by anesthesia.

    Full Text Available Background: Neuralgic amyotrophy (brachial plexus neuropathy, brachial plexus neuritis, or Parsonage-Turner syndrome is an uncommon inflammatory condition typically characterized by acute and severe shoulder pain followed by paresis with muscle weakness and atrophy of the upper limb or shoulder girdle. We report an unusual clinical manifestation of neuralgic amyotrophy, namely bilateral phrenic nerve palsy with concomitant laryngeal paresis. Case Report: A 55-year-old male presented with orthopnea and aphonia after an episode of bilateral shoulder pain preceded by an upper respiratory tract infection. Spirometry, chest X-ray and videolaryngoscopy revealed bilateral and simultaneous paresis of the diaphragm and the vocal cords. Clinical examination at admission and at the 2-month follow-up did not show upper limb weakness or atrophy, except for a mild atrophy of the right supraspinatus muscle. An electromyography of the upper limb muscles and nerve conduction studies did not reveal signs of denervation. Analysis of the cerebrospinal fluid and an MRI of the neuraxis were unremarkable. After treatment with prednisolone, vocal cord function markedly improved within 8 weeks, whereas paresis of the diaphragm persisted. Conclusion: Shoulder pain followed by diaphragmatic paralysis with dyspnea and hoarseness may be a manifestation of neuralgic amyotrophy even if upper limb or shoulder girdle palsies are absent.

    2016-10-01

    Univariate and multivariate relationships between perfectionistic self-presentation and reactions to impairment and disability following spinal cord injury were examined. A total of 144 adults with spinal cord injury ( M = 48.18 years old, SD = 15.96) completed self-report measures. Analyses revealed that, after controlling for time since injury and gender, perfectionistic self-presentation predicted six of eight reactions, shock, depression and internalised anger particularly strongly. In addition, at multivariate level, perfectionistic self-presentation was positively related to non-adaptive reactions and negatively related to adaptive reactions. The findings suggest that perfectionistic self-presentation may contribute to poorer psychosocial adaptation to spinal cord injury.

    2015-01-01

    Full Text Available Adenoid cystic carcinoma (ACC is a rare neoplasm that usually arises from minor salivary glands. It is characteristically locally infiltrative, exhibiting perineural invasion, has a tendency for local recurrence and prolonged clinical course. A 60 year old male, chronic smoker presented with swelling of the left cervical lymph node since two months. Examination revealed a solitary firm, non tender, non mobile left cervical swelling measuring 2 x 1 cm. Fine Needle Aspiration Cytology (FNAC was done from the cervical lymph node. The diagnosis of metastatic deposits of ACC was given. Detail examination of the oral cavity revealed a small swelling at the floor of the mouth. Biopsy of the swelling confirmed ACC on histopathological examination. An unusual feature of adenoid cystic carcinoma is the low incidence of metastases to regional lymph nodes. The case is presented to highlight its unusual presentation and utility of FNAC in rapid diagnosis.

    Full Text Available Postoperative C5 palsy (C5 palsy is a troublesome complication after cervical spine surgery and its etiology is still unclear. We experienced a case of C5 palsy after anterior decompression with fusion for cervical ossification of posterior longitudinal ligament with the typical clinical presentation of left deltoid and bicep weakness and left-arm pain without deterioration of myelopathy symptoms, albeit with the unusual imaging findings not shown preoperatively of a swelling in the spinal cord, and intramedullary high intensity change on T2-weighed MRI. The additional posterior surgery was carried out to decompress the swollen spinal cord. The abnormal findings disappear on MRI taken three weeks following the second surgery and the weakness improved fully within three months after the second surgery. This case report highlights the possibility of spinal cord lesion due to circulatory impairment as a cause of C5 palsy.

    Directory of Open Access Journals (Sweden)

    Shotaro Kanda

    2015-01-01

    Full Text Available Adult tethered cord syndrome (ATCS is a rare entity that usually presents with multiple neurological symptoms, including lower extremity pain, backache, lower extremity muscle weakness, and bowel/bladder disturbances. Prompt surgical treatment is often necessary to avoid permanent sequelae. We report a 63-year-old man with sudden-onset severe right chest and upper back pain, followed by urinary retention. His initial workup included computed tomography of the abdomen and pelvis, which showed a presacral mass. His symptom-driven neurological workup focused on the cervical and thoracic spine, the results of which were normal. Pelvic radiographs and magnetic resonance imaging of the lumbosacral spine showed spina bifida occulta, meningocele, and presacral masses consistent with a teratomatous tumor. His symptoms, except for urinary retention, improved dramatically with surgical treatment. The excised specimen contained a teratomatous lesion plus an organized hematoma. Hematoma formation was suspected as the trigger of his sudden-onset right chest and upper back pain.

    Full Text Available Background. MSA (Multiple System Atrophy may be associated either with Parkinsonism or with cerebellar ataxia (MSA-c subtype. It is considered a rare disease, but many patients are misdiagnosed as suffering from idiopathic Parkinson's disease. In this paper, we report a case of a patient admitted with respiratory failure and vocal cords paralysis due to MSA-c. Case Report. A 79-year-old Caucasian woman was admitted in March 2010 with dyspnea, asthenia, stridor, and respiratory failure needing noninvasive ventilation. She had orthostatic blood pressure decline, constipation, insomnia, daytime sleepiness, and snoring. The neurologic examination revealed cerebellar ataxia. A laryngoscopy revealed vocal cord paralysis in midline position and tracheostomy was performed. The Brain Magnetic Resonance Imaging revealed atrophy of middle cerebellar peduncles and pons with the “hot cross bun sign.” Conclusion. Although Multiple-system atrophy is a rare disease, unexplained respiratory failure, bilateral vocal cord paralysis, or stridor should lead to consider MSA as diagnosis.

    Umbilical cord blood (UCB), previously seen as medical waste, is increasingly recognized as a valuable source of cells for therapeutic use. The best-known application is in hematopoietic stem cell transplantation (HSCT), where UCB has become an increasingly important graft source in the 28 years since the first umbilical cord blood transplantation (UCBT) was performed. Recently, UCB has been increasingly investigated as a putative source for adoptive cell therapy. Areas covered: This review covers the advances in umbilical cord blood transplantation (UCBT) to overcome the limitation regarding cellular dose, immunological naivety and additional cell doses such as DLI. It also provides an overview regarding the progress in adoptive cellular therapy using UCB. Expert opinion: UCB has been established as an important source of stem cells for HSCT. Successful strategies to overcome the limitations of UCBT, such as the limited cell numbers and naivety of the cells, are being developed, including novel methods to perform in vitro expansion of progenitor cells, and to improve their homing to the bone marrow. Promising early clinical trials of adoptive therapies with UCB cells, including non-immunological cells, are currently performed for viral infections, malignant diseases and in regenerative medicine.

    Full Text Available Endometrial cancer is the most common gynecologic malignancy in the United States. However, bony metastasis is infrequent and exceptionally rare as the initial presentation. We report a case of a 77-year-old female with a clinically silent endometrial carcinoma who presented with a left tibial metastasis as the first manifestation of her disease. Ours is only the third case diagnosed by fine-needle aspiration (FNA cytology, and the first to detail the cytomorphologic features of metastatic endometrial cancer to bone. These microscopic findings, including three-dimensional cohesive clusters with cellular overlapping and cuboidal to columnar cells exhibiting low nuclear: cytoplasmic ratios and partially vacuolated cytoplasm, differ significantly from those of endometrial carcinoma on a Papanicolaou test. The tumor bore similarity to the more commonly encountered metastatic colon cancer, but immunohistochemical staining enabled reliable distinction between these entities. A review of osseous metastases of endometrial cancer demonstrates a predilection for bones of the lower extremity and pelvis with a predominance of the endometrioid histologic subtype. In about a quarter of the cases, the bony metastasis was the first manifestation of the cancer. FNA was an effective diagnostic modality for this unusual presentation of a common malignancy. Awareness of this entity and its differential diagnosis is essential for accurate and timely diagnosis.

    Tolerance of the spinal cord to the single dose of radiation is not well defined. Although there are cases of human spinal cord tolerance from re-irradiation to the same cord level, the information about the tolerance of human spinal cord to single large dose of radiosurgery is not available. We carried out spinal radiosurgery to treat spinal metastasis and studied the single dose tolerance of the human spinal cord in an ongoing dose escalation paradigm. A total of 39 patients with 48 lesions of spinal metastasis were treated with single dose radiosurgery at Henry Ford Hospital. The radiosurgery dose was escalated from 8 Gy to 16 Gy at 2 Gy increment. The radiation dose was prescribed to periphery of the spinal tumor. The radiation dose to the spinal cord was estimated by computerized dosimetry. The median follow-up time was 10 months (range 6-18 months) from the radiosurgery. The endpoint of the study was to demonstrate the efficacy of the spinal radiosurgery and to determine the tolerance of human spinal cord to single dose radiosurgery. The dose to the spinal cord was generally less than 50 % of the prescribed radiation dose. The volume of the spinal cord that received higher than this dose was less than 20 % of the anterior portion of the spinal cord. Maximum single dose of 8 Gy was delivered to the anterior 20 % of the spinal cord in this dose escalation study. The dose volume histogram will be presented. There was no acute or subacute radiation toxicity detected clinically and radiologically during the maximum follow-up of 20 months. Further dose escalation is in progress. The single tolerance dose of the human spinal cord appears to be at least 8 Gy when it was given to the 20 % of the cord volume, although the duration of follow up is not long enough to detect severe late cord toxicity. This study offers a valuable radiobiological basis of the normal spinal cord tolerance, and opens spinal radiosurgery as a safe treatment for spinal metastasis

    Full Text Available Gastric cancer can have protean manifestations, usual symptoms mimicking those of peptic ulcer disease. Gastric adenocarcinomas have rarely been reported with leptomeningeal carcinomatosis (LMC and dermatoses as initial presenting features. It is also difficult to diagnose breast metastasis of gastric carcinoma due to its rarity. We report two such cases with rare initial presentation. Our first case was a 46-year-old male who presented with LMC. Our second case was a 24-year-old male whose initial complaints were shortness of breath, bilateral breast lumps, and skin discoloration. Both cases on further investigations were found to have primary tumors in the stomach.

    The present study was performed to clarify the clinical characteristics of brain metastasis from colorectal cancer. Five patients with brain metastasis from colorectal cancer treated at our institute between 2001 and 2005 were included in the study. Clinical findings and survival time were determined and an appropriate system for follow-up in such cases was considered. Brain metastasis was found after surgery for colorectal cancer in 4 cases. In addition, colorectal cancer was found after diagnosis of brain metastasis in 1 case. At the time of diagnosis of brain metastasis, all patients had lung metastasis and 3 had liver metastasis. The mean periods between surgery for colorectal cancer and lung and brain metastases were 19.5 and 38.2 months, respectively. In all cases, brain metastasis was diagnosed by imaging after the appearance of neurological symptoms. Brain metastases were multiple in 1 case and focal in 4 cases. We performed gamma knife radiation therapy, and the symptoms disappeared or decreased in all cases. Mean survival time after brain metastasis was 3.0 months. Prognosis after brain metastasis is poor, but gamma knife radiation therapy contributed to patients' quality of life. (author)

    The objective of the present study was to evaluate the influence of non-invasive (transcutaneous) electrical spinal cord stimulation on the locomotor function of the patients suffering from movement disorders. The study involved 10 patients of both sexes at the age from 32 to 70 years (including 40% of men and 60% of women) presenting with the compromised locomotor function of varying severity associated with the disturbances of cerebral blood circulation caused either by an injury to the brain and spinal cord or by stroke. The transcutaneous electrical spinal cord stimulation was applied using different frequency regimes with the placement of the electrodes in the projection onto the region of TXI-TXII vertebrae. The active factors were bipolar electrical stimuli 0.5 ms in duration; the current strength was chosen for each patient on an individual basis taking into consideration its threshold level. Electromyograms and evoked motor responses of selected muscles, viz. m. rectus femoris, m.biceps femoris, m. tibialis anterior, and m.gastrocnemius were recorded with the use of the 'Neuro-MVP-8 eight-channel electromyography' ('Neurosoft', Russia). The data obtained give evidence that the stimulation of the spinal cord with a frequency of 1 Hz induces reflectory responses with monosynaptic and polysynaptic components in the muscles of the lower extremities, with the thresholds of these responses being significantly higher in the patients presenting with serious neurological problems. Stimulation with the frequencies of 5 and 30 Hz caused in the patients with paresis the involuntary movement of the legs the characteristics of which were similar to those of the locomotor movements. It has been demonstrated that the application of transcutaneous electrical spinal cord stimulation leads to increased excitability of the lumbar spinal neural structures of the patients. The study has shown the possibility of regulation of the locomotor functions in the patients presenting

    Radiation-related sarcoma is a rare but serious complication for patients after receiving radiation therapy initially for their primary malignancy. However, it usually takes several years and needs enough in-field radiation dose to develop this sarcoma. We describe a 60-year-old man with right axillary sarcoma revealed by whole-body F-FDG PET/CT 1 year after chemoradiotherapy, which presented ultrashort latency period and did not match the consensus definition of radiation-related sarcoma. Besides, metastatic sarcoma to small intestine was accidentally noted in the F-FDG PET/CT image.

    2011-11-01

    Most isolated abducens (sixth) nerve palsies are ischaemic in nature. However, there are other causes that can mimic an abducens nerve palsy, which requires aggressive diagnostic management. A 56-year-old hypertensive woman presented with a right abduction deficit. Her past history revealed that she had undergone a mastectomy and completed a course of chemo- and radiation therapy for breast carcinoma. She was well until she develped binocular diplopia five months later. Magnetic resonance imaging showed a right pontine mass. Stereotactic biopsy was performed, and histopathology revealed a metastatic carcinoma that was compatible with an origin from the breast primary. We conclude that identifying and managing patients with metastatic lesions involves a multidisciplinary approach. Thorough history-taking and neuro-ophthalmologic evaluation would help physicians in establishing the primary differentials, which could not only be sight-saving but life-saving as well.

    Full Text Available Spinal cord tumors are a rare neoplasm of the central nervous system (CNS. The occurrence of metastases is related to poor prognosis. The authors analyzed one series of metastasis cases and their associated mortality. METHODS: Clinical characteristics were studied in six patients with intramedullary tumors with metastases in a series of 71 surgical cases. RESULTS: Five patients had ependymomas of which two were WHO grade III. The patient with astrocytoma had a grade II histopathological classification. Two patients required shunts for hydrocephalus. The survival curve showed a higher mortality than the general group of patients with no metastases in the CNS (pTumores da medula espinhal são neoplasias raras do sistema nervoso central (SNC. A ocorrência de metástases é relacionada a pior prognóstico. Os autores analisaram uma série de casos de metástases e a mortalidade relacionada. MÉTODO: Foram estudadas as características clínicas em seis pacientes com metástases tumorais numa série de 71 casos operados. RESULTADOS: Cinco pacientes tinham ependimomas e dois dos quais foram grau III pela classificação da OMS. O paciente portador de astrocitoma tinha classificação histopatológica de grau II. Dois pacientes necessitaram de derivação devido à hidrocefalia. A curva de sobrevivência mostrou mortalidade mais elevada no grupo de pacientes com disseminação pelo SNC (p<0,0001. CONCLUSÃO: A mortalidade, além de elevada em pacientes com metástases, é maior do que em pacientes apenas com lesão primária. Os ependimomas, independentemente do seu grau de anaplasia, costumam causar mais metástases do que os astrocitomas medulares.

    Vocal cord dysfunction involves inappropriate vocal cord motion that produces partial airway obstruction. Patients may present with respiratory distress that is often mistakenly diagnosed as asthma. Exercise, psychological conditions, airborne irritants, rhinosinusitis, gastroesophageal reflux disease, or use of certain medications may trigger vocal cord dysfunction. The differential diagnosis includes asthma, angioedema, vocal cord tumors, and vocal cord paralysis. Pulmonary function testing with a flow-volume loop and flexible laryngoscopy are valuable diagnostic tests for confirming vocal cord dysfunction. Treatment of acute episodes includes reassurance, breathing instruction, and use of a helium and oxygen mixture (heliox). Long-term management strategies include treatment for symptom triggers and speech therapy.

    This study aims to offer an accurate diagnosis for vocal cord nodules, polyps, and intraepithelial neoplasias through videolaryngostroboscopy (VLS) and multi-dimensional voice analysis program (MDVP) and to decide management modalities. A total of 397 patients (214 males, 183 females; mean age 46.2 years; range 17 to 71 years) with 218 nodules, 101 polyps and 78 vocal cord intraepithelial neoplasias who were admitted for treatment and follow-up in phoniatry unit of our clinic in the past five years were retrospectively analyzed in terms of VLS findings, the percent of jitter, percent of shimmer, fundamentally frequency, noise-harmonic ratio values, GRBAS [Grade of dysphonia (G), roughness (R), breathiness (B), asthenicity (A) and strain (S)] scores, and voice handicap index (VHI) obtained by MDVP. We obtained better voice parameters with improved GRBAS and SHE scores in patients with vocal cord nodules who underwent voice training and those with polyps who were operated, while these scores worsened following diagnostic phonosurgery in the intraepithelial group. In the initial examination, patients who are prediagnosed vocal cord nodules should have voice therapy as the first-line treatment modality and checked for the response to treatment. If laryngeal cancer is suspected, surgery should be planned according to the biopsy result and biopsy should be performed, if polyp is present.

    Less than twenty years ago, a high spinal cord injury accompanied by paralysis of the diaphragm and the resulting apnea and tetraplegia led to certain death within a short time after the trauma, mostly due to respiratory complications associated with ventilatory therapy in hospitals. The objective of this paper is to present the case of a paediatric brain stem trauma with spinal cord injury, consisting of spinal cord rupture in the upper cervical segment. Thanks to appropriate management at all treatment stages (prompt, fully professional assistance in the ambulance, followed by appropriate management at ICU), the child survived. Owing to currently available technical solutions, the boy has achieved considerable self-dependence and an opportunity of having post-traumatic complications treated using a diaphragm pacing stimulator and a baclofen pump. The report presents therapeutic problems encountered in children with post-traumatic spinal cord injury, emphasizing technical opportunities of managing diaphragm paralysis, as exemplified by the five-year treatment and rehabilitation process of a boy with spinal cord injury at C1 level managed at the University Children's Hospital of Cracow, Poland, in whom phrenic nerve stimulation was employed. The implanted stimulator and a specially constructed controller have allowed the boy to achieve mobility using a wheelchair, being able to use a PC and being taught by an individual teacher at home despite his tetraparesis. Recurrent respiratory tract infections and occasional decubitus required periodic hospitalizations. As the patient grew, in consequence of uncontrolled sudden increases of muscle tone of the trunk spine. Increased muscle tone was increasingly resistant to pharmacotherapy and negatively affected the effectiveness of home rehabilitation. In consequence, a decision was made to implant an intraspinal baclofen pump.

    Full Text Available A five-year-old male Boerboel presented for examination, collapsed for an unknown period of time. On clinical examination, multifocal subcutaneous masses and enlarged prescapular lymph nodes as well as neurological deficits that suggested a multifocal neurological syndrome were found. Fine needle aspirates of the prescapular lymph nodes revealed cells suggestive of osteosarcoma. Radiographs showed foci of mineralisation within the soft tissue masses as well as diffuse pulmonary metastasis and a caudodorsal mediastinal mass believed to be a Spirocerca lupi nodule. Computed tomography imaging, necropsy and histopathology confirmed S. lupi oesophageal neoplastic transformation (extraskeletal osteosarcoma, believed to be the primary lesion, and the majority of secondary metastasis to the brain, spine, heart, multiple muscular groups and abdominal organs. This is the first known report of extraskeletal osteosarcoma metastasis to the brain and spinal cord in a dog.

    In multiple system atrophy (MSA), sleep-related breathing disorders are commonly observed, including vocal cord abductor paralysis (VCAP), which can cause sudden death. In its early stage, VCAP occurs only during sleep, but as the disease progresses, it appears when both awake and asleep. We encountered a 59-year-old obese woman who had been under continuous positive airway pressure (CPAP) therapy for obstructive sleep apnea syndrome (OSAS) for approximately one year but later developed acute respiratory failure because of VCAP. VCAP was the predominant finding that led to the diagnosis of MSA in our patient. On laryngoscopic examination, the movement of the patient's larynx was normal during wakefulness, but VCAP, paradoxical movements of the vocal cord and a floppy arytenoid were observed during drug-induced sleep. We suggest that detection of VCAP and laryngopharyngeal abnormalities such as floppy arytenoid in the early stage of MSA is important for determining treatment options.

    Full Text Available Nasopharyngeal carcinoma (NPC is prevalent in Taiwan and is characterized by a high frequency of nodal metastasis. The most common organs with distal metastases are the bones, lungs, and liver, with extremely rare cases to the pericardium. Herein, we report a rare case with NPC who presented with dyspnea and orthopnea. Serial studies, including pericardial biopsy, revealed NPC with pericardial metastasis and pericardial effusion. The tumor cells of both the original and metastatic tumors were positive for Epstein–Barr virus by in situ hybridization. This is the first histologically confirmed case of NPC with pericardial metastasis.

    Full Text Available Carcinoma of the ampulla of Vater is a rare gastrointestinal tumor. Additionally, cutaneous metastasis from such an internal malignancy is also uncommon. We reported the case of a 55-year-old man afflicted with ampullary carcinoma with cutaneous metastasis. The patient did not undergo the standard Whipple procedure but received chemotherapy due to apparent left neck lymph node metastasis noted by initial PET/CT imaging. The skin metastasis presented as a left neck infiltrating purpuric lesion, which was confirmed by skin biopsy approximately one year after the patient's disease was first diagnosed. Thereafter, the patient received further chemotherapy pursuant to his course of medical management. Skin metastasis usually represents a poor patient prognosis. In these cases, treatment of cutaneous metastasis typically includes systemic chemotherapy and local management such as radiation therapy or tumor excision. And when choosing a chemotherapy regimen for the ampullary cancer, the histological subtypes (intestinal or pancreatobiliary should be comprehensively considered. In our review of the literature, the intestinal type seems to have less distant lymph node metastasis, advanced local invasion, as well as recurrence than pancreatobiliary type of ampullary cancer.

    A 38-year-old man was admitted to our hospital with neck pain, dysesthesia of both hands, and weakness of the left upper limb. He had been diagnosed with a chronic active Epstein-Barr virus infection (CAEBV) at the age of 34 and had undergone umbilical cord blood transplantation at the age of 37. MRI of the spinal cord revealed an intramedullary hyperintense lesion on T₂-weighted images with gadolinium enhancement. Because his laboratory tests revealed proliferation of CD19(+) lymphocytes in the peripheral blood, and EBV DNA was detected in both peripheral blood and CSF, he was diagnosed as having post-transplant EBV associated lymphoproliferative disease. However, chemotherapy did not alleviate his symptoms. At a later time, quantitative chimerism analysis of his CSF showed a higher proportion of lymphocytes that had originated from the recipient. Finally, he was diagnosed as having a recurrence of CAEBV in the central nervous system, and his symptoms were restored by intrathecal chemotherapy (methotrexate, cytosine arabinoside, and prednisolone). Quantitative chimerism analysis of CSF was useful for diagnosing the recurrence of CAEBV in the central nervous system.

    2013-01-01

    Full Text Available Background. Longitudinally extensive transverse myelitis (LETM is characterized by spinal cord inflammation extending vertically through three or more vertebral segments. The widespread use of MRI revealed LETM more frequency than ever. We report the case of a patient with pathologically confirmed small-cell lung carcinoma metastasis into the spinal cord presenting as LETM. Case Presentation. A 74-year-old man developed rapidly progressive sensorimotor disturbance and vesicorectal dysfunction. T2-weighted magnetic resonance imaging of the spine revealed LETM at the level of from T3 to conus medullaris; gadolinium enhancement showed concurrent tumor in the thoracic spinal cord from T10 to T11. Systemic survey identified a nodular mass in the lung that was verified as small-cell carcinoma. Following initial failed treatment by high-dose steroid, the patient underwent an emergent microsurgical tumor resection. Histological examination was identical with the lung carcinoma. The patient died of tumor progression at the 47th day after admission. At autopsy, only changes of edema were found in the gray matter of the cord, while tumor cells were not noted in it. Conclusion. Metastasis may rarely present symptoms of LETM. Prompt identification of underlying etiology by contrast examination and systemic survey is crucial for the patient assumed as LETM.

    Full Text Available Abstract Introduction We report on a very rare case of a cervical ligamentum flavum cyst, which presented with progressive myelopathy and radiculopathy. The cyst was radically extirpated and our patient showed significant recovery. A review of the relevant literature yielded seven cases. Case presentation An 82-year-old Greek woman presented with progressive bilateral weakness of her upper extremities and causalgia, cervical pain, episodes of upper extremity numbness and significant walking difficulties. Her neurological examination showed diffusely decreased motor strength in both her upper and lower extremities. Magnetic resonance imaging of her cervical spine demonstrated a large, well-demarcated cystic lesion on the dorsal aspect of her spinal cord at the C3 to C4 level, significantly compressing the spinal cord at this level, in close proximity to the yellow ligament and the C3 left lamina. The largest diameter of this lesion was 1.4 cm, and there was no lesion enhancement after the intravenous administration of a paramagnetic contrast. The lesion was surgically removed after a bilateral C3 laminectomy. The thick cystic wall was yellow and fibro-elastic in consistency, while its content was gelatinous and yellow-brownish. A postoperative cervical-spine magnetic resonance image was obtained before her discharge, demonstrating decompression of her spinal cord and dural expansion. Her six-month follow-up evaluation revealed complete resolution of her walking difficulties, improvement in the muscle strength of her arms (4+/5 in all the affected muscle groups, no causalgia and a significant decrease in her preoperative upper extremity numbness. Conclusion Cervical ligamentum flavum cysts are rare benign lesions, which should be included in the list of differential diagnosis of spinal cystic lesions. They can be differentiated from other intracanalicular lesions by their hypointense appearance on T1-weighted and hyperintense appearance on T2

    Pulsatile longitudinal motion of the spinal cord was examined with MR phase imaging in healthy subjects and in cases involving cord tethering and compression. Asymptomatic patients with a low conus medullaris demonstrated normal cord motion. Clinical improvement was associated with improved cord motion after surgical untethering, provided permanent neurologic damage had not occurred. Decreased and unchanged cord motion was associated with unchanged neurologic deficits. In cases of normal cord motion and possible retethering versus syringomyelia, clinical improvement occurred after shunting only. MR imaging of pulsatile cord motion can be clinically useful in the evaluation of diseases restricting motion of the neuraxis

    Tectal gliomas (TG) are slow-growing tumors and generally present with features of increased intracranial pressure. We describe an unusual case of a young girl who presented with clinical triad of obesity, primary amenorrhea and central cord syndrome. The radiology unveiled a pentad of hydrocephalus, empty sella, suprapineal recess diverticulum, secondary Chiari malformation and cervical syringomyelia, masking a relatively obscure tectal plate glioma. She was subjected to endoscopic third ventriculostomy (ETV). All of her symptoms improved after ETV and the tumor is being followed up. The possible pathogenesis of such a highly atypical clinico-radiological presentation is described. This unusual syndromic presentation of tectal glioma without clinical features of increased intracranial pressure is probably due to increased compliance of third ventricular walls, and is relieved with ETV.

    Results: Most of the patients were in the age group of 41–60 years and there was no gender preponderance in patients. Female breast cancer was the most common incident (15.5% malignancy followed by multiple myeloma, lung, and prostatic carcinoma. Lower dorsal spine was the most common site of compression (35% followed by lumbar (31% and mid-dorsal (26% spine. 70 (91% patients had cord compression subsequent to bone metastasis while as other patients had leptomeningeal metastasis. In 31 (40% patients, spinal cord compression was the presenting symptom. Overall, only 26 patients had motor improvement after treatment. Conclusion: Grade of power before treatment was predictive of response to treatment and overall outcome of motor or sensory functions. Neurodeficit of more than 10 days duration was associated with poor outcome in neurological function.

    Metastasis accounts for the vast majority of morbidity and mortality associated with melanoma. Evidence suggests melanoma has a predilection for metastasis to particular organs. Experimental analyses have begun to shed light on the mechanisms regulating melanoma metastasis and organ specificity, but these analyses are complicated by observations of metastatic dormancy and dissemination of melanocytes that are not yet fully malignant. Additionally, tumor extrinsic factors in the microenvironment, both at the site of the primary tumor and the site of metastasis, play important roles in mediating the metastatic process. As metastasis research moves forward, paradigms explaining melanoma metastasis as a step-wise process must also reflect the temporal complexity and heterogeneity in progression of this disease. Genetic drivers of melanoma as well as extrinsic regulators of disease spread, particularly those that mediate metastasis to specific organs, must also be incorporated into newer models of melanoma metastasis.

    Full Text Available Oral cavity is a rare target for metastasis with an incidence of 1% among all oral cancers. In 24% of such cases, oral metastasis is the first indication of an undiagnosed primary. Metastatic oral malignancies have been reported in the mandible, tongue, and gingiva. Although gingival metastasis has been reported from lung, prostate, rectal carcinoma in men and carcinoma of breast, adrenal glands, and genitalia in females, gingival metastasis from carcinoma of the penis has not been reported. Herein, a case of metastatic gingival carcinoma that developed after extraction of teeth from primary carcinoma of the penis is presented. An extensive literature search revealed no such similar case reports.

The first miR-driven network orchestrating invasion, intravasation, and metastasis was confirmed independently across several malignancies, suggesting a rather general principle for metastasis regulation. We hope that our data will stimulate the field in terms of further hypothesis generation, metastasis prediction, and metastasis prevention.

    Differential diagnosis between spinal metastasis and infectious spondylodiscitis is one of the occasional challenges in daily clinical practice. We encountered an unusual case of spinal metastasis in a 75-year-old female breast cancer patient that mimicked infectious spondylodiscitis. Magnetic resonance imaging (MRI) showed diffuse bone marrow infiltrations with paraspinal soft tissue infiltrative changes in 5 contiguous cervical vertebrae without significant compression fracture or cortical destruction. These MRI findings made it difficult to differentiate between spinal metastasis and infectious spondylodiscitis. Infectious spondylodiscitis such as tuberculous spondylodiscitis was regarded as the more appropriate diagnosis due to the continuous involvement of > 5 cervical vertebrae. The patient's clinical presentation also supported the presumptive diagnosis of infectious spondylodiscitis rather than spinal metastasis. Intravenous antibiotics were administered, but clinical symptoms worsened despite treatment. After pathologic confirmation by computed tomography-guided biopsy, we were able to confirm a final diagnosis of spinal metastasis

    Information on referred pain can be helpful for diagnosing diseases of the visceral organs. Here, the authors report a patient with cervical spinal cord injury (SCI) who had referred pain at the right side from the neck to shoulder, as a presentation of pulmonary embolism (PE). A 55-year-old man with complete tetraplegia, due to cervical SCI after C5 and C6 vertebral body fracture, complained of right neck-to-shoulder pain (numerical scale rating: 6). Despite pain medication (meloxicam 15 mg, gabapentin 400 mg, and propacetamol HCl 1 g), the pain was not reduced. Along with right neck-to-shoulder pain, he presented mild fever (37.8°C) and mildly elevated respiratory rate (20 breaths/min). D-dimer level was also mildly elevated to 6.09 mg/mL (normal value: pain completely disappeared. This study shows that pain at the neck-to-shoulder area can occur following unexpected causes such as PE. Not limited to PE, the evaluation of diseases in the thoracic or abdominal organs is recommended if patients with cervical SCI present refractory pain in the dermatomes innervated by high cervical nerve roots.

    The present is an overview of recent data that describes the genetic underpinnings of the suppression of cancer metastasis. Despite the explosion of new information about the genetics of cancer, only six human genes have thus far been shown to suppress metastasis functionally. Not all have been shown to be functional in breast carcinoma. Several additional genes inhibit various steps of the metastatic cascade, but do not necessarily block metastasis when tested using in vivo assays. The implications of this are discussed. Two recently discovered metastasis suppressor genes block proliferation of tumor cells at a secondary site, offering a new target for therapeutic intervention

    2017-01-01

    Full Text Available Chordomas are rare malignant tumors of notochordal origin and are rare locally aggressive ones with a metastatic potential. The skin rarely is seen as metastatic site. We describe a case of an adult woman with cutaneous metastasis of a primary sacral chordoma excised ten years before, which appeared as a painless cutaneous mass located in the dorsal region. Once removed, the surgical specimen was formalin fixed and in paraffin embedded. Sections were stained with haematoxylin-eosin, and histochemical and immunohistochemical investigations were performed. Histologically, the neoplasia was characterized by cords or single tumor cells with an abundant myxoid stroma, conspicuous pale vacuolated cytoplasm (the classic “physaliphorous cells”, and mild nuclear atypia. Mitotic activity was scanty. At immunohistochemistry, the tumor cells were diffusely positive for S-100 protein, pan-keratins, EMA, and vimentin. A diagnosis of cutaneous metastasis of chordoma was performed. This case illustrates a diagnostic challenge because of the unusual presentation of an already rare tumor.

    Full Text Available   Stem cells are naïve or master cells. This means they can transform into special 200 cell types as needed by body, and each of these cells has just one function. Stem cells are found in many parts of the human body, although some sources have richer concentrations than others. Some excellent sources of stem cells, such as bone marrow, peripheral blood, cord blood, other tissue stem cells and human embryos, which last one are controversial and their use can be illegal in some countries. Cord blood is a sample of blood taken from a newborn baby's umbilical cord. It is a rich source of stem cells, umbilical cord blood and tissue are collected from material that normally has no use following a child’s birth. Umbilical cord blood and tissue cells are rich sources of stem cells, which have been used in the treatment of over 80 diseases including leukemia, lymphoma and anemia as bone marrow stem cell potency.  The most common disease category has been leukemia. The next largest group is inherited diseases. Patients with lymphoma, myelodysplasia and severe aplastic anemia have also been successfully transplanted with cord blood. Cord blood is obtained by syringing out the placenta through the umbilical cord at the time of childbirth, after the cord has been detached from the newborn. Collecting stem cells from umbilical blood and tissue is ethical, pain-free, safe and simple. When they are needed to treat your child later in life, there will be no rejection or incompatibility issues, as the procedure will be using their own cells. In contrast, stem cells from donors do have these potential problems. By consider about cord blood potency, cord blood banks (familial or public were established. In IRAN, four cord blood banks has activity, Shariati BMT center cord blood bank, Royan familial cord blood banks, Royan public cord blood banks and Iranian Blood Transfusion Organ cord blood banks.

    CHS is a rare immunodeficiency syndrome with defects in the functions of cytotoxic cells and neutrophils. Approximately 85% of patients with CHS undergo an AP within the first decade, which is similar to FHLH. Chemotherapy could induce transient remission, but only allogeneic HCT could correct the underlying genetic defect and prevent relapse. We reported a case of CHS diagnosed at 19 months, who had an elder brother who had previously succumbed to the same disease. The little girl presented with severe AP manifestations including recurrent high fever, enlarged superficial lymph nodes, and extraordinary hepatosplenomegaly occupying the whole abdominal and pelvic cavity. Comprehensive therapies including HLH 2004 protocol, supportive care, and antibiotics, especially antituberculous agents, were given to her to induce remission. After remission, the patient received fully HLA-matched UCBT. The transplantation course was uneventful, except for fluctuation of donor chimerism. The patient has been alive for 36 months without infection and neurologic manifestations and is under further follow-up. Our result provides another case that UCBT can be effective for treating patients with CHS and remission before HCT is important for good prognosis. © 2017 John Wiley & Sons A/S.

    Endocannabinoids including anandamide and 2-arachidonoylglycerol are involved in cancer pathophysiology in several ways, including tumor growth and progression, peritumoral inflammation, nausea and cancer pain. Recently we showed that the endocannabinoid profiles are deranged during cancer to an extent that this manifests in alterations of plasma endocannabinoids in cancer patients, which was mimicked by similar changes in rodent models of local and metastatic cancer. The present topical review summarizes the complexity of endocannabinoid signaling in the context of tumor growth and metastasis.

    Vasculogenic mimicry (VM), a microvascular channel made up of nonendothelial cells, has been accepted as a new model of neovascularization in aggressive tumors, owning to the specific capacity of malignant cells to form vessel-like networks which provide sufficient blood supply for tumor growth. Multiple molecular mechanisms, especially vascular endothelial (VE)-cadherin, erythropoietin-producing hepatocellular receptor A2 (EphA2), phosphatidyl inositol 3-kinase (PI3K), matrix metalloproteinases (MMPs), vascular endothelial growth factor receptor (VEGFR1), and hypoxia inducible factor (HIF)-1a, have been reported to participate in VM formation which is associated with tumor migration and invasion. In addition, hypoxia, cancer stem cells (CSCs) and epithelial-mesenehymal transition (EMT) are regarded as significant factors in VM formation and tumor metastasis. Due to the important effects of VM on tumor progression, a review was carried out in the present study, to synthetically analyze the relationship between VM and tumor metastasis.

    Patients with pre-existing cervical spinal canal stenosis (CSCS) may have minimal or no symptoms. However, performing preventive decompression is controversial as the incidence of CSCS leading to severe cord injury is unknown. Hence, this study aims to revisit the threshold for surgery in "silent" CSCS by reviewing the neurologic outcomes of patients with undiagnosed CSCS who sustained a cervical spinal cord injury (CSCI). Two groups of subjects were recruited for analysis. Firstly, patients with trauma-induced CSCI without fracture or dislocation were included. Pre-existing CSCS was diagnosed by MRI measurements. The second group consisted of asymptomatic subjects recruited from the general population who also had MRIs performed. Canal sizes were compared between this control group and the patient group. Within the patient group, neurological assessments and outcomes by Frankel classification were performed in patients treated surgically or conservatively. 32 patients with CSCS were recruited. The mean spinal canal sagittal diameter (disc-level) of all CSCS cases was 5.3 ± 1.4 mm (1.3-8.2). In comparison, the diameter was 10.5 ± 1.7 mm (6.6-14.6) in the 47 asymptomatic individuals recruited from the general population. Decompression was performed in 17 patients and conservative treatment in 15. Mean follow-up was 19.3 ± 17.0 months (6-84). At the final follow-up, 3 patients (9.3%) returned to their pre-injury Frankel grade, whereas 26 patients (83.3%) lost one or more neurological grade. Three patients (9.3%) died. Majority of patients with "silent" CSCS who sustained cervical cord injuries did not return to their pre-injury neurological status. All of these subjects have pre-existing canal stenosis hence the risk of cord injury. Given the poor neurological outcome of CSCS, a lower threshold for surgery could be indicated to avoid these disastrous injuries. However, before making any conclusive recommendation we must first identify the prevalence of

Even if the patient had distant metastasis, total thyroidectomy and radioiodine therapy show good response. Forty seven percent of bone metastases are found in the initial diagnosis, in which vertebral metastases is 29%, pelvic metastases 22%. The metastases to vertebrae often combine spinal cord compression, making it difficult to deliver enough radiation dose to the lesion with radioiodine or external beam irradiation. Brain metastases is found in less than 1% of thyroid cancer, and is also difficult to cure. In Korea Cancer Center Hospital, from 1997 to 2002, we analyzed 437 patients with thyroid cancer who were treated with radioiodine after total thyroidectomy. There were four patients with brain metastases, and 32 patients with vertebral metastases. In four patients with brain metastases, one patient, who also had bone metastases, received high dose radioiodine therapy after total thyroidectomy, and is alive for more than 15 months. Another patients received total thyroidectomy, radioiodine therapy and external irradiation therapy, and survived 22 months. Two patients refused further treatment and died in one month. I-131 uptake in the metastatic lesion in brain is reported to be 17%, and multimodality therapy with surgery, radioiodine therapy, external irradiation and chemotherapy may improve the prognosis. In 32 patients with vertebral metastases, 19 patients (59.4%) showed I-131 uptake after high dose radioiodine therapy, and 5 year survival rate was 65.8%. 13 patients without I-131 uptake after radioiodine therapy had 26.9% of 5 year survival rate. In 11 patients with spinal cord compression, 7 patients received high dose radioiodine therapy and external irradiation after total thyroidectomy and spinal surgery, and six

    MR imaging has significantly improved diagnostic capability of spinal cord injuries. Other available diagnostic modalities such as plain films, myelography, CT, and post-CT myelography have failed to consistently show the secific evidence of spinal cord injuries and their true extent. The authors are presenting our experiences with MR imaging in spinal column injury. They have found MR imaging to be the procedure of choice for prognostic evaluation of spinal cord trauma. They are showing examples of recent and old spinal cord injury such as hematomyelia, myelomalacia, transection, spinal cord edema, and cavitation

  17. Changes in the relative risk and sites of central nervous system metastasis with effective combined chemotherapy and radiation therapy for small cell carcinoma of the lung

    Prolongation of survival of patients with small cell carcinoma of the lung with current effective systemic therapy has been accompanied by a marked increase in the frequency of relapse in the central nervous system (CNS). Prophylactic cranial irradiation (PCI) was shown to reduce the frequency of brain metastasis, but there was no increased short-term survival. Therefore, the necessity for PCI early in the course of treatment has been questioned, especially for patients with extensive disease. From January 1974 through March 1982, 205 patients with small cell carcinoma of the lung were treated at the Medical College of Wisconsin Affiliated Hospitals. None had clinical, radioisotopic, or computed tomographic evidence of brain metastasis. Eighty-two patients received radiotherapy and chemotherapy, but no PCI; 123 patients received combination chemotherapy and radiation therapy with PCI. The cumulative probability of brain metastasis without PCI was 36% at 12 months and 47% at 24 months; the probabilities were 6 and 10%, respectively with PCI. The 24-month probability of brain metastasis in patients with limited disease and no PCI was 45%; for those with extensive disease, it was 47%. No patient presented with extracranial central nervous system (ECNS) metastasis and no one without PCI developed it. Twelve patients who received PCI developed ECNS metastasis; the cumulative probabilities rose to 14% at 12 months and 22% at 24 months. The increased frequency of ECNS involvement has led to a phase I trial of PCI followed by six cycles of combination chemotherapy, without maintenance chemotherapy, followed by irradiation of the chest and spinal cord for patients with complete response

  18. Diagnostic study with CT and MR on the metastasis of malignant brain tumors

    International Nuclear Information System (INIS)

    Miyagami, Mitsusuke; Kasahara, Eishi; Tazoe, Makoto; Tsubokawa, Takashi

    1990-01-01

    Forty cases of malignant brain tumors with metastasis which involved 14 malignant gliomas, 15 medulloblastomas and 11 germ cell tumors were studied on CT and MRI. In malignant glioma, transventricular metastasis was seen most frequently, estimating 8 cases (57%) of 14 malignant gliomas with metastasis and showing ependymal-subependymal enhancement on contrast-enhanced CT (CECT). Most of the medulloblastoma with metastasis demonstrated diffuse subarachnoid seeding in the craniospinal space and on image analysis diffuse sulcal-cisternal enhancement was characterized. Trans-ventricular metastasis in medulloblastoma was less than in malignant glioma showing 3 cases (20%) of 15 medulloblastomas, which in most cases showed a nodular tumor in the ventricular wall by metastasis. There were six patients who, on the first admission, were found to have germ cell tumors of the broad infiltrating type with multiple lesions. The tumor sites of metastasis were different from those with malignant gliomas, being frequently localized in the pineal and/or the suprasellar region, on the ventricular wall and in the basal ganglia. Metastasis to a remote area in germ cell tumors was to spinal cords, to the ventricular wall and basal cistern around the brain stem by CSF dissemination, to the lung by hematogenous metastasis and to the peritoneal wall or organs through V-P shunt tube. T 1 -weighted Gd-DTPA MRI was more useful and sensitive than CECT for diagnosis of the leptomeningeal metastasis, particularly for sulcal-cisternal and spinal metastasis. It will be used more often as the first choice for diagnosis of intrathecal metastasis in the future. (author)

    2015-03-01

    A 2-month-old female infant, born to consanguineous parents, presented with infections in skin and upper respiratory tract. She was notable for delayed umbilical cord detachment, partial albinism, and neurological irritability. Giant granules were present in white blood cells. The intracellular perforin content in CD8 T cells seems to correlate to the immune activation state of the patient with 82% and 8% perforin-containing CD8 T cells at active and nonactive hemophagocytic lymphohistiocytosis (HLH) disease, respectively. HLH was confirmed by hemophagocytosis in bone marrow and absent natural killer cell activity. The patient carried a homozygous G>A mutation in the 3' splice site of intron 24 of the LYST/CHS1 gene, leading to the use of an alternative YAG splice site located in exon 25, introducing a premature STOP codon (L2355fsX2370; NP_000072.2). The early-onset accelerated phase in this severe phenotype of Chediak-Higashi syndrome was probably induced by rotaviral infection. Interestingly, the intracellular perforin content in CD8 T cells seems to correlate to the immune activation state of the patient. Late separation of the umbilical cord in concordance with clinical symptoms should lead to evaluation of a possible neutrophil dysfunction including Chediak-Higashi syndrome before onset of HLH.

    Invasive lobular carcinomas are the second most common type (5% to 15%) of invasive breast carcinomas. The most frequent sites of breast cancer metastasis are the local and distant lymph nodes, brain, lung, liver, and bones; metastasis to the gastrointestinal system, especially to the stomach, is rare. When a mass is detected in an unusual place in a patient with invasive lobular carcinoma, it should be kept in mind that such a mass may be either a second primary carcinoma or the metastasis of an invasive lobular carcinoma. In this report, we present a case of gastric metastasis from triple-negative invasive lobular breast cancer. It is important to make an accurate diagnosis by distinguishing gastric metastasis from breast cancer in order to select the best initial treatment for systemic diseases of breast cancer. Considering our case, healthcare professionals should take into account that cases with invasive lobular breast cancer may experience unusual metastases.

  15. Choroidal melanoma of left eye with very early liver metastasis.

    2015-01-01

    Uveal melanoma is a cancer (melanoma) of the eye involving the iris, ciliary body, or choroid (collectively referred to as the uvea). The liver is a frequent site for metastasis in patients with uveal melanoma. The interval between the diagnosis of the uveal melanoma and the diagnosis of the metastatic lesion can vary. Despite therapy, the median survival of those with liver metastasis is 5-7 months. We report here a rare case of choroidal melanoma in a 45-year-old male smoker presented with liver metastasis within just 8 months after completion of initial treatments consists of enucleation of eye and 3 Dimensional conformal radiation therapy (3D-CRT). The metastasis is an incidental finding on imaging after having some vague symptoms. This type of very early metastasis after completing initial treatment is very rare and proves the aggressiveness of the disease.

    2016-01-01

    Full Text Available Skeletal muscle metastasis of nonsmall cell lung carcinoma (NSCLC is a rare occurrence, and the most effective treatment modality is currently unknown. In this case presentation, we report a patient with NSCLC who underwent palliative radiotherapy for biceps muscle metastasis of NSLCS. Our case was a 49-year-old woman who had lung adenocarcinoma with biceps muscle metastasis. She had been followed up for 2 years due to Stage IV lung adenocarcinoma from whom a biopsy was taken from a painful mass in right arm that was found to be compatible with metastasis of lung adenocarcinoma. She had palliative radiotherapy for her painful mass and systemic chemotherapy was planned. After palliative radiotherapy, the pain originating from the metastatic mass in right biceps muscle alleviated. Palliative radiotherapy can be a valuable treatment option for cases with skeletal muscle metastasis.

  18. Lung Adenocarcinoma Presenting as Worsening of Chronic Neck Pain—A Cautionary Tale

    Directory of Open Access Journals (Sweden)

    Neeka N Akhavan

    2017-02-01

    Full Text Available Introduction: Neck pain is a common musculoskeletal problem that up to 70% of the world population will experience at some point in their lives. Intramedullary spinal cord metastasis is an exceedingly rare complication of malignancy that affects less than 1% of all patients with cancer. Case report: We report a case of a 61-year-old man who presented to primary care clinic with 1-month history of worsening neck pain with associated neurologic deficits. Despite initial conservative management, the patient continued to have progressive worsening of sensory and motor deficits. Magnetic resonance imaging of the cervical spine showed vasogenic edema of the brain and spinal cord and nodularity at the C4-C5 level. A computed tomography of the chest showed a dense lesion in the left lower lobe of the lung; histopathology of the biopsied specimen was consistent with moderately differentiated lung adenocarcinoma. Conclusions: A high index of suspicion is necessary when chronic neck pain acutely worsens, changes in character, or is accompanied by neurologic deficits. These clinical signs warrant further investigation into a secondary cause of neck pain. Intramedullary spinal cord metastases are rare complications of systemic cancer that commonly present with neck pain and upper extremity paraesthesias; early diagnosis and management are necessary to prevent complications such as spinal cord hemisection syndrome or spinal cord transection.

    Contrast enhanced CT on 6 patients with spinal cord angioma showed enhancement in 2 of them. The conditions to produce contrast enhancement were the window width of 100 - 200, and the window level of 0 - 50. In spinal cord angioma, contrast enhanced CT is presently only an adjunct to angiography and myelography. Nevertheless, contrast enhanced CT is useful in the screening test for spinal cord angioma, in the patients who are nonindicated to angiography, and in the postoperative follow-up. (Ueda, J.)

    2009-09-01

    International private umbilical cord blood banking has expanded rapidly in recent years since the first cord blood transplant which was 20 years ago. Private companies offer parents the opportunity to store umbilical cord blood for the possible future use by their child or other family members. The private cord blood industry has been criticised by a number of professional bodies including the EU Ethics Committee, the Royal College of Obstetrics and Gynaecology, the Royal College of Midwives and the US College of Paediatrics. This review presents the arguments from the opponents of private cord blood banking, and then makes the case for private cord banking based on the latest scientific and clinical evidence.

    2015-03-01

    Tumors of the clivus and metastases to the clivus are very rare. Metastasis involving the clivus has previously been described in only two case reports. In skull metastasis, the breast and prostate are the most common primary foci, while metastasis from gastric carcinoma is extremely rare. A review of the English literature revealed only one published case of clivus metastases from gastric adenocarcinoma. There is no literature thoroughly explaining the differential diagnosis between chordoma and metastasis. Here we report a rare case of metastasis to the clivus from a gastric adenocarcinoma in a 42-year-old female patient with sudden blurry vision, presenting as bilateral cranial nerve VI palsy.

    2014-01-01

    Full Text Available Ectopic breast tissue has the ability to undergo all the pathological changes of the normal breast, including breast cancer. Gastrointestinal metastasis of breast cancer is rarely observed and it is very difficult to differentiate gastric metastases from primary gastric cancer. We present a case of 52-year-old female, who suffered from abdominal pain. Physical examination showed a palpable mass in the left anterior axilla and computerized tomography revealed gastric wall thickening with linitis plastica. When gastroscopic biopsy showed no signs of malignancy, excisional biopsy was performed in the left axilla. Histological examination revealed invasive lobular carcinoma of the breast, consistent with ectopic breast cancer. Further gastroscopic submucosal biopsies and immunohistochemical studies revealed gastric metastases of invasive lobular carcinoma. Axillary ectopic breast tissue carcinomas can mimic axillary lymphadenopathies. Additionally, gastric metastasis of breast cancer is an uncommon but possible condition. To the best of our knowledge, this is the first report of ectopic breast cancer with gastric metastasis.

    Full Text Available Renal medullary carcinoma (RMC is a rare, aggressive primary renal malignancy that classically occurs in adolescent males with sickle cell trait and universally presents with metastatic disease at presentation. We report a case of medullary carcinoma in a young man with likely ophthalmic metastasis. We also review relevant literature available to date. The patient is a 20-year-old African-American male with a past medical history significant to for sickle cell trait who presented to the University Medical Center with cough and the right eye pain for 1 month as well as painless gross hematuria for 1 week. A chest and abdominal computed tomography showed a 7 cm hypodense right renal mass with bilateral hilar adenopathy, and multiple bilateral pulmonary nodules. A renal biopsy was performed and showed RMC. Ophthalmic exam revealed the right retinal hemorrhage concerning for a metastatic lesion. Palliative chemotherapy was offered to the patient, however, he and his family chose to enroll in hospice care considering his poor prognosis. He subsequently passed away 33 days after presentation. To our knowledge, there is only one other case of ophthalmic metastasis in a patient with metastatic RMC. Thus, we present this case to contribute to current literature regarding orbital metastasis in this largely fatal disease.

  14. Twiddler's syndrome in spinal cord stimulation.

    Science.gov (United States)

    Al-Mahfoudh, Rafid; Chan, Yuen; Chong, Hsu Pheen; Farah, Jibril Osman

    2016-01-01

    The aims are to present a case series of Twiddler's syndrome in spinal cord stimulators with analysis of the possible mechanism of this syndrome and discuss how this phenomenon can be prevented. Data were collected retrospectively between 2007 and 2013 for all patients presenting with failure of spinal cord stimulators. The diagnostic criterion for Twiddler's syndrome is radiological evidence of twisting of wires in the presence of failure of spinal cord stimulation. Our unit implants on average 110 spinal cord stimulators a year. Over the 5-year study period, all consecutive cases of spinal cord stimulation failure were studied. Three patients with Twiddler's syndrome were identified. Presentation ranged from 4 to 228 weeks after implantation. Imaging revealed repeated rotations and twisting of the wires of the spinal cord stimulators leading to hardware failure. To the best of our knowledge this is the first reported series of Twiddler's syndrome with implantable pulse generators (IPGs) for spinal cord stimulation. Hardware failure is not uncommon in spinal cord stimulation. Awareness and identification of Twiddler's syndrome may help prevent its occurrence and further revisions. This may be achieved by implanting the IPG in the lumbar region subcutaneously above the belt line. Psychological intervention may have a preventative role for those who are deemed at high risk of Twiddler's syndrome from initial psychological screening.

  9. The recurrent true umbilical cord knots: a case report

    Directory of Open Access Journals (Sweden)

    I Naghi

    2012-11-01

    Full Text Available Background: True umbilical cord knot is one of the abnormalities of the umbilical cord. Active fetal movements create cord knotting. True umbilical cord knots are rare but may be associated with fetal distress and stillbirth. True umbilical cord knots are capable of impeding blood flow to the fetus.Case presentation: A 26-year old primigravid woman was first treated for genital herpes simplex virus (HSV type 2 at 36 weeks of gestational age. She received oral acyclovir (400 mg three times daily for 10 days. At the gestational age of 38 weeks and 5 days, fetal activity decreased and NST was nonreactive. She was delivered by cesarean section and a true umbilical cord knot was found. Four years later, in her second pregnancy, another true knot was seen.Conclusion: Excessively long umbilical cords are more likely to be associated with true knots. Genetics has an important role in determining cord length and occurrence of true knots.

  10. Experience of treating late cerebral lungcancer metastasis using photodynamic therapy

    Directory of Open Access Journals (Sweden)

    A. I. Ryabova

    2013-01-01

    Full Text Available Treatment outcomes for a patient with solitary brain metastasis after long-term relapse-free follow-up of invasive lung carcinoma were presented. Brain metastasis without other signs of disease progression was diagnosed 10 years after combined modality treatment for stage II lung cancer. Removal of intracerebral metastasis with intraoperative photodynamic therapy was performed. Histology microspecimens of the primary tumor and metastasis were similar. No signs of disease progression in the brain 9 months after surgery were found. This case demonstrates that it is important to increase cancer suspicion for patients with long-term relapse-free follow-up. The use of intraoperative photodynamic therapy with photoditazine as a sensitizer in the treatment of cerebral metastases results in a favorable anti-tumor effect, thus improving life quality of patients

  11. Cervical Cord-Canal Mismatch: A New Method for Identifying Predisposition to Spinal Cord Injury.

    Science.gov (United States)

    Nouri, Aria; Montejo, Julio; Sun, Xin; Virojanapa, Justin; Kolb, Luis E; Abbed, Khalid M; Cheng, Joseph S

    2017-12-01

    The risk for spinal cord injuries (SCIs) ranging from devastating traumatic injuries, compression because of degenerative pathology, and neurapraxia is increased in patients with congenital spinal stenosis. Classical diagnostic criteria include an absolute anteroposterior diameter of spinal cord, which varies across patients, independent of canal size. Recent large magnetic resonance imaging studies of population cohorts have allowed newer methods to emerge that account for both cord and canal size by measuring a spinal cord occupation ratio (SCOR). A SCOR defined as ≥70% on midsagittal imaging or ≥80% on axial imaging appears to be an effective method of identifying cord-canal mismatch, but requires further validation. Cord-canal size mismatch predisposes patients to SCI because of 1) less space within the canal lowering the amount of degenerative changes needed for cord compression, and 2) less cerebrospinal fluid surrounding the spinal cord decreasing the ability to absorb kinetic forces directed at the spine. Patients with cord-canal mismatch have been reported to be at a substantially higher risk of traumatic SCI, and present with degenerative cervical myelopathy at a younger age than patients without cord-canal mismatch. However, neurologic outcome after SCI has occurred does not appear to be different in patients with or without a cord-canal mismatch. Recognition that canal and cord size are both factors which predispose to SCI supports that cord-canal size mismatch rather than a narrow cervical canal in isolation should be viewed as the underlying mechanism predisposing to SCI.

    2012-01-01

    To report pain relief effect in patients with spinal metastases treated with Cyberknife® and to analyze the factors associated with pain relapse after initial pain relief. We retrospectively analyzed patients with spinal metastasis treated with stereotactic body radiosurgery between April 2007 and June 2009. A total of 57 patients with 73 lesions were available for analysis with a median follow-up of 6.8 months (range, 1-30). Pain was assessed by a verbal/visual analogue scale at each visit: from 0 to 10. Pain relief was defined as a decrease of at least three levels of the pain score without an increase in analgesic use. Complete relief was defined as no analgesics or a score 0 or 1. Pain relief was achieved in 88% of the lesions, with complete relief in 51% within 7 days from the start of radiosurgery. The median duration of pain relief was 3.2 months (range, 1-30). Pain reappeared in 16 patients (27%). Spinal cord compression (P = 0.001) and performance status (P = 0.01) were predictive of pain relapse by multivariate Cox analysis. All 6 patients treated with solitary spinal metastasis experienced pain relief; 5 of them were alive without evidence of disease at a median of 16 months (range, 7-30). As previous studies have shown, our study confirms that pain relief with spinal radiosurgery is around 90%. In particular, long-term pain relief and disease control was observed in patients with solitary spinal metastasis.

  19. Presentation of an umbilical cord cyst with a surprising jet: a case report of a patent urachus [v1; ref status: indexed, http://f1000r.es/xx

    Directory of Open Access Journals (Sweden)

    John Svigos

    2013-02-01

    Full Text Available We report a baby with an unusual true umbilical cord cyst detected at 12 weeks gestation which as the pregnancy progressed became increasingly difficult to distinguish from a pseudocyst of the umbilical cord. Concern of the possibility of cord compression/cord accident led to an elective caesarean section being performed at 35+ week’s gestation with delivery of a healthy female infant weighing 2170g. At birth the cyst ruptured and the resultant thickened elongated cord was clamped accordingly. After the cord clamp fell off at 5 days post delivery an elongated umbilical stump was left behind from which a stream of urine surprisingly jetted out from the umbilicus each time the baby cried. A patent urachus was confirmed on ultrasound and the umbilical jet of urine resolved at 4 weeks post delivery after treatment of an Escherichia coli urinary tract infection. At 11 weeks post delivery a laparoscopic excision of the urachus was successfully performed. The baby, now 18 months of age, continues to thrive without incident.

  20. Prenatal diagnosis of placenta and umbilical cord pathologies by three-dimensional ultrasound: pictorial essay.

    de Castro Rezende, Guilherme; Araujo Júnior, Edward

    2015-12-01

    The authors present their experience in prenatal diagnosis of placental and umbilical cord pathologies, using three-dimensional ultrasound (3DUS) in the rendering and tomography ultrasound imaging (TUI) modes, associated with color Doppler in some cases. Cases of placenta accreta/placenta previa, circumvallate placenta, succenturiate lobe, true knot of the umbilical cord, nuchal cord, and marginal/velamentous umbilical cord insertion are presented. 3DUS can contribute to improve the accuracy of prenatal diagnosis of placenta and umbilical cord pathologies.

  1. Cervical spinal cord injury in abused children.

    Feldman, Kenneth W; Avellino, Anthony M; Sugar, Naomi F; Ellenbogen, Richard G

    2008-04-01

    Five infants and toddlers who sustained cervical spinal cord injury as the result of child abuse are described. Three cases are previously unreported. Diagnosis was complicated by coexistent brain injuries and their treatments, subtle and/or evolving paralysis, and central cord syndrome, in which arm function is diminished but leg function is preserved. Definitive spinal imaging by magnetic resonance imaging (MRI), computed tomography, and plain radiographs was delayed because of life support efforts. When completed, the MRI was most sensitive to cord injury. Evidence of associated bony spinal injury was often absent or unapparent until healing occurred; 4 children had spinal cord injury without (or with minimal) radiological abnormality. The 3 children presenting to our hospital with cord injury represent 1% of the estimated cases of inflicted head injury seen during a 23-year period.

  2. Remodeling of the methylation landscape in breast cancer metastasis.

    Directory of Open Access Journals (Sweden)

    Marsha Reyngold

    Full Text Available The development of breast cancer metastasis is accompanied by dynamic transcriptome changes and dramatic alterations in nuclear and chromatin structure. The basis of these changes is incompletely understood. The DNA methylome of primary breast cancers contribute to transcriptomic heterogeneity and different metastatic behavior. Therefore we sought to characterize methylome remodeling during regional metastasis. We profiled the DNA methylome and transcriptome of 44 matched primary breast tumors and regional metastases. Striking subtype-specific patterns of metastasis-associated methylome remodeling were observed, which reflected the molecular heterogeneity of breast cancers. These divergent changes occurred primarily in CpG island (CGI-poor areas. Regions of methylome reorganization shared by the subtypes were also observed, and we were able to identify a metastasis-specific methylation signature that was present across the breast cancer subclasses. These alterations also occurred outside of CGIs and promoters, including sequences flanking CGIs and intergenic sequences. Integrated analysis of methylation and gene expression identified genes whose expression correlated with metastasis-specific methylation. Together, these findings significantly enhance our understanding of the epigenetic reorganization that occurs during regional breast cancer metastasis across the major breast cancer subtypes and reveal the nature of methylome remodeling during this process.

    2017-09-01

    Spinal cord perimedullary arteriovenous fistulas (PMAVFs) are rare and belong to type IV spinal cord arteriovenous malformations (AVMs). Little is known regarding the treatment and prognosis of spinal cord PMAVFs. In the present study the relevant literature from PubMed was reviewed, and it was found that these fistulas can occur at all ages but are more common in children. In children, most spinal cord PMAVFs are large and with high flow, begin with bleeding and are frequently associated with hereditary hemorrhagic telangiectasia. However, in adults, most spinal cord PMAVFs are small and with low flow and begin with progressive spinal cord dysfunction. The early diagnosis of spinal cord PMAVFs is generally difficult, and symptoms can be very severe at the time of diagnosis. Digital subtraction angiography remains the gold standard; however, computed tomography angiography and magnetic resonance angiography are also promising. Spinal cord PMAVFs can be treated by endovascular embolization, surgical removal or a combination of the two methods. Most spinal cord PMAVFs show good outcomes after the appropriate treatment, and the prognosis is primarily associated with the blood flow of the PMAVF. For high-flow spinal cord PMAVFs, endovascular embolization is more effective and can lead to a good outcome; however, for low-flow spinal cord PMAVFs, surgical removal or the combination with endovascular embolization is the optimal choice. The prognosis for low-flow types is slightly worse than for high-flow spinal cord PMAVFs in children, but the outcome is acceptable.

  4. Reactive Astrocytes in Brain Metastasis

    Directory of Open Access Journals (Sweden)

    David Wasilewski

    2017-12-01

    Full Text Available Brain metastasis, the secondary growth of malignant cells within the central nervous system (CNS, exceeds the incidence of primary brain tumors (i.e., gliomas by tenfold and are seemingly on the rise owing to the emergence of novel targeted therapies that are more effective in controlling extracranial disease relatively to intracranial lesions. Despite the fact that metastasis to the brain poses a unmet clinical problem, with afflicted patients carrying significant morbidity and a fatal prognosis, our knowledge as to how metastatic cells manage to adapt to the tissue environment of the CNS remains limited. Answering this question could pave the way for novel and more specific therapeutic modalities in brain metastasis by targeting the specific makeup of the brain metastatic niche. In regard to this, astrocytes have emerged as the major host cell type that cancer cells encounter and interact with during brain metastasis formation. Similarly to other CNS disorders, astrocytes become reactive and respond to the presence of cancer cells by changing their phenotype and significantly influencing the outcome of disseminated cancer cells within the CNS. Here, we summarize the current knowledge on the contribution of reactive astrocytes in brain metastasis by focusing on the signaling pathways and types of interactions that play a crucial part in the communication with cancer cells and how these could be translated into innovative therapies.

  5. Frequency of brain metastasis in adenocarcinoma and large cell carcinoma of the lung: correlation with survival

    International Nuclear Information System (INIS)

    Komaki, R.; Cox, J.D.; Stark, R.

    1983-01-01

    From January 1970 through December 1981, 469 patients with histologically or cytologically proven adenocarcinoma (AC) (349) and large cell carcinoma (LC) (120) of the lung were seen at the Department of Radiation Oncology, Medical College of Wisconsin Affiliated Hospitals. One quarter (126/469) of these patients had brain metastasis: 48 patients presented with brain metastasis and 78 patients subsequently developed brain metastasis. Brain was the dominant site of metastasis in 82 patients who received only cranial + thoracic irradiation; 37 patients (17 simultaneous, 20 metachronous) also required irradiation of other sites of metastasis. All 17 patients with LC, and 47/61 (77%) with AC who developed metachronous brain metastasis did so within one year. The cumulative probability of brain metastasis increased with survival to the levels predicted by autopsy studies. Therapeutic brain irradiation may result in long-term survival in patients with single organ brain metastasis. Since patients with AC and LC so frequently develop brain metastasis and the brain may be the only site of metastasis, prophylactic cranial irradiation may significantly reduce morbidity and mortality from these diseases

  6. Paradoxical vocal cord dysfunction: when a wheeze is not asthma.

    2008-04-01

    Vocal cord dysfunction (VCD) is an uncommon condition which often mimics asthma in presentation and severity. We present nine- and 11-year-old female siblings with vocal cord dysfunction, which is a dysfunction of the larynx involving unintentional paradoxical adduction of the vocal cords during inspiration. We evaluated the use of exercise testing in conjunction with pulmonary function testing in suspected vocal cord dysfunction. Although normal pulmonology function tests were elicited with the patient at rest, exercise testing revealed blunting of the expiratory loop with attenuation of the inspiratory loop unique to VCD. The child underwent video laryngoscopy in the specialised voice clinic, which confirmed vocal cord dysfunction. Exercise testing is a rapid and noninvasive means of diagnosing vocal cord dysfunction in a small subset of patients, but video laryngoscopy, with training manoeuvres to elicit paradoxical vocal cord movements in VCD, remains the gold standard of diagnosis of VCD.

  7. Nodal metastasis in thyroid cancer

    International Nuclear Information System (INIS)

    Samuel, A.M.

    1999-01-01

    The biological behavior and hence the prognosis of thyroid cancer (TC) depends among other factors on the extent of spread of the disease outside the thyroid bed. This effect is controversial, especially for nodal metastasis of well differentiated thyroid carcinoma (WDC). Nodal metastasis at the time of initial diagnosis behaves differently depending on the histology, age of the patient, presence of extrathyroidal extension, and the sex of the individual. The type of the surgery, administration of 131 I and thyroxin suppression also to some extent influence the rate of recurrence and mortality. Experience has shown that it is not as innocuous as a small intrathyroidal tumor without any invasion outside the thyroid bed and due consideration should be accorded to the management strategies for handling patients with nodal metastasis

  8. Topologically preserving straightening of spinal cord MRI.

    2017-10-01

    To propose a robust and accurate method for straightening magnetic resonance (MR) images of the spinal cord, based on spinal cord segmentation, that preserves spinal cord topology and that works for any MRI contrast, in a context of spinal cord template-based analysis. The spinal cord curvature was computed using an iterative Non-Uniform Rational B-Spline (NURBS) approximation. Forward and inverse deformation fields for straightening were computed by solving analytically the straightening equations for each image voxel. Computational speed-up was accomplished by solving all voxel equation systems as one single system. Straightening accuracy (mean and maximum distance from straight line), computational time, and robustness to spinal cord length was evaluated using the proposed and the standard straightening method (label-based spline deformation) on 3T T 2 - and T 1 -weighted images from 57 healthy subjects and 33 patients with spinal cord compression due to degenerative cervical myelopathy (DCM). The proposed algorithm was more accurate, more robust, and faster than the standard method (mean distance = 0.80 vs. 0.83 mm, maximum distance = 1.49 vs. 1.78 mm, time = 71 vs. 174 sec for the healthy population and mean distance = 0.65 vs. 0.68 mm, maximum distance = 1.28 vs. 1.55 mm, time = 32 vs. 60 sec for the DCM population). A novel image straightening method that enables template-based analysis of quantitative spinal cord MRI data is introduced. This algorithm works for any MRI contrast and was validated on healthy and patient populations. The presented method is implemented in the Spinal Cord Toolbox, an open-source software for processing spinal cord MRI data. 1 Technical Efficacy: Stage 1 J. Magn. Reson.

    The aim of this study is to identify and describe the computed tomography and scintigraphic imaging patterns of osseous metastasis from invasive lobular breast cancer (ILC). CT and skeletal scintigraphy (SS) studies of 23 patients with diagnosis of ILC and osseous metastasis on their initial presentation were reviewed. Osseous metastases in 14 patients (60.8%) appear as uniform small sclerotic lesions (USSL) on CT scan. The SS in these patients were interpreted as negative for metastasis (either normal or with some equivocal findings not typical for metastasis). Osseous metastasis from ILC can have a characteristic imaging pattern on CT and SS. The pattern of USSL on CT scan with negative SS is highly suggestive of osseous metastasis from ILC. © 2015 The Royal Australian and New Zealand College of Radiologists.

  11. Spinal cord injury reveals multilineage differentiation of ependymal cells.

    Directory of Open Access Journals (Sweden)

    Konstantinos Meletis

    2008-07-01

    Full Text Available Spinal cord injury often results in permanent functional impairment. Neural stem cells present in the adult spinal cord can be expanded in vitro and improve recovery when transplanted to the injured spinal cord, demonstrating the presence of cells that can promote regeneration but that normally fail to do so efficiently. Using genetic fate mapping, we show that close to all in vitro neural stem cell potential in the adult spinal cord resides within the population of ependymal cells lining the central canal. These cells are recruited by spinal cord injury and produce not only scar-forming glial cells, but also, to a lesser degree, oligodendrocytes. Modulating the fate of ependymal progeny after spinal cord injury may offer an alternative to cell transplantation for cell replacement therapies in spinal cord injury.

    2016-01-01

    Preeclampsia is associated with abnormalities in the umbilical cord in several ways: morphological, biochemical and functional. Alteration in blood vessels of the placenta, decidua and circulatory system of the fetus might be related to factors that cause preeclampsia and may be associated with alterations of the umbilical cord. This study aimed to analyze the relationship between each type of umbilical cord abnormality and the different subtypes of hypertensive gestational disorders. We conducted a prospective study on consecutive autopsies and its placentas, looking for abnormalities in the umbilical cord's features and their clinical associations. Umbilical cord abnormalities including length, diameter, insertion, entanglements, knots and coils were associated with maternal gestational hypertension. In women with gestational hypertension, umbilical cord abnormalities are associated with fetal and neonatal consequences.

    Cancer metastasis is the spread and growth of tumor cells from the original neoplasm to further organs. This review analyzes the role of nitric oxide (NO), a signaling molecule, in the regulation of cancer formation, progression, and metastasis. The action of NO on cancer relies on multiple factors including cell type, metastasis stage, and organs involved. Various chemotherapy drugs cause cells to release NO, which in turn induces cytotoxic death of breast, liver, and skin tumors. However, NO has also been clinically connected to a poor cancer prognosis because of its role in angiogenesis and intravasation. This supports the claim that NO can be characterized as both pro-metastatic and anti-metastatic, depending on specific factors. The inhibition of cell proliferation and anti-apoptosis pathways by NO donors has been proposed as a novel therapy to various cancers. Studies suggest that NO-releasing non-steroidal anti-inflammatory drugs act on cancer cells in several ways that may make them ideal for cancer therapy. This review summarizes the biological significance of NO in each step of cancer metastasis, its controversial effects for cancer progression, and its therapeutic potential.

  14. Pulmonary Metastasis from Pseudomyxoma Peritonei

    Directory of Open Access Journals (Sweden)

    Toshiyuki Kitai

    2012-01-01

    Full Text Available Pseudomyxoma peritonei (PMP is a rare clinical condition, where copious mucinous ascites accumulate in the peritoneal cavity due to dissemination of mucin-producing tumor. Because of this disseminating, yet nonmetastasizing, behavior, PMP attracts much interest from surgical oncologists in that aggressive locoregional therapy can give the opportunity of long survival and even cure. Although extra-abdominal metastasis is exceptionally rare, the lung is the most likely site in such a case. In this paper, the clinical findings and treatment of eleven cases with pulmonary metastasis from PMP were reviewed, including ten cases in the literature and one case which we experienced. The clinical features of PMP cases with pulmonary metastasis were similar to cases without pulmonary metastasis. The histological type was low-grade mucinous neoplasm in most cases. Pulmonary lesions were resected in seven cases in which abdominal lesions were controlled by cytoreductive surgery and hyperthermic intraperitoneal chemotherapy or another therapeutic modality. Disease-free state was maintained in five cases at the end of the follow-up period. However, it should be noted that rapid progression after resection was seen in two cases, suggesting that biological features may have changed by surgical intervention.

    2014-01-01

    Full Text Available A woman in her mid-60s presented with a bulky mass on the anterior abdominal wall. She had a previous incidental diagnosis of endometrial adenocarcinoma FIGO stage IB following a vaginal hysterectomy. Physical exam and imaging revealed a well circumscribed bulging tumour at the umbilical region, measuring 10 × 9 × 9 cm, with overlying intact skin and subcutaneous tissue. Surgical resection was undertaken, and histological examination showed features of endometrial carcinoma. She began chemotherapy and is alive with no signs of recurrent disease one year after surgery. This case brings up to light an atypical location of a solitary metastasis of endometrial carcinoma.

    Retrospective analysis of the influence of clinical and technical factors on local control and survival after radiosurgery for brain metastasis. From january 1994 to December 1996, 42 patients presenting with 71 metastases underwent radiosurgery for brain metastasis. The median age was 56 years and the median Karnofsky index 80. Primary sites included: lung (20 patients), kidney (seven), breast (five), colon (two), melanoma (three), osteosarcoma (one) and it was unknown for three patients. Seventeen patients had extracranial metastasis. Twenty-four patients were treated at recurrence which occurred after whole brain irradiation (12 patients), surgical excision (four) or after both treatments (eight). Thirty-six sessions of radiosurgery have been realized for one metastasis and 13 for two, three or four lesions. The median metastasis diameter was 21 mm and the median volume 1.7 cm 3 . The median peripheral dose to the lesion was 14 Gy, and the median dose at the isocenter 20 Gy. Sixty-five metastasis were evaluable for response analysis. The overall local control rate was 82% and the 1-year actuarial rate was 72%. In univariate analysis, theoretical radioresistance (P = 0.001), diameter less than 3 cm (P = 0.039) and initial treatment with radiosurgery (P 0.041) were significantly associated with increased local control. Only the first two factors remained significant in multivariate analysis. No prognostic factor of overall survival was identified. The median survival was 12 months. Six patients had a symptomatic oedema (RTOG grade 2), only one of which requiring a surgical excision. In conclusion, 14 Gy delivered at the periphery of metastasis seems to be a sufficient dose to control most brain metastases, with a minimal toxicity. Better results were obtained for lesions initially treated with radiosurgery, theoretically radioresistant and with a diameter less than 3 cm. (authors)

    Previously, we showed that human umbilical cord blood (UCB) regulatory T cells (Tregs) could be expanded approximately 100-fold using anti-CD3/28 monoclonal antibody (mAb)–coated beads to provide T-cell receptor and costimulatory signals. Because Treg numbers from a single UCB unit are limited, we explored the use of cell-based artificial antigen-presenting cells (aAPCs) preloaded with anti-CD3/28 mAbs to achieve higher levels of Treg expansion. Compared with beads, aAPCs had similar expansion properties while significantly increasing transforming growth factor β (TGF-β) secretion and the potency of Treg suppressor function. aAPCs modified to coexpress OX40L or 4-1BBL expanded UCB Tregs to a significantly greater extent than bead- or nonmodified aAPC cultures, reaching mean expansion levels exceeding 1250-fold. Despite the high expansion and in contrast to studies using other Treg sources, neither OX40 nor 4-1BB signaling of UCB Tregs reduced in vitro suppression. UCB Tregs expanded with 4-1BBL expressing aAPCs had decreased levels of proapoptotic bim. UCB Tregs expanded with nonmodified or modified aAPCs versus beads resulted in higher survival associated with increased Treg persistence in a xeno-geneic graft-versus-host disease lethality model. These data offer a novel approach for UCB Treg expansion using aAPCs, including those coexpressing OX40L or 4-1BBL. PMID:18645038

    Secondary localization to vagina had a severe prognosis, suggesting a disseminated metatastic disease. We report the case of prevalent vaginal metastasis of adenocarcinoma of the transverse colon. A 65 years old patient has consulted for vaginal mass. After delayed diagnosis, she presented with disseminated metastatic disease with peritoneal carcinomatosis. After neoadjuvant chemotherapy, the following treatment consisted of complete cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy and vaginal adjuvant radiotherapy. No recurrence occurred after one year. Vaginal metastasis of colon cancer are rare. The dark prognosis might justify a systematic gynecological examination of women presenting colorectal neoplasy.

    2009-01-01

    We report a case of isolated gastrointestinal metastasis from breast lobular carcinoma, which mimicked primary anal cancer. In July 2000, an 88-year-old woman presented with infiltrating lobular cancer (pT1/G2/N2). The patient received postoperative radiotherapy and hormonal therapy. Four years later, she presented with an anal polypoid lesion. The mass was removed for biopsy. Immunohistochemical staining suggested a breast origin. Radiotherapy was chosen for this patient, which resulted in complete regression of the lesion. The patient died 3 years after the first manifestation of gastrointestinal metastasis. According to the current literature, we consider the immunohistochemistry features that are essential to support the suspicion of gastrointestinal breast metastasis, and since we consider the gastrointestinal involvement as a sign of systemic disease, the therapy should be less aggressive and systemic.

    Full Text Available Metastatic spermatic cord (SC tumor is extremely rare. Recently, we experienced a case of late-onset metastatic SC tumor from cecal cancer. This case is a 68-year-old man presenting with a painless right SC mass. He had undergone a right hemicolectomy for cecal cancer 6 years ago. Radical orchiectomy and adjuvant chemotherapy with S-1 were performed. No recurrence was found after one year of follow-up. We identified a total of 25 cases, including our case, on a literature search via PubMed from January 2000 to April 2015. The most frequent primary sites of the tumors metastasizing to the SC were the stomach (8 cases, 32% and the colon (8 cases, 32%, next the liver (2 cases, 8%, and kidney (2 cases, 8%. The majority of the cases underwent radical orchiectomy for the metastatic tumors of the SC. Over half of the cases received adjuvant interventions based on the regimens for the primary tumors. Prognosis in the patients with metastatic tumor of the SC was unfavorable except for late-onset metastasis. In patients with a mass in the SC and a history of neoplasm, especially in gastrointestinal tract, the possibility of metastasis from the primary cancer should be considered.

    1986-01-01

    We reported seven cases of acute cervical cord injuries who were examined by CT-Myelography (CTM) within 7 days after trauma. The presence or absence of spinal cord enlargement, the initial neurological status and the neurological prognosis of these patients were studied. The neurological status of each patient was graded by the method of Frankel who defined five grades from A to E according to the severity of neurological deficits. Seven patients were all males. The youngest was 18 and the oldest was 73 years old, with a mean age of 40.7 years. Follows up periods ranged from 7 to 23 months. Result: CTM revealed the enlargement of spinal cord in two cases, who had severe neurological deficits and were graded to A. No neurological improvements were obtained in these cases. Five cases without cord enlargement were graded to A in one patient, B in one patient and C in three patients. Four of these five patients improved neurologically. One grade C patient remained grade C. Complete block of subarachnoid space was observed in two out of seven cases. Cord enlargement was present in one of them. Another case of complete block improved from C to D. Conclusion: We consider the presence of cord enlargement which can be demonstrated by CTM well correlates the severity of the cord damage and presume poor neurological prognosis. Internal decompression, such as posterior longitudinal myelotomy may be recommended to the case of cord enlargement. When the cord enlargement is absent, improvement of neurological grade is expected although the initial neurological status shows severe deficits. (author)

    Although recent technical advancements are directed toward developing novel assays and methods for detection of micro and macro metastasis, there are still no reports of reliable, simple to use imaging software that could be used for the detection and quantification of metastasis in tissue sections. We herein report a new semiquantitative method for evaluation of metastasis progression in a well established 4T1 orthotopic mouse model of breast cancer metastasis. The new semiquantitative method presented here was implemented by using the Autodesk AutoCAD 2012 program, a computer-aided design program used primarily for preparing technical drawings in 2 dimensions. By using the Autodesk AutoCAD 2012 software- aided graphical evaluation we managed to detect each metastatic lesion and we precisely calculated the average percentage of lung and liver tissue parenchyma with metastasis in 4T1 tumor-bearing mice. The data were highly specific and relevant to descriptive histological analysis, confirming reliability and accuracy of the AutoCAD 2012 software as new method for quantification of metastatic lesions. The new semiquantitative method using AutoCAD 2012 software provides a novel approach for the estimation of metastatic progression in histological tissue sections.

  13. Split Cord Malformations

    Directory of Open Access Journals (Sweden)

    Yurdal Gezercan

    2015-06-01

    Full Text Available Split cord malformations are rare form of occult spinal dysraphism in children. Split cord malformations are characterized by septum that cleaves the spinal canal in sagittal plane within the single or duplicated thecal sac. Although their precise incidence is unknown, split cord malformations are exceedingly rare and represent %3.8-5 of all congenital spinal anomalies. Characteristic neurological, urological, orthopedic clinical manifestations are variable and asymptomatic course is possible. Earlier diagnosis and surgical intervention for split cord malformations is associated with better long-term fuctional outcome. For this reason, diagnostic imaging is indicated for children with associated cutaneous and orthopedic signs. Additional congenital anomalies usually to accompany the split cord malformations. Earlier diagnosis, meticuolus surgical therapy and interdisciplinary careful evaluation and follow-up should be made for good prognosis. [Cukurova Med J 2015; 40(2.000: 199-207

  14. Pericytes limit tumor cell metastasis

    DEFF Research Database (Denmark)

    Xian, Xiaojie; Håkansson, Joakim; Ståhlberg, Anders

    2006-01-01

    Previously we observed that neural cell adhesion molecule (NCAM) deficiency in beta tumor cells facilitates metastasis into distant organs and local lymph nodes. Here, we show that NCAM-deficient beta cell tumors grew leaky blood vessels with perturbed pericyte-endothelial cell-cell interactions...... and deficient perivascular deposition of ECM components. Conversely, tumor cell expression of NCAM in a fibrosarcoma model (T241) improved pericyte recruitment and increased perivascular deposition of ECM molecules. Together, these findings suggest that NCAM may limit tumor cell metastasis by stabilizing...... the microvessel wall. To directly address whether pericyte dysfunction increases the metastatic potential of solid tumors, we studied beta cell tumorigenesis in primary pericyte-deficient Pdgfb(ret/ret) mice. This resulted in beta tumor cell metastases in distant organs and local lymph nodes, demonstrating a role...

    A 61-year-old man presented with a rare pleural malignant mesothelioma of the spine manifesting as progressive weakness of the bilateral lower extremities, numbness in the body and both legs, and dysfunction of the bladder and bowel. He had previous occupational exposure to asbestos while working at a car repair shop and had undergone right panpleuropneumonectomy under a diagnosis of sarcomatous type mesothelioma in the right pleural space. Magnetic resonance imaging of the spine with gadolinium showed an enhanced intramedullary tumor at the T4 level. Operative findings disclosed the clouded and swollen right posterior nerve root, and the pial surface was covered by clouded arachnoid-like membrane. The removed part of the T4 posterior nerve root and intramedullary tumor revealed malignant mesothelioma with invasion spreading along the posterior nerve root. He died of respiratory failure 3 months after the diagnosis. This case shows that spinal metastasis must be considered if a patient with pleural malignant mesothelioma shows neurological worsening and neuroimaging shows an abnormal lesion in the thoracic spinal cord. However, the patient's neurological condition is very difficult to improve in the presence of spinal cord infiltration.

  16. Metastasis of Laryngeal Squamous Cell Carcinoma to Bilateral Thigh Muscles

    2014-01-01

    Full Text Available Importance. Laryngeal cancer infrequently results in distant metastases, but metastasis to skeletal muscle is extremely uncommon. Observations. A 55-year-old male presenting with progressive dyspnea and hoarseness was found to have Stage IVA T4aN2cM0 laryngeal cancer and eventually underwent total laryngectomy. Before the patient could be started on adjuvant chemoradiation, the patient developed masses on both thighs. Biopsy revealed metastatic squamous cell carcinoma consistent with the primary laryngeal cancer. He was offered palliative chemotherapy; however, he developed new soft tissue masses to the left of his stoma and in the prevertebral area one week later. He also had new cervical and supraclavicular nodes and a pathological compression fracture of L3. Patient died within 4 months of diagnosis. Conclusions. Distant metastasis such as skeletal metastasis portends a poor prognosis. Further studies are required to determine the best course of treatment in these patients.

  17. Raman spectroscopy of bone metastasis

    2012-02-01

    Raman spectroscopy of bone has been used to characterize chemical changes occurring in diseases such as osteoporosis, osteoarthritis and osteomyelitis. Metastasis of cancer into bone causes changes to bone quality that are similar to those observed in osteoporosis, such as decreased bone strength, but with an accelerated timeframe. In particular, osteolytic (bone degrading) lesions in bone metastasis have a marked effect on patient quality of life because of increased risk of fractures, pain, and hypercalcemia. We use Raman spectroscopy to examine bone from two different mouse models of osteolytic bone metastasis. Raman spectroscopy measures physicochemical information which cannot be obtained through standard biochemical and histological measurements. This study was reviewed and approved by the University of Michigan University Committee on the Care and Use of Animals. Two mouse models of prostate cancer bone metastasis, RM1 (n=3) and PC3-luc (n=4) were examined. Tibiae were injected with RM1 or PC3-luc cancer cells, while the contralateral tibiae received a placebo injection for use as controls. After 2 weeks of incubation, the mice were sacrificed and the tibiae were examined by Raman microspectroscopy (λ=785 nm). Spectroscopic markers corresponding to mineral stoichiometry, bone mineralization, and mineral crystallinity were compared in spectra from the cancerous and control tibiae. X-ray imaging of the tibia confirmed extensive osteolysis in the RM1 mice, with tumor invasion into adjoining soft tissue and moderate osteolysis in the PC3-luc mice. Raman spectroscopic markers indicate that osteolytic lesions are less mineralized than normal bone tissue, with an altered mineral stoichiometry and crystallinity.

    Full Text Available Papillary thyroid carcinoma is the most common form of differentiated thyroid carcinoma. It is generally confined to the neck with or without spread to regional lymph nodes. Metastatic thyroid carcinomas are uncommon and mainly include lung and bone. Metastases involving oral and maxillofacial region are extremely rare. We described a case of malar metastasis revealing a follicular variant of papillary thyroid carcinoma, presenting with pain and swelling of the left cheek in a 67-years-old female patient with an unspecified histological left lobo-isthmectomy medical history. To our knowledge, this is the first recorded instance of a malar metastasis from a follicular variant of papillary thyroid carcinoma.

    Transitional cell carcinoma (TCC) of the female urethra is a rare urological malignancy, and intracranial metastasis of this cancer has not yet been reported in the literature. This review is intended to present a case of multiple intracranial metastasis in a female patient with a remote history of primary urethral TCC. A 49-year-old woman, presented with a prolapsed mass in urethral orifice that was diagnosed as primary urethral TCC with distant lung and multiple bone metastases. The patient subsequently underwent chemotherapy under various regimens. A year later, the patient developed headache and vomiting which as was found to be due to multiple intracranial metastasis. The patient underwent surgical resection of the largest lesion located on the cerebellum, and consecutively gamma knife radiosurgery was performed for other small-sized lesions. Pathological examination of the resected mass revealed a metastatic carcinoma from a known urethral TCC. Serial work-up of systemic metastasis revealed concomitant aggravation of lung, spleen, and liver metastasis. The patient died of lung complication 2 months after the diagnosis of brain metastasis. To the best of our knowledge, this is the first reported case of cerebral metastasis from primary urethral TCC, with pathological confirmation. As shown in intracranial metastasis of other urinary tract carcinoma, this case occurred in the setting of uncontrolled systemic disease and led to dismal prognosis in spite of aggressive interventional modalities

    Apigenin is a natural flavonoid which possesses multiple anti-cancer properties such as anti-proliferation, anti-inflammation, and anti-metastasis in many types of cancers including colorectal cancer. Neural precursor cell expressed developmentally downregulated 9 (NEDD9) is a multi-domain scaffolding protein of the Cas family which has been shown to correlate with cancer metastasis and progression. The present study investigates the role of NEDD9 in apigenin-inhibited cell migration, invasion, and metastasis of colorectal adenocarcinoma DLD1 and SW480 cells. The results show that knockdown of NEDD9 inhibited cell migration, invasion, and metastasis and that overexpression of NEDD9 promoted cell migration and invasion of DLD1 cells and SW4890 cells. Apigenin treatment attenuated NEDD9 expression at protein level, resulting in reduced phosphorylations of FAK, Src, and Akt, leading to inhibition on cell migration, invasion, and metastasis of both DLD1 and SW480 cells. The present study has demonstrated that apigenin inhibits cell migration, invasion, and metastasis through NEDD9/Src/Akt cascade in colorectal cancer cells. NEDD9 may function as a biomarker for evaluation of cancer aggressiveness and for selection of therapeutic drugs against cancer progression. - Highlights: • Apigenin inhibits migration, invasion, and metastasis of colorectal cancer cells. • Apigenin downregulates NEDD9. • Apigenin decreases phosphorylations of FAK, Src, and Akt. • Apigenin inhibits cell migration, invasion, and metastasis through NEDD9/Src/Akt.

    Full Text Available Metastasization and distinction from mammary carcinoma is of great clinical importance because of different treatment modalities. Here, we discuss a case of stage IIIC ovarian serous carcinoma, presenting with bilateral axillary nodes metastasis after 25 months interval of its initial presentation. Increased serum CA-125 level caused clinical suspicion. Computed tomography scan of abdomen and pelvis showed no residual disease or any abdominal lymphadenopathy. Mammography of both breast were normal. Bilateral axillary nodes were noted. Guided fine needle aspiration cytology (FNAC and biopsy of ovarian carcinoma to axillary node is a rare event. Its recogn done. Cytomorphology revealed poorly differentiated carcinoma, compatible to that of primary ovarian tumor. Thus, metastatic carcinoma to axillary node from ovary was confirmed. This case illustrates a rare metastatic presentation of ovarian carcinoma and unequivocal role of FNAC to provide rapid diagnosis and preferred to be first line diagnostic procedure.

    Identifying subarachnoid metastatic disease (SAMD) in patients with primary central nervous system tumors is important in determining subsequent therapy. Myelography with CT follow-up has been the gold standard for this evaluation. It is an invasive procedure often performed with general anesthesia in children. Now that gadolinium MR imaging has become available, a comparison of these techniques has been initiated to determine their relative effectiveness in demonstrating SAMD in children. Ten children (seven male, aged 2-19 years) with primitive neuroectoderm tumor (n = 5), ependymoma (n = 2), glioblastoma multiforme (n = 1), diffuse low-grade astrocytoma (n = 1), and rhabdoid/teratoid tumors (n = 1) underwent simultaneous myelography/CT and gadolinium MR imaging. Results are presented

    Spinal metastases are rare in head and neck cancer. We present a rare case of vocal cord squamous cell cancer that metastasized to the spinal cord and cauda equina. A 63-year-old man presented with acute back pain and bilateral leg weakness 5 months after having a surgical treatment for moderately differentiated vocal cord squamous cell cancer (T2 N0 M0). Restaging F-FDG PET examination demonstrated a soft tissue mass with intense hypermetabolism in the distal spinal cord and a hypermetabolic leptomeningeal metastatic deposit at the L3 level. The findings were confirmed on MRI prior to treatment.

    Injuries to the spinal column and spinal cord frequently occur after high-energy mechanisms of injury, or with lower-energy mechanisms, in select patient populations like the elderly. A focused yet complete neurologic examination during the initial evaluation will guide subsequent diagnostic procedures and early supportive measures to help prevent further injury. For patients with injury to bone and/or ligaments, the initial focus should be spinal immobilization and prevention of inducing injury to the spinal cord. Spinal cord injury is associated with numerous life-threatening complications during the acute and long-term phases of care that all acute care surgeons must recognize. Published by Elsevier Inc.

  11. Spinal cord lesions - The rehabilitation perspective.

    2006-02-01

    The present study provides an overview of the spinal cord injury focusing mainly on aspects related to rehabilitation. Spinal cord injury affects young people in an active phase of life, determining severe handicaps. Most of the lesions are traumatic, caused by car accidents. Until fifty years ago, the survival of individuals with spinal cord injury was very reduced and the leading cause of death was renal failure. Due to developments in medical knowledge and technical advances, the survival rates have significantly improved. The causes of death have also changed being respiratory complications, particularly pneumonia, the leading causes. Immediately after a spinal cord lesion there is a phase of spinal shock which is characterized by flaccid paralysis and bladder and bowel retention. Progressively there is a return of the spinal cord automatism with the beginning of some reflex activities. Based on neurological evaluation it is pos-sible to predict motor and functional recovery and establish the rehabilitation program. We can consider three phases on the rehabilitation program: the first while the patient is still in bed, directed to prevent or treat complications due to immobility and begin sphincters reeducation; the second phase is intended to achieve wheelchair autonomy; the last phase is training in ortostatism. The rehabilitation program also comprises sports and recreational activities, psychological and social support in order to achieve an integral of the individual with a spinal cord injury. © 2006 Sociedade Portuguesa de Pneumologia/SPP.

    There is minimal and often conflicting data in the literature regarding the oblique cord of the forearm. The current study seeks to elucidate further the anatomy of this structure of the upper extremity. In adult cadavers, the oblique cord was observed for and, when found, measurements were made of it. Ranges of motion were carried out while observation of the oblique cord was made. An oblique cord was found on 52.6% of sides. Gantzer's muscle was found on 55% of sides and, when present, had attachment into the oblique cord on five sides. The oblique cord was present on 13 sides with a Gantzer's muscle. Of the 20 sides with an oblique cord, no Gantzer's muscle was found on 10. The mean length of the oblique cord was 3.4 cm. In the majority of specimens, this cord tapered from proximal to distal. The proximal, middle, and distal widths of this structure had means 9, 7, and 4 mm, respectively. The oblique cord was found to travel approximately 45 degrees from a line drawn through the ulna and more or less traveled perpendicular to the insertion site of the bicipital tendon. This ligament was lax in the neutral position and with pronation became lax in all specimens. The oblique cord progressively became taut with increased supination from the neutral position and was maximally taut with the forearm fully supinated. Tautness of this cord was also found with distal distraction of the radius. Following the transection of the oblique cord, no discernable difference was observed in regard to maximal supination of the forearm or distal distraction of the radius. No obvious instability of the proximal forearm was found following transection of the oblique cord. Functionally, although the oblique cord may resist supination, it is unlikely that this structure affords significant stability to the proximal forearm, as it was often absent, of a very small caliber, and based on our observations, following its transection, the amount of supination of the forearm did not increase

  14. Dural Metastasis Mimicking Meningioma: An Interesting Case

    Directory of Open Access Journals (Sweden)

    Hamzaini Abdul Hamid

    2009-01-01

    Full Text Available Dural metastasis is a rare entity in clinical practice. We report a case of dural metastasis secondary to thyroid carcinoma, which on both preoperative CT and MRI and at surgery had the typical appearance of a meningioma. Histopathological findings confirmed metastatic follicular thyroid carcinoma as a primary site. Although rare, dural metastases can mimic a meningioma. Our experience in this case has led us to consider metastasis as a differential diagnosis even when a meningioma is suspected. We believe that reporting of the case of dural metastasis mimicking a meningioma may help clinicians in future.

  13. Amniotomy and cord prolapse.

    Science.gov (United States)

    Cohain, Judy Slome

    2013-01-01

    Research shows that artificially rupturing the amniotic sac (amniotomy) can cause umbilical cord prolapse. Amniotomy became a routine part of obstetrical care with the introduction of active management, without evidence of benefit. In the 30 years since active management was introduced, the rate at which amniotomy causes umbilical cord prolapse has not been directly studied. Two controlled studies from Turkey from 2002 and 2006 are the only published studies that provide enough data to extract the rate at which cord prolapse follows amniotomy. They show that 1 cord prolapse results from every 300 amniotomies (0.3%). There is data suggesting amniotomy may also increase neonatal GBS infection, maternal pain and fetal blood loss if placental blood vessels are punctured.

  1. Pancreatic Metastasis from Prostate Cancer

    Directory of Open Access Journals (Sweden)

    Julian Jacob

    2010-01-01

    Full Text Available The pancreas is an unusual location for metastases from other primary cancers. Rarely, pancreatic metastases from kidney or colorectal cancers have been reported. However, a variety of other cancers may also spread to the pancreas. We report an exceptional case of pancreatic metastasis from prostate cancer. Differences in management between primary and secondary pancreatic tumors make recognition of metastases to the pancreas an objective of first importance. Knowledge of unusual locations for metastatic spread will reduce diagnostic delay and lead to a timely delivery of an appropriate treatment.

    Retinoblastoma is the most common primary intraocular tumor and more and more attention has been paid to the developing countries. This study was aimed to evaluate the clinical features, treatment, and prognosis of retinoblastoma patients with central nervous system (CNS) metastasis in Beijing Tongren Hospital, one of the largest tertiary eye centers in China. Clinical data of 31 consecutive retinoblastoma patients with CNS metastases, who were diagnosed at the Department of Pediatrics in Beijing Tongren Hospital between September 2005 and December 2015, were retrospective analyzed. The median age at presentation was 29 months (range from 5 to 108 months). Magnetic resonance imaging (MRI) results indicated that 16 patients (56.6%, 16/31) presented with meningeal involvement, 12 (38.7%, 12/31) presented with intracranial mass, 11 (35.5%, 11/31) presented with thickened optic nerve, and 5 (16.1%, 5/31) presented with concurrent meningeal and spinal cord membrane involvement. Retinoblastoma cells were detected in the cerebrospinal fluid (CSF) of 12 patients (44.4%, 12/27). Laboratory examinations on the blood and CSF were performed for 11 patients who had received six cycles of systemic chemotherapy, indicated that the serum level of neurone-specific enolase (NSE) after chemotherapy was significantly lower than that before chemotherapy (P < 0.05). At the end of the follow-up, 25 patients were dead with a median survival time of 6 months (1 d - 21 months), and 6 cases were alive and continued to receive treatment. Our results were basically consistent with previous reports in the developing countries, and it could be guidance for clinical treatment, prognosis and prevention of CNS metastases in retinoblastoma.

  5. Sphincter (ring muscle) gymnastics for spinal cord injured and spinal cord transected patients.

    Yom-Tov, S

    2000-07-01

    Sphincter gymnastics seem to be able to recruit central pattern generators--networks of neurons that generate motor patterns--through peripheral rhythmic stimuli and to activate them without supraspinal signals. This physical therapy method is thus suitable for treating spinal cord injured and spinal cord transected patients, for it can reach below the injured segment and feed signals into the central nervous system, thus activating vital organs. This article presents some observations and discusses a possible mechanism.

  6. Solitary splenic metastasis from ovarian carcinosarcoma: a case report

    Directory of Open Access Journals (Sweden)

    Gillespie Thomas

    2011-02-01

    Full Text Available Abstract Introduction Metastatic tumors to the spleen are rare but are usually found in conjunction with metastasis to other organs. The most common sources of splenic metastasis are breast, lung and colorectal cancers as well as melanoma and ovarian carcinoma. A solitary carcinosarcoma metastasis to the spleen of any origin is very rare. To the best of our knowledge, there are fewer than 30 reported cases of ovarian primary tumors with solitary metastasis to the spleen, and only three solitary primary carcinosarcomas to the spleen have been reported, of which one is female. We present what is, to the best of our knowledge, the first case of a solitary metastatic carcinosarcoma to the spleen arising from a primary ovarian carcinsarcoma. Case presentation A 72-year-old Hispanic woman status post-total abdominal hysterectomy for ovarian carcinosarcoma presented with complaints of early satiety and abdominal pain for the past two months with a 30-lb unintentional weight loss. An initial computed tomographic scan of her abdomen and pelvis revealed a 30 cm × 27 cm splenic mass with displacement of the left kidney, stomach and liver. The patient was found to have a solitary metastatic carcinosarcoma of the spleen with biphasic epithelial (carcinomatous and mesenchymal (sarcomatous elements consistent with carcinosarcoma. Conclusion Carcinosarcoma of the spleen is a rare tumor. Carcinosarcomas are a biphasic neoplasm comprising malignant epithelial and mesenchymal components arising from a stem cell capable of differentiation. They can arise anywhere in the female genital tract, most commonly from the endometrium. Even though it is rare, carcinosarcomas can metastasize to the spleen. This unique case of a solitary splenic metastasis from ovarian carcinosarcoma has particular interest in medicine, especially for the specialties of surgical oncology, pathology and hematology/oncology.

  7. Metastasis in nasal cavity as first symptom of a renal carcinoma

    2012-01-01

    The renal carcinoma of clear cells is the most frequent histological type. Metastasis is present in approximately 25-30 % of the patients in the diagnosis. The peculiar tendency of this carcinoma to make metastasis in not very usual areas, makes of this oncological process a primary tumour to keep in mind in the differential diagnosis of metastases as the first neoplasia manifestation. A not very frequent case is presented, with tumour in the left nasal cavity and recurrent epistaxis, secondary to metastasis of renal carcinoma as first symptom

  8. Utility of MR imaging in pediatric spinal cord injury

    Felsberg, G.J.; Tien, R.D.; Osumi, A.K.; Cardenas, C.A.

    1995-01-01

    We evaluated the utility of MR imaging in pediatric patients with acute and subacute spinal cord injuries. MR imaging of 22 pediatric patients with suspected traumatic spinal cord injuries was reviewed. MR findings were correlated with physical examination and compared to available radiographs and CT examinations performed at time of presentation. Twelve patients had abnormalities on MR imaging. Seven had spinal cord contusions; five contusions were hemorrhagic. Five of seven patients with cord contusion had normal radiographs and CT exams. Six patients with normal radiographs and CT examinations had abnormal MR studies revealing cord contusion, ligamentous injury, disc herniation, and epidural hematoma. MR is useful in initial evaluation of pediatric patients with spinal cord injuries and in prognosis of future neurologic function. In the setting of spinal cord symptomatology and negative radiographic studies, MR imaging should be performed. Surgically correctable causes of cord compression demonstrated by MR imaging include disc herniation, epidural hematoma, and retropulsed fracture fragments. The entity of spinal cord injury without radiographic abnormality is a diagnosis of exclusion which should only be made after radiologic investigation with radiographs, high-resolution thin-section CT, and MR imaging.

  9. Oncoprotein metastasis and its suppression revisited

    Directory of Open Access Journals (Sweden)

    Radulescu Razvan T

    2010-04-01

    Full Text Available Abstract The past two decades have witnessed an increasing appreciation of the role of the tumor microenvironment, of genetic and epigenetic alterations in normal cells adjacent to tumors and of the migration of normal cells with aberrant intrinsic properties in cancer pathophysiology. Aside from these insights, a novel concept termed "oncoprotein metastasis" (OPM has recently been advanced and proposed to reflect protein-based neoplastic phenomena that might occur even before any modifications relating to the morphology, location or (epigenetic outfit of cells during the malignant process. Here, evidence is presented that supports the OPM perception and thus should contribute not only to further rethink the definition of a normal cell, but also the treatment of cancer disease in the years to come.

  10. Ventricular metastasis resulting in disseminated intravascular coagulation

    Directory of Open Access Journals (Sweden)

    Davis Ian D

    2005-05-01

    Full Text Available Abstract Background Disseminated Intravascular Coagulation (DIC complicates up to 7% of malignancies, the commonest solid organ association being adenocarcinoma. Transitional Cell Carcinoma (TCC has rarely been associated with DIC. Case presentation A 74-year-old woman with TCC bladder and DIC was found to have a cardiac lesion suspicious for metastatic disease. The DIC improved with infusion of plasma and administration of Vitamin K, however the cardiac lesion was deemed inoperable and chemotherapy inappropriate; given the patients functional status. We postulate that direct activation of the coagulation cascade by the intraventricular metastasis probably triggered the coagulopathy in this patient. Conclusion Cardiac metastases should be considered in cancer patients with otherwise unexplained DIC. This may influence treatment choices.

    2012-09-01

    Enterobius vermicularis is responsible for a variety of diseases but rarely affects the liver. Accurate characterisation of suspected liver metastases is essential to avoid unnecessary surgery. In the presented case, following a diagnosis of rectal cancer, a solitary liver nodule was diagnosed as a liver metastasis due to typical radiological features and subsequently resected. At pathological assessment, however, a necrotic nodule containing E. vermicularis was identified. Solitary necrotic nodules of the liver are usually benign but misdiagnosed frequently as malignant due to radiological features. It is standard practice to diagnose colorectal liver metastases solely on radiological evidence. Without obtaining tissue prior to liver resection, misdiagnosis of solitary necrotic nodules of the liver will continue to occur.

  12. Asymptomatic Bladder Metastasis from Breast Cancer

    Directory of Open Access Journals (Sweden)

    Luigi Cormio

    2014-01-01

    Full Text Available Introduction. Breast cancer is the most common nondermatologic cancer in women. Common metastatic sites include lymph nodes, lung, liver, and bone. Metastases to the bladder are extremely rare, with all reported cases presenting with urinary symptoms. Case Report. Herein, we report the first case of completely asymptomatic bladder metastasis from breast cancer, occasionally revealed, 98 months after the initial diagnosis of lobular breast carcinoma, by a follow-up computed tomography scanning showing thickening of left bladder wall and grade II left hydronephrosis. A positive staining for estrogen and progesterone receptors was confirmed by immunohistochemistry. Discussion. The reported case confirms that bladder metastases from breast cancer tend to occur late after the diagnosis of the primary tumor and, for the first time, points out they can be asymptomatic. Conclusion. Such data support the need for careful follow-up and early intervention whenever such clinical situation is suspected.

    2011-01-01

    Purpose/Background: To report the clinical and radiographic features and treatment outcome of neuroendocrine tumor (carcinoid) metastasis to the orbit. Materials and Methods: Retrospective chart review of four cases. Results: Mean patient age at the time of diagnosis of the primary neuroendocrine tumor and orbital metastasis was 58 and 66 years, respectively, with a mean duration of 8 years between diagnosis of primary tumor and orbital metastasis. Primary neuroendocrine tumor sites were gastrointestinal tract (n = 2), lung (n = 1), and testicle (n = 1). The most common presenting symptom was diplopia (three cases). Magnetic resonance imaging revealed orbital tumor in all cases. Octreotide scan was positive in one case. Treatment was tumor excision in three cases followed by external beam radiotherapy in two cases and one patient was followed without treatment. Tumor cells showed immunoreactivity to chromogranin, synaptophysin, and neuron-specific enolase in all cases. Mean follow-up after orbital tumor diagnosis was 39 months. Three patients had known systemic extraorbital metastasis before orbital involvement (mean interval of 5.9 years) and one case had immediately after development of orbital metastasis. One patient had multiple recurrences of orbital metastasis and eventually underwent exenteration. Two patients died of disseminated metastasis between 2 and 3 years after diagnosis of orbital metastasis. Conclusion: All four patients with orbital metastasis from neuroendocine tumor had evidence of systemic extraorbital metastasis. Aggressive metastatic neuroendocine tumors of orbit can lead to local recurrence even after surgical excision and radiation. Imaging tests were helpful in allowing early diagnosis and for monitoring after treatment. PMID:22279400

    the biophysical state of the primary tumor cell. To determine the cytoskeletal dynamics they chose magnetic twisting cytometry, where the spontaneous motion of surface bound marker beads was measured, which is a measure for the cytoskeletal remodeling dynamics. The group of Katarina Wolf measured the stiffness of the cell nucleus because it is the largest and stiffest organelle, which may hinder the migration of invasive tumor cells through dense connective tissue [2]. They combined atomic force confocal microscopy for measurement of bulk nuclear stiffness (the inverse of the compressibility) with simultaneous visualization of the cantilever-nucleus contact as well as monitoring of the cell's fate. The dynamics of tissue topology such as the mixing of compartments during cancer invasion and metastasis were theoretically analyzed by Lance L Munn [3]. In particular, he presented a mathematical model of tissue repair and tumor growth based on collective cell migration that simulates a wide range of tumor behaviors using correct tissue compartmentalization and connectivity. In the future, the topological analysis could be helpful for tumor diagnosis or monitoring tumor therapy. The group of Cynthia A Reinhart-King analyzed how the topological guidance of a 3D tumor cell migration at an interface of collagen densities affects cell motility [4]. In particular, they mimicked the heterogeneities in density of the tumor stroma by preparing gels with an interface of high and low density collagen gels and investigated how this affects cell motility. The author's review paper details the effect of focal adhesion proteins such as focal adhesion kinase (FAK) on cell motility and how this effect is driven by mechanical alterations of cells expressing FAK compared to cells with FAK knock-out [5]. In particular, it focused on mechanical properties regulated by FAK in comparison to the mechano-regulating protein vinculin. This article highlights that both focal adhesion proteins

    Full Text Available Metastasis to the thyroid gland is very rare. Recently, we experienced a case of thyroid metastasis from breast cancer accompanying a papillary thyroid. A 51-year-old female patient presented with a palpated lymph node on her left lateral neck. The patient had undergone a left modified radical mastectomy followed by chemotherapy and hormonal therapy 12 years prior. Ultrasonography of the neck revealed a malignant looking nodule at the left thyroid lobe, measuring 0.9 × 0.9 cm, and several cystic nodules at the right thyroid lobe. Ultrasonography of the neck additionally revealed a malignant looking lymph node at the right level VI. Fine-needle aspiration of the left thyroid lobe resulted in a diagnosis of papillary thyroid carcinoma and that of the right level VI in Hurthle cell lesion. The patient had a total thyroidectomy with selective dissection of the left neck node. Pathologic assessment of the specimen revealed metastatic carcinoma from the breast carcinoma and papillary thyroid carcinoma. Although the thyroid gland is highly vascularized, metastasis of malignant tumors to the thyroid is relatively rare and detection of metastasis shows a low frequency. So a careful evaluation of thyroid tumor should be considered in a patient with a history of other malignancy.

  4. Metastasis within a metastasis to the thyroid: A rare phenomenon

    Directory of Open Access Journals (Sweden)

    Yin Ping Wong

    2017-01-01

    Full Text Available Metastatic disease involving the thyroid gland is uncommon. Solitary thyroid metastases from various primary sites particularly kidney, lung, and breast had been previously described. To the best of our knowledge, metastases from two topographically separate primary malignancies to the thyroid have never been documented hitherto. This is the first reported case of cancer-to-cancer metastasis involving an invasive breast carcinoma metastasized within a metastatic renal cell carcinoma in the nonneoplastic thyroid in a 58-year-old woman. Distinguishing a secondary thyroid metastases from a primary thyroid malignancy is utmost crucial as treatment differs. The possibility of tumor metastases from two separated primaries should always be considered in a tumor exhibiting malignant cell populations with two distinctive histomorphological appearances. The role of immunohistochemistry stains in equivocal cases cannot be overemphasized.

    Full Text Available Objective To study clinicopathological features, diagnosis, differential diagnosis and prognosis of mixed adenoneuroendocrine carcinoma (MANEC.  Methods One case of MANEC with brain metastasis was reported focusing on the following aspects: clinical manifestations, histopathological features and immunophenotypes, and the relevant literatures were reviewed.  Results A 35-year-old male presented headache and vomiting, and his head CT scan showed a lesion located in the right temporal lobe. The tumor was detected after separating the cerebral cortex during the surgery. The tumor diameter was 3 cm. The tumor was soft and rubbery with ill-defined margins, and rich in blood supply. Under optical microscopy, the tumor was consisted of small round cells of the same size, with focal tumor cells arranged around blood vessels in a pseudorosette manner or papillary manner with brisk mitotic activity. The boundary between tumor and brain tissue was ill-defined. By using immunohistochemical staining, the tumor cells were diffusely positive for synaptophysin (Syn and CD56, and negative for glial fibrillary acidic protein (GFAP, pan cytokeratin (PCK, CD3, CD20, vimentin (Vim, leukocyte common antigen (LCA, thyroid transcription factor-1 (TTF-1, S-100 protein (S-100, neurofilament (NF, nestin (Nes, CK5/6, CK8/18 and CD99. Ki-67 labeling index was about 62%. Sigmoidoscopy was performed later in another hospital and showed a mass in the patient's colon. The colon tumor was biphasic in appearance, and was consisted of two distinct components: isomorphic small round cells and low-middle differentiated adenocarcinoma cells. The small round tumor cells were diffusely positive for Syn and CD56, and negative for PCK. The adenocarcinoma cells showed opposite results.  Conclusions MANEC is a rare tumor, which is defined in 2010 by WHO Classification of Digestive, and to the best of our knowledge, MANEC of the colon with brain metastasis has never been described

    Full Text Available Gliosarcoma (GS is a rare and exceedingly malignant neoplasm of the central nervous system. It displays clinical features similar to glioblastoma, yet is histologically unique as it harbors both gliomatous and sarcomatous cellular components. Involvement of the neuroaxis is predominantly limited to the cerebral parenchyma and meninges. Primary GS of the spinal cord is rarely encountered. We report a case of a 54 year old male who presented with 2 months of progressive, bilateral lower extremity sensory deficits. Magnetic resonance imaging of the neuro-axis revealed multiple intradural lesions involving the cervical and thoracic spinal cord without evidence of intracranial involvement. Surgical resection of a dural based, extramedullary cervical lesion and two exophytic, intramedullary thoracic lesions revealed gliosarcoma, WHO grade IV. The patient died approximately 11 months after presentation. This report confirms that GS is not limited to supratentorial involvement and can primarily affect the spinal cord.

    Medulloblastoma (MB) is the most frequent malignant pediatric brain tumor. Current treatment includes surgery, radiation and chemotherapy. However, ongoing treatment in patients is further classified according to the presence or absence of metastasis. Since metastatic medulloblastoma are refractory to current treatments, there is need to identify novel biomarkers that could be used to reduce metastatic potential, and more importantly be targeted therapeutically. Previously, we showed that ionizing radiation-induced uPAR overexpression is associated with increased accumulation of β-catenin in the nucleus. We further demonstrated that uPAR protein act as cytoplasmic sequestration factor for a novel basic helix-loop-helix transcription factor, Hand1. Among the histological subtypes classical and desmoplastic subtypes account for the majority while large cell/anaplastic variant is most commonly associated with metastatic disease. In this present study using immunohistochemical approach and patient data mining for the first time, we demonstrated that Hand1 expression is observed to be downregulated in all the subtypes of medulloblastoma. Previously we showed that Hand1 overexpression regulated medulloblastoma angiogenesis and here we investigated the role of Hand1 in the context of Epithelial-Mesenchymal Transition (EMT). Moreover, UW228 and D283 cells overexpressing Hand1 demonstrated decreased-expression of mesenchymal markers (N-cadherin, β-catenin and SOX2); metastatic marker (SMA); and increased expression of epithelial marker (E-cadherin). Strikingly, human pluripotent stem cell antibody array showed that Hand1 overexpression resulted in substantial decrease in pluripotency markers (Nanog, Oct3/4, Otx2, Flk1) suggesting that Hand1 expression may be essential to attenuate the EMT and our findings underscore a novel role for Hand1 in medulloblastoma metastasis. - Highlights: • Hand1 expression is downregulated in Medulloblastoma. • Hand1 over expression reduce

    The aim of the present study was to estimate the total number of mast cells in the human umbilical cord. Using 50 microns-thick paraffin sections, made from a systematic random sample of umbilical cord, the total number of mast cells per cord was estimated using a combination of the optical...... disector and fractionated sampling. The mast cell of the human umbilical cord was found in Wharton's jelly, most frequently in close proximity to the three blood vessels. No consistent pattern of variation in mast cell numbers from the fetal end of the umbilical cord towards the placenta was seen....... The total number of mast cells found in the umbilical cord was 5,200,000 (median), range 2,800,000-16,800,000 (n = 7), that is 156,000 mast cells per gram umbilical cord (median), range 48,000-267,000. Thus, the umbilical cord constitutes an adequate source of mast cells for further investigation...

    The sternum is known as a relatively common site for bone metastases by a variety of malignant neoplasms. The usual finding is increased radiotracer uptake on bone scintigraphy, and cold metastasis is distinctly unusual. In addition, total non visualization of the sternum presenting as bone metastasis is extremely rare. We describe two cases with similar findings (absent sternum showing no activity of the sternal segments on bone scintigraphy), which corresponded to metastatic involvement. These findings were shown to be the first manifestation of hepatocellular carcinoma in one patient and bone metastasis in another patient with ovarian cancer.

    Full Text Available A 53–year-old man underwent right nephrectomy for a locally advanced renal cell carcinoma with concomitant resection of a solitary metastasis in the right lung. Ten years later, he presented with haematochezia caused by a tumour in the tail of pancreas, invading the transverse colon and the greater curvature of the stomach. The tumour was radically resected, and histological examination revealed a solitary metastasis of the previous renal cell carcinoma. This case illustrates a rare indication for pancreatic resection because of pancreatic metastasis.

    Full Text Available Endotracheal metastasis is a rare situation, usually associated with malignancies of breast and gastrointestinal tract, specially colon. Papillary carcinoma of thyroid commonly disseminates through lymphatic channels and tracheal involvement through vascular route is rarely reported. Here, we report a case of tracheal metastasis from papillary carcinoma of thyroid. The patient responded to external beam radiation therapy with cobalt 60 beams in a dose of 44 Gy followed by a 16 Gy boost. The patient is under followup and is presently asymptomatic. This paper adds to the repertoire of evidence in treatment of endotracheal metastasis.

    We present the case of a 41-year-old man with known large cell lung cancer who had undergone left pneumonectomy 7 months prior and who presented with a large intramuscular mass involving the posterior left thigh and upper calf. This thigh mass was ultimately surgically explored, and specimens yielded both Escherichia coli organisms and cells reflecting a skeletal muscle metastasis from the patient's known lung cancer. The patient was also found to have a rectal metastasis from his lung cancer. Intramuscular abscesses produced by gastrointestinal tract flora are a well-known presentation of colon cancer. To our knowledge, this is the first case report of the simultaneous occurrence of a skeletal muscle metastasis and an E. coli abscess in the same anatomic location. We believe the patient's rectal metastasis may have been the intermediate step in this process. (orig.)

    Full Text Available Cutaneous metastasis from laryngeal carcinoma is a rare occurrence. A 55-year-old male patient with supraglottic cancer was treated with concurrent chemoradiation. Eighteen months later, he presented with ulceroproliferative growth on dorsum of the right hand. Biopsy revealed metastatic squamous cell carcinoma. Further investigations revealed underlying bone destruction with lung metastasis. In view of poor general condition and widespread dissemination of disease, palliative radiotherapy was delivered to the hand of the patient. He achieved satisfactory palliation in form of pain relief, control of bleeding, and discharge. The present report serves to emphasize the importance of properly diagnosing metastatic spread to unusual sites. Such metastasis is rare and is associated with a poor prognosis. Treatment is usually aimed at providing pain relief in these patients with limited life expectancy. Hence, we present a case of extensive cutaneous metastasis from laryngeal carcinoma with review of the literature.

    Thyroid metastasis of lung cancer is rarely observed in clinical practice. The primary cancers which metastasize to the thyroid gland are mostly renal cell carcinoma, lung cancer, and breast cancer. Transient destructive thyrotoxicosis is caused by massive metastasis of extrathyroid tumors. We herein present a case report of a patient with small cell carcinoma of lung with metastasis to the thyroid and thyrotoxicosis due to toxic multinodular goiter. A 66-year-old man complained of swelling around the right side of the neck, dyspnea, progressive weight loss, and palpitation starting since 3 months before his admission. The patient was diagnosed with small cell carcinoma of lung with metastasis to the thyroid and thyrotoxicosis due to toxic multinodular goiter. The case report presented here illustrates the challenge of making a definitive and adequate diagnosis, particularly if the patient presents with 2 potential causes of thyrotoxicosis. Thyroid scintigraphy is an important tool for differential diagnosis of thyrotoxicosis.

    Paragangliomas are benign neoplasms that arise from the autonomic nervous system and the associated paraganglia. Although benign, they have been shown to possess metastatic potential. Involvement of the spine is rare. Even rarer is considered the involvement of the cervical spine. We report a case of a patient with a history of an extra-adrenal non-functional paraganglioma of the jugular foramen which was initially treated with intra-arterial embolization. After a 3-year disease-free follow-up, the patient was presented with symptoms of spinal cord compression due to spinal metastases in C2 and C3 vertebrae. The patient was then treated with surgical decompression and external beam radiation. Therapeutic management with additional treatment options is now under discussion by a multidisciplinary team. Paraganglioma of the jugular foramen with spinal metastasis is an uncommon presentation where increased physician awareness and long-term follow-up are mandatory for all patients with history of paraganglioma.

    Testicular tumours have many different manifestations, including hydrocele formation. Herein, we present an extremely rare case of testicular mesothelioma presenting with left hydrocele, but without risk factors. Left radical inguinal orchidectomy was performed, and pathological examination revealed a malignant mesothelioma of the tunica vaginalis of the testis. No infiltration of the spermatic cord was evident, and upon advanced radiological evaluation, no sign of metastasis was detected. Follow-up was still ongoing in our urology outpatient clinic at the time of this report. Although hydrocele is a simple and common condition that is easy to diagnose, a detailed investigation should be performed. Thus, when encountering a patient with hydrocele, the clinician should evaluate the possibility of the presence of an underlying testicular/paratesticular tumour, including a rare one such as mesothelioma of the tunica vaginalis.

    Full Text Available Abstract Background The characteristics of cervical lymphatic metastasis in nasopharyngeal carcinoma (NPC are not completely understood. As such, radiotherapy to the entire lymphatic of the neck bilaterally has been empirically practiced even in early stage disease, although not supported by clinical evidence. We studied the pattern and probability of nodal metastasis through a meta-analysis of published evidences, with an aim to establish an evidence-based guideline for selecting and delineation of clinical target volume of neck lymphatics for conformation radiation for NPC. Methods A literature search yielded an initial 411 original articles, and 13 studies with 2920 NPC cases staged via MRI were included in this analysis. The occurrence of nodal metastasis was calculated and analyzed according to the respective regional nodal levels. Results 85% of NPC cases presented with lymphadenopathy. The most commonly involved regions include retropharyngeal (69% and level II lymph nodes (70%. The overall probability of levels III, IV, and V nodal involvement are 45%, 11%, and 27%, respectively. Low-risk node groups included the supraclavicular, levels IA/IB and VI nodes, and parotid nodes with involvement rates at 3%, 0%, 3%, 0%, and 1%, respectively. Nodal metastases followed an orderly pattern and the probability of "skip" metastasis between levels varied between 0.5-7.9%. Conclusions Lymph node metastasis in NPC follows a predictable and orderly pattern. The rarity of metastasis in certain nodal groups and "skip" metastasis suggest that reduced treatment volume is feasible in conformal radiotherapy for NPC.

PTC patients who had tumors with a maximal diameter greater than 1 cm and clinically negative SMLNs were included in this study. Finally, a total of 217 patients who underwent total thyroidectomy with central compartment neck dissection (CND and elective superior mediastinal lymph node dissection (SMLND, with or without modified radical neck dissection (MRND and revisional CND, were included.Occult SMLN metastasis was present in 15.7% (34/217. Cytological classifications of tumor, BRAFV600E mutation, Tumor size, T-stage, perithyroidal extension, lymphovascular invasion, multifocality, and paratracheal pN(+ were not predictive of SMLN metastasis (P > .05, while revision surgery, pretracheal pN(+, and multiple lateral pN(+ were associated with SMLN metastasis. There were no major complications related to SMLND. Transient and permanent hypoparathyroidism was observed in 69 cases (31.8% and 8 cases (3.6%, respectively.Despite clinically negative SMLN in preoperative evaluation, SMLN metastasis can be predicted for patients with a PTC tumor size larger than 1 cm, pretracheal LN metastasis, multiple lateral metastasis, and revisional surgery.

    In colorectal cancer (CRC), metastatic spread is supposed to be mainly driven by tumor cells with stem cell features. Only about 1% of all CRC patients develop metastasis to the central nervous system (CNS). The present study intended to analyze the correlation between the expression of cancer stem cell markers and patterns of liver or CNS metastases. Immunohistochemistry for β-catenin, CD133, CD44 and the mismatch-repair markers hMLH1 and hMSH2 was applied to primary specimen of two CRC cohorts with CNS (n=29) and exclusive liver metastasis (n=36). Furthermore, mutation analysis for KRAS exon 2 and BRAF exon 15 was performed. The expression of nuclear β-catenin, CD44 and CD133 was associated with the development of liver metastasis, but not of CNS metastasis. CD133 expression was absent in CRC with solitary CNS metastasis. Combination of cancer stem cell markers revealed high discriminatory power for the prediction of different patterns of distant spread. KRAS mutation was more frequently detected in patients with CNS metastasis, but the mutational status of KRAS and BRAF failed to show correlation with clinico-pathological data or the results of immunohistochemistry. This study demonstrates that deregulation of Wnt/β-catenin-signaling and high-grade expression of cancer stem cell markers correlate with metastasis to the liver, but not to the CNS. These data implicate that in CRC other mechanisms than deregulation of Wnt/β-catenin-signaling and acquisition of cancer stemness are required for formation of CNS metastasis.

    The treatment of hepatic metastasis of colon cancer was in progress by new biochemical agents. Generally, a resection was the first alternative treatment against hepatic metastasis of colon cancer, but new antitumor agents were more effective than conventional antitumor agents. Disappearance of metastasis for colon cancer treated with only antitumor agents was commenced to report. We were experienced a case of transverse colon cancer without a recurrence lesion after five years from the resection of hepatic metastasis. A case was a 77-year-old man. He was operated against transverse colon cancer in February 2003. Pathological stage was ss, n0, Stage II. In April 2004, serum CEA was increased. CT examination was not detected a hepatic metastasis but ultrasound examination and MRI detected the metastasis at S7 lesion in the liver. In July 2004, he was admitted to S-1 and PSK until October 2004. In December 2004, the lesion of hepatic metastasis was reduced and serum CEA was decreased. But in September 2005, the metastatic lesion was re-grown. A resection for hepatic metastasis was executed in November 2005. After the resection for hepatic metastasis, he was admitted to UFT/ UZEL from January 2006 to October 2006. Present time( June 2011), the lesion of recurrence was not detected by several examinations (CT, MRI, Ultrasound etc).

SCS treatment consists of one or more leads implanted in the epidural space of the spinal canal, connected to an implantable pulse generator (IPG). Each lead carries...... a number of contacts capable of delivering a weak electrical current to the spinal cord, evoking a feeling of peripheral paresthesia. With correct indication and if implanted by an experienced implanter, success rates generally are in the range of about 50–75%. Common indications include complex regional...... is described in detail and illustrated with a series of intraoperative pictures. Finally, indications for SCS are discussed along with some of the controversies surrounding the therapy. Implications The reader is presented with a broad overview of spinal cord stimulation, including the historical...

    Massively parallel DNA sequencing technologies provide an unprecedented ability to screen entire genomes for genetic changes associated with tumor progression. Here we describe the genomic analyses of four DNA samples from an African-American patient with basal-like breast cancer: peripheral blood, the primary tumor, a brain metastasis, and a xenograft derived from the primary tumor. The metastasis contained two de novo mutations and a large deletion not present in the primary tumor, and was significantly enriched for 20 shared mutations. The xenograft retained all primary tumor mutations, and displayed a mutation enrichment pattern that paralleled the metastasis (16 of 20 genes). Two overlapping large deletions, encompassing CTNNA1, were present in all three tumor samples. The differential mutation frequencies and structural variation patterns in metastasis and xenograft compared to the primary tumor suggest that secondary tumors may arise from a minority of cells within the primary.

    To review the clinical features, treatment, outcome and survival of metastatic tumors of the orbit. Retrospective, non-comparative, chart review of 80 patients with orbital metastasis treated in four tertiary orbital centres in Australia. The study included 80 patients of which, 44 were male with a mean age of 60 years. Orbital involvement commonly presented late in a multisystemic disease; however, the orbit was the first presentation in 15% of the cases. Diplopia (48%), pain (42%), and visual loss (30%) were the commonest symptoms at presentation; whereas proptosis (63%), strabismus (62%), and visual loss (41%) were the most frequent clinical signs. Computed tomography commonly showed a solid enhancing mass (42 cases) located within the orbital fat (43%), or enlarging an extraocular muscle (28%). Breast carcinoma (29%), melanoma (20%), and prostatic cancer (13%) were the most frequent histological types. Treatment was often multi-disciplinary and modalities included radiotherapy, chemotherapy, hormone therapy, surgery, and immunotherapy. Survival was limited to 1.5 years after diagnosis independent of the histological type, with 29% of patients alive after 17 months follow-up. A high index of suspicion and appropriate intervention with histological diagnosis can help in the management and quality of life in patients with metastatic orbital disease. Overall survival is limited and we encountered statistical limitations proving differences in the survival based on the sub-type of primary tumour involved. Metastatic orbital melanoma presented a higher incidence when compared with previous studies, probably due to the increase frequency of skin found in the Australian population.

    The existence of non seminomatous mixed germ cell tumors of the testis is a frequent event in urologic oncology. Nevertheless, the presence of both components, seminomatous and non seminomatous, in a germ cell tumor is unusual. We present a case of pure classic seminoma of the testis with a lymph node metastasis of pure embryonal carcinoma, with confirmatory immuohistochemical study and clinical outcome of the patient. A 34-year-old man presented with 3 cm supraclavicular tumor. CT scan also revealed multiple metastases in lymph nodes, liver, kidney and left adrenal gland. Tumor markers were negative and the biopsy performed discovered a lymph node metastasis of embryonal carcinoma of probable testicular origin. Ultrasound revealed a 6 mm hypoechoic nodule in the right testis. Orchyectomy was performed and pathologic analysis demonstrated a tumor, 1 cm of diameter, histopathologically compatible with classical seminoma with pagetoid extension to rete testis. Albuginea and spermatic cord did not present neoplastic involvement. Currently the patient is being treated with chemotherapy. The interest of the case is to remark an unusual aggressive clinical presentation as well as to perform a bibliographic review with emphasis in the theories regarding heterogeneous differentiation and spontaneous regression of germ cell tumors of the testis.

    The spinal cord has an active role in the modulation and transmission of the neural signals traveling between the body and the brain. Recent advancements in functional magnetic resonance imaging (fMRI) have made the in vivo examination of spinal cord function in humans now possible. This technology has been recently extended to the investigation of resting state functional networks in the spinal cord, leading to the identification of distinct patterns of spinal cord functional connectivity. In this study, we expand on the previous work and further investigate resting state cervical spinal cord functional connectivity in healthy participants (n = 15) using high resolution imaging coupled with both seed-based functional connectivity analyses and graph theory-based metrics. Within spinal cord segment functional connectivity was present between the left and right ventral horns (bilateral motor network), left and right dorsal horns (bilateral sensory network), and the ipsilateral ventral and dorsal horns (unilateral sensory-motor network). Functional connectivity between the spinal cord segments was less apparent with the connectivity centered at the region of interest and spanning spinal cord functional network was demonstrated to be state-dependent as thermal stimulation of the right ventrolateral forearm resulted in significant disruption of the bilateral sensory network, increased network global efficiency, and decreased network modularity.

    Papillary thyroid carcinoma frequently metastasises to the regional neck lymph nodes. However, cervical lymph node metastases as sole manifestation of occult papillary thyroid carcinoma are observed rarely. The authors report the case of a 52-year-old man presenting for slowly enlarging neck region and shortness of breath, with an insidious history for 15 years. Thyroid imaging showed a goitre predominantly of the right lobe, but histopathological finding revealed a multi-centric thyroid papillary carcinoma with lymph node metastasis. PMID:22605833

    The most common causes of intraocular metastases are breast and lung cancers, although many other neoplasms can metastasize to the eye. Most of the metastases are located in the posterior pole and the choroid is more often involved than the retina. We present a case of a choroidal metastasis from a papillary carcinoma of the thyroid, associated with a massive subretinal hemorrhage. Findings with color Doppler ultrasound are emphasized.

    Mavani, Sandip B.; Nadkarni, Trimurti D.; Goel, Naina A.

    2013-01-01

    A 46-year-old male presented with progressive paraparesis and sensory impairment in both lower limbs since 2 months. He had urinary and bowel incontinence. On examination he had flaccid paraplegia with a sensory level at 11th dorsal vertebral level. Magnetic resonance imaging (MRI) scans of the lumbosacral spine showed an enhancing intramedullary lesion in the conus. The patient underwent excision of the conus mass. Histopathology confirmed the tumor to represent a poorly differentiated metastatic carcinoma from an unknown primary. A positron emission tomography-computed tomography (PET-CT) scan of the whole body revealed hypermetabolic activity in the hilum of the right lung confirmed to be a lung carcinoma on a CT-guided biopsy. The patient was undergoing chemoradiation at 1 month follow-up. The author's literature search has yielded only four other case reports of conus metastasis of which only one is in English literature. The present case report and review of literature are presented. PMID:24381457

    CONTEXT: Thyroid metastasis from pancreatic adenocarcinoma is extremely rare, with only two previous cases in the literature. We report a case of pancreatic adenocarcinoma metastasising to the thyroid. We review the incidence, diagnosis, and management of this rare occurrence. CASE REPORT: A 38-year-old man with a synchronous 6-month history of thyroid swelling, presented with epigastric pain and signs of obstructive jaundice. He was investigated by abdominal computerised tomography and endoscopic retrograde cholangiopancreatography. The diagnosis of pancreatic neoplasm was made. His thyroid neoplasm was investigated at another tertiary centre and thought to be a papillary neoplasm. He underwent a pancreaticoduodenectomy and recovered well post-operatively. Eight weeks later he had a total thyroidectomy. Histology confirmed that the thyroid mass was both morphologically and immunophenotypically similar to the pancreatic neoplasm. CONCLUSION: This case demonstrates the importance of a full investigation when a patient with suspected neoplastic history presents with a thyroid nodule. We outline the crucial role that immunohistochemistry plays in detecting and classifying primary and secondary thyroid neoplasms. The detection of a solitary thyroid metastasis from pancreatic adenocarcinoma may indicate a poor prognosis, and it is debatable whether resection of the primary should be undertaken when it presents with a solitary metastasis.

    2000-04-01

    We report a case of severe asthma initially considered as cortico-resistant. Clinical analysis of dyspneic attacks demonstrated they were atypical, sometimes associated with dysphonia and syncopes. Severity of clinical presentation was discordant with lung function tests. The diagnosis of vocal cord dysfunction was confirmed by ENT specialized examination. It showed paradoxal inspiratory adduction of the vocal cords triggered by exercise. Treatment remained however difficult, based on speech therapy, relaxation and psychotherapy. This observation underlines the influence of searching a vocal cord dysfunction in cortico-dependent asthma, especially if clinical presentation is atypical. Treatment of this condition may allow to decrease steroid treatment in such patients.

  18. Spinal metastasis of medulloblastoma in adults: A case report

    Directory of Open Access Journals (Sweden)

    Živković Nenad

    2014-01-01

    Full Text Available Introduction. Medulloblastoma is a primitive neuro-ectodermal malignant tumor most commonly seen in childhood and rarely and uncommonly in adult age. Treatment consists of surgery followed by radiotherapy. In the case of a relapse there is no overall accepted treatment. Tumor metastasis can be seen along the neural axis, lymph nodes, soft tissues, bones and distant organs. Case Outline. In this paper we present a 45-year-old female patient with a thoraco-spinal extramedullary metastatic medulloblastoma and progressive neurological deterioration seen 11 months after the first operation and description of magnetic resonance and intraoperative finding. Conclusion. Although rare, the presence of metastasis is a poor prognostic factor. The treatment options for patients with metastases are limited and their prognosis continues to remain poor.

    2014-01-01

    Splenic metastasis is extremely rare and are usually found in conjunction with metastasis of other organs. In addition, late recurrence even after 10 years of operation is very unusual. The most common sources of splenic metastasis are lung, colonrectal, melanoma, breast and ovarian carcinoma. We present a case of 67 year old woman who was admitted to our department with a solitary splenic metastases after hysterectomy with bilateral salpingo-oophorectomy for ovaric carcinoma 10 years ago. In conclusion, solitary splenic metastasis are very rare and the incidence of the reported cases in the medical literature is increasing. The treatment of choice is laparoscopic splenectomy that must be followed by chemotherapy in order to prevent the development of other possible micrometastases.

    Papillary thyroid carcinoma is rarely associated with metastatic disease. The most common sites of metastasis are the lungs and bones, while only few cases of ovarian metastasis are described in literature. We report the case of a 51 years old woman, treated 9 years before for papillary thyroid carcinoma, presenting to our Institute with a pelvic ovarian mass revealed by ultrasound imaging. After bilateral salpingo-oophorectomy, the histologic examination detected a left ovarian metastasis from papillary thyroid carcinoma. Even if the diagnosis of ovarian metastasis from thyroid carcinoma is often controversial, it should be considered when a woman with an ovarian lesion of unknown origin, has a personal history of malignant thyroid disease.

    Thyroid metastasis of soft tissue sarcoma is very rare, and the diagnosis is especially difficult when only a single lesion is present. A 50-year-old man was diagnosed with myxoid liposarcoma of the right thigh and treated with wide resection. Two and a half years after the surgery, a growing low-density area was incidentally observed in the right lobe of his thyroid gland on follow-up chest computed tomography. Fine needle aspiration biopsy was performed twice, and the thyroid mass was suspected of being a sarcoma metastasis. He was treated by hemithyroidectomy, and the lesion was pathologically confirmed as a metastasis of myxoid liposarcoma. We experienced single thyroid gland metastasis in patients with myxoid liposarcoma in whom a growing mass is observed in the thyroid gland after radical surgery of the primary site.

    Arctigenin (ARC) has been shown to have an anti-cancer effect in various cell types and tissues. However, there have been no studies concerning metastatic colorectal cancer (CRC). In this study, we investigated the anti-metastatic properties of ARC on colorectal metastasis and present a potential candidate drug. ARC induced cell cycle arrest and apoptosis in CT26 cells through the intrinsic apoptotic pathway via MAPKs signaling. In several metastatic phenotypes, ARC controlled epithelial-mesenchymal transition (EMT) through increasing the expression of epithelial marker E-cadherin and decreasing the expressions of mesenchymal markers; N-cadherin, vimentin, β-catenin, and Snail. Moreover, ARC inhibited migration and invasion through reducing of matrix metalloproteinase-2 (MMP-2) and MMP-9 expressions. In an experimental metastasis model, ARC significantly inhibited lung metastasis of CT26 cells. Taken together, our study demonstrates the inhibitory effects of ARC on colorectal metastasis.

    2012-01-01

    Full Text Available Renal cell carcinoma (RCC has high metastatic potential, which requires early diagnosis to optimize the chance of cure. Metastasis of RCC to the head and neck region is less common and metastasis to the buccal mucosa is extremely rare. This phenomenon occurs mostly in patients with generalized dissemination, especially with lung metastases. In this article we report a case of buccal mucosa metastasis from RCC in a 65-year-old man who presented 19 years after undergoing a left radical nephrectomy for clear cell RCC. Surgical excision of the buccal lesion was performed without evidence of recurrence or new metastatic lesions after 6 years of followup. To our knowledge, this is the first case of metastasis to the buccal mucosa from a RCC reported in the literature.

    The thyroid gland is a relatively uncommon site for a metastatic disease, although it is richly supplied with blood. The metastases may originate from various primary sites, mainly kidney, lung, head and neck, and breast. Thyroid metastasis from cervical carcinomas is extremely rare; and only a few cases have been previously reported in the literature. In patient with thyroid nodules and an oncological history, the possibility of thyroid metastasis should be seriously considered. Despite the rarity of the metastasis of cervical carcinoma to the thyroid, it is difficult to say appropriate treatment approach for these lesions. When managing such patients, decision-making should balance the possibility of gaining long-term survival against estimation of the aggressiveness of the disease and its possible complications. Here, a case of thyroid metastasis from a squamous cell carcinoma of the uterine cervix presenting with cervical mass and difficulty in swallowing and its treatment is reported.

    ipsilateral level 1-2 nodal regions (11/13). Patients with nodal relapse had a significantly higher risk of distant metastasis on both univariate (p = 0.02) and multivariate analysis (hazard ratio = 4.5, p = 0.006). The 5-year actuarial risk of distant relapse was 29% for patients with neck control versus 81% for patients with neck failure. There was also a trend for decreased survival with nodal relapse. The 5-year actuarial survival was 37% for patients with neck control and 0% for patients with neck relapse. Conclusion: The overall incidence of lymph node involvement at diagnosis in patients with maxillary sinus carcinoma was 9%. Following treatment, the 5-year risk of nodal relapse was 12%. SCC histology was associated with a high incidence of initial nodal involvement and nodal relapse. None of the patients presenting with SCC histology and N0 necks had nodal relapse after elective neck irradiation. Patients who had nodal relapse had a higher risk of distant metastasis and poorer survival. Therefore, our present policy is to consider elective neck irradiation in patients with T3-4 SCC of the maxillary sinus

    Metastasis to the thyroid gland from nonthyroid sites is an uncommon clinical presentation in surgical practice. The aim of this review was to assess its incidence management and outcomes. A literature review was performed to identify reports of metastases to the thyroid gland. Both clinical and autopsy series were included. Metastases to the gland may be discovered at the time of diagnosis of the primary tumor, after preoperative investigation of a neck mass, or on histologic examination of a thyroidectomy specimen. The most common primary tumors in autopsy studies are from the lung. In clinical series, renal cell carcinoma is most common. For patients with widespread metastases in the setting of an aggressive malignancy, surgery is rarely indicated. However, when patients present with an isolated metastasis diagnosed during follow-up of indolent disease, surgery may achieve control of the central neck and even long-term cure. Other prognosticators include features of the primary tumor, time interval between initial diagnosis and metastasis, and extrathyroid extent of disease. In patients with thyroid metastases, communication among clinicians treating the thyroid and the index primary tumor is essential. The setting is complex, and decisions must be made considering the features of the primary tumor, overall burden of metastases, and comorbidities. Careful balancing of these factors influences individualized approaches.

    Nineteen patients with suspected spinal cord tumors were imaged with T1- and T2-weighted sequences before and after the administration of Gd-DTPA (0.1 mmol/kg). Eleven of the 19 patients had spinal cord tumors (three unproven). Eight of 11 patients had intramedullary tumors (four astrocytomas, two ependymomas) and two had extra-medullary tumors (one meningioma, one metastatic melanoma). Other lesions studied include idiopathic syringomyelia (two), spinal arteriovenous malformation (AVM) (one), posttraumatic arachnoiditis (one), and cord infarct (one). All of the tumors enhanced after the administration of Gd-DTPA. Spinal cord enhancement was also noted in association with a spinal cord AVM, a suspected cord infarct, and in the patient with severe arachnoiditis. No enhancement was present in patients with idiopathic or posttraumatic syringomyelia or in the three normal patients. In six of the patients, enhancement was critical in confirming disease that was questionable on the precontrast MR images. Gadolinium enhancement allowed differentiation of tumor from postoperative changes in two patients with spinal cord tumors. Enhanced images localized the lesion more accurately than precontrast MR images in eight patients. In four patients a lesion could only be detected after the administration of contrast. The postcontrast images better defined the margin of tumor from surrounding edema, operative scarring, and cord cavitation. The AVM case had enhancement of slowly flowing veins with Gd-DTPA posterior to an ischemic cord segment. Gd-DTPA enhancement is extremely useful in the detection and therapeutic assessment of spinal cord tumors; however, enhancement is not specific for tumors and should be interpreted in light of the clinical setting

    In treatment of cancer, distant metastases are important limiting factor because an estimated 50% of all cancer patients will develop metastases, and the metastases are major causing of cancer treatment failure. Recently a few reports indicated {gamma}-radiation induced an increase of invasiveness of several cancer cells. In this study, we had tried to show the possibility that radiation could also induce metastasis in vivo system. To prove our hypothesis, we constructed primary tumor by using C6-TL transfectant cell line expressing HSV1-tk and firefly luciferase (fLuc), and then {gamma}-radiation was treated to xenografts locally. Treatment of {gamma}-radiation to primary C6-TL xenografts of mice reduced size of xenografts and elongated survival of mice than those of mock control mice. But we also show that {gamma}-radiation treatment was followed by the growth of dormant metastases in various organs including lung and intestine after 2-4 weeks of {gamma}-radiation treatment. When bioluminescence imaging indicated growth of tumor in organs in mice, we sacrificed the mice and repeat acquired bioluminescence imaging after repeatedly. These images presented tumor growth locations exactly in organs. Because metastatic tumor candidates have morphology of foci, biopsies were performed for histological analysis or PCR analysis to confirm metastases. In most foci, histological analysis indicated several features of typical cancer tissue and PCR analysis showed present of fLuc gene in metastases. Detection of fLuc gene in metastases indicated these foci were originated from primary C6-TL xenografts, and the results suggest that {gamma}-radiation could promote metastasis in vivo as well as in vitro system. Although we need to understand changes of intracellular signaling or physiological phenomena of the radiation-induced metastasis yet, these results also imply that {gamma}-radiation treatment only to cancer patients need to pay attention carefully, and development of new

    Background and purpose: Early stage vocal cord carcinomas are usually cured by radiation therapy despite the use of portals that exclude the cervical lymph nodes. We investigated whether the lymphatic vessel density (LVD) of vocal cord carcinomas differs from that of other head and neck carcinomas. Patients and methods: Deparaffinized tissue from tumors of 60 patients diagnosed with head and neck squamous cell carcinoma (HNSCC) were immunostained for LYVE-1, a novel lymphatic vessel marker. Twenty-two had vocal cord carcinoma. Tumor blood vessel density (BVD) was assessed using immunostaining for CD31. Results: Tumor overall LVD, including both intra- and peritumoral lymph vessels, was 10-fold lower than the BVD (5 counts/mm 2 vs. 52 mm -2 , respectively). A high LVD was associated with a high BVD (P=.002), but neither was associated with the tumor size. Both tumor LVD and BVD were lower in vocal cord carcinomas than in HNSCCs arising at other sites (median, 0 vs. 7 mm -2 , P=.016; and median, 36 vs. 52 mm -2 , P=.006, respectively). Only one vocal cord carcinoma was associated with a regional metastasis at the time of the diagnosis. Among the rest of the cases tumor size was a better predictor for the presence of regional metastases than tumor BVD or LVD in a logistic regression model (odds ratio 2.2, 95% CI 1.1-4.5). Conclusion: Vocal cord carcinomas have a low lymph vessel density as compared with HNSCCs arising at other sites

    Full Text Available Metastatic tumors account for 1% of all oral malignancies. Metastasis to jaw bones is common, particularly in the mandible, rare in the oral soft tissues, and account for only 0.1% of oral malignancies. The majority of metastatic cases (70% reported in the literature have primary tumors located in the lung, breast, kidney, and colon. Metastasis is a biological complex process that involves detachment from the surrounding cells, regulation of cell motility, invasion, survival, proliferation, and evasion of the immune system. Clinical presentation of metastatic tumors is variable, which may create diagnostic dilemma or may lead to erroneous diagnosis. Metastatic tumors clinically mimic as dental infections. Metastasis to the oral soft tissue from lung cancer, especially gingiva is a rare condition. Metastasis to the gingiva can affect the oral function, speech, and nutrition. Most of the cases in the literature reported that lesion presented in oral soft tissues before the diagnosis of primary tumors. Here we report a case of 62-year-old male patient with metastasis from lung to the gingiva, where the metastasis was detected before primary tumor.

    An important image processing step in spinal cord magnetic resonance imaging is the ability to reliably and accurately segment grey and white matter for tissue specific analysis. There are several semi- or fully-automated segmentation methods for cervical cord cross-sectional area measurement with an excellent performance close or equal to the manual segmentation. However, grey matter segmentation is still challenging due to small cross-sectional size and shape, and active research is being conducted by several groups around the world in this field. Therefore a grey matter spinal cord segmentation challenge was organised to test different capabilities of various methods using the same multi-centre and multi-vendor dataset acquired with distinct 3D gradient-echo sequences. This challenge aimed to characterize the state-of-the-art in the field as well as identifying new opportunities for future improvements. Six different spinal cord grey matter segmentation methods developed independently by various research groups across the world and their performance were compared to manual segmentation outcomes, the present gold-standard. All algorithms provided good overall results for detecting the grey matter butterfly, albeit with variable performance in certain quality-of-segmentation metrics. The data have been made publicly available and the challenge web site remains open to new submissions. No modifications were introduced to any of the presented methods as a result of this challenge for the purposes of this publication. Copyright © 2017 The Authors. Published by Elsevier Inc.

    Primary spinal cord tumours can lead to severe neurological complications and even death. Pregnant women often complain of discomfort of the lower limbs, which is usually caused by sciatica. Here we present the case of a pregnant woman, who was initially considered to have sciatica, but was finally diagnosed with a primary intramedullary spinal cord tumour. A 28-year-old pregnant woman presented to our hospital with inexplicable numbness in her lower limbs. She was initially considered to have sciatica, but acute deterioration of neurological symptoms and plain magnetic resonance imaging (MRI) findings suggested malignancy. The patient was finally diagnosed with a primary intramedullary spinal cord tumour at the C3-Th5 region. An emergency caesarean section was performed, after which the spinal cord lesion was evaluated using contrast-enhanced MRI, positron emission tomography with 2-deoxy-2-[fluorine-18] fluoro-d-glucose integrated with computed tomography, and spinal angiography, and further treatment was initiated. However, while the patient's spinal cord tumour surgery was performed in early postpartum, her paraplegia and bladder and rectal disturbances remained unchanged even 1 year after surgery. Because of the low incidence of spinal cord tumours during pregnancy, no definite reports have been published on the treatment of pregnant patients with spinal cord tumours. Although safe imaging tests during pregnancy are limited, intervention in such patients should be performed as early as possible to avoid irreversible neurological deterioration.

    Full Text Available Inter epididymal testicular torsion of the spermatic cord is extremely rare and usually diagnosed at surgery. We present an unusual case of spermatic cord torsion in a 14-year-old male patient. It is important to highlight that the torsion occurred only on the distal half of the epididymis leaving the head untwisted and edematous. In addition, the fact that this condition was painless made this case extremely rare and motivated our presentation.

    This paper reports on sequential MR images and neurologic findings that were correlated in 40 acute spinal cord injuries. Within 1 week after injury, frequent initial MR changes appeared isointense on both T1- and T2-weighted images and isointense on T1- and hyperintense on T2-weighted images. After 2 months, hypointensity appeared on T1-weighted images and hyperintensity persisted or appeared on T2-weighted images. Clinical improvements were observed in patients with isointensity on both T1- and T2-weighted images at the initial examination. A larger area of hyperintensity on subsequent T2-weighted images was correlated with no neurologic improvement. MR findings were good indicators of the spinal cord injury

    Full Text Available Pain, which remains largely unsolved, is one of the most crucial problems for spinal cord injury patients. Due to sensory problems, as well as motor dysfunctions, spinal cord injury research has proven to be complex and difficult. Furthermore, many types of pain are associated with spinal cord injury, such as neuropathic, visceral, and musculoskeletal pain. Many animal models of spinal cord injury exist to emulate clinical situations, which could help to determine common mechanisms of pathology. However, results can be easily misunderstood and falsely interpreted. Therefore, it is important to fully understand the symptoms of human spinal cord injury, as well as the various spinal cord injury models and the possible pathologies. The present paper summarizes results from animal models of spinal cord injury, as well as the most effective use of these models.

    Cauda equina syndrome (CES) may be caused by tumor, herniated disc, trauma and spinal infections. However, CES due to occult lung cancer has not been reported in the literature. A 50-year-old man presented with a subacute CES caused by an intradural metastasis of an adenocarcinoma of the lung to the lumbosacral cauda fibers. His lumbosacral magnetic resonance imaging (MRI), showed a well-demarcated, intradural extramedullary mass lesion resembling a neurinoma at the L4/5 level. The patient underwent an L4-L5 laminectomy. The operative findings were also suggestive of neurinoma with involvement of three nerve roots, and a well-demarcated tumor without infiltration into the subarachnoid space. Although the findings of the operation were suggestive of neurinoma, final pathological diagnosis revealed metastatic carcinoma. Immunohistochemistry revealed clear cell adenocarcinoma metastasis. Chest X-ray and high resolution contrasted pulmonary computed tomography were normal. Positron emission tomography (PET) showed a lung mass, at the left apex. The patient was treated with chemotherapy and post-operative spinal radiotherapy was also performed. The CES resolved after the operation and the patient was followed up for 2 years with no recurrence. MRI of intradural cauda equina metastasis may be similar to that of intradural nerve sheath tumor. Surgery and postoperative radiotherapy may be effective for the treatment of CES due to lung carcinoma. Definitive diagnosis is by histopathological examination with immunohistochemistry. If the primary cancer cannot be detected by conventional radiological techniques, PET may be helpful.

    Highlights: •PCDH7 is overexpression in high bone metastatic MDA-MB-231 cells. •PCDH7 is up-regulation in bone metastatic breast cancer tissues. •Suppression of PCDH7 inhibits cell proliferation, migration, and invasion in vitro. •PCDH7 induces breast cancer bone metastasis in vivo. -- Abstract: Breast cancer had a propensity to metastasize to bone, resulting in serious skeletal complications associated with poor outcome. Previous study showed that Protocadherin-7 (PCDH7) play an important role in brain metastatic breast cancer, however, the role of PCDH7 in bone metastatic breast cancer has never been explored. In the present study, we found that PCDH7 expression was up-regulation in bone metastatic breast cancer tissues by real-time PCR and immunohistochemistry assays. Furthermore, suppression of PCDH7 inhibits breast cancer cell proliferation, migration, and invasion in vitro by MTT, scratch, and transwell assays. Most importantly, overexpression of PCDH7 promotes breast cancer cell proliferation and invasion in vitro, and formation of bone metastasis in vivo. These data provide an important insight into the role of PCDH7 in bone metastasis of breast cancer

    Do cancer cells escape the confinement of their original habitat in the primary tumor or are they forced out by ecologic changes in their home niche? Describing metastasis in terms of a simple one-way migration of cells from the primary to the target organs is an insufficient concept to cover the nuances of cancer spread. A diaspora is the scattering of people away from an established homeland. To date, "diaspora" has been a uniquely human term used by social scientists; however, the application of the diaspora concept to metastasis may yield new biologic insights as well as therapeutic paradigms. The diaspora paradigm takes into account, and models, several variables including: the quality of the primary tumor microenvironment, the fitness of individual cancer cell migrants as well as migrant populations, the rate of bidirectional migration of cancer and host cells between cancer sites, and the quality of the target microenvironments to establish metastatic sites. Ecologic scientific principles can be applied to the cancer diaspora to develop new therapeutic strategies. For example, ecologic traps - habitats that lead to the extinction of a species - can be developed to attract cancer cells to a place where they can be better exposed to treatments or to cells of the immune system for improved antigen presentation. Merging the social science concept of diaspora with ecologic and population sciences concepts can inform the cancer field to understand the biology of tumorigenesis and metastasis and inspire new ideas for therapy.

    Full Text Available Abstract Background Isolated splenic metastases from colorectal cancer are very rare and there are only 13 cases reported in the English literature so far. Most cases are asymptomatic and the diagnosis is usually made by imaging studies during the evaluation of rising CEA level postoperatively. Case presentation A 76-year-old man underwent an extended left hemicolectomy for synchronous colon cancers located at the left flexure and the sigmoid colon. The tumors were staged as IIIC (T3N2M0 clinically and the patient received adjuvant chemotherapy. During the first year follow-up period, the patient remained asymptomatic with normal levels of laboratory tests including CEA measurement. However, a gradually rising CEA level after the 14th postoperative month necessitated further imaging studies including computed tomography of the abdomen which revealed a mass in the spleen that was subsequently confirmed by 18FDG- PET scanning to be an isolated metastasis. The patient underwent splenectomy 17 months after his previous cancer surgery. Histological diagnosis confirmed a metastatic adenocarcinoma with no capsule invasion. After an uneventful postoperative period, the patient has been symptom-free during the one-year of follow-up with normal blood CEA levels, although he did not accept to receive any further adjuvant therapy. To the best of our knowledge, this 14th case of isolated splenic metastasis from colorectal carcinoma is also the first reported case of splenic metastasis demonstrated preoperatively by 18FDG PET-CT fusion scanning which revealed its solitary nature as well. Conclusion Isolated splenic metastasis is a rare finding in the follow-up of colorectal cancer patients and long-term survival can be achieved with splenectomy.

    2014-05-01

    Full Text Available Introduction: Ewing’s sarcoma (ES is the second most common bone tumor in children. Survival has not improved over the last decade and once pulmonary metastatic disease is present, survival is dismal. Mesenchymal stromal cell (MSC therapy has shown potential benefit for Kaposi's sarcoma; however, the role of progenitor cell therapies for cancer remains controversial. MSC treatment of ES or pulmonary metastatic disease has not been demonstrated. We have developed an orthotopic xenograft model of ES in which animals develop spontaneous pulmonary metastases. Within this model, we demonstrate the use of MSCs to target ES lung metastasis. Materials and MethodsHuman ES cells were transfected with luciferase and injected into the rib of nude mice. Development of pulmonary metastases was confirmed by imaging. After flow cytometry based characterization, MSC’s were injected into the tail vein of nude mice with established local ES tumor or pulmonary metastasis. Mice were treated with intravenous MSCs weekly followed by bioluminescent imaging.ResultsThe intravenous injection of MSCs in an ES model decreases the volume of pulmonary metastatic lesions; however, no effect on primary chest wall tumor size is observed. Thus verifying the MSC preferential homing to the lung. MSCs are found to ‘home to’ the pulmonary parenchyma and remain engrafted up to 5 days after delivery. DiscussionMSC treatment of ES slows growth of pulmonary metastasis. MSC’s have more affinity for pulmonary metastasis and can effect a greater decrease in tumor growth in the lungs compared to the primary tumor site

  8. Metachronous mediastinal lymph node metastasis from ascending colon cancer: A case report and literature review

    Kosuke Toda

    Full Text Available Introduction: Metachronous mediastinal lymph node metastasis without pulmonary metastasis is extremely rare in colorectal cancer, which makes the clinical diagnosis difficult and treatment strategy unclear. Prsentation of case: A case was a 59-year-old man, who had undergone right hemicolectomy for ascending colon cancer 2 years and 8 months previously, presented with enlarged mediastinal lymph nodes. 18F-fluorodeoxyglucose (FDG positron emission tomography revealed FDG was accumulated only into the mediastinal lymph nodes. Serum carcinoembryonic antigen (CEA level was within the normal range. Six months later, the size and FDG uptake of the mediastinal lymph nodes had increased. We assumed a possibility that the mediastinal lymph nodes were metastasized from ascending colon cancer and so performed thoracoscopic-assisted resection of the mediastinal lymph nodes. Histopathological analysis revealed the resected lymph nodes were filled with moderately differentiated adenocarcinoma and a diagnosis of mediastinal lymph nodes metastasis from previously-resected ascending colon cancer was made. The patient was postoperatively followed for more than 1 year and 8 months without any sign of recurrence. Discussion: Only 7 cases of metachronous mediastinal lymph node metastasis from colorectal cancer, including our case, have been reported in the English literature. It is difficult to clinically diagnose mediastinal lymph node metastasis. Conclusion: We report a rare case of metachronous mediastinal lymph node metastasis from ascending colon cancer with literature review. If the mediastinal lymph nodes are enlarged after colorectal cancer resection, we need to make a treatment strategy as well as a diagnostic approach considering the possibility of mediastinal lymph node metastasis.

    Bone is the single most frequent site for bone metastasis in breast cancer patients. Patients with bone-only metastasis have a fairly good prognosis when compared with patients with visceral disease. Nevertheless, cancer-induced bone disease carries an important risk of developing skeletal related events that impact quality of life (QoL). It is therefore particularly important to stratify patients according to their risk of developing bone metastasis. In this context, several risk factors have been studied, including demographic, clinicopathological, genetic, and metabolic factors. Most of them show conflicting or non-definitive associations and are not validated for clinical use. Nonetheless, tumour intrinsic subtype is widely accepted as a major risk factor for bone metastasis development and luminal breast cancer carries an increased risk for bone disease. Other factors such as gene signatures, expression of specific cytokines (such as bone sialoprotein and bone morphogenetic protein 7) or components of the extracellular matrix (like bone crosslinked C-telopeptide) might also influence the development of bone metastasis. Knowledge of risk factors related with bone disease is of paramount importance as it might be a prediction tool for triggering the use of targeted agents and allow for better patient selection for future clinical trials.

    Specify the epidemiological data on the acute spinal cord injuries and define a group of patients that could benefit from cellular transplantation therapy designed with the aim of repair and regeneration of damaged spinal cord tissues. Five years monocentric (Gui-de-Chauliac Hospital, Montpellier, France) retrospective analysis of patients suffering from spinal cord injury (SCI). Spinal cord injured-patients, defined as sensory-motor complete, underwent a clinical evaluation following American Spinal Injury Association (ASIA) and functional type 2 Spinal Cord Independence Measure (SCIM2) scorings as well as radiological evaluation through spinal cord magnetic resonance imaging (MRI). One hundred and fifty-seven medical records were reviewed and we selected and re-examined 20 patients with complete thoracic spinal cord lesion. Clinical and radiological evaluations of these patients demonstrated, in 75 % of the cases, an absence of clinical progression after a mean of 49months. Radiological abnormalities were constantly present in the initial (at the admission to hospital) and control (re-evaluation) MRI and no reliable predictive criteria of prognosis had been found. We compare our results to the literature and discuss advantages and limits of cellular transplantation strategies for these patients. Copyright © 2012 Elsevier Masson SAS. All rights reserved.

    Our purpose was to differentiate glioblastoma from metastasis using a single dynamic MR sequence to assess perfusion and permeability parameters. 24 patients with glioblastoma or cerebral metastasis with peritumoral oedema were recruited and explored with a 3 T MR unit. Post processing used DPTools software. Regions of interest were drawn around contrast enhancement to assess relative cerebral blood volume and permeability parameters. Around the contrast enhancement Glioblastoma present high rCBV with modification of the permeability, metastasis present slight modified rCBV without modification of permeability. In conclusion, peritumoral T2 hypersignal exploration associating morphological MR and functional MR parameters can help to differentiate cerebral metastasis from glioblastoma.

    The authors present results of in vivo measurements of the cervical canal and spinal cord. They indicate that tension in the spinal cord increases during flexion. They conclude that, as the dorsal approach avoids this increased tension of the spinal cord, the surgical treatment in chronic cervical myelopathy using this route seems to be preferable

This observational study serves to present a series of 46 cases of spermatic cord torsion whereby we hypothesize the identification of a clinical knot on scrotal examination as an important clinical aid in making a decision to surgical exploration in patients with acute and subacute SCT, especially in centers where imaging resources are unavailable.

    In this study, the authors aimed to identify prognostic factors after selective internal radiation therapy (SIRT) for colorectal cancer (CRC) liver metastasis. Forty-nine (28 male, 21 female; mean age: 64.6 ± 10.8) patients who received SIRT for CRC liver metastasis were studied. Effects of number (<5 vs. ≥5), maximum dimension, and standardized uptake value (SUV) of liver metastases, liver tumor load (<25% vs. 26%-50% vs. 51%-75%), presence of extrahepatic disease, and metabolic early response on overall survival were analyzed. Mean follow-up time was 44.1 ± 27.5 months. Overall survival time was calculated as 10.03 ± 1.61 (95% CI; 6.86-13.20) months. SUV (0.004) of liver metastases, early metabolic response (p = 0.015), and presence of extrahepatic metastasis (p = 0.001) were identified as significant factors influencing overall survival. The hazard ratio was 1:2.3 for the presence of extrahepatic metastasis and 1:2.7 for the absence of early metabolic response. These findings suggest that patients with CRC liver metastasis who have lower SUV at presentation and early metabolic response have better outcomes after SIRT.

    Full Text Available Background: The appropriate moment for clamping the umbilical cord is controversial. Immediate cord clamping (ICC is an item of active management of the third stage of labor (AMTSL. Unclamped umbilical cord may cause inconvenience in preterm neonates because they commonly need some levels of emergent services. Some studies revealed delayed cord clamping (DCC of preterm neonates results in better health conditions like lower rates of respiratory distress syndrome (RDS, less morbidities in labor room and lower risk of postpartum hemorrhage. The aim of the present study was to determine the effect of delayed umbilical cord clamping on premature neonatal outcomes. Materials and Methods: In this single‑center randomized control trial study, sixty premature neonates (gestational age ≤ 34 weeks were randomly assigned to ICC (cord clamped at 5–10 seconds or DCC (30–45 seconds groups and followed up in neonatal intensive care unit (NICU. Primary outcomes were 1st and 5th minute Apgar score, average of level of hematocrit after birth, intra ventricle hemorrhage and need some levels of resuscitation. Results: Differences in demographic characteristics were not statistically significant. After birth, neonates who had delayed clamping had significantly higher mean hematocrit after at 4-hour of birth (49.58+5.15gr/dl vs. 46.58+5.40gr/dlin DCC vs. ICC groups, respectively (P=0.031. Delayed cord clamping reduced the duration of need to nasal continues positive airway pressure (NCPAP (86.7% and 60.0% in ICC and DCC groups, respectively, P= 0.039. Attractively, the results showed lower incidence of clinical sepsis in delayed cord clamping neonates (53.3% vs. 23.3% in ICC and DCC groups, respectively, P=0.033. Conclusion: Prematurity complications might decrease by delay umbilical cord clamping which improve the hematocrit, duration of need to NCPAP and incidence of clinical sepsis. Furthermore, DCC may have no negative impact on neonatal resuscitation.

    Full Text Available Metastatic malignant mesothelioma of the pleura is uncommon at the time of initial diagnosis. The gastrointestinal lumen is rarely found at autopsy in patients with widespread disease. Here, we describe an extremely rare case of isolated duodenal metastasis of sarcomatoid mesothelioma of the pleura in a 73-year-old man, without memory of any direct exposure to asbestos. The possibility of gastrointestinal tract metastasis should be considered in the presence of anemia or positive occult blood test in patients with malignant pleural mesothelioma.

    Full Text Available Objective To summarize the clinical manifestations, imaging characteristics and experience of surgical treatment of spinal cord terminal syringomyelia with tethered cord syndrome (TCS.  Methods and Results Clinical data of 10 patients with spinal cord syringomyelia combined with TCS surgically treated under microscope from January 1999 to March 2014 in our hospital were retrospectively analyzed. There were 3 males and 7 females with average age of 15.06 years old (ranged from 2 to 35 years old. The course of disease ranged from 3 months to 20 years (average 42.17 months. Among those patients, one patient presented hydromyelia, 8 patients suffered from meningeal cyst within the sacral canal, and one patient were concurrent with sacral dermal sinus. The weakness of lower extremities, especially distal limbs, was the main clinical manifestation. Five patients were accompanied with bowel and bladder dysfunction and 5 patients with sensory disturbance below the level of syringomyelia, especially hypesthesia. Preoperative MRI showed conus medullaris disappeared at the end of spinal cord, and there was fluid signal in the lower spinal cord with hypo-intensity signal in T1WI and hyper-intensity signal in T2WI without enhancement. All patients underwent surgical procedures. Under microscope, filum terminale was cut off, drainage was performed, meningeal cyst within the sacral canal was removed, and tethered cord was released. The success rate of operations was 100%. The duration of surgery ranged from 1.52 to 3.07 h (average 2.15 h, with average intraoperative blood loss 220 ml (ranged from 100 to 410 ml. The tethering filum had been totally resected and histological examination showed typical filum tissue in all cases. No operative complication was found. Visual Analogue Scale (VAS score was decreased, and the lower limbs weakness as well as bowel and bladder dysfunction was gradually relieved after operation. The period of follow-up was ranged from 6

    Full Text Available Renal cell carcinoma is a common cancer, known for its aggressive behavior and ability to metastasize nearly every organ system in the body. While the cancer commonly spreads to a select few organs and metastasis usually develops within 5 years of diagnosis, there have been numerous case reports of atypical sites of metastasis and cases of relapse up to decades after treatment. We present a case a 65-year-old male who presented with right preauricular swelling 8 years after the initial diagnosis and right nephrectomy for clear cell renal cell cancer. We take a look at previous case reports with similar presentations.

    Lapsiwala, Samir B; Iskandar, Bermans J

    2004-10-01

    The management of adult-onset tethered cord syndrome (TCA) remains controversial, although the necessity of early surgery in children with TCS is well established. In this paper, we review the major publications that discuss the congenital tethered spinal cord (spina bifida occulta) presenting in adulthood. Data concerning acquired tethered cord from prior myelomeningocele repair were excluded. TCS in adults is an uncommon entity that can become symptomatic. The long-term surgical outcome after tethered cord release in this patient population is generally favorable, as most patients report improvement or stabilization of their symptoms. In addition, the overall post-operative complication rate is low. Although special consideration should be given to older patients with a poor general medical condition, it seems reasonable to recommend early surgical treatment in both symptomatic and asymptomatic adults.

  7. Gastrointestinal stromal tumor of the rectum with scapular metastasis: a case report

    2012-06-01

    Full Text Available Abstract Introduction Gastrointestinal stromal tumors are rare tumors. They commonly metastasize within the abdominal cavity, particularly to the liver. Less commonly, metastases can be found in the bone. Case presentation We here present a case of metastasis to the scapula in a 54-year-old Caucasian male patient with an advanced gastrointestinal stromal tumor, which was subsequently successfully treated with resection and sunitinib. Conclusion The present study is, to the best of our knowledge, the second to describe scapular metastasis of a gastrointestinal stromal tumor. Our patient was treated by scapulectomy. The overwhelming majority of scapular tumors are metastases that arise from soft tissue, hepatocellular and thyroid tumors. Gastrointestinal stromal tumor metastasis occurs rarely. Scapular surgery can successfully provide local control of the disease. After the surgery, patients should continue with medical treatment.

    Full Text Available Although extrahepatic metastases from hepatocellular carcinoma (HCC are present in only 5–15% of cases, they are certainly factors associated with poor prognosis. The main sites include lung, lymph nodes, bones, and adrenal glands, in descending order. Metastasis in the central nervous system is extremely rare, and the incidences vary from 0.6 to 1.7%. We report a case of a 54-year-old man previously diagnosed with alcohol-induced cirrhosis of the liver and HCC. The patient was admitted presenting progressive left hemiparesis and headache which started 2 days earlier, with no history of cranioencephalic trauma. After admission, cranial computed tomography revealed an intraparenchymal hemorrhage area with surrounding edema in the right frontal lobe. An angioresonance requested showed a large extra-axial mass lesion located in the right frontal region with well-defined contours and predominantly hypointense signal on T2 sequence. At first, the radiological findings suggested meningioma as the first diagnostic hypothesis. However, the patient underwent surgery. The tumor was completely removed, and the morphological and immunohistochemical findings were consistent with metastatic hepatocarcinoma associated with meningioma. In postoperative care, the patient did not recover from the left hemiparesis and manifested Broca’s aphasia. He had a survival time of 24 weeks, presenting acute liver failure as his cause of death. There is a lack of evidence supporting a specific management of patients with brain metastasis from HCC. Furthermore, there are no studies that evaluate different modalities of therapeutics in brain metastasis of HCC due to the rarity of this condition. Therefore, management must be individualized depending on probable prognostic factors in these patients.

    Full Text Available Tumor cells can persist undetectably for an extended period of time in primary tumors and in disseminated cancer cells. Very little is known about why and how these tumors persist for extended periods of time and then evolve to malignancy. The discovery of cancer stem cells (CSCs in human tumors challenges our current understanding of tumor recurrence, drug resistance, and metastasis, and opens up new research directions on how cancer cells are capable of switching from dormancy to malignancy. Although overlapping molecules and pathways have been reported to regulate the stem-like phenotype of CSCs and metastasis, accumulated evidence has suggested additional clonal diversity within the stem-like cancer cell subpopulation. This review will describe the current hypothesis linking CSCs and metastasis and summarize mechanisms important for metastatic CSCs to re-initiate tumors in the secondary sites. A better understanding of CSCs’ contribution to clinical tumor dormancy and metastasis will provide new therapeutic revenues to eradicate metastatic tumors and significantly reduce the mortality of cancer patients.

    Cerebral metastasis occur in 20 to 30 percent of patients with systemic cancer and are the most common type of intracranial tumor. The median survival of untreated patients is one month with a slightly longer survival in those treated with steroids. Patients treated with whole brain radiation therapy survive between 3 to 6 months. In selected cases survival can increase to 10 to 12 months with combination of surgery and radiotherapy or stereotactic radiosurgery alone or associated to radiotherapy. Most brain metastasis arise from lung, breast and melanomas. The most important criteria for selecting patients who will benefit from surgery or stereotactic radiosurgery are a Karnofsky score of 70 or more, systemic control of the cancer and absence of leptomeningeal involvement. Surgery is indicated in patients with a single lesion located in an accessible zone and stereotactic radiosurgery is indicated for lesions up to 3 cm of diameter, and in patients with up to 3 or 4 metastasis, no matter their location. The survival benefit of chemotherapy in brain metastasis has not been demonstrated

    In vitro replication of traumatic spinal cord injury is necessary to understand its biomechanics and to improve animal models. During a traumatic spinal cord injury, the spinal cord withstands an impaction at high velocity. In order to fully assess the impaction, the use of spinal canal occlusion sensor is necessary. A physical spinal cord surrogate is also often used to simulate the presence of the spinal cord and its surrounding structures. In this study, an instrumented physical spinal cord surrogate is presented and validated. The sensing is based on light transmission loss observed in embedded bare optical fibers subjected to bending. The instrumented surrogate exhibits similar mechanical properties under static compression compared to fresh porcine spinal cords. The instrumented surrogate has a compression sensing threshold of 40% that matches the smallest compression values leading to neurological injuries. The signal obtained from the sensor allows calculating the compression of the spinal cord surrogate with a maximum of 5% deviation. Excellent repeatability was also observed under repetitive loading. The proposed instrumented spinal cord surrogate is promising with satisfying mechanical properties and good sensing capability. It is the first attempt at proposing a method to assess the internal loads sustained by the spinal cord during a traumatic injury. Copyright © 2017 IPEM. Published by Elsevier Ltd.

    Brain metastases are the most commonly seen intracranial lesions in adults. What is more, meningiomas are the most common primary intracranial tumours after gliomas and their imaging characteristics are well known in both CT and MRI scans. However, there are lesions that can mimic meningiomas in imaging studies, including metastases of extracranial tumours, confronting us with a diagnostic and therapeutic challenge. We present the case of a patient with meningeal metastasis of a uterine leiomyosarcoma that was not known at the time of the surgical intervention. Copyright © 2017 Sociedad Española de Neurocirugía.

    Metastasis to the skeleton is uncommon in muscle-invasive carcinoma of the urinary bladder. When present, it most commonly involves the axial and proximal appendicular skeleton, and acrometastasis (metastasis to hand and foot) is very rare. We report a patient who developed a solitary metastatic lesion of the left metatarsal 2 weeks after radical cystectomy. The lack of suspicion and magnetic resonance imaging findings suggestive of inflammation led to a diagnosis of tubercular osteomyelitis and antitubercular therapy was started. The patient developed nodal metastasis and, because the foot lesion did not respond to treatment, fine needle aspiration cytology from it revealed poorly differentiated metastatic cancer.

    Full Text Available Background/Aims: Recurrent gene mutation has been identified by the analysis of exonic DNA from lung adenocarcinoma, but its progression has not been extensively profiled. The investigation of the mutational landscape of tumors provides new insights into cancer genome evolution and further discovers the interplay of somatic mutation, adaptation of clones to their environment and natural selection. Cancer development involves cycles of genomic damage, epigenetic deregulation, and increased cellular proliferation that eventually culminate in the carcinoma phenotype. Methods: Comparative whole exome sequencing of both primary and metastatic tumor tissues from four patients of stage IV lung adenocarcinoma patients with chest wall metastasis was performed. Both primary and metastatic tumors were diagnosed through biopsy followed by surgical resection. All tumor specimens were cut into several pieces to assess potential heterogenic clones within the tumor tissue. Adjacent normal lung tissue was also obtained to provide germline mutation background. Results: By modeling and analyzing progression of the cancer metastasis based on non-synonymous variants, we defined the extent of heterogeneity of cancer genomes and identified similar cancer evolution pattern in the four patients: metastasis was an early event occurring right after the primary cancer formation and evolution in the metastatic tumor was continuously and simultaneously in progression with that in the primary tumor. By characterizing the clonal hierarchy of genetic lesions, we further charted a pathway of oncogenic events along which genes may drive lung adenocarcinoma metastasis, such as TAS2R31 and UMODL1, involving in G-protein coupled receptor protein signaling pathway. Conclusion: The candidate genes identified in this study may become targets for the treatment of lung adenocarcinoma metastasis.

    Esophageal squamous cell carcinoma (ESCC) is one of the most frequent malignancies worldwide. Lymph node metastasis is the leading cause of death in ESCC patients. To identify early diagnostic and prognostic biomarkers of ESCC and elucidate underlying pathogenesis of the disease, a targeted metabolomics strategy based on liquid chromatography combined with tandem mass spectrometry was applied to explore tryptophan metabolism between ESCC patients, metastatic ESCC patients (mESCC), and healthy controls. Statistical analysis on metabolite expression abundance and compound concentration ratio was conducted to discriminate patients from healthy controls. The concentration ratio of kynurenine, 5-hydroxytryptophan, 5-hydroxyindole-3-acetic acid, 5-hydroxytryptamine to their precursor tryptophan were identified as potential biomarkers, presenting high diagnostic capacity for distinguishing ESCC and mESCC patients from healthy controls. Moreover, a prognostic prediction model was also built on these ratios to distinguish metastasis patients from non-metastasis patients successfully. The high performance of ESCC prediction models suggest that concentration ratios of compounds may be used as biomarkers for early diagnosis and prognosis of the disease. In addition, concentration ratios of compounds show a progressively increased trend from non-metastasis to metastasis patients compared with healthy controls, which is in accordance with process of malignant transformation of ESCC. This interested finding suggests that disturbed tryptophan metabolism is correlated to progression and metastasis of ESCC since concentration ratios of compounds reflect activity of enzymes involved in tryptophan metabolism. This study reveals the impact of tryptophan metabolism to tumorigenesis and metastasis of ESCC, which help biologists investigate mechanism of the disease. Copyright © 2017 Elsevier Inc.

    Migfilin is a novel cell–matrix adhesion protein known to interact with Vasodilator Stimulated Phosphoprotein (VASP) and be localized both at cell–matrix and cell–cell adhesions. To date there is nothing known about its role in hepatocellular carcinoma (HCC). As matrix is important in metastasis, we aimed to investigate the Migfilin's role in HCC metastasis using two human HCC cell lines that differ in their metastatic potential; non-invasive Alexander cells and the highly invasive HepG2 cells. We silenced Migfilin by siRNA and studied its effect on signaling and metastasis-related cellular properties. We show that Migfilin's expression is elevated in HepG2 cells and its silencing leads to upregulation of actin reorganization-related proteins, namely phosphor-VASP (Ser157 and Ser239), Fascin-1 and Rho-kinase-1, promoting actin polymerization and inhibiting cell invasion. Phosphor-Akt (Ser473) is decreased contributing to the upregulation of free and phosphor-β-catenin (Ser33/37Thr41) and inducing proliferation. Migfilin elimination upregulates Extracellular Signal–regulated kinase, which increases cell adhesion in HepG2 and reduces invasiveness. This is the first study to reveal that Migfilin inhibition can halt HCC metastasis in vitro, providing the molecular mechanism involved and presenting Migfilin as potential therapeutic target against HCC metastasis. - Highlights: • Migfilin is a cell–matrix and cell–cell adhesion protein known to interact with VASP. • Nothing is known about Migfilin's role in hepatocellular carcinoma (HCC). • We eliminated Migfilin from 2 HCC cell lines and studied in vitro metastasis. • Its silencing inhibits cell invasion and promotes adhesion in HepG2 invasive cells. • We provide molecular mechanism by which Migfilin elimination halts HCC metastasis.

    Spinal epidural extramedullary haematopoiesis is very rare in thalassaemia. A 27-year-old man with thalassaemia intermedia presented with symptoms and signs of spinal cord compression. MRI showed a thoracic spinal epidural mass, representing extramedullary haematopoietic tissue, compressing the spinal cord. Following radiotherapy, serial MRI revealed regression of the epidural mass and gradual resolution of spinal cord oedema. (orig.) With 3 figs., 6 refs.

    Spinal cord transection in children may occur following severe trauma such as a motor vehicle accident, and often without evidence of underlying skeletal injury. We report one case which showed cervical cord transection, where no evidence of underlying skeletal injury was seen on MR imaging, four weeks after trauma. When a neurologic deficit is present despite normal routine plain radiographs, further MR imaging is warranted to exclude a cord transection, as demonstrated in our patient

    Full Text Available Metastasis occurs with 50% of lung carcinomas, most commonly to lymph nodes, adrenal glands, liver, bone, and brain. It is extremely rare for lung cancer to present with symptoms of a gastrointestinal metastasis and even more so pertaining to the colon. To the best of our knowledge, only 12 such cases have been reported in the literature. We describe a case of a 71-year-old female presenting with refractory iron deficiency anemia that was found to have a lesion in the transverse colon. Pathology revealed adenocarcinoma of the lung and a subsequent lung lesion was discovered in a retrograde fashion.

    Aim of the present study is to report clinical characteristics and outcomes of patients treated in authors' hospital for GI metastasis from primary lung cancer, and to report and analyse the same data concerning patients retrieved from a systematic literature review. We performed a retrospective analysis of prospectively collected data, and a systematic review using the Meta-analysis Of Observational Studies in Epidemiology (MOOSE) guidelines. Ninety-one patients were included, 5 patients from the authors' hospital and 86 through PubMed database using the keywords "intestinal metastasis" AND "lung cancer". The median time between primary lung cancer diagnosis and GI metastasis diagnosis was 2 months and the median overall survival was 4 months. This group of patients present a poor prognosis and the gold standard treatment is not defined. None of the reported treatments had a significant impact on survival. Copyright © 2018 AEC.

    A 19-year-old man suffering from testicular choriocarcinoma presented to the dermatology department with a cutaneous metastasis on his head. This metastasis was the first sign of disease that led to medical consultation. Histopathology revealed cytotrophoblasts and syncytiotrophoblasts, the later expressing human chorionic gonadotropin antigen. Whole body computed tomography showed multiple metastases of the brain, lung, liver, bone, paraaortic lymph nodes and left uvea, the primary was found in the left testicle. Despite neurosurgical intervention and chemotherapy the patient died nine days after the biopsy of the cutaneous metastasis. Cutaneous metastases of testicular choriocarcinoma are exceptionally rare, with less than a dozen cases reported in the English-language literature. The present case highlights that testicular choriocarcinoma metastatic to the skin should be included in the differential of (poorly differentiated) cutaneous scalp tumors.

    Gingival metastases are very rare. We report the case of a 47 year-old man presenting with a gingival metastasis from a non small cell lung carcinoma. According to the literature, the most probable way of spread of such metastasis is hematogenous. Local implantation of cancer cells, present in patient's expectoration, in a fragile gingival may be an other pathway of lung cancer metastasizing in this region as we will try to describe in this case report. Cytological and/or histological investigation is needed to assess the malignant and the metastatic character of these gingival lesions. A rapid regression is observed after a flash of external beam radiation; nevertheless metastasis prognosis depends on the primary tumour progress. (authors)

    Full Text Available This report presents the case of a 70-year-old woman with a previous history of a left nephrectomy for renal cell carcinoma (RCC, who developed general malaise and fatigue. Abdominal computed tomography demonstrated an enhancing 6 × 7 cm necrotic lesion in the lower pole of the spleen suggestive of a metastasis. Given the highly suspicious nature of the lesion we proceeded to splenectomy. The tumour did not breach the splenic capsule, and there was no local diaphragmatic involvement. The mass was concluded to be a true metastasis of the original RCC rather than local recurrence of the disease. The causes of isolated solid splenic lesions are wide and varied, however a past or present history of malignancy should lead to a high index of suspicion for a splenic metastasis. We report an extremely unusual case of spread from a RCC.

    Plasticity changes of uninjured nerves can result in a novel neural circuit after spinal cord injury, which can restore sensory and motor functions to different degrees. Although processes of neural plasticity have been studied, the mechanism and treatment to effectively improve neural plasticity changes remain controversial. The present study reviewed studies regarding plasticity of the central nervous system and methods for promoting plasticity to improve repair of injured central nerves. The results showed that synaptic reorganization, axonal sprouting, and neurogenesis are critical factors for neural circuit reconstruction. Directed functional exercise, neurotrophic factor and transplantation of nerve-derived and non-nerve-derived tissues and cells can effectively ameliorate functional disturbances caused by spinal cord injury and improve quality of life for patients.

    Current knowledge regarding the distribution of acetylcholinesterase (ACHE) cholineacetyltranferase (ChAT) and cholinergic receptors in the spinal cord is presented as well as changes in these markers coupled to the degenerations in amyotrophic lateral sclerosis (ALS). The principal changes in ChAT and nicotonic receptors in rat hindleg muscles during denervation and reinnervation is discussed as a background for quantitative studies in human muscle biopsies. It is noted that thefirst published autoradiograph on spinal cord muscarinic receptors was from the rat, depicting an intense binding of radiolabeled quinuclikiny benzilate (tritium-QNB) in the ventral horn, and expecially in an apical part of the dorsal horn claimed to correspond to correspond to sustantia gelatinosa

    The distribution of somatostatin in the rat spinal cord was studied immunohistochemically with particular reference to the localization in the caudal centers that innervate the pelvic organs. For detailed studies of the laminar distribution of somatostatin the combination of immunohistochemistry...... and acetylcholinesterase enzyme histochemistry was employed. Deafferentation experiments were carried out to shed light on the origin of the somatostatin-containing axons. These experiments showed that the bulk of the spinal somatostatin has a spinal origin. The structures showing somatostatin immunoreactivity formed...... in the sacral parasympathetic intermediolateral nucleus. In contrast, very few appeared in the sympathetic nuclei. Immunoreactive somata were present in the surroundings of the central canal at all levels. Moreover, positive neurons were found in the intermediolateral nucleus of the sacral cord. By combined...

    Metastasis of malignant tumors to the kidney is clinically rare and often discovered by autopsy. Primary lymphoma and lung cancer are known that can metastasize to the kidney. Other malignant tumor metastasis to the kidney is very unusual. Primary cervical cancer metastasis to adjacent pelvic organs and lymph nodes are well known followed by abdominal solid organs such as the liver and adrenal glands. However, reported primary cervical cancer metastasis to the kidney is extremely rare and mostly appeared as bilateral multiple renal masses. We report here on a rare case of unilateral single renal metastasis from primary cervical cancer after concur- rent chemoradiotherapy.

    Full Text Available BACKGROUND Spinal cord tumours are relatively rare tumours and can present with a wide variety of symptoms. If they are not diagnosed early and treated immediately, they can lead to neurological deficits and disability. Therefore, accurate diagnosis is necessary, which will help in directing the therapy. Nowadays, MRI is the most commonly used modality for spinal cord tumour diagnosis unless there is a contraindication. The aim of this study was to study the demographic profile of patients with spinal cord tumours to assess the distribution, features, localisation and extent of spinal cord tumours by MRI and correlate the tissue characterisation by MRI with that of histopathological examination. MATERIALS AND METHODS A prospective study was conducted in the Departments of Radiodiagnosis, Neurosurgery and Pathology at SCBMCH, Cuttack, from October 2010 to October 2012. 52 patients diagnosed as having spinal cord tumours by clinical examination and MRI were followed till post-surgery discharge. RESULTS Out of the 52 patients with spinal cord tumours, 28 patients (54% were males and females made up around 46% (24 patients. Around 6% of the patients were in the paediatric age group. Our study showed that intradural extramedullary tumours 36/52 (69% were the commonest followed by intramedullary tumours 10/52 (19% and extradural tumours 6/52 (12%. Overall, schwannoma was the commonest spinal cord tumour accounting for 46.1% of the tumours. Out of 52 cases, MRI diagnosed 46 cases (88.46% correctly and misdiagnosed 6 cases. MRI was able to correctly diagnose 91.67% of the intradural extramedullary tumours, 90% of the intramedullary tumours and 66.67% of the extradural tumours. CONCLUSION MRI is the preoperative investigation of choice in the evaluation of spinal cord tumours. MRI can accurately diagnose spinal tumours and guide surgical resection.

  20. Robust, accurate and fast automatic segmentation of the spinal cord.

    Spinal cord segmentation provides measures of atrophy and facilitates group analysis via inter-subject correspondence. Automatizing this procedure enables studies with large throughput and minimizes user bias. Although several automatic segmentation methods exist, they are often restricted in terms of image contrast and field-of-view. This paper presents a new automatic segmentation method (PropSeg) optimized for robustness, accuracy and speed. The algorithm is based on the propagation of a deformable model and is divided into three parts: firstly, an initialization step detects the spinal cord position and orientation using a circular Hough transform on multiple axial slices rostral and caudal to the starting plane and builds an initial elliptical tubular mesh. Secondly, a low-resolution deformable model is propagated along the spinal cord. To deal with highly variable contrast levels between the spinal cord and the cerebrospinal fluid, the deformation is coupled with a local contrast-to-noise adaptation at each iteration. Thirdly, a refinement process and a global deformation are applied on the propagated mesh to provide an accurate segmentation of the spinal cord. Validation was performed in 15 healthy subjects and two patients with spinal cord injury, using T1- and T2-weighted images of the entire spinal cord and on multiecho T2*-weighted images. Our method was compared against manual segmentation and against an active surface method. Results show high precision for all the MR sequences. Dice coefficients were 0.9 for the T1- and T2-weighted cohorts and 0.86 for the T2*-weighted images. The proposed method runs in less than 1min on a normal computer and can be used to quantify morphological features such as cross-sectional area along the whole spinal cord.

    A spinal cord subependymoma is an uncommon, indolent, benign spinal cord tumor. It is radiologically similar to a spinal cord ependymoma, but surgical findings and outcomes differ. Gross total resection of the tumor is not always feasible. The present study was done to determine the clinical, radiological and pathological characteristics of spinal cord subependymomas. We retrospectively reviewed the medical records of ten spinal cord subependymoma patients (M : F=4 : 6; median 38 years; range, 21-77) from four institutions. The most common symptoms were sensory changes and/or pain in eight patients, followed by motor weakness in six. The median duration of symptoms was 9.5 months. Preoperative radiological diagnosis was ependymoma in seven and astrocytoma in three. The tumors were located eccentrically in six and were not enhanced in six. Gross total resection of the tumor was achieved in five patients, whereas subtotal or partial resection was inevitable in the other five patients due to a poor dissection plane. Adjuvant radiotherapy was performed in two patients. Neurological deterioration occurred in two patients; transient weakness in one after subtotal resection and permanent weakness after gross total resection in the other. Recurrence or regrowth of the tumor was not observed during the median 31.5 months follow-up period (range, 8-89). Spinal cord subependymoma should be considered when the tumor is located eccentrically and is not dissected easily from the spinal cord. Considering the rather indolent nature of spinal cord subependymomas, subtotal removal without the risk of neurological deficit is another option.

    The aim of the present study was to establish an animal liver metastasis model with human colon cancer and investigate the inhibitory effect of the wild type (WT) p53 gene combined with thymidine kinase/ganciclovir (TK/GCV) and cytosine deaminase/5-fluorocytosine (CD/5-FC) systems on liver metastasis of colon cancer. A nude mouse liver metastasis model with human colon cancer was established via a spleen cultivation method. A total of 32 nude mice were randomly divided into four groups, each group with eight mice. Group 1 mice received splenic injections of SW480 cells (control group), while group 2 mice were injected with SW480/p53 cells in the spleen. Group 3 mice were administered splenic injections of SW480/TK-CD cells, and GCV and 5-FC were injected into the abdominal cavity. Finally, group 4 mice received splenic injections of SW480/p53 cells mixed in equal proportion with SW480/TK-CD cells, as well as GCV and 5-FC injections in the abdominal cavity. These cells described were constructed in our laboratory and other laboratories. The number of liver metastatic tumors, the liver metastasis rate, conventional pathology, electron microscopy and other indicators in the nude mice of each group were compared and observed. The nude mouse liver metastasis model with human colon cancer was successfully established; the liver metastasis rate of the control group was 100%. The results demonstrated that the rate of liver metastasis in the nude mice in each treatment group decreased, as well as the average number of liver metastatic tumors. Furthermore, the effect of the treatment group with genetic combination (group 4) was the most effective, demonstrating that WTp53 had a synergistic effect with TK/GCV and CD/5-FC. Therefore, the present study successfully established a mouse model of liver metastasis with colon cancer by injecting human colon cancer cells in the spleen. Combined gene therapy was shown to have a synergistic effect, which effectively inhibited the

    Full Text Available Introduction: Acute Spinal Cord Injury (ASCI is one of the most common and important disorders in the field of neurosurgery. Progress achieved in relation to the care provided to repair spinal cord injuries have been taken from ancient times to the present day. Recently Neuroprotective therapies have attracted a lot of staff to approach the patient. Research scientists have shown that there is a possibility of recovery after spinal cord injury. Many pharmacological agents, Erythropoietin, in this field are used to reduce secondary damage after the primary insult and try to preserve nerve tissue. The aim of this study was to investigate the effect of Erythropoietin on sensory and motor status of patients with acute spinal cord injury. Materials and Methods: In this clinical trial, 60 patients with acute spinal cord injury in the Frankel classification, the category A to C, and the selection of matched Frankel class into two groups A and B (each group consisted of 30 patients was done. Group A underwent conventional treatment received methylprednisolone, were used erythropoietin and were compared after 4days,6-months intervals in terms of complete and incomplete cord injury  status with group B (that underwent only conventional treatment such as methylprednisolone. Results: In our study of two groups there were 16 patients with complete spinal cord injury and 44 patients were had incomplete SCI. In the period of 4 days after the onset of the study, patients with complete SCI in case and control group did not recover. In Patients with incomplete spinal cord injury in case group 13 of 21 patients (62% and 2 of 23 patients (9% in the control group were cured. In the period of 6 months after the study, 2 of 8 patients (25% in case group with complete cord had recovery. In the control group of patients with complete spinal cord injury didn't have any recovery. Also in incomplete SCI 12 of 19 patients (63% in case group and 5 of 21 patients (23% in the

    Sixteen patients with posttraumatic spinal cord cysts (PTSCC) were evaluated clinically and studied with metrizamide computed tomography (MCT). These patients presented months to years following a severe spinal cord injury, usually with new or progressively worsening neurological symptoms. The development of the PTSCC was unrelated to the location, type, and severity of injury, or to the time interval from the original injury. MCT showed that these cysts occur most frequently in normal or atrophic cords, they may be multiple, they most frequently are found in the dorsal portion of the cord, and they may vary along their length in width and position within the cord. Knowledge of this radiographic morphology is crucial to the surgical planning. The location of the cysts and the mode of their enlargement are correlated with anatomic features of the spinal cord and changes in cerebrospinal fluid dynamics. Cyst-to-subarachnoid space shunting relieves the majority of symptoms

    To analyze predictive factors for lymph node metastasis in early gastric cancer. We analyzed 1104 patients with early gastric cancer (EGC) who underwent a gastrectomy with lymph-node dissection from May 2003 through July 2011. The clinicopathologic factors and molecular markers were assessed as predictors for lymph node metastasis. Molecular markers such as microsatellite instability, human mutL homolog 1, p53, epidermal growth factor receptor (EGFR) and human epidermal growth factor receptor 2 (HER2) were included. The χ(2) test and logistic regression analysis were used to determine clinicopathologic parameters. Lymph node metastasis was observed in 104 (9.4%) of 1104 patients. Among 104 cases of lymph node positive patients, 24 patients (3.8%) were mucosal cancers and 80 patients (16.7%) were submucosal. According to histologic evaluation, the number of lymph node metastasis found was 4 (1.7%) for well differentiated tubular adenocarcinoma, 45 (11.3%) for moderately differentiated tubular adenocarcinoma, 36 (14.8%) for poorly differentiated tubular adenocarcinoma, and 19 (8.4%) for signet ring cell carcinoma. Of 690 EGC cases, 77 cases (11.2%) showed EGFR overexpression. HER2 overexpression was present in 110 cases (27.1%) of 406 EGC patients. With multivariate analysis, female gender (OR = 2.281, P = 0.009), presence of lymphovascular invasion (OR = 10.950, P tumor size, lymphovascular invasion and EGFR overexpression were predictive risk factors for lymph node metastasis in EGC.

  6. Spinal cord injury after conducting transcatheter arterial chemoembolization for costal metastasis of hepatocellular carcinoma

    2012-09-01

    Full Text Available Transcatheter arterial chemoembolization (TACE has been used widely to treat patients with unresectable hepatocellular carcinoma. However, this method can induce various adverse events caused by necrosis of the tumor itself or damage to nontumor tissues. In particular, neurologic side effects such as cerebral infarction and paraplegia, although rare, may cause severe sequelae and permanent disability. Detailed information regarding the treatment process and prognosis associated with this procedure is not yet available. We experienced a case of paraplegia that occurred after conducting TACE through the intercostal artery to treat hepatocellular carcinoma that had metastasized to the rib. In this case, TACE was attempted to relieve severe bone pain, which had persisted even after palliative radiotherapy. A sudden impairment of sensory and motor functions after TACE developed in the trunk below the level of the sternum and in both lower extremities. The patient subsequently received steroid pulse therapy along with supportive care and continuous rehabilitation. At the time of discharge the patient had recovered sufficiently to enable him to walk by himself, although some paresthesia and spasticity remained.

  7. Central nociceptive sensitization vs. spinal cord training: Opposing forms of plasticity that dictate function after complete spinal cord injury

    Directory of Open Access Journals (Sweden)

    Adam R Ferguson

    2012-10-01

    Full Text Available The spinal cord demonstrates several forms of plasticity that resemble brain-dependent learning and memory. Among the most studied form of spinal plasticity is spinal memory for noxious (nociceptive stimulation. Numerous papers have described central pain as a spinally-stored memory that enhances future responses to cutaneous stimulation. This phenomenon, known as central sensitization, has broad relevance to a range of pathological conditions. Work from the spinal cord injury (SCI field indicates that the lumbar spinal cord demonstrates several other forms of plasticity, including formal learning and memory. After complete thoracic SCI, the lumbar spinal cord can be trained by delivering stimulation to the hindleg when the leg is extended. In the presence of this response-contingent stimulation the spinal cord rapidly learns to hold the leg in a flexed position, a centrally mediated effect that meets the formal criteria for instrumental (response-outcome learning. Instrumental flexion training produces a central change in spinal plasticity that enables future spinal learning on both the ipsilateral and contralateral leg. However, if stimulation is given in a response-independent manner, the spinal cord develops central maladaptive plasticity that undermines future spinal learning on both legs. The present paper tests for interactions between spinal cord training and central nociceptive sensitization after complete spinal cord transection. We found that spinal training alters future central sensitization by intradermal formalin (24 h post-training. Conversely intradermal formalin impaired future spinal learning (24 h post-injection. Because the NMDA receptor has been implicated in formalin-induced central sensitization, we tested whether pretreatment with NMDA affects spinal learning. We found intrathecal NMDA impaired learning in a dose-dependent fashion, and that this effect endures for at least 24h. These data provide strong evidence for an

    Cell transplantation is a promising experimental treatment for spinal cord injury. The aim of the present study was to evaluate the efficacy of mononuclear cells from human umbilical cord blood in promoting functional recovery when transplanted after a contusion spinal cord injury. Female Wistar rats (12 weeks old) were submitted to spinal injury with a MASCIS impactor and divided into 4 groups: control, surgical control, spinal cord injury, and one cell-treated lesion group. Mononuclear cells from umbilical cord blood of human male neonates were transplanted in two experiments: a) 1 h after surgery, into the injury site at a concentration of 5 x 10 6 cells diluted in 10 µL 0.9% NaCl (N = 8-10 per group); b) into the cisterna magna, 9 days after lesion at a concentration of 5 x 10 6 cells diluted in 150 µL 0.9% NaCl (N = 12-14 per group). The transplanted animals were immunosuppressed with cyclosporin-A (10 mg/kg per day). The BBB scale was used to evaluate motor behavior and the injury site was analyzed with immunofluorescent markers to label human transplanted cells, oligodendrocytes, neurons, and astrocytes. Spinal cord injury rats had 25% loss of cord tissue and cell treatment did not affect lesion extension. Transplanted cells survived in the injured area for 6 weeks after the procedure and both transplanted groups showed better motor recovery than the untreated ones (P < 0.05). The transplantation of mononuclear cells from human umbilical cord blood promoted functional recovery with no evidence of cell differentiation

    Cell transplantation is a promising experimental treatment for spinal cord injury. The aim of the present study was to evaluate the efficacy of mononuclear cells from human umbilical cord blood in promoting functional recovery when transplanted after a contusion spinal cord injury. Female Wistar rats (12 weeks old) were submitted to spinal injury with a MASCIS impactor and divided into 4 groups: control, surgical control, spinal cord injury, and one cell-treated lesion group. Mononuclear cells from umbilical cord blood of human male neonates were transplanted in two experiments: a) 1 h after surgery, into the injury site at a concentration of 5 x 10{sup 6} cells diluted in 10 µL 0.9% NaCl (N = 8-10 per group); b) into the cisterna magna, 9 days after lesion at a concentration of 5 x 10{sup 6} cells diluted in 150 µL 0.9% NaCl (N = 12-14 per group). The transplanted animals were immunosuppressed with cyclosporin-A (10 mg/kg per day). The BBB scale was used to evaluate motor behavior and the injury site was analyzed with immunofluorescent markers to label human transplanted cells, oligodendrocytes, neurons, and astrocytes. Spinal cord injury rats had 25% loss of cord tissue and cell treatment did not affect lesion extension.

    The purpose of this study was to assess the usefulness of serial bone scintigraphy in the detection of skeletal and extraskeletal metastases in dogs with appendicular osteosarcoma. Twenty-six dogs with primary, appendicular osteosarcoma were entered into a limb-sparing protocol. Bone scintigraphy was performed upon presentation, after neoadjuvant therapy but prior to surgery and at selective intervals after limb-sparing surgery to evaluate for the presence of metastasis. Thoracic radiographs, and radiographs of other sites, were also made at the time of each bone scan. All dogs had a complete necropsy. No dog had bone or lung metastases detected prior to treatment. The bone scans, medical records, and radiographs of each dog were reviewed retrospectively. All but one dog developed metastatic disease. Bone metastatic sites were confirmed at necropsy in 12 of the 26 dogs. Seven of these 12 dogs had bone metastatic sites which were not producing clinical signs, i.e. an occult metastasis. In five of the seven dogs, the occult site was the first metastatic site detected. Extraskeletal metastases were identified scintigraphically in six of the 26 dogs, but these were clinically apparent prior to bone scintigraphy in each dog. Suspected malignant scintigraphic lesions were proven benign in six dogs. In five dogs with malignant bone lesions at necropsy the last bone scan prior to euthanasia was normal. The time interval between scintigraphy and necropsy was variable in these five dogs. All dogs without bone metastases at necropsy had normal bone scans. This study validates the usefulness of bone scintigraphy for detection of occult bone metastasis and improved ability for tumor staging in dogs with appendicular osteosarcoma

    Considering the advantages and disadvantages of lateral lymph node dissection in patients with advanced lower rectal cancer, it would be ideal to select candidates for lateral lymph node dissection by preoperative imaging study including magnetic resonance imaging (MRI). We have reported that the cut-off value of minimal diameter of lateral lymph node could be set at 6 mm for indication of lateral lymph node dissection. In the present study, we evaluated whether it would be appropriate to apply the cut-off value of minimal diameter of lateral lymph node in MRI. Forty-four patients with advanced lower rectal cancer underwent a curative surgery with lateral lymph node dissection or sampling from 1997 to 2009 in our institute. Among them, 25 patients received MRI preoperatively and analyzed. The images were obtained by a sagittal method that was diagonal along sacro-iliac joint with 5 mm thick sections. Lateral lymph node metastasis was detected in 5 cases, one side in 4 cases and both sides in 1 case. The sensitivity, specificity, positive predict value, and accuracy for predicting metastasis was 50%, 90%, 42.9% and 84.8% respectively, when the cut-off value of the minimal diameter was set at 6 mm in MRI. Our results indicated that a 6 mm set as the cut-off value of minimal diameter of lateral lymph node was suitable for the prediction of lateral lymph node metastasis since the accuracy was relatively high (84.8%), though it was hardly to detect metastatic lymph node less than 6 mm.

    Full Text Available Patients with Klippel-Feil Syndrome (KFS have congenital fusion of their cervical vertebrae due to a failure in the normal segmentation of the cervical vertebrae during the early weeks of gestation and also have myriad of other associated anomalies. Because of limited neck mobility, airway management in these patients can be a challenge for the anesthesiologist. We describe a unique case in which a dexmedetomidine infusion was used as sedation for an awake fiber-optic intubation in a parturient with Klippel-Feil Syndrome, who presented for elective cesarean delivery. A 36-yearold female, G2P1A0 with KFS (fusion of cervical vertebrae who had prior cesarean section for breech presentation with difficult airway management was scheduled for repeat cesarean delivery. After obtaining an informed consent, patient was taken in the operating room and non-invasive monitors were applied. Dexmedetomidine infusion was started and after adequate sedation, an awake fiberoptic intubation was performed. General anesthetic was administered after intubation and dexmedetomidine infusion was continued on maintenance dose until extubation. Klippel-Feil Syndrome (KFS is a rare congenital disorder for which the true incidence is unknown, which makes it even rare to see a parturient with this disease. Patients with KFS usually have other congenital abnormalities as well, sometimes including the whole thoraco-lumbar spine (Type III precluding the use of neuraxial anesthesia for these patients. Obstetric patients with KFS can present unique challenges in administering anesthesia and analgesia, primarily as it relates to the airway and dexmedetomidine infusion has shown promising result to manage the airway through awake fiberoptic intubation without any adverse effects on mother and fetus.

    Full Text Available Brain metastases arise in 10%–40% of all cancer patients. Up to one third of the patients do not have previous cancer history. We report a case of a 67-years-old male patient who presented with confusion, tremor, and apraxia. A brain MRI revealed an isolated right temporal lobe lesion. A thorax-abdomen-pelvis CT scan showed no primary lesion. The patient underwent a craniotomy with gross-total resection. Histopathology revealed an intestinal-type adenocarcinoma. A colonoscopy found no primary lesion, but a PET-CT scan showed elevated FDG uptake in the appendiceal nodule. A right hemicolectomy was performed, and the specimen showed a moderately differentiated mucinous appendiceal adenocarcinoma. Whole brain radiotherapy was administrated. A subsequent thorax-abdomen CT scan revealed multiple lung and hepatic metastasis. Seven months later, the patient died of disease progression. In cases of undiagnosed primary lesions, patients present in better general condition, but overall survival does not change. Eventual identification of the primary tumor does not affect survival. PET/CT might be a helpful tool in detecting lesions of the appendiceal region. To the best of our knowledge, such a case was never reported in the literature, and an appendiceal malignancy should be suspected in patients with brain metastasis from an undiagnosed primary tumor.

    Full Text Available Conservation of major signaling pathways between humans and flies has made Drosophila a useful model organism for cancer research. Our understanding of the mechanisms regulating cell growth, differentiation and development has been considerably advanced by studies in Drosophila. Several recent high profile studies have examined the processes constraining the metastatic growth of tumor cells in fruit fly models. Cell invasion can be studied in the context of an in vivo setting in flies, enabling the genetic requirements of the microenvironment of tumor cells undergoing metastasis to be analyzed. This Perspective discusses the strengths and limitations of Drosophila models of cancer invasion and the unique tools that have enabled these studies. It also highlights several recent reports that together make a strong case for Drosophila as a system with the potential for both testing novel concepts in tumor progression and cell invasion, and for uncovering players in metastasis.

    Cancer growth dynamics, commonly simulated with a Gompertzian model, is analyzed in the framework of a more recent and realistic model. In particular, we consider the setting of a tumor embedded in a host organ and investigate their interaction. We assume that, at least in some cases, tumor metastasis may be triggered by an 'energetic crisis', when the tumor exceeds the 'carrying capacity' of the host organ. As a consequence, dissemination of clusters of cancer cells is set in motion, with a statistical probability given by a Poisson distribution. The model, although still at a preclinical level, is fully quantitative and is applied, as an example, to the case of prostate cancer. The results confirm that, at least for the more aggressive cancers, metastasis starts very early during tumorigenesis and a quantitative link is found between the tumor's doubling time, its 'aggressiveness' and the metastatic potential.

    BACKGROUND: Adenocarcinoma of the gastroesophageal junction (GEJ) has a poor prognosis and survival rates significantly decreases if lymph node metastasis is present. An extensive lymphadenectomy may increase chances of cure, but may also lead to further postoperative morbidity and mortality....... Therefore, the optimal treatment of cardia cancer remains controversial. A systematic review of English publications dealing with adenocarcinoma of the cardia was conducted to elucidate patterns of nodal spread and prognostic implications. METHODS: A systematic literature search based on PRISMA guidelines...... identifying relevant studies describing lymph node metastasis and the associated prognosis. Lymph node stations were classified according to the Japanese Gastric Cancer Association guidelines. RESULTS: The highest incidence of metastasis is seen in the nearest regional lymph nodes, station no. 1...

    Association of aberrant glycosylation with melanoma progression is based mainly on analyses of cell lines. Here we present a systems-based study of glycomic changes and corresponding enzymes associated with melanoma metastasis in patient samples. Upregulation of core fucosylation (FUT8) and downregulation of α-1,2 fucosylation (FUT1, FUT2) were identified as features of metastatic melanoma. Using both in vitro and in vivo studies, we demonstrate FUT8 is a driver of melanoma metastasis which, when silenced, suppresses invasion and tumor dissemination. Glycoprotein targets of FUT8 were enriched in cell migration proteins including the adhesion molecule L1CAM. Core fucosylation impacted L1CAM cleavage and the ability of L1CAM to support melanoma invasion. FUT8 and its targets represent therapeutic targets in melanoma metastasis.

    2007-01-01

    We report two cases of primary uveal melanoma with metastatic involvement of the contralateral eye. Two female patients presented with primary choroidal melanoma. In the first case, primary enucleation of the affected eye was performed. Two years later, systemic tumor spread with contralateral choroidal melanoma was detected. A decision for observation of the ocular metastasis was made. In the second case, systemic tumor spread was already evident at time of initial diagnosis of the ocular melanoma. Six months later, a choroidal metastasis was detected in the fellow eye. Again, observation was recommended. In conclusion, systemic spread of primary choroidal melanoma may include a choroidal metastasis to the contralateral eye. Observation of the second affected eye may be prescribed.

    2010-05-01

    Full Text Available Intrathoracic endotracheal metastasis from a very distant site is extremely rare. We report the first case of such a disease in a 68-year-old man with nasopharyngeal carcinoma who presented with a cough and hemoptysis 34 months after finishing radiotherapy. Prior to tracheal metastasis, he developed a solitary metastasis in the lung and underwent chemotherapy followed by radiotherapy. Computed tomography showed the presence of an enlarged lymph node in the para-aortic arch. Fiberoptic bronchoscopy revealed an endotracheal tumor 1 cm above the carina. Histological and immunohistochemical analyses confirmed its nasopharyngeal origin. He was treated with conventional radiotherapy and three-dimensional conformal radiotherapy; complete tumor remission was achieved. He died of nonmalignant disease with no signs of tumor recurrence 2 years after treatment completion. Radiotherapy may be an appropriate management approach to achieve long-term tumor control for this disease.

    Vocal cord paralysis is a common cause of hoarseness. It may be secondary to many types of lesions along the cranial nerve X pathway and its branches, particularly the laryngeal recurrent nerves. Despite the idiopathic nature of a great number of cases, imaging methods play a very significant role in the investigation of etiologic factors, such as thyroid and esophagus neoplasias with secondary invasion of the laryngeal recurrent nerves. Other conditions such as aortic and right subclavian artery aneurysms also may be found. The knowledge of local anatomy and related diseases is of great importance for the radiologist, so that he can tailor the examination properly to allow an appropriate diagnosis and therapy planning. Additionally, considering that up to 35% of patients with vocal cord paralysis are asymptomatic, the recognition of radiological findings indicative of this condition is essential for the radiologist who must warn the referring physician on the imaging findings. In the present study, the authors review the anatomy and main diseases related to vocal cord paralysis, demonstrating them through typical cases evaluated by computed tomography and magnetic resonance imaging, besides describing radiological findings of laryngeal abnormalities indicative of this condition.

    Full Text Available Breast metastases from extramammary neoplasms are extremely rare, and even more so is metastasis of colon cancer to the breast. Despite its rarity, metastatic disease to the breast is an important diagnostic issue because its treatment differs greatly from that of primary cancer. Proper diagnosis of this rare event requires an accurate clinical history, proper immunohistochemical workup, and a high level of suspicion.

    Tumors metastasizing from distant regions to the oral and maxillofacial region are uncommon, comprising only 1%-2% of all malignancies. Cholangiocarcinoma is a malignancy that arises from cholangiocytes, which are epithelial cells that line the bile ducts. These cancers are difficult to diagnose and have a poor prognosis. In this paper, we report a rare case of mandibular metastasis of cholangiocarcinoma diagnosed at the primary site and discuss the radiographic findings observed in this case.

    Full Text Available Malignant melanoma of the vagina, a very rare malignancy, has a notoriously aggressive behavior associated with a high risk of local recurrence and distant metastasis. At present, there are various treatment options for this disease but no standard guideline. We describe a case of a 54-year-old woman with a locally advanced melanoma of the vagina, who underwent radical surgery, biochemotherapy with interferon-α-2b, chemotherapy, radiotherapy, and repeat excision of local recurrent lesions and brain metastasis. In conclusion, malignant melanoma of the vagina has a high risk for local recurrence. Repeated local excision followed by biochemotherapy is a tolerable treatment.

    2017-08-01

    Full Text Available Decades of cancer research have unraveled genetic, epigenetic and molecular pathways leading to plausible therapeutic targets; many of which hold great promise in improving clinical outcomes. Metastatic tumors become evident early on and are one of the major causes of cancer-related fatalities worldwide. This review depicts the sequential events of cancer metastasis. Genetic and epigenetic heterogeneity influences local tumor cell invasion, intravasation, survival in circulation, extravasation and colonization to distant sites. Each sequential event is associated with heterogeneous tumor microenvironment, gain of competence, unique population of cancer stem cells (CSCs, circulatory pathway, compatible niche and immune system support. A tight regulation of metastasis-promoting mechanisms and, in parallel, evading inhibitory mechanisms contribute to the severity and site of metastasis. A comprehensive understanding of tumor cell fate as an individual entity, as well as in combination with different promoting factors and associated molecular mechanisms, is anticipated in the coming years. This will enable scientists to depict design strategies for targeted cancer therapies.

    Accumulating evidences have demonstrated that mesenchymal stem cells (MSC) could be recruited to the tumor microenvironment. Umbilical cord mesenchymal stem cells (UCMSC) were attractive vehicles for delivering therapeutic agents against cancer. Nevertheless, the safety of UCMSC in the treatment of tumors including hepatocellular carcinoma (HCC) was still undetermined. In this study, an in vitro co-culture system was established to evaluate the effect of UCMSC on the cell growth, cancer stem cell (CSC) characteristics, drug resistance, metastasis of 3D-cultured HCC cells, and the underlying mechanism was also investigated. It was found that after co-cultured with UCMSC, the metastatic ability of 3D-cultured HCC cells was significantly enhanced as indicated by up-regulation of matrix metalloproteinase (MMP), epithelial-mesenchymal transition (EMT)-related genes, and migration ability. However, cell growth, drug resistance and CSC-related gene expression of HCC cells were not affected by UCMSC. Moreover, EMT was reversed, MMP-2 expression was down-regulated, and migration ability of HCC cell was significantly inhibited when TGF-β receptor inhibitor SB431542 was added into the co-culture system. Therefore, these data indicated that UCMSC could significantly enhance the tumor cell metastasis, which was due to the EMT of HCC cells induced by TGF-β.

  13. Ethical issues relating the the banking of umbilical cord blood in Mexico

    2009-08-01

    Full Text Available Abstract Background Umbilical cord banks are a central component, as umbilical cord tissue providers, in both medical treatment and scientific research with stem cells. But, whereas the creation of umbilical cord banks is seen as successful practice, it is perceived as a risky style of play by others. This article examines and discusses the ethical, medical and legal considerations that arise from the operation of umbilical cord banks in Mexico. Discussion A number of experts have stated that the use of umbilical cord goes beyond the mere utilization of human tissues for the purpose of treatment. This tissue is also used in research studies: genetic studies, studies to evaluate the effectiveness of new antibiotics, studies to identify new proteins, etc. Meanwhile, others claim that the law and other norms for the functioning of cord banks are not consistent and are poorly defined. Some of these critics point out that the confidentiality of donor information is handled differently in different places. The fact that private cord banks offer their services as "biological insurance" in order to obtain informed consent by promising the parents that the tissue that will be stored insures the health of their child in the future raises the issue of whether the consent is freely given or given under coercion. Another consideration that must be made in relation to privately owned cord banks has to do with the ownership of the stored umbilical cord. Summary Conflicts between moral principles and economic interests (non-moral principles cause dilemmas in the clinical practice of umbilical cord blood storage and use especially in privately owned banks. This article presents a reflection and some of the guidelines that must be followed by umbilical cord banks in order to deal with these conflicts. This reflection is based on the fundamental notions of ethics and public health and seeks to be a contribution towards the improvement of umbilical cord banks

    Ghost artifacts are a major contributor to degradation of spinal cord diffusion tensor images. A multi-stage post-processing pipeline was designed, implemented and validated to automatically remove ghost artifacts arising from reduced field of view diffusion tensor imaging (DTI) of the pediatric spinal cord. A total of 12 pediatric subjects including 7 healthy subjects (mean age=11.34years) with no evidence of spinal cord injury or pathology and 5 patients (mean age=10.96years) with cervical spinal cord injury were studied. Ghost/true cords, labeled as region of interests (ROIs), in non-diffusion weighted b0 images were segmented automatically using mathematical morphological processing. Initially, 21 texture features were extracted from each segmented ROI including 5 first-order features based on the histogram of the image (mean, variance, skewness, kurtosis and entropy) and 16s-order feature vector elements, incorporating four statistical measures (contrast, correlation, homogeneity and energy) calculated from co-occurrence matrices in directions of 0°, 45°, 90° and 135°. Next, ten features with a high value of mutual information (MI) relative to the pre-defined target class and within the features were selected as final features which were input to a trained classifier (adaptive neuro-fuzzy interface system) to separate the true cord from the ghost cord. The implemented pipeline was successfully able to separate the ghost artifacts from true cord structures. The results obtained from the classifier showed a sensitivity of 91%, specificity of 79%, and accuracy of 84% in separating the true cord from ghost artifacts. The results show that the proposed method is promising for the automatic detection of ghost cords present in DTI images of the spinal cord. This step is crucial towards development of accurate, automatic DTI spinal cord post processing pipelines. Copyright © 2017 Elsevier Inc. All rights reserved.

    To assess relative diagnostic value of Ga-67 planar, Ga-67 SPECT, and CT images for detection of head and neck tumors and cervical lymph node metastasis. Thirty eight patients of pathologically proven head and neck tumors including squamous cell carcinomas(n=32), malignant lymphomas(n=3), undifferentiated carcinomas(n=2), adenocarcinomas(n=1) were enrolled in this study. Ga-67 planar and SPECT images were obtained with intravenous injection of 5mCi of Ga-67 citrate. On the basis of 30 and 20 mm in the greatest diameter of cervical lymph nodes, we compared lesion detectability of Ga-67 planar, SPECT, and CT. Thirty eight cases of head and neck tumors were detected in 29 cases (76.3%) with Ga-67 planar image, 37 cases (97.3%) with Ga-67 SPECT, and 32 cases (84.2%) with CT. 25 of 32 squamous cell carcinomas were positive with Ga-67 planar image and all of 32 cases with Ga-67 SPECT. Both of two undifferentiated carcinomas were positive with Ga-67 planar and SPECT images. Two of three malignant lymphomas were positive with Ga-67 planar image and all of three with Ga-67 SPECT. Eight of nine tumors were negative with Ga-67 planar image and those were less than 30 mm. One case of adenocarcinoma was negative with Ga-67 planar and SPECT images. Seven of nine lymph nodes greater than 30 mm were positive with Ga-67 planar image and all of nine with Ga-67 SPECT. On the basis of 20 mm in greatest diameter, 16 of 21 lymph nodes greater than 20 mm were positive with Ga-67 planar and SPECT images. CT providing better resolution than Ga-67 scan permitted analysis of size and location of metastatic cervical nodes, however primary tumors of oral cavity, vocal cord, and nasopharynx were often not detected on CT when metallic and motion artifacts were present, where Ga-67 SPECT was useful. Ga-67 SPECT enabled better anatomical localization than Ga-67 planar image and was useful in detection of lymph nodes greater than 30 mm

    Somatosensory evoked potentials (S.E.P.) were used to examine twelve patients who had slow compressive lesions of the spinal cord (ten cases of spondylotic myelopathy, one neurinoma, one metastasis of a vertebral body). 73 per cent of the recordings were found to be abnormally reduced in amplitude, and/or showed prolonged latency times aa regards the primary and secondary complex. Patients with a clinical lesion of the dorsal column showed a clear reduction in amplitude in the recordings (sometimes coupled with slowed latency), especially in the primary complex. Patients with symptoms indicative of an injury to the ventrolateral region of the spinal cord showed tracings with alterations most of all related to the secondary complex. In 76 per cent of cases, the somatosensory evoked potentials were in accordance with the level of the compression, the degree of invalidity, and the clinical picture.

    We report a rare case of spermatic cord metastasis from colon cancer. A man in his 50s underwent extended right hemicolectomy for transverse colon cancer followed by resection of a peritoneal recurrence. After receiving adjuvant chemotherapy for 6 months, he became aware of a right inguinal mass. A spermatic cord tumor was noted on computed tomography(CT) and FDG/PET-CT. He underwent radical orchiectomy. The resected tumor was histologically compatible with the colon cancer. Although he received additional chemotherapy, right inguinal recurrence was resected 6 months after orchiectomy. Colon cancer is the second most common origin, after gastric cancer, of metastatic spermatic tumor. As several metastatic routes have been reported, peritoneal seeding is mostly suspected in this case.

    61 year old female presented with chief complaints of headache for 30 days, fever for 10 days, altered behavior for 10 days and convulsion for 2 days. She was diagnosed and treated as a case of carcinoma of left breast 5 years ago. MRI brain showed a lobulated lesion in the left frontal lobe. She came to our hospital for whole brain radiation as a diagnosed case of carcinoma of breast with brain metastasis. Review of MRI brain scan, revealed metastasis or query infective pathology. MR spectroscopy of the lesion revealed choline: creatinine and choline: NAA (N-Acety- laspartate) ratios of 1.6 and 1.5 respectively with the presence of lactate within the lesion suggestive of infective pathology. She underwent left fronto temporal craniotomy and evacuation of abscess and subdural empyema. Gram stain showed gram positive cocci. After 1 month of evacuation and treatment she was fine. This case suggested a note of caution in every case of a rapidly evolving space-occupying lesion independent of the patient’s previous history

    Full Text Available Abstract Background Secondary involvement of the thyroid gland by malignant metastases is uncommon. Acute respiratory crisis due to infiltration of the upper airways is a recognised complication of anaplastic thyroid carcinoma or thyroid lymphoma. Renal cell carcinoma is a tumour that metastasizes diffusely and in an unpredictable manner. Case presentation We report a case of a 73-year-old man with a painful neck mass, dyspnoea, stridor and dysphonia that was evaluated in emergency. A right radical nephrectomy for renal cell carcinoma was performed 8 years previously. An emergency endotracheal intubation was followed by total thyroidectomy. Histological examination confirmed the diagnosis of thyroid metastasis from renal cell carcinoma. Conclusion A literature review regarding emergency treatment for acute respiratory compromise resulting from secondary thyroid tumours was undertaken. Only two cases of metastatic colon cancer and one case of metastatic meningioma requiring emergency thyroidectomy for acute respiratory failure are reported in the literature. This appears to be the first case of emergency surgery performed for acute respiratory compromise due to thyroid metastasis from renal cell carcinoma.

    Metastatic penile carcinoma derived from cholangiocarcinoma (CCA) has not been previously reported in the literature. Common metastatic sites for CCA include the regional lymph nodes and adjacent organs. CCAs are not highly vascularised tumours, making hematogenous metastases uncommon. Hematogenous CCA metastases commonly occur at distant organs such as the lungs, adrenal glands, and bones. Median survival for patients with metastatic disease is generally less than 1 year. A 74-year-old Caucasian man consulted us after having undergone penile ultrasonography for pain and increased thickness at the base of the penis after self-examination. The patient presented with a history of hepatitis C-related cirrhosis and intrahepatic CCA, diagnosed 3 years previously. A biopsy of the corpora cavernosa on both sides revealed a carcinoma harbouring the same histological and immunophenotypical features as the primary hepatic lesion. To date, there is no case of penile or urogenital system metastasis from CCA described in the literature. Therefore, this article represents the first case report of penile metastasis from CCA.
